Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets

ChainLink - Rank 97 with no competitors. Undervalued Gem?

What Does ChainLink Do?
In a nutshell, ChainLink aims to solve the connectivity problem, a key limiting factor for smart contract usability, and whilst it's an ERC-20 token it will not be limited to just the Ethereum blockchain.
What makes $LINK so special? Well, it's the first decentralized oracle network; allowing anyone to securely provide smart contracts with access to key external data, off-chain payments and any other API capabilities. Anyone who has a data feed, useful off-chain service such as local payments, or any other API, can now provide them directly to smart contracts in exchange for LINK tokens.
Partnerships
I will keep this brief, as you can see a full list of current and potential partnerships on https://www.reddit.com/LINKTradecomments/7mob78/list_of_chainlinks_partnershipsprojects_using/
But the main ones to look at are
The Pros
ChainLink has steadily been gaining traction ever since its downfall after the 4chan/reddit SIBOS hypetrain crash (post September). It's remained around the 90-100 rank mark and has yet to really "moon".
The Cons
So what makes ChainLink valuable?
The LINK token is used by smart contract owners to pay chainlink nodes for getting data from them and the more LINKs an oracle node has, the more reputable it is. So oracle node providers are incentivized to hold as much LINKs in their chainlink nodes to appear more reputable to the chainlink network, gaining more usage and profit
(Taken from a comment on https://www.reddit.com/CryptoCurrency/comments/7nwis4/why_i_believe_chainlink_link_is_the_most/)
Most importantly, LINK can (and will be) used for data request penalty payments to ensure that node operators provide the requested data. Penalty payments are LINK tokens that are required to be held in escrow by the smart contract. They are paid to the smart contract creator in the event any of the node operators do not meet the required data requests as stated in the smart contract. This provides an incentive for smart contract creators to trust node operators, knowing that they have a form of financial insurance (the penalty payment) in the event a node (or nodes) submit bad data.
For information that will trigger high value smart contracts, smart contract owners will want to require a proportionate amount of link to be held in escrow as penalty payments by the node operators. When link is tied up for penalty payments, it is released over the life of the contract. For example, let’s say party A wants an API snapshot sent every day for 30 days. If the penalty payment for the contract is 300 LINK (per node operator), then each node operator will have 10 LINK released to them at the end of each day – receiving the full 300 LINK at the end of the 30 days if they successfully performed the data request the smart contract asked for. Now imagine the smart contract creator wanted 10 node operators. That means 3000 LINK is taken off the market immediately, and 100 of that 3000 is released each day from the smart contract to the individual node operators (10 each per operator, assuming they provided the requested data). A cycle will be created where more and more smart contracts will make requests and node operators will be limited only by the availability of their LINK tokens to be used for penalty payments.
Add it all together and you have a singular payment method for a desired network (the most secure external data oracle), lots of supply constantly locked up to have enough link for signaling purposes (the reputation boost for a node operator), financial insurance for smart contract creators (penalty payments) for increasingly valuable triggering data in a wide variety of smart contracts, and a network poised for growth as more adapters are built and more API’s become available so that dapps can thrive on any blockchain network. Yes LINk is an ERC20 token, but it is blockchain agnostic and the adapter network can continue to grow.
LINK can also be staked!
LINK staking is another big thing that will do wonders for Chainlink's valuation. Turns out Chainlink oracles can be made into pools, similar to mining pools on bitcoin and ethereum where multiple people come and put their LINKs together to run a more secure oracle node and distribute the profits fairly between each other. This will be huge as it will effectively allow you to stake your LINK tokens and earn more of them passively without doing anything. One such pool in development is LinkPool (http://www.linkpool.io/).
Where do i buy and store LINK?
You can currently buy LINK at the following exchanges;
As an ERC-20 token, you can store LINK on your ledger or MEW wallets.
Here is a well written guide on how to purchase LINK https://www.reddit.com/LINKTradecomments/7gglfv/how_to_buy_link_chainlink_token/

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.
see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
In Hub governance all stakers vote, the validators vote is superseded if the delegator votes directly
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.
Ethermint
Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.
You can find out more about Ethermint here and here

IBC

IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/qr4k6cxtmba31.png?width=1100&format=png&auto=webp&s=d79871767ced4bcb0b2632cc137c118f70c3863a
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

https://preview.redd.it/qn7895rumba31.png?width=770&format=png&auto=webp&s=96d9d808b2284f87d45fa0bd7b8bff297c86c2da
This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344
Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.

see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1

Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50

Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

I wrote a 30,000 ft. "executive summary" intro document for cryptos. Not for you, for your non-technical parents or friends.

This document was originally written for my dad, an intelligent guy who was utterly baffled about the cryptocurrency world. The aim was to be extremely concise, giving a broad overview of the industry and some popular coins while staying non-technical. For many of you there will be nothing new here, but recognize that you are in the 0.001% of the population heavily into crypto technology.
I've reproduced it for Reddit below, or you can find the original post here on my website. Download the PDF there or hit the direct link: .PDF version.

Background

This document is purely informational. At the time of writing there are over 1000 cryptocurrencies (“cryptos”) in a highly volatile, high risk market. Many of the smaller “altcoins” require significant technical knowledge to store and transact safely. I advise you to carefully scrutinize each crypto’s flavor of blockchain, potential utility, team of developers, and guiding philosophy, before making any investment [1] decisions. With that out of the way, what follows are brief, extremely high-level summaries of some cryptos which have my interest, listed in current market cap order. But first, some info:
Each crypto is a different implementation of a blockchain network. Originally developed as decentralized digital cash, these technologies have evolved into much broader platforms, powering the future of decentralized applications across every industry in the global economy. Without getting into the weeds, [2] most cryptos work on similar principles:
Distributed Ledgers Each node on a blockchain network has a copy of every transaction, which enables a network of trust that eliminates fraud. [3]
Decentralized “Miners” comprise the infrastructure of a blockchain network. [4] They are monetarily incentivized to add computing power to the network, simultaneously securing and processing each transaction. [5]
Peer-to-peer Cryptos act like digital cash-- they require no third party to transact and are relatively untraceable. Unlike cash, you can back them up.
Global Transactions are processed cheaply and instantly, anywhere on Earth. Using cryptos, an African peasant and a San Francisco engineer have the same access to capital, markets, and network services.
Secure Blockchains are predicated on the same cryptographic technology that secures your sensitive data and government secrets. They have passed seven years of real-world penetration testing with no failures. [6]

Bitcoin (BTC)

The first cryptocurrency. As with first movers in any technology, there are associated pros and cons. Bitcoin has by far the strongest brand recognition and deepest market penetration, and it is the only crypto which can be used directly as a currency at over 100,000 physical and web stores around the world. In Venezuela and Zimbabwe, where geopolitical events have created hyperinflation in the centralized fiat currency, citizens have moved to Bitcoin as a de facto transaction standard. [7]
However, Bitcoin unveiled a number of issues that have been solved by subsequent cryptos. It is experiencing significant scaling issues, resulting in high fees and long confirmation times. The argument over potential solutions created a rift in the Bitcoin developer community, who “forked” the network into two separate blockchains amidst drama and politicking in October 2017. Potential solutions to these issues abound, with some already in place, and others nearing deployment.
Bitcoin currently has the highest market cap, and since it is easy to buy with fiat currency, the price of many smaller cryptos (“altcoins”) are loosely pegged to its price. This will change in the coming year(s).

Ethereum (ETH)

Where Bitcoin is a currency, Ethereum is a platform, designed as a foundational protocol on which to develop decentralized applications (“Dapps”). Anyone can write code and deploy their program on the global network for extremely low fees. Just like Twitter wouldn’t exist without the open platform of the internet, the next world-changing Dapp can’t exist without Ethereum.
Current Dapps include a global market for idle computing power and storage, peer-to-peer real estate transactions (no trusted third party for escrow), identity networks for governments and corporations (think digital Social Security card), and monetization strategies for the internet which replace advertising. Think back 10 years to the advent of smartphones, and then to our culture today-- Ethereum could have a similar network effect on humanity.
Ethereum is currently the #2 market cap crypto below Bitcoin, and many believe it will surpass it in 2018. It has a large, active group of developers working to solve scaling issues, [8] maintain security, and create entirely new programming conventions. If successful, platforms like Ethereum may well be the foundation of the decentralized internet of the future.

Ripple (XRP)

Ripple is significantly more centralized than most crypto networks, designed as a backbone for the global banking and financial technology (“fintech”) industries. It is a network for exchanging between fiat currencies and other asset classes instantly and cheaply, especially when transacting cross-border and between separate institutions. It uses large banks and remittance companies as “anchors” to allow trading between any asset on the network, and big names like Bank of America, American Express, RBC, and UBS are partners. The utility of this network is global and massive in scale.
It is extremely important to note that not all cryptos have the same number of tokens. Ripple has 100 Billion tokens compared to Bitcoin’s 21 Million. Do not directly compare price between cryptos. XRP will likely never reach $1k, [9] but the price will rise commensurate with its utility as a financial tool.
In some sense, Ripple is anathema to the original philosophical vision of this technology space. And while I agree with the cyberpunk notion of decentralized currencies, separation of money and state, this is the natural progression of the crypto world. The internet was an incredible decentralized wild west of Usenet groups and listservs before Eternal September and the dot-com boom, but its maturation affected every part of global society.

Cardano (ADA)

Cardano’s main claim to fame: it is the only crypto developed using academic methodologies by a global collective of engineers and researchers, built on a foundation of industry-leading, peer-reviewed cryptographic research. The network was designed from first-principles to allow scalability, system upgrades, and to balance the privacy of its users with the security needs of regulators.
One part of this ecosystem is the Cardano Foundation, a Swiss non-profit founded to work proactively with governments and regulatory bodies to institute legal frameworks around the crypto industry. Detractors of Cardano claim that it doesn’t do anything innovative, but supporters see the academic backing and focus on regulation development as uniquely valuable.

Stellar Lumens (XLM)

Stellar Lumens and Ripple were founded by the same person. They initially shared the same code, but today the two are distinct in their technical back-end as well as their guiding philosophy and development goals. Ripple is closed-source, for-profit, deflationary, and intended for use by large financial institutions. Stellar is open-source, non-profit, inflationary, and intended to promote international wealth distribution. As such, they are not direct competitors.
IBM is a major partner to Stellar. Their network is already processing live transactions in 12 currency corridors across the South Pacific, with plans to process 60% of all cross-border payments in the South Pacific’s retail foreign exchange corridor by Q2 2018.
Beyond its utility as a financial tool, the Stellar network may become a competitor to Ethereum as a platform for application development and Initial Coin Offerings (“ICOs”). The theoretical maximum throughput for the network is higher, and it takes less computational power to run. The Stellar development team is highly active, has written extensive documentation for third-party developers, and has an impressive list of advisors, including Patrick Collison (Stripe), Sam Altman (Y Combinator), and other giants in the software development community.

Iota (IOT)

Iota was developed as the infrastructure backbone for the Internet of Things (IoT), sometimes called the machine economy. As the world of inanimate objects is networked together, their need to communicate grows exponentially. Fridges, thermostats, self-driving cars, printers, planes, and industrial sensors all need a secure protocol with which to transact information.
Iota uses a “Tangle” instead of a traditional blockchain, and this is the main innovation driving the crypto’s value. Each device that sends a transaction confirms two other transactions in the Tanlge. This removes the need for miners, and enables unique features like zero fees and infinite scalability. The supply of tokens is fixed forever at 2.8*1015, a staggeringly large number (almost three thousand trillion), and the price you see reported is technically “MIOT”, or the price for a million tokens.

Monero (XMR)

The most successful privacy-focused cryptocurrency. In Bitcoin and most other cryptos, anyone can examine the public ledger and trace specific coins through the network. If your identity can be attached to a public address on that network, an accurate picture of your transaction history can be built-- who, what, and when. Monero builds anonymity into the system using strong cryptographic principles, which makes it functionally impossible to trace coins, [10] attach names to wallets, or extract metadata from transactions. The development team actively publishes in the cryptography research community.
Anonymous transactions are not new-- we call it cash. Only in the past two decades has anonymity grown scarce in the first-world with the rise of credit cards and ubiquitous digital records. Personal data is becoming the most valuable resource on Earth, and there are many legitimate reasons for law-abiding citizens to want digital privacy, but it is true that with anonymity comes bad actors-- Monero is the currency of choice for the majority of black market (“darknet”) transactions. Similarly, US Dollars are the main vehicle for the $320B annual drug trade. An investment here should be based on the underlying cryptographic research and technology behind this coin, as well as competitors like Zcash. [11]

RaiBlocks (XRB)

Zero fees and instantaneous transfer make RaiBlocks extremely attractive for exchange of value, in many senses outperforming Bitcoin at its original intended purpose. This crypto has seen an explosion in price and exposure over the past month, and it may become the network of choice for transferring value within and between crypto exchanges.
Just in the first week of 2018: the CEO of Ledger (makers of the most popular hardware wallet on the market) waived the $50k code review fee to get RaiBlocks on his product, and XRB got listed on Binance and Kucoin, two of the largest altcoin exchanges globally. This is one to watch for 2018. [12]

VeChain (VEN)

Developed as a single answer to the problem of supply-chain logistics, VeChain is knocking on the door of a fast-growing $8 trillion industry. Every shipping container and packaged product in the world requires constant tracking and verification. A smart economy for logistics built on the blockchain promises greater efficiency and lower cost through the entire process flow.
Don’t take my word for it-- VeChain has investment from PwC (5th largest US corporation), Groupe Renault, Kuehne & Nagel (world’s largest freight company), and DIG (China’s largest wine importer). The Chinese government has mandated VeChain to serve as blockchain technology partner to the city of Gui’an, a special economic zone and testbed for China’s smart city of the future. This crypto has some of the strongest commercial partnerships in the industry, and a large active development team.
  1. “Investment” is a misnomer. Cryptos are traded like securities, but grant you no equity (like trading currency).
  2. The weeds for Bitcoin: basic intro (1:36), non-technical explanation (5:24), Bitcoin 101 – Andreas Antonopoulos (23:51).
  3. It is impossible to double-spend or create a fake transaction, as each ledger is confirmed against every other ledger.
  4. Some utility token blockchains use DAG networks or similar non-linear networks which don’t require mining.
  5. In practice, these are giant warehouses full of specialized computers constantly processing transactions. Miners locate to the cheapest electricity source, and the bulk of mining currently occurs in China.
  6. Centralized second-layer exchange websites have been hacked, but the core technology is untouched.
  7. This effect has been termed "bitcoinization".
  8. The Ethereum roadmap shows moving from a Proof of Work (PoW) to Proof of Stake (PoS) consensus model.
  9. At $2.62 per XRP token, Ripple already commands a $100B market cap.
  10. After a January 2017 update.
  11. Monero uses ring signatures while Zcash uses ZK-SNARKs to create anonymity. Both have pros and cons.
  12. Note: all signs point to this crypto being renamed “Nano” in the coming weeks: nano.co.

Major Exchanges
In finance, an exchange is a forum or platform for trading commodities, derivatives, securities or other financial instruments. The principle concern of an exchange is to allow trading between parties to take place in a fair and legally compliant manner, as well as to ensure that pricing information for any instrument traded on the exchange is reliable and coherently delivered to exchange participants. In the cryptocurrency space exchanges are online platforms that allow users to trade cryptocurrencies or digital currencies for fiat money or other cryptocurrencies. They can be centralized exchanges such a Binance, or decentralized exchanges such as IDEX. Most cryptocurrency exchanges allow users to trade different crypto assets with BTC or ETH after having already exchanged fiat currency for one of those cryptocurrencies. Coinbase and Kraken are the main avenue for fiat money to enter into the cryptocurrency ecosystem.
Function and History
Crypto exchanges can be market-makers that take bid/ask spreads as a commission on the transaction for facilitating the trade, or more often charge a small percentage fee for operating the forum in which the trade was made. Most crypto exchanges operate outside of Western countries, enabling them to avoid stringent financial regulations and the potential for costly and lengthy legal proceedings. These entities will often maintain bank accounts in multiple jurisdictions, allowing the exchange to accept fiat currency and process transactions from customers all over the globe.
The concept of a digital asset exchange has been around since the late 2000s and the following initial attempts at running digital asset exchanges foreshadows the trouble involved in attempting to disrupt the operation of the fiat currency baking system. The trading of digital or electronic assets predate Bitcoin’s creation by several years, with the first electronic trading entities running afoul of the Australian Securities and Investments Commission (ASIC) in late 2004. Companies such as Goldex, SydneyGoldSales, and Ozzigold, shut down voluntarily after ASIC found that they were operating without an Australian Financial Services License. E-Gold, which exchanged fiat USD for grams of precious metals in digital form, was possibly the first digital currency exchange as we know it, allowing users to make instant transfers to the accounts of other E-Gold members. At its peak in 2006 E-Gold processed $2 billion worth of transactions and boasted a user base of over 5 million people.
Popular Exchanges
Here we will give a brief overview of the features and operational history of the more popular and higher volume exchanges because these are the platforms to which newer traders will be exposed. These exchanges are recommended to use because they are the industry standard and they inspire the most confidence.
Bitfinex
Owned and operated by iFinex Inc, the cryptocurrency trading platform Bitfinex was the largest Bitcoin exchange on the planet until late 2017. Headquartered in Hong Kong and based in the US Virgin Island, Bitfinex was one of the first exchanges to offer leveraged trading (“Margin trading allows a trader to open a position with leverage. For example — we opened a margin position with 2X leverage. Our base assets had increased by 10%. Our position yielded 20% because of the 2X leverage. Standard trades are traded with leverage of 1:1”) and also pioneered the use of the somewhat controversial, so-called “stable coin” Tether (USDT).
Binance
Binance is an international multi-language cryptocurrency exchange that rose from the mid-rank of cryptocurrency exchanges to become the market dominating behemoth we see today. At the height of the late 2017/early 2018 bull run, Binance was adding around 2 million new users per week! The exchange had to temporarily disallow new registrations because its servers simply could not keep up with that volume of business. After the temporary ban on new users was lifted the exchange added 240,000 new accounts within two hours.
Have you ever thought whats the role of the cypto exchanges? The answer is simple! There are several different types of exchanges that cater to different needs within the ecosystem, but their functions can be described by one or more of the following: To allow users to convert fiat currency into cryptocurrency. To trade BTC or ETH for alt coins. To facilitate the setting of prices for all crypto assets through an auction market mechanism. Simply put, you can either mine cryptocurrencies or purchase them, and seeing as the mining process requires the purchase of expensive mining equipment, Cryptocurrency exchanges can be loosely grouped into one of the 3 following exchange types, each with a slightly different role or combination of roles.
Have you ever thought about what are the types of Crypto exchanges?
  1. Traditional Cryptocurrency Exchange: These are the type that most closely mimic traditional stock exchanges where buyers and sellers trade at the current market price of whichever asset they want, with the exchange acting as the intermediary and charging a small fee for facilitating the trade. Kraken and GDAX are examples of this kind of cryptocurrency exchange. Fully peer-to-peer exchanges that operate without a middleman include EtherDelta, and IDEX, which are also examples of decentralized exchanges.
  2. Cryptocurrency Brokers: These are website or app based exchanges that act like a Travelex or other bureau-de-change. They allow customers to buy or sell crypto assets at a price set by the broker (usually market price plus a small premium). Coinbase is an example of this kind of exchange.
  3. Direct Trading Platform: These platforms offer direct peer-to-peer trading between buyers and sellers, but don’t use an exchange platform in doing so. These types of exchanges do not use a set market rate; rather, sellers set their own rates. This is a highly risky form of trading, from which new users should shy away.
To understand how an exchange functions we need only look as far as a traditional stock exchange. Most all the features of a cryptocurrency exchange are analogous to features of trading on a traditional stock exchange. In the simplest terms, the exchanges fulfil their role as the main marketplace for crypto assets of all kinds by catering to buyers or sellers. These are some definitions for the basic functions and features to know: Market Orders: Orders that are executed instantly at the current market price. Limit Order: This is an order that will only be executed if and when the price has risen to or dropped to that price specified by the trader and is also within the specified period of time. Transaction fees: Exchanges will charge transactions fees, usually levied on both the buyer and the seller, but sometimes only the seller is charged a fee. Fees vary on different exchanges though the norm is usually below 0.75%. Transfer charges: The exchange is in effect acting as a sort of escrow agent, to ensure there is no foul play, so it might also charge a small fee when you want to withdraw cryptocurrency to your own wallet.
Regulatory Environment and Evolution
Cryptocurrency has come a long way since the closing down of the Silk Road darknet market. The idea of crypto currency being primarily for criminals, has largely been seen as totally inaccurate and outdated. In this section we focus on the developing regulations surrounding the cryptocurrency asset class by region, and we also look at what the future may hold.
The United States of America
A coherent uniform approach at Federal or State level has yet to be implemented in the United States. The Financial Crimes Enforcement Network published guidelines as early as 2013 suggesting that BTC and other cryptos may fall under the label of “money transmitters” and thus would be required to take part in the same Anti-money Laundering (AML) and Know your Client (KYC) procedures as other money service businesses. At the state level, Texas applies its existing finance laws. And New York has instituted an entirely new licensing system.
The European Union
The EU’s approach to cryptocurrency has generally been far more accommodating overall than the United States, partly due to the adaptable nature of pre-existing laws governing electronic money that predated the creation of Bitcoin. As with the USA, the EU’s main fear is money laundering and criminality. The European Central Bank (ECB) categorized BTC as a “convertible decentralized currency” and advised all central banks in the EU to refrain from trading any cryptocurrencies until the proper regulatory framework was put in place. A task force was then set up by the European Parliament in order to prevent and investigate any potential money laundering that was making use of the new technology.
Likely future regulations for cryptocurrency traders within the European Union and North America will probably consist of the following proposals: The initiation of full KYC procedures so that users cannot remain fully anonymous, in order to prevent tax evasion and curtail money laundering. Caps on payments that can be made in cryptocurrency, similar to caps on traditional cash transactions. A set of rules governing tax obligations regarding cryptocurrencies Regulation by the ECB of any companies that offer exchanges between cryptocurrencies and fiat currencies It is less likely for other countries to follow the Chinese approach and completely ban certain aspects of cryptocurrency trading. It is widely considered more progressive and wiser to allow the technology to grow within a balanced accommodative regulatory framework that takes all interests and factors into consideration. It is probable that the most severe form of regulation will be the formation of new governmental bodies specifically to form laws and exercise regulatory control over the cryptocurrency space. But perhaps that is easier said than done. It may, in certain cases, be incredibly difficult to implement particular regulations due to the anonymous and decentralized nature of crypto.
Behavior of Cryptocurrency Investors by Demographic
Due to the fact that cryptocurrency has its roots firmly planted in the cryptography community, the vast majority of early adopters are representative of that group. In this section we cover the basic structure of the cryptocurrency market cycle and the makeup of the community at large, as well as the reasons behind different trading decisions.
The Cryptocurrency Market Cycle
Bitcoin leads the bull rally. FOMO (Fear of missing out) occurs, the price surge is a constant topic of mainstream news, business programs cover the story, and social media is abuzz with cryptocurrency chatter. Bitcoin reaches new All Timehigh (ATH) Market euphoria is fueled with even more hype and the cycle is in full force. There is a constant stream of news articles and commentary on the meteoric, seemingly unstoppable rise of Bitcoin. Bitcoin’s price “stabilizes”, In the 2017 bull run this was at or around $14,000. A number of solid, large market cap altcoins rise along with Bitcoin; ETH & LTC leading the altcoins at this time. FOMO comes into play, as the new ATH in market cap is reached by pumping of a huge number of alt coins.
Top altcoins “somewhat” stabilize, after reaching new all-time highs. The frenzy continues with crypto success stories, notable figures and famous people in the news. A majority of lesser known cryptocurrencies follow along on the upward momentum. Newcomers are drawn deeper into crypto and sign up for exchanges other than the main entry points like Coinbase and Kraken. In 2017 this saw Binance inundated with new registrations. Some of the cheapest coins are subject to massive pumping, such as Tron TRX which saw a rise in market cap from $150 million at the start of December 2017 to a peak of $16 billion! At this stage, even dead coins or known scams will get pumped. The price of the majority of cryptocurrencies stabilize, and some begin to retract. When the hype is subsiding after a huge crypto bull run, it is a massive sell signal. Traditional investors will begin to give interviews about how people need to be careful putting money into such a highly volatile asset class. Massive violent correction begins and the market starts to collapse. BTC begins to fall consistently on a daily basis, wiping out the insane gains of many medium to small cap cryptos with it. Panic selling sweeps through the market. Depression sets in, both in the markets, and in the minds of individual investors who failed to take profits, or heed the signs of imminent collapse. The price stagnation can last for months, or even years.
The Influence of Age upon Trading
Did you know? Cryptocurrencies have been called “stocks for millennials” According to a survey conducted by the Global Blockchain Business Council, only 5% of the American public own any bitcoin, but of those that do, an overwhelming majority of 71% are men, 58% of them are between the ages of 18 and 35, and over half of them are minorities. The same survey gauged public attitude toward the high risk/high return nature of cryptocurrency, in comparison to more secure guaranteed small percentage gains offered by government bonds or stocks, and found that 30% would rather invest $1,000 in crypto. Over 42% of millennials were aware of cryptocurrencies as opposed to only 15% of those ages 65 and over. In George M. Korniotis and Alok Kumar’s study into the effects of aging on portfolio management and the quality of decisions made by older investors, they found “that older and experienced investors are more likely to follow “rules of thumb” that reflect greater investment knowledge. However, older investors are less effective in applying their investment knowledge and exhibit worse investment skill, especially if they are less educated and earn lower income.”
Geographic Influence upon Trading
One of the main drivers of the apparent seasonal ebb and flow of cryptocurrency prices is the tax situation in the various territories that have the highest concentrations of cryptocurrency holders. Every year we see an overall market pull back beginning in mid to late January, with a recovery beginning usually after April. This is because “Tax Season” is roughly the same across Europe and the United States, with the deadline for Income tax returns being April 15th in the United States, and the tax year officially ending the UK on the 6th of April. All capital gains must be declared before the window closes or an American trader will face the powerful and long arm of the IRS with the consequent legal proceedings and possible jail time. Capital gains taxes around the world vary from jurisdiction to jurisdiction but there are often incentives for cryptocurrency holders to refrain from trading for over a year to qualify their profits as long term gain when they finally sell. In the US and Australia, for example, capital gains are reduced if you bought cryptocurrency for investment purposes and held it for over a year. In Germany if crypto assets are held for over a year then the gains derived from their sale are not taxed. Advantages like this apply to individual tax returns, on a case by case basis, and it is up to the investor to keep up to date with the tax codes of the territory in which they reside.
2013 Bull run vs 2017 Bull run price Analysis
In late 2016 cryptocurrency traders were faced with the task of distinguishing between the beginnings of a genuine bull run and what might colorfully be called a “dead cat bounce” (in traditional market terminology). Stagnation had gripped the market since the pull-back of early 2014. The meteoric rise of Bitcoin’s price in 2013 peaked with a price of $1,100 in November 2013, after a year of fantastic news on the adoption front with both Microsoft and PayPal offering BTC payment options. It is easy to look at a line going up on a chart and speak after the fact, but at the time, it is exceeding difficult to say whether the cat is actually climbing up the wall, or just bouncing off the ground. Here, we will discuss the factors that gave savvy investors clues as to why the 2017 bull run was going to outstrip the 2013 rally. Hopefully this will help give insight into how to differentiate between the signs of a small price increase and the start of a full scale bull run. Most importantly, Volume was far higher in 2017. As we can see in the graphic below, the 2017 volume far exceeds the volume of BTC trading during the 2013 price increase. The stranglehold MtGox held on trading made a huge bull run very difficult and unlikely.
Fraud & Immoral Activity in the Private Market
Ponzi Schemes Cryptocurrency Ponzi schemes will be covered in greater detail in Lesson 7, but we need to get a quick overview of the main features of Ponzi schemes and how to spot them at this point in our discussion. Here are some key indicators of a Ponzi scheme, both in cryptocurrencies and traditional investments: A guaranteed promise of high returns with little risk. Consistentflow of returns regardless of market conditions. Investments that have not been registered with the Securities and Exchange Commission (SEC). Investment strategies that are a secret, or described as too complex. Clients not allowed to view official paperwork for their investment. Clients have difficulties trying to get their money back. The initial members of the scheme, most likely unbeknownst to the later investors, are paid their “dividends” or “profits” with new investor cash. The most famous modern-day example of a Ponzi scheme in the traditional world, is Bernie Madoff’s $100 billion fraudulent enterprise, officially titled Bernard L. Madoff Investment Securities LLC. And in the crypto world, BitConnect is the most infamous case of an entirely fraudulent project which boasted a market cap of $2 billion at its peak.
What are the Exchange Hacks?
The history of cryptocurrency is littered with examples of hacked exchanges, some of them so severe that the operation had to be wound up forever. As we have already discussed, incredibly tech savvy and intelligent computer hackers led by Alexander Vinnik stole 850000 BTC from the MtGox exchange over a period from 2012–2014 resulting in the collapse of the exchange and a near-crippling hammer blow to the emerging asset class that is still being felt to this day. The BitGrail exchange suffered a similar style of attack in late 2017 and early 2018, in which Nano (XRB) was stolen that was at one point was worth almost $195 million. Even Bitfinex, one of the most famous and prestigious exchanges, has suffered a hack in 2016 where $72 million worth of BTC was stolen directly from customer accounts.
Hardware Wallet Scam Case Study
In late 2017, an unfortunate character on Reddit, going by the name of “moody rocket” relayed his story of an intricate scam in which his newly acquired hardware wallet was compromised, and his $34,000 life savings were stolen. He bought a second hand Nano ledger into which the scammers own recover seed had already been inserted. He began using the ledger without knowing that the default seed being used was not a randomly assigned seed. After a few weeks the scammer struck, and withdrew all the poor HODLer’s XRP, Dash and Litecoin into their own wallet (likely through a few intermediary wallets to lessen the very slim chances of being identified).
Hardware Wallet Scam Case Study Social Media Fraud
Many gullible and hapless twitter users have fallen victim to the recent phenomenon of scammers using a combination of convincing fake celebrity twitter profiles and numerous amounts of bots to swindle them of ETH or BTC. The scammers would set up a profile with a near identical handle to a famous figure in the tech sphere, such as Vitalik Buterin or Elon Musk. And then in the tweet, immediately following a genuine message, follow up with a variation of “Bonus give away for the next 100 lucky people, send me 0.1 ETH and I will send you 1 ETH back”, followed by the scammers ether wallet address. The next 20 or so responses will be so-called sockpuppet bots, thanking the fake account for their generosity. Thus, the pot is baited and the scammers can expect to receive potentially hundreds of donations of 0.1 Ether into their wallet. Many twitter users with a large follower base such as Vitalik Buterin have taken to adding “Not giving away ETH” to their username to save careless users from being scammed.
Market Manipulation
It also must be recognized that market manipulation is taking place in cryptocurrency. For those with the financial means i.e. whales, there are many ways in which to control the market in a totally immoral and underhanded way for your own profit. It is especially easy to manipulate cryptos that have a very low trading volume. The manipulator places large buy orders or sell walls to discourage price action in one way or the other. Insider trading is also a significant problem in cryptocurrency, as we saw with the example of blatant insider trading when Bitcoin Cash was listed on Coinbase.
Examples of ICO Fraudulent Company Behavior
In the past 2 years an astronomical amount of money has been lost in fraudulent Initial Coin Offerings. The utmost care and attention must be employed before you invest. We will cover this area in greater detail with a whole lesson devoted to the topic. However, at this point, it is useful to look at the main instances of ICO fraud. Among recent instances of fraudulent ICOs resulting in exit scams, 2 of the most infamous are the Benebit and PlexCoin ICOs which raised $4 million for the former and $15 million for the latter. Perhaps the most brazen and damaging ICO scam of all time was the Vietnamese Pincoin ICO operation, where $660million was raised from 32,000 investors before the scammer disappeared with the funds. In case of smaller ICO “exit scamming” there is usually zero chance of the scammers being found. Investors must just take the hit. We will cover these as well as others in Lesson 7 “Scam Projects”.
Signposts of Fraudulent Actors
The following factors are considered red flags when investigating a certain project or ICO, and all of them should be considered when deciding whether or not you want to invest. Whitepaper is a buzzword Salad: If the whitepaper is nothing more than a collection of buzzwords with little clarity of purpose and not much discussion of the tech involved, it is overwhelmingly likely you are reading a scam whitepaper.
Signposts of Fraudulent Actors §2
No Code Repository: With the vast majority of cryptocurrency projects employing open source code, your due diligence investigation should start at GitHub or Sourceforge. If the project has no entries, or nothing but cloned code, you should avoid it at all costs. Anonymous Team: If the team members are hard to find, or if you see they are exaggerating or lying about their experience, you should steer clear. And do not forget, in addition to taking proper precautions when investing in ICOs, you must always make sure that you are visiting authentic web pages, especially for web wallets. If, for example, you are on a spoof MyEtherWallet web page you could divulge your private key without realizing it and have your entire portfolio of Ether and ERC-20 tokens cleaned out.
Methods to Avoid falling Victim
Avoiding scammers and the traps they set for you is all about asking yourself the right questions, starting with: Is there a need for a Blockchain solution for the particular problem that a particular ICO is attempting to solve? The existing solution may be less costly, less time consuming, and more effective than the proposals of a team attempting to fill up their soft cap in an ICO. The following quote from Mihai Ivascu, the CEO of Modex, should be kept in mind every time you are grading an ICO’s chances of success: “I’m pretty sure that 95% of ICOswill not last, and many will go bankrupt. ….. not everything needs to be decentralized and put on an open source ledger.”
Methods to Avoid falling Victim §2 Do I Trust These People with My Money, or Not?
If you continue to feel uneasy about investing in the project, more due diligence is needed. The developers must be qualified and competent enough to complete the objectives that they have set out in the whitepaper.
Is this too good to be true?
All victims of the well-known social media scams using fake profiles of Vitalik Buterin, or Bitconnect investors for that matter, should have asked themselves this simple question, and their investment would have been saved. In the case of Bitconnect, huge guaranteed gains proportional to the amount of people you can get to sign up was a blatant pyramid scheme, obviously too good to be true. The same goes for Fake Vitalik’s offer of 1 ether in exchange for 0.1 ETH.
Selling Cryptocurrencies, Several reasons for selling with the appropriate actions to take:
If you are selling to buy into an ICO, or maybe believe Ether is a safer currency to hold for a certain period of time, it is likely you will want to make use of the Ether pair and receive Ether in return. Obviously if the ICO is on the NEO or WANchain blockchain for example, you will use the appropriate pair. -Trading to buy into another promising project that is listing on the exchange on which you are selling (or you think the exchange will experience a large amount of volume and become a larger exchange), you may want to trade your cryptocurrency for that exchange token. -If you believe that BTC stands a good chance of experiencing a bull run then using the BTC trading pair is the suitable choice. -If you believe that the market is about to experience a correction but you do not want to take your gains out of the market yet, selling for Tether or “tethering up” is the best play. This allows you to keep your locked-in profits on the exchange, unaffected by the price movements in the cryptocurrency markets,so that you can buy back in at the most profitable moment. -If you wish to “cash out” i.e. sell your cryptocurrency for fiat currency and have those funds in your bank account, the best pair to use is ETH or BTC because you will likely have to transfer to an exchange like Kraken or Coinbase to convert them into fiat. If the exchange offers Litecoin or Bitcoin Cash pairs it could be a good idea to use these for their fast transaction time and low fees.
Selling Cryptocurrencies
Knowing when and how to sell, as well as strategies to inflate the value of your trade before sale, are important skills as a trader of any product or financial instrument. If you are satisfied that the sale itself of the particular amount of a token or coin you are trading away is the right one, then you must decide at what price you are going to sell. Exchanges exercise their own discretion as to which trading “pairs” they will offer, but the most common ones are BTC, ETH, BNB for Binance, BIX for Bibox etc., and sometimes Tether (USDT) or NEO. As a trader, you decide which particular cryptocurrency to exchange depending on your reason for making that specific trade at that time.
Methods of Sale
Market sell/Limit sell on exchange: A limit sell is an order placed on an exchange to sell as soon as (also specifically only if and when) the price you specified has been hit within the time limit you select. A market order executes the sale immediately at the best possible price offered by the market at that exact time. OTC (or Over the Counter) selling refers to sale of securities or cryptocurrencies in any method without using an exchange to intermediate the trade and set the price. The most common way of conducting sales in this manner is through LocalBitcoins.com. This method of cryptocurrency selling is far riskier than using an exchange, for obvious reasons.
The influence and value of your Trade
There are a number of strategies you can use to appreciate the value of your trade and thus increase the Bitcoin or Ether value of your portfolio. It is important to disassociate yourself from the dollar value of your portfolio early on in your cryptocurrency trading career simply because the crypto market is so volatile you will end up pulling your hair out in frustration following the real dollar money value of your holdings. Once your funds have been converted into BTC and ETH they are completely in the crypto sphere. (Some crypto investors find it more appropriate to monitor the value of their portfolio in satoshi or gwei.) Certainly not limited to, but especially good for beginners, the most reliable way to increase your trading profits, and thus the overall value and health of your portfolio, is to buy into promising projects, hold them for 6 months to a year, and then reevaluate. This is called Long term holding and is the tactic that served Bitcoin HODLers quite well, from 2013 to the present day. Obviously, if something comes to light about the project that indicates a lengthy set back is likely, it is often better to cut your losses and sell. You are better off starting over and researching other projects. Also, you should set initial Price Points at which you first take out your original investment, and then later, at which you take out all your profits and exit the project. That should be after you believe the potential for growth has been exhausted for that particular project.
Another method of increasing the value of your trades is ICO flipping. This is the exact opposite of long term holding. This is a technique in which you aim for fast profits taking advantage of initial enthusiasm in the market that may double or triple the value of ICO projects when they first come to market. This method requires some experience using smaller exchanges like IDEX, on which project tokens can be bought and sold before listing on mainstream exchanges. “Tethering up” means to exchange tokens or coins for the USDT stable coin, the value of which is tethered to the US Dollar. If you learn, or know how to use, technical analysis, it is possible to predict when a market retreatment is likely by looking at the price movements of BTC. If you decide a market pull back is likely, you can tether up and maintain the dollar value of your portfolio in tether while other tokens and coins decrease in value. The you wait for an opportune moment to reenter the market.
Market Behavior in Different Time Periods
The main descriptors used for overall market sentiment are “Bull Market” and “Bear Market”. The former describes a market where people are buying on optimism. The latter describes a market where people are selling on pessimism. Fun (or maybe not) fact: The California grizzly bear was brought to extinction by the love of bear baiting as a sport in the mid 1800s. Bears were highly sought after for their intrinsic fighting qualities, and were forced into fighting bulls as Sunday morning entertainment for Californians. What has this got to do with trading and financial markets? The downward swipe of the bear’s paws gives a “Bear market” its name and the upward thrust of a Bull’s horns give the “Bull Market” its name. Most unfortunately for traders, the bear won over 80% of the bouts. During a Bull market, optimism can sometimes grow to be seemingly boundless, volume is rising, and prices are ascending. It can be a good idea to sell or rebalance your portfolio at such a time, especially if you have a particularly large position in one holding or another. This is especially applicable if you need to sell a large amount of a relatively low-volume holding, because you can then do so without dragging the price down by the large size of your own sell order.

[uncensored-r/CryptoCurrency] ChainLink - Rank 97 with no competitors. Undervalued Gem?

The following post by lamps92 is being replicated because some comments within the post(but not the post itself) have been openly removed.
The original post can be found(in censored form) at this link:
np.reddit.com/ CryptoCurrency/comments/7oqv4x
The original post's content was as follows:
What Does ChainLink Do?
In a nutshell, ChainLink aims to solve the connectivity problem, a key limiting factor for smart contract usability, and whilst it's an ERC-20 token it will not be limited to just the Ethereum blockchain.
What makes $LINK so special? Well, it's the first decentralized oracle network; allowing anyone to securely provide smart contracts with access to key external data, off-chain payments and any other API capabilities. Anyone who has a data feed, useful off-chain service such as local payments, or any other API, can now provide them directly to smart contracts in exchange for LINK tokens.
Partnerships
I will keep this brief, as you can see a full list of current and potential partnerships on https://www.reddit.com/LINKTradecomments/7mob78/list_of_chainlinks_partnershipsprojects_using/
But the main ones to look at are
  • Zeppelin OS
  • Town Crier
  • Request Network
  • SWIFT (we know SmartContract, the company behind ChainLink, are working with SWIFT on improving the efficiency of their bond payments, but nothing official regarding LINK & SWIFT yet).
The Pros
ChainLink has steadily been gaining traction ever since its downfall after the 4chan/reddit SIBOS hypetrain crash (post September). It's remained around the 90-100 rank mark and has yet to really "moon".
  • One of the strongest and most technical whitepapers out in the space atm (https://link.smartcontract.com/whitepaper)
  • Team has been working on this for 3 years and initial testnet is due to be released in Q1
  • Zero competition and first mover advantage even if there was (other oracles are currently centralized)
  • Etherscan shows that soon 95% of all available circulating LINK will be consolidated into less than 15,000 wallets and that continues to shrink as more people try to chase pumps, they're being shaken into stronger hands. As soon as Sergey's saved up LINK is finally handed over to institutions we'll see the price jump by increments of dollars and it'll be way too for most people by then (https://etherscan.io/token/0x514910771af9ca656af840dff83e8264ecf986ca)
  • Team is actively hiring more developers and a head of marketing
  • Only on one major exchange, so price likely to increase when listed on further exchanges
The Cons
  • Team is focused on development rather than shilling (take TRON for example) so lack of news/tweets to get normies on board (can be taken as a pro as you're still considered early)
  • The 4chan meme token
  • GitHub is private whilst the team work on moving from RoR to GO for Q1 Intitial Testnet release.
  • Not all team members listed on the website
So what makes ChainLink valuable?
(Taken from a comment on https://www.reddit.com/CryptoCurrency/comments/7nwis4/why_i_believe_chainlink_link_is_the_most/)
Most importantly, LINK can (and will be) used for data request penalty payments to ensure that node operators provide the requested data. Penalty payments are LINK tokens that are required to be held in escrow by the smart contract. They are paid to the smart contract creator in the event any of the node operators do not meet the required data requests as stated in the smart contract. This provides an incentive for smart contract creators to trust node operators, knowing that they have a form of financial insurance (the penalty payment) in the event a node (or nodes) submit bad data.
For information that will trigger high value smart contracts, smart contract owners will want to require a proportionate amount of link to be held in escrow as penalty payments by the node operators. When link is tied up for penalty payments, it is released over the life of the contract. For example, let’s say party A wants an API snapshot sent every day for 30 days. If the penalty payment for the contract is 300 LINK (per node operator), then each node operator will have 10 LINK released to them at the end of each day – receiving the full 300 LINK at the end of the 30 days if they successfully performed the data request the smart contract asked for. Now imagine the smart contract creator wanted 10 node operators. That means 3000 LINK is taken off the market immediately, and 100 of that 3000 is released each day from the smart contract to the individual node operators (10 each per operator, assuming they provided the requested data). A cycle will be created where more and more smart contracts will make requests and node operators will be limited only by the availability of their LINK tokens to be used for penalty payments.
Add it all together and you have a singular payment method for a desired network (the most secure external data oracle), lots of supply constantly locked up to have enough link for signaling purposes (the reputation boost for a node operator), financial insurance for smart contract creators (penalty payments) for increasingly valuable triggering data in a wide variety of smart contracts, and a network poised for growth as more adapters are built and more API’s become available so that dapps can thrive on any blockchain network. Yes LINk is an ERC20 token, but it is blockchain agnostic and the adapter network can continue to grow.
LINK can also be staked!
LINK staking is another big thing that will do wonders for Chainlink's valuation. Turns out Chainlink oracles can be made into pools, similar to mining pools on bitcoin and ethereum where multiple people come and put their LINKs together to run a more secure oracle node and distribute the profits fairly between each other. This will be huge as it will effectively allow you to stake your LINK tokens and earn more of them passively without doing anything. One such pool in development is LinkPool (http://www.linkpool.io/).
Where do i buy and store LINK?
You can currently buy LINK at the following exchanges;
  • Binance
  • Coss
  • EtherDelta
  • IDEX
  • GATE
  • Okex
As an ERC-20 token, you can store LINK on your ledger or MEW wallets.
Here is a well written guide on how to purchase LINK https://www.reddit.com/LINKTradecomments/7gglfv/how_to_buy_link_chainlink_token/

4 Sub-$10 Million Market Cap Coins Worth Keeping An Eye On

1. Spectrecoin ($XSPEC) – $8.6 Million

What is Spectrecoin?

Utilizing a “range of proven cryptographic techniques” to achieve anonymous, untraceable, and un-linkable transactions, Spectrecoin is a secure Proof-of-Stake cryptocurrency enabling rapid P2P transactions and network privacy. Specifically, Spectrecoin is pulling out all the stops in order to protect user identity through their integration of:
At its core, Spectre’s dual coin system sanctions four fundamental types of privacy and anonymity transactions, XSPEC > XSPEC, XSPEC > SPECTRE, SPECTRE > SPECTRE, and SPECTRE > XSPEC, providing a plethora of transaction options for every type of user.
And finally, if you’re looking for the TLDR (too long, didn’t read), Spectrecoin notes the best way to understand SPECTRE is to think of Bitcoin + Proof-of-Stake.v3 + anonymous transactions (similar to Monero) + Tor (for IP obfuscation).

Why You Should Keep an Eye On XSPEC

Unlike several other privacy coins which merely provide a Tor proxy—availing users to potential malicious exit nodes—Spectrecoin is fully integrated with Tor, a reliable and tested network providing one of the largest pools of IP addresses for confidentiality and untraceability.
Coupled with staking, set at a 5% minimum per year, Spectrecoin offers a unique proposition (the only one in blockchain) for users looking to earn rewards while remaining anonymous by staking anonymous coins while generating more, fresh anonymous ones.
Furthermore, for those looking for affirmation of Spectrecoin’s commitment to anonymity, not even the developers know each other’s real names—something that would have made walking away from a lacklustre ICO (which only raised 16 BTC at $600/700 per BTC) all too easy.
Spectre has emphasized organic growth without an excessive and aggressive marketing push, opting instead for a working product and timely improvements to meet the ever-changing privacy arms race. And, with their funding gap set around £19,000, users can take solace in knowing the project isn’t an outright cash grab asking for millions to further tenuous goodwill—like far too many projects in the cryptosphere.
At time of writing, XSPEC is listed on CoinMarketcap at US$0.41 or 5,970 Satoshis.
Finally, if you’re wondering how Spectrecoin stacks up to other privacy coins, such as Monero, PIVX, and Zcash, check out this comparison chart.

2. FundRequest ($FND) – $1 Million

What is FundRequest?

In an age where open source software is an integral component for institutional, government, and nonprofit function and growth, there unfortunately remains a hindering factor—a cohesive, transparent, and styled request and transaction flow.
Cue FundRequest, a decentralized marketplace for open source collaboration and catalyst for global open source sharing and circulation, empowering organizations, government, and other entities to:
Need to brush up on what exactly ‘open source’ means? The Open Source Initiative describes the concept of ‘open source’ as a tool which “enables a development method for software that harnesses the power of distributed peer review and transparency of process.”
For example, a requesting organization (referred to as the funder) will allot set funds—stored in a smart contract (i.e., escrow)—in order to tackle an open source issue, which is then picked up and solved by a developer (the solver). In order to eliminate malicious behavior, FundRequest requires solvers to “have skin in the game,” by staking proportional valued funds, all released and claimed once the issue is solved.
Simply put, FundRequest is the go-to facilitating and incentivization platform (similar to Airbnb and Uber) for funding, claiming, and rewarding open source commits and contributions, leading to an enriched and more collaborative open source ecosystem.

Why You Should Keep an Eye On FND

With an estimated US$60 billion-plus in savings per year for organizations and institutions, thanks to open-source software and technology adoption, FundRequest is set to act as the glue which connects all dispersed and integral parts and actors. Traditional software, prohibitive costs, and predatory vendor practices are proving not to be conducive towards maximal technological growth and development, as most people and organizations just simply can’t afford or maintain it.
Plus, with a clear push by both private and public sectors to leverage community-based software for development and distribution over the last decade, it’s expanding at rapid pace. In 2018, it’s approximated over 50% of European and North American companies utilize open source software for “crucial applications,” along with over 50% of American government organizations.
This is no small industry.
GitHub alone boasts over 24 million users (more than 8 times their user base five years ago), and it’s estimated that in the EU and United States combined, there’s over 160 million persons working as freelancers and independent contractors in what’s known as the “gig economy.” And that’s just the tip of the iceberg, with over 60% of online gig economy workers accounted for in Asia.
As of August 1st, FND’s price sits at right around US$0.03 or 472 Satoshis.
Finally, for open source projects and ERC-20 token projects looking to increase development capacity, consider checking out FundRequest for potential partnerships. Already in their short tenure, FundRequest has partnered with:

3. COSS ($COSS) – $7.7 Million

What is COSS?

Redefining convenience, simplicity, and compatibility, and short for the “Crypto One-Stop Solution’ exchange and platform, COSS is the native token and liquidity attraction tool of the Singapore-based exchange, boasting some of the most popular altcoins on the market while enabling users to receive weekly payouts in “dust” for all traded tokens.
Specifically, COSS is looking to provide more than just a simple, fast, and secure cryptocurrency trading exchange—they’re building a borderless, digital economical system to bring cryptocurrencies to the masses via:
Ultimately, COSS is looking to shake up the cryptocurrency exchange ecosystem through improved user experience, heightened product and feature functions, and a comprehensive foundation for employers, startups, companies, and traders to build towards a more accessible and mainstream cooperative blockchain community.

Why You Should Keep an Eye on COSS

With the rapid and gargantuan successes enjoyed by both Kucoin and Binance in 2018, crypto exchanges employing user-friendly token incentivization models are becoming a go-to for users looking to generate passive income while diversifying their crypto portfolio.
However, unlike other cryptocurrency exchanges which have lowered their daily fee splits to nominal amounts, COSS has stayed true towards user rewards, keeping their daily percentage at 50%—paying out the respective dividends via a decentralized autonomous organization, ultimately guaranteeing an immutable percentage.
In order to stay competitive in the present-day blockchain ecosystem, COSS’s whitepaper notes a minimum of 3-5 new features implemented per quarter. In the past several months, below are just several of their most notable achievements:
And, if you’re looking to know what COSS’s endgame here is, their goal is to shift completely towards a decentralized autonomous organization (DAO) in the future, where governance and decision making is outlined in code and run by a peer-to-peer network.
Currently, COSS’s price is listed at US$0.06 or 935 Satoshis on Coinmarketcap.
Finally, if you’re curious about COSS’s fee sharing, check out the COSS fee share calculator, which provides an accurate picture of your monthly exchange fee earnings relative to the amount of COSS owned. One Reddit user recently posted, and provided a screenshot, showing the COSS annual dividends to be at nearly 10% per year.

4. Lamden ($TAU) – $6.9 Million

What is Lamden?

Named after the Sherpa language word meaning “to guide,” Lamden is staying true to its name by easing the creation and deployment of dapps and custom blockchains.
At its core, Lamden is providing a suite of developer tools mimicking “modern development processes in such tech stacks as Node.js or Python.” Simply put, Lamden is supplying the building blocks for experienced and amateur blockchain developers alike, enabling organizations and enterprise to skirt the energy and time costs of hiring and training expensive blockchain developers—ultimately speeding up efficiency and reducing overhead costs.
Lamden is broken up into three fundamental sections, which all are in furtherance of project depth and the deployment of hyperfast blockchains for developers to not only experiment with, but test and deploy across other blockchain systems and platforms:
Furthermore, Lamden supports the Ethereum network and Bitcoin-based blockchains at present, and boasts zero transaction fees and free chain-to-chain payments in exchange for chain allocation a specific amount of bandwidth for confirming payment channel transactions—meaning that its users are able to transact for free as a result of corporate entities bearing the network load and processing.

Why You Should Keep an Eye On TAU

Having released their ‘Cilantro’ testnet alpha in February 2018, Lamden has since hit the ground running, rolling out their first version of Clove soon after and tackling the necessary tune-ups and improvements in preparation of their mainnet launch in Q4 2018. Lamden’s mainnet is set to utilize a unique combination of Delegated Proof-of-Stake (DPoS) and the BFT Protocol, and will scale to process nearly 10,000 transactions per second.
Moreover, in April 2018, Lamden announced the creation of LamDEX, their own decentralized cryptocurrency exchange and platform, where users will be able to stake their TAU—the native token of the Lamden platform—to act as a market maker, allowing for a cohesive back and forth across the TAU pair at prices faintly above and below market cost, ultimately generating rewards.
With a rather daunting and tedious task ahead for anyone looking to utilize and incorporate existing smart contracts—which involves the manual searching for such on GitHub (a general repository website)—Lamden is truly adding value to blockchain and application development through their smart contract repository. Unlike GitHub, Lamden supports dependencies, versioning, and security, all essential elements for a quality package manager.
Doing so adds not only convenience, but practicality to smart contract packages and implementation, and stands to save enterprise and organizations both exorbitant developer costs and time.
If you’d like to learn more about Lamden’s developer tool suite, check out this complete overview from their blog.
At the time of writing, Lamden’s price according to Coinmarketcap is US$0.04 or 699 Satoshis.
To get a better picture of Lamden and their blockchain development tools ecosystem, check out this explanatory YouTube video from their channel.
Final Thoughts
Risk is inevitable when investing in crypto and blockchain projects. However, as long as you are cognizantly defining parameters for absorbing such risk, then diversifying your portfolio with smaller capped projects can be an effective way to realize value.
Whether you’re looking for a user-friendly exchange to purchase crypto directly with fiat from (and earn dividends for loyalty) or wanting to execute anonymous and secure transactions with a P2P coin, the aforementioned projects are all bringing value to the crypto sphere through their overhaul of ineffective traditional mechanisms and institutions.
Make sure to stay calm and collected during this bear market, associate yourself with quality projects that you think are bringing actual value to severely flawed industries, and remember, having a little gamble in you never hurts (as long as it’s properly accounted for).
