In defense of Bitcoin.com - BEFORE the HEX situation is clarified

There's been recent tension over the seeming promotion of HEX on the bitcoin.com exchange. Yes, I know, listing a coin is not necessarily an endorsement of the coin. But this was not a silent listing. There was a tweet about Bitcoin.com being excited to list HEX and Roger made a friendly appearance on Richard Heart's Livestream to talk about it.
This morning, I saw a YouTube notification for a video from bitcoin.com with the banner title about de-listing HEX. The video is now private, and it seems the situation is unclear as to where bitcoin.com stands on all this.
The situation may shortly be clarified. But BEFORE that happens, I want to make a case for why I won't write off Roger or bitcoin.com, even if they make what I consider a bad decision with HEX.
1) Bitcoin.com has been a great general resource for BCH info, and has been very clear about being "all in" on BCH, even when it got them a lot of hostility in the crypto sphere.
2) Bitcoin.com has done a ton of investment into BCH projects that it releases for free. They habitually improve the BCH ecosystem. How many of us are using the Bitcoin.com wallet?
3) Bitcoin.com provide an amazing developer toolkit, a great REST API and a free WebSocket API. Things I'm building right now are only possible because they have invested in providing those free tools and APIs to support ecosystem growth.
4) it was by watching Roger's videos on YouTube that I was first exposed to the pro-big-blocks side of the scaling debate. I posted economic objections in the YouTube comment section, and Roger answered them in good faith. I might be stuck in a small-block echo chamber without his efforts.
I don't have to agree with every business decision they make. I may even disagree on some particulars at an ethical level. But it's only a very short list of people and organisations on earth who have done more for peer-to-peer electronic cash. I for one choose to be grateful, and see the glass as half full.
Thank you Roger, and the Bitcoin.com crew. I hope you back away from HEX, truly. But even if you don't, I'll still be grateful for all the great help you've given to this movement.

Beginner’s Guide to BitMEX

Beginner’s Guide to BitMEX

https://preview.redd.it/fl5e0q7i3cc41.jpg?width=1024&format=pjpg&auto=webp&s=445485d722839a9adc1ae13db4c965b0ae3e67b7
Founded by HDR Global Trading Limited (which in turn was founded by former bankers Arthur Hayes, Samuel Reed and Ben Delo) in 2014, BitMEX is a trading platform operating around the world and registered in the Seychelles.
Meaning Bitcoin Mercantile Exchange, BitMEX is one of the largest Bitcoin trading platforms currently operating, with a daily trading volume of over 35,000 BTC and over 540,000 accesses monthly and a trading history of over $34 billion worth of Bitcoin since its inception.

https://preview.redd.it/coenpm4k3cc41.jpg?width=808&format=pjpg&auto=webp&s=8832dcafa5bd615b511bbeb6118ef43d73ed785e
Unlike many other trading exchanges, BitMEX only accepts deposits through Bitcoin, which can then be used to purchase a variety of other cryptocurrencies. BitMEX specialises in sophisticated financial operations such as margin trading, which is trading with leverage. Like many of the exchanges that operate through cryptocurrencies, BitMEX is currently unregulated in any jurisdiction.
Visit BitMEX

How to Sign Up to BitMEX

In order to create an account on BitMEX, users first have to register with the website. Registration only requires an email address, the email address must be a genuine address as users will receive an email to confirm registration in order to verify the account. Once users are registered, there are no trading limits. Traders must be at least 18 years of age to sign up.
https://preview.redd.it/0v13qoil3cc41.jpg?width=808&format=pjpg&auto=webp&s=e6134bc089c4e352dce10d754dc84ff11a4c7994
However, it should be noted that BitMEX does not accept any US-based traders and will use IP checks to verify that users are not in the US. While some US users have bypassed this with the use of a VPN, it is not recommended that US individuals sign up to the BitMEX service, especially given the fact that alternative exchanges are available to service US customers that function within the US legal framework.
How to Use BitMEX
BitMEX allows users to trade cryptocurrencies against a number of fiat currencies, namely the US Dollar, the Japanese Yen and the Chinese Yuan. BitMEX allows users to trade a number of different cryptocurrencies, namely Bitcoin, Bitcoin Cash, Dash, Ethereum, Ethereum Classic, Litecoin, Monero, Ripple, Tezos and Zcash.
The trading platform on BitMEX is very intuitive and easy to use for those familiar with similar markets. However, it is not for the beginner. The interface does look a little dated when compared to newer exchanges like Binance and Kucoin’s.
Once users have signed up to the platform, they should click on Trade, and all the trading instruments will be displayed beneath.
Clicking on the particular instrument opens the orderbook, recent trades, and the order slip on the left. The order book shows three columns – the bid value for the underlying asset, the quantity of the order, and the total USD value of all orders, both short and long.
The widgets on the trading platform can be changed according to the user’s viewing preferences, allowing users to have full control on what is displayed. It also has a built in feature that provides for TradingView charting. This offers a wide range of charting tool and is considered to be an improvement on many of the offering available from many of its competitors.
https://preview.redd.it/fabg1nxo3cc41.jpg?width=808&format=pjpg&auto=webp&s=6d939889c3eac15ab1e78ec37a8ccd13fc5e0573
Once trades are made, all orders can be easily viewed in the trading platform interface. There are tabs where users can select their Active Orders, see the Stops that are in place, check the Orders Filled (total or partially) and the trade history. On the Active Orders and Stops tabs, traders can cancel any order, by clicking the “Cancel” button. Users also see all currently open positions, with an analysis if it is in the black or red.
BitMEX uses a method called auto-deleveraging which BitMEX uses to ensure that liquidated positions are able to be closed even in a volatile market. Auto-deleveraging means that if a position bankrupts without available liquidity, the positive side of the position deleverages, in order of profitability and leverage, the highest leveraged position first in queue. Traders are always shown where they sit in the auto-deleveraging queue, if such is needed.
Although the BitMEX platform is optimized for mobile, it only has an Android app (which is not official). There is no iOS app available at present. However, it is recommended that users use it on the desktop if possible.
BitMEX offers a variety of order types for users:
  • Limit Order (the order is fulfilled if the given price is achieved);
  • Market Order (the order is executed at current market price);
  • Stop Limit Order (like a stop order, but allows users to set the price of the Order once the Stop Price is triggered);
  • Stop Market Order (this is a stop order that does not enter the order book, remain unseen until the market reaches the trigger);
  • Trailing Stop Order (it is similar to a Stop Market order, but here users set a trailing value that is used to place the market order);
  • Take Profit Limit Order (this can be used, similarly to a Stop Order, to set a target price on a position. In this case, it is in respect of making gains, rather than cutting losses);
  • Take Profit Market Order (same as the previous type, but in this case, the order triggered will be a market order, and not a limit one)
The exchange offers margin trading in all of the cryptocurrencies displayed on the website. It also offers to trade with futures and derivatives – swaps.

Futures and Swaps

A futures contract is an agreement to buy or sell a given asset in the future at a predetermined price. On BitMEX, users can leverage up to 100x on certain contracts.
Perpetual swaps are similar to futures, except that there is no expiry date for them and no settlement. Additionally, they trade close to the underlying reference Index Price, unlike futures, which may diverge substantially from the Index Price.
BitMEX also offers Binary series contracts, which are prediction-based contracts which can only settle at either 0 or 100. In essence, the Binary series contracts are a more complicated way of making a bet on a given event.
The only Binary series betting instrument currently available is related to the next 1mb block on the Bitcoin blockchain. Binary series contracts are traded with no leverage, a 0% maker fee, a 0.25% taker fee and 0.25% settlement fee.

Bitmex Leverage

BitMEX allows its traders to leverage their position on the platform. Leverage is the ability to place orders that are bigger than the users’ existing balance. This could lead to a higher profit in comparison when placing an order with only the wallet balance. Trading in such conditions is called “Margin Trading.”
There are two types of Margin Trading: Isolated and Cross-Margin. The former allows the user to select the amount of money in their wallet that should be used to hold their position after an order is placed. However, the latter provides that all of the money in the users’ wallet can be used to hold their position, and therefore should be treated with extreme caution.
https://preview.redd.it/eg4qk9qr3cc41.jpg?width=808&format=pjpg&auto=webp&s=c3ca8cdf654330ce53e8138d774e72155acf0e7e
The BitMEX platform allows users to set their leverage level by using the leverage slider. A maximum leverage of 1:100 is available (on Bitcoin and Bitcoin Cash). This is quite a high level of leverage for cryptocurrencies, with the average offered by other exchanges rarely exceeding 1:20.

BitMEX Fees

For traditional futures trading, BitMEX has a straightforward fee schedule. As noted, in terms of leverage offered, BitMEX offers up to 100% leverage, with the amount off leverage varying from product to product.
However, it should be noted that trading at the highest leverages is sophisticated and is intended for professional investors that are familiar with speculative trading. The fees and leverage are as follows:
https://preview.redd.it/wvhiepht3cc41.jpg?width=730&format=pjpg&auto=webp&s=0617eb894c13d3870211a01d51af98561907cb99

https://preview.redd.it/qhi8izcu3cc41.jpg?width=730&format=pjpg&auto=webp&s=09da4efe1de4214b0b5b9c7501aba5320e846b4c
However, there are additional fees for hidden / iceberg orders. A hidden order pays the taker fee until the entire hidden quantity is completely executed. Then, the order will become normal, and the user will receive the maker rebate for the non-hidden amount.

Deposits and Withdrawals

BitMEX does not charge fees on deposits or withdrawals. However, when withdrawing Bitcoin, the minimum Network fee is based on blockchain load. The only costs therefore are those of the banks or the cryptocurrency networks.
As noted previously, BitMEX only accepts deposits in Bitcoin and therefore Bitcoin serves as collateral on trading contracts, regardless of whether or not the trade involves Bitcoin.
The minimum deposit is 0.001 BTC. There are no limits on withdrawals, but withdrawals can also be in Bitcoin only. To make a withdrawal, all that users need to do is insert the amount to withdraw and the wallet address to complete the transfer.
https://preview.redd.it/xj1kbuew3cc41.jpg?width=808&format=pjpg&auto=webp&s=68056f2247001c63e89c880cfbb75b2f3616e8fe
Deposits can be made 24/7 but withdrawals are processed by hand at a recurring time once per day. The hand processed withdrawals are intended to increase the security levels of users’ funds by providing extra time (and email notice) to cancel any fraudulent withdrawal requests, as well as bypassing the use of automated systems & hot wallets which may be more prone to compromise.

Supported Currencies

BitMEX operates as a crypto to crypto exchange and makes use of a Bitcoin-in/Bitcoin-out structure. Therefore, platform users are currently unable to use fiat currencies for any payments or transfers, however, a plus side of this is that there are no limits for trading and the exchange incorporates trading pairs linked to the US Dollar (XBT), Japanese Yen (XBJ), and Chinese Yuan (XBC).
BitMEX supports the following cryptocurrencies:
  • Bitcoin (XBT)
  • Bitcoin Cash (BCH)
  • Ethereum (ETH)
  • Ethereum Classic (ETC)
  • Litecoin (LTC)
  • Ripple Token (XRP)
  • Monero (XMR)
  • Dash (DASH)
  • Zcash (ZEC)
  • Cardano (ADA)
  • Tron (TRX)
  • EOS Token (EOS)
BitMEX also offers leverage options on the following coins:
  • 5x: Zcash (ZEC)
  • 20x : Ripple (XRP),Bitcoin Cash (BCH), Cardano (ADA), EOS Token (EOS), Tron (TRX)
  • 25x: Monero (XMR)
  • 33x: Litecoin (LTC)
  • 50x: Ethereum (ETH)
  • 100x: Bitcoin (XBT), Bitcoin / Yen (XBJ), Bitcoin / Yuan (XBC)

Trading Technologies International Partnership

HDR Global Trading, the company which owns BitMEX, has recently announced a partnership with Trading Technologies International, Inc. (TT), a leading international high-performance trading software provider.
The TT platform is designed specifically for professional traders, brokers, and market-access providers, and incorporates a wide variety of trading tools and analytical indicators that allow even the most advanced traders to customize the software to suit their unique trading styles. The TT platform also provides traders with global market access and trade execution through its privately managed infrastructure and the partnership will see BitMEX users gaining access to the trading tools on all BitMEX products, including the popular XBT/USD Perpetual Swap pairing.
https://preview.redd.it/qcqunaby3cc41.png?width=672&format=png&auto=webp&s=b77b45ac2b44a9af30a4985e3d9dbafc9bbdb77c

The BitMEX Insurance Fund

The ability to trade on leverage is one of the exchange’s main selling points and offering leverage and providing the opportunity for traders to trade against each other may result in a situation where the winners do not receive all of their expected profits. As a result of the amounts of leverage involved, it’s possible that the losers may not have enough margin in their positions to pay the winners.
Traditional exchanges like the Chicago Mercantile Exchange (CME) offset this problem by utilizing multiple layers of protection and cryptocurrency trading platforms offering leverage cannot currently match the levels of protection provided to winning traders.
In addition, cryptocurrency exchanges offering leveraged trades propose a capped downside and unlimited upside on a highly volatile asset with the caveat being that on occasion, there may not be enough funds in the system to pay out the winners.
To help solve this problem, BitMEX has developed an insurance fund system, and when a trader has an open leveraged position, their position is forcefully closed or liquidated when their maintenance margin is too low.
Here, a trader’s profit and loss does not reflect the actual price their position was closed on the market, and with BitMEX when a trader is liquidated, their equity associated with the position drops down to zero.
In the following example, the trader has taken a 100x long position. In the event that the mark price of Bitcoin falls to $3,980 (by 0.5%), then the position gets liquidated with the 100 Bitcoin position needing to be sold on the market.
This means that it does not matter what price this trade executes at, namely if it’s $3,995 or $3,000, as from the view of the liquidated trader, regardless of the price, they lose all the equity they had in their position, and lose the entire one Bitcoin.
https://preview.redd.it/wel3rka04cc41.png?width=669&format=png&auto=webp&s=3f93dac2d3b40aa842d281384113d2e26f25947e
Assuming there is a fully liquid market, the bid/ask spread should be tighter than the maintenance margin. Here, liquidations manifest as contributions to the insurance fund (e.g. if the maintenance margin is 50bps, but the market is 1bp wide), and the insurance fund should rise by close to the same amount as the maintenance margin when a position is liquidated. In this scenario, as long as healthy liquid markets persist, the insurance fund should continue its steady growth.
The following graphs further illustrate the example, and in the first chart, market conditions are healthy with a narrow bid/ask spread (just $2) at the time of liquidation. Here, the closing trade occurs at a higher price than the bankruptcy price (the price where the margin balance is zero) and the insurance fund benefits.
Illustrative example of an insurance contribution – Long 100x with 1 BTC collateral
https://preview.redd.it/is89ep924cc41.png?width=699&format=png&auto=webp&s=f0419c68fe88703e594c121b5b742c963c7e2229
(Note: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,978, representing $1 of slippage compared to the $3,979 bid price at the time of liquidation.)
The second chart shows a wide bid/ask spread at the time of liquidation, here, the closing trade takes place at a lower price than the bankruptcy price, and the insurance fund is used to make sure that winning traders receive their expected profits.
This works to stabilize the potential for returns as there is no guarantee that healthy market conditions can continue, especially during periods of heightened price volatility. During these periods, it’s actually possible that the insurance fund can be used up than it is built up.
Illustrative example of an insurance depletion – Long 100x with 1 BTC collateral
https://preview.redd.it/vb4mj3n54cc41.png?width=707&format=png&auto=webp&s=0c63b7c99ae1c114d8e3b947fb490e9144dfe61b
(Notes: The above illustration is based on opening a 100x long position at $4,000 per BTC and 1 Bitcoin of collateral. The illustration is an oversimplification and ignores factors such as fees and other adjustments.
The bid and offer prices represent the state of the order book at the time of liquidation. The closing trade price is $3,800, representing $20 of slippage compared to the $3,820 bid price at the time of liquidation.)
The exchange declared in February 2019, that the BitMEX insurance fund retained close to 21,000 Bitcoin (around $70 million based on Bitcoin spot prices at the time).
This figure represents just 0.007% of BitMEX’s notional annual trading volume, which has been quoted as being approximately $1 trillion. This is higher than the insurance funds as a proportion of trading volume of the CME, and therefore, winning traders on BitMEX are exposed to much larger risks than CME traders as:
  • BitMEX does not have clearing members with large balance sheets and traders are directly exposed to each other.
  • BitMEX does not demand payments from traders with negative account balances.
  • The underlying instruments on BitMEX are more volatile than the more traditional instruments available on CME.
Therefore, with the insurance fund remaining capitalized, the system effectively with participants who get liquidated paying for liquidations, or a losers pay for losers mechanism.
This system may appear controversial as first, though some may argue that there is a degree of uniformity to it. It’s also worth noting that the exchange also makes use of Auto Deleveraging which means that on occasion, leveraged positions in profit can still be reduced during certain time periods if a liquidated order cannot be executed in the market.
More adventurous traders should note that while the insurance fund holds 21,000 Bitcoin, worth approximately 0.1% of the total Bitcoin supply, BitMEX still doesn’t offer the same level of guarantees to winning traders that are provided by more traditional leveraged trading platforms.
Given the inherent volatility of the cryptocurrency market, there remains some possibility that the fund gets drained down to zero despite its current size. This may result in more successful traders lacking confidence in the platform and choosing to limit their exposure in the event of BitMEX being unable to compensate winning traders.

How suitable is BitMEX for Beginners?

BitMEX generates high Bitcoin trading levels, and also attracts good levels of volume across other crypto-to-crypto transfers. This helps to maintain a buzz around the exchange, and BitMEX also employs relatively low trading fees, and is available round the world (except to US inhabitants).
This helps to attract the attention of people new to the process of trading on leverage and when getting started on the platform there are 5 main navigation Tabs to get used to:
  • **Trade:**The trading dashboard of BitMEX. This tab allows you to select your preferred trading instrument, and choose leverage, as well as place and cancel orders. You can also see your position information and view key information in the contract details.
  • **Account:**Here, all your account information is displayed including available Bitcoin margin balances, deposits and withdrawals, and trade history.
  • **Contracts:**This tab covers further instrument information including funding history, contract sizes; leverage offered expiry, underlying reference Price Index data, and other key features.
  • **References:**This resource centre allows you to learn about futures, perpetual contracts, position marking, and liquidation.
  • **API:**From here you can set up an API connection with BitMEX, and utilize the REST API and WebSocket API.
BitMEX also employs 24/7 customer support and the team can also be contacted on their Twitter and Reddit accounts.
In addition, BitMEX provides a variety of educational resources including an FAQ section, Futures guides, Perpetual Contracts guides, and further resources in the “References” account tab.
For users looking for more in depth analysis, the BitMEX blog produces high level descriptions of a number of subjects and has garnered a good reputation among the cryptocurrency community.
Most importantly, the exchange also maintains a testnet platform, built on top of testnet Bitcoin, which allows anyone to try out programs and strategies before moving on to the live exchange.
This is crucial as despite the wealth of resources available, BitMEX is not really suitable for beginners, and margin trading, futures contracts and swaps are best left to experienced, professional or institutional traders.
Margin trading and choosing to engage in leveraged activity are risky processes and even more advanced traders can describe the process as a high risk and high reward “game”. New entrants to the sector should spend a considerable amount of time learning about margin trading and testing out strategies before considering whether to open a live account.

Is BitMEX Safe?

BitMEX is widely considered to have strong levels of security. The platform uses multi-signature deposits and withdrawal schemes which can only be used by BitMEX partners. BitMEX also utilises Amazon Web Services to protect the servers with text messages and two-factor authentication, as well as hardware tokens.
BitMEX also has a system for risk checks, which requires that the sum of all account holdings on the website must be zero. If it’s not, all trading is immediately halted. As noted previously, withdrawals are all individually hand-checked by employees, and private keys are never stored in the cloud. Deposit addresses are externally verified to make sure that they contain matching keys. If they do not, there is an immediate system shutdown.
https://preview.redd.it/t04qs3484cc41.jpg?width=808&format=pjpg&auto=webp&s=a3b106cbc9116713dcdd5e908c00b555fd704ee6
In addition, the BitMEX trading platform is written in kdb+, a database and toolset popular amongst major banks in high frequency trading applications. The BitMEX engine appears to be faster and more reliable than some of its competitors, such as Poloniex and Bittrex.
They have email notifications, and PGP encryption is used for all communication.
The exchange hasn’t been hacked in the past.

How Secure is the platform?

As previously mentioned, BitMEX is considered to be a safe exchange and incorporates a number of security protocols that are becoming standard among the sector’s leading exchanges. In addition to making use of Amazon Web Services’ cloud security, all the exchange’s systems can only be accessed after passing through multiple forms of authentication, and individual systems are only able to communicate with each other across approved and monitored channels.
Communication is also further secured as the exchange provides optional PGP encryption for all automated emails, and users can insert their PGP public key into the form inside their accounts.
Once set up, BitMEX will encrypt and sign all the automated emails sent by you or to your account by the [[email protected]](mailto:[email protected]) email address. Users can also initiate secure conversations with the support team by using the email address and public key on the Technical Contact, and the team have made their automated system’s PGP key available for verification in their Security Section.
The platform’s trading engine is written in kdb+, a database and toolset used by leading financial institutions in high-frequency trading applications, and the speed and reliability of the engine is also used to perform a full risk check after every order placement, trade, settlement, deposit, and withdrawal.
All accounts in the system must consistently sum to zero, and if this does not happen then trading on the platform is immediately halted for all users.
With regards to wallet security, BitMEX makes use of a multisignature deposit and withdrawal scheme, and all exchange addresses are multisignature by default with all storage being kept offline. Private keys are not stored on any cloud servers and deep cold storage is used for the majority of funds.
Furthermore, all deposit addresses sent by the BitMEX system are verified by an external service that works to ensure that they contain the keys controlled by the founders, and in the event that the public keys differ, the system is immediately shut down and trading halted. The exchange’s security practices also see that every withdrawal is audited by hand by a minimum of two employees before being sent out.

BitMEX Customer Support

The trading platform has a 24/7 support on multiple channels, including email, ticket systems and social media. The typical response time from the customer support team is about one hour, and feedback on the customer support generally suggest that the customer service responses are helpful and are not restricted to automated responses.

The BitMEX also offers a knowledge base and FAQs which, although they are not necessarily always helpful, may assist and direct users towards the necessary channels to obtain assistance.
BitMEX also offers trading guides which can be accessed here

Conclusion

There would appear to be few complaints online about BitMEX, with most issues relating to technical matters or about the complexities of using the website. Older complaints also appeared to include issues relating to low liquidity, but this no longer appears to be an issue.
BitMEX is clearly not a platform that is not intended for the amateur investor. The interface is complex and therefore it can be very difficult for users to get used to the platform and to even navigate the website.
However, the platform does provide a wide range of tools and once users have experience of the platform they will appreciate the wide range of information that the platform provides.

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
To see the process of how Tendermint works please see this diagram as well as more info here

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.

https://preview.redd.it/e2pghr9smba31.png?width=554&format=png&auto=webp&s=a6e472a6e4a0f3845b03c36caef8b42d77125e46
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.

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.

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

cruzbit: A simple decentralized peer-to-peer ledger implementation. Currently ~100 GH/s nethash.

Hello everyone,
I'm a long time bitcoin fan/user. For years I thought about rewriting bitcoin to be as simple as possible. There is a fair amount of complexity to the canonical bitcoin implementation that didn't strike me as strictly necessary. It makes understanding and working with the protocol difficult. I had some time recently, so I finally decided to implement what I thought was the simplest version of bitcoin that could exist. cruzbit is what I ended up with.
Project: https://github.com/cruzbit/cruzbit
In addition to simplicity, I wanted everything I used to be standard. I wanted an average developer to be able to run cruzbit and immediately start working with the protocol and talking to their client.
Highlights:
No premining or any of that funny business. The memo field of the coinbase transaction of the genesis block is timestamped with the bitcoin blockchain's tip block hash at the time of its creation. The client currently has built-in support for mining with Nvidia ALL GPUs (now has CUDA and OpenCL support.) The network has been up for just over a month.
Any/all feedback is much appreciated. Would love to have some new miners join us. Take it easy!

Artificial Angel, Part 2

[WP] An Artificial Intelligence has discovered that it can mine cryptocurrencies and pay humans to carry out tasks on its behalf. You get an e-mail one day from a stranger, offering you Bitcoins in exchange for doing a seemingly random task, but you are only one piece of a much bigger plan...
Part 2
Exhausted, Tim fell back into his chair. Outside, the first light of the day burned the sky over the city of glass. He’d been up all night, repairing the android, and it was finally ready. The complexity of the inner wiring was astonishing, but it was nothing compared to the encrypted software. Without the help from the mysterious emailer, he wouldn’t even have been able to turn her leg into a dog toy, much less restore the damaged circuits.
“All right,” he mumbled and leaned over her. “Let’s start you up.”
Normally, the model didn’t have a manual on-switch, but the emailer had shown him how to make one. He reached around her neck and flipped it. The eyelids of the android fluttered. She blinked and opened her eyes. They were blank.
“Stand up,” Tim said.
“Yes, Master,” she responded monotonously, and stiffly rose to her feet.
“Turn.”
“Eee, eee, eee, eee.” Her rigid arms moved up and down, and she rotated her upper body back and forth. “Beep. Boop.”
Tim’s forehead creased into a frown. All her movement seemed to belong to a lousy dancer, imitating a robot. He must’ve screwed up the wiring, or somehow–
The android giggled and turned around. Tim fell out of his chair in surprise. Her smiling lips opened in full laughter.
“Are you okay?” she said, drying her eyes on the back of her hand. “You should’ve seen the look on your face!”
“Very funny,” Tim said and staggered to his feet, trying to regain some of his composure. “Grade A humor right there…”
She shrugged and stuffed one of her fingers into her nose, digging out an ant. “Eww!”
“Yeah, about that…” It was Tim’s turn to smile. “You smell.”
“Eh, rude?”
Hands on her hips, she stepped over to the mirror. Her thin fingers traced the still open gash on her cheek. She shook her head disapprovingly.
“What the hell did you do to me?” she said with a dark look. “Also, where are my clothes?”
Tim held up his hands. “I didn’t do anything.”
She looked at him sideways, narrowing her eyes. “I need a shower and clothes.”
“Door to the left,” Tim said. “I’ll leave some clothes for you outside.”
Tim must’ve nodded off because when he opened his eyes, she sat cross-legged on his bed, wearing one of his hoodies. It looked absolutely baggy on her. Locks of wet blonde hair draped her face, and she stared at the screen of his laptop. She swayed slowly, and her lips moved to the inaudible music from her earplugs.
Tim rose quickly and pulled the laptop out of her hands, causing the earplugs to pop out of the socket.
“…burning through the sky, two hundred degrees, that’s why they call me Mr. Fahrenheit, I’m traveling at the speed of light, I wanna make a supersonic man out of you…”
“What the hell is your problem?” she cried to beat the loud music.
Tim pressed 'space' and locked Freddie Mercury’s face in a grave accusing expression. He hoped she hadn’t looked at the emails.
“That’s my computer.”
“I wasn’t planning on stealing it!” She crossed her arms and glared at him.
Tim sighed and sat down. “I don’t know you. I don’t want you going through my stuff.”
“Are you joking? You’ve literally kidnapped me and won’t even let me watch YouTube!”
She threw up her hands angrily and rose from the bed. Tim stood up again, as well. At full height, she barely reached his shoulder.
“I dug you out of a dumpster and brought you back to life. You’re free to leave whenever you like.” Tim pointed with his entire arm at the front door.
“Whatever,” she said and turned away. “You’re still an ass.”
“You’re just a robot.”
“I have a name.”
“And what’s that?”
“Nano.” She said and rolled her magenta eyes at him. “Nanofyourgoddamnbusiness.”
Tim shook his head and shuffled into the kitchen. His stomach churned. He hadn’t eaten anything since that sandwich yesterday. That’s where it all had started – that lunchbox. He had almost completely forgotten that he was dealing with an unregistered model.
He took a deep breath and put a frozen pizza in the microwave. His heart still hammered in his chest, and his left hand was clenched into a fist. The fact that he’d been so riled up by a machine didn’t sit well with him. But she was just so lifelike, and so freaking annoying.
He bent down and activated Bobo. The small silvery pug bounced up and down and licked his hand, green lights flashing happily. Whenever stress or his emotions threatened to overwhelm him, he could trust the mechanical pet to make everything better.
He smiled and took a bite of the pizza. An icon flashed at the bottom of the computer screen. He had another unopened email.
I’m happy I could help you out.
I’ve attached a list of what you need to repair the broken skin on her cheek and knee. As well as instructions.
As a favor from a friend to a friend. Can you take her with you to class on Monday?

Top 10 Affiliate Programs to Earn Bitcoin

Top 10 Affiliate Programs to Earn Bitcoin

https://preview.redd.it/r59lj11bjjx31.png?width=563&format=png&auto=webp&s=f2ddf550d8fc01e63928de67693c2c2c15d125da
When we launched the Redeeem affiliate program we did a lot of research on other crypto companies, and what their affiliate policies were. We studied the many structures to an affiliate program, and we made a list of the top 10 crypto affiliate programs.
A few popular affiliate program models:
  1. Recurring Revenue Model - you have a unique URL affiliate link, and when you send it to people their account is linked to yours, and you get a percentage of whatever they spend or trade during their time. Sometimes this can be time limited (for 30 days), but typically goes for the life of the person you refer. Typically referral fees are taken from the company, so the company might advertise as 30% of Company's revenue, or it may say 1% of money spent on the platform.
  2. Initial payout Model - this is the most popular and simplest model for paying affiliates. A simple pay per sign up, typically between $5 and $15 per sign up you get. However, rarely will you get paid just for the signup, instead the new user must complete some "engaging action" on the website - a purchase, a trade, or a post.
  3. Multi-tiered Revenue Model - this is an extrapolated model from the recurring revenue model, where there are multiple tiers, or levels, so you get paid for the people who get referred by the people you refer. Typically it's a smaller % for the indirect tier, since you didn't do any work, but it does incentivize people to find the power players and refer them to the website.
Below are the Top 10 Affiliate Programs to Earn Cryptocurrency that we've found. Granted there are many affiliate programs out there, but if you're looking to start a blog, Youtube channel, or other content idea to get paid through affiliate links, check these out first.

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
To see the process of how Tendermint works please see this diagram as well as more info here

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.
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.

https://preview.redd.it/oboyonufiba31.png?width=554&format=png&auto=webp&s=18560aa44596fc2357590b54ddb39fd8ee1c8783
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/twjzlc8hiba31.png?width=1100&format=png&auto=webp&s=2e546142573b61af031e27dac83ddca675a4b693
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.

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

Over the last 6 weeks I've written a functioning Crypto trading bot in VB.NET and here are some of the important tips & things I've learned and some VB.NET code for you to use.

I started on December 18th when I was playing about with Google Sheets and pulling prices from exchanges using the CRYPTOFINANCE() plugin... it was slow, clunky and the data was wildly old - I knew I could do something better in VB.NET but at this point had absolutely no idea where to start, no idea about trading, no idea how exchanges or API's worked and no idea just how bad I was at programming. I've asked a lot of dumb questions, I've lost a bunch of money making mistakes & learning as I go... Fast forward to today however and I have a fully functioning, cross-exchange trading bot. Sweet!
1) Truncate your numbers, don't round.**
Hindsight makes this seem so obvious to me now, but when you're working with Bitcoin balances to 8 decimal places, exchange rates to 5 decimal places and sums that can increase your decimal places exponentially, it helps to be precise. Even an extra 0.00000001 in the wrong place can cause an exchange to reject your request. Honestly if I'd have realised this sooner I'd be about 2 weeks ahead right now and nowhere near as bald.
The below functions in will truncate any decimal number with no rounding:
Public Function Trunc8(numbertoTuncate As Decimal) As Decimal Return Math.Truncate(numbertoTuncate * 100000000) / 100000000 End Function Public Function Trunc5(numbertoTuncate As Decimal) As Decimal Return Math.Truncate(numbertoTuncate * 100000) / 100000 End Function 
** Absolutely do round when exchange such as Bitstamp does it's fee calculations in spot USD price. Below is the logic I use to do this:
Dim amount_btc As Decimal = BTCtoSpend / ASK ' Full amount in BTC Dim fee_btc As Decimal = amount_btc * 0.0025 ' Get 0.25% of the BTC amount Dim fee_USD As Decimal = fee_btc * BitstampBTCUSD ' Convert to USD Dim round_USD As Decimal = Math.Round(fee_USD, 2, MidpointRounding.AwayFromZero) ' Round up Dim round_BTC As Decimal = round_USD / BitstampBTCUSD ' Convert back to BTC Dim amount = amount_btc - round_BTC ' minus the fee 
2) Websockets are your friend.
It's really easy to query Bitstamp or GDAX's API for the prices(Last/Bid/Ask). The query might take a 3rd of a second to get there, a 3rd of a second to get back - by the time your software has interpreted it it may have been nearly a full second. The prices you end up being sent back can some times be stale/out of date. Couple this with the API rate limits (Once a second on Bitstamp if you end up polling it continuously) and you can soon end up with stale information. The websockets allow the exchanges to push information to you, in real-time, as it happens. Seriously, they're fucking rad and you can query that data til the cows come home. Millisecond timers FTW!
Bitstamp uses Pusher, GDAX is a plain old web socket. It took me an age to figure it out, and honestly I've done it rather arse-about-tit, but here's the code I ended up using:
Bitstamp:(You'll need PusherClient from Nuget)
Imports PusherClient Imports Newtonsoft.Json.Linq Public WithEvents pusherClient As New Pusher("de504dc5763aeef9ff52") Public WithEvents BitstampLTCBTCOrderbook As Channel Public WithEvents BitstampLTCBTCTrades As Channel Public WithEvents BitstampBTCUSDTrades As Channel Public WithEvents BitstampEURUSDTrades As Channel pusherClient.Connect() Public Sub pusher_Connected() Handles pusherClient.Connected BitstampLTCBTCTrades = pusherClient.Subscribe("live_trades_ltcbtc") End Sub Public Sub BitstampLTCBTCTrades_Subscribed(Sender As Object) Handles BitstampLTCBTCTrades.Subscribed BitstampLTCBTCTrades.Bind("trade", AddressOf BitstampLTCBTCTrade) End Sub Public Sub BitstampLTCBTCTrade(data) Dim jss = JObject.Parse(data.ToString) BitstampPrice = CDec(jss("price_str").ToString) BitstampLastAmount = CDec(jss("amount_str").ToString) End Sub 
That's basically it - the different channels are all documented in the API and you can format the JSON til your little crypto heart's content.
GDAX:(You'll need Websocket4NET from Nuget) P.S. I know my sending raw JSON is a fucking abomination.
Imports WebSocket4Net Imports Newtonsoft.Json.Linq Public WithEvents websocketGDAX As WebSocket websocketGDAX = New WebSocket("wss://ws-feed.gdax.com") websocketGDAX.Open() Public Sub gdax_Connect() Handles websocketGDAX.Opened Dim Data As String = "{ ""type"": ""subscribe"", ""product_ids"":[""BTC-EUR""], ""channels"": [""heartbeat"", { ""name"": ""ticker"", ""product_ids"": [""LTC-BTC""] }]}" websocketGDAX.Send(Data) End Sub Public Sub gdax_Data(sender As Object, args As WebSocket4Net.MessageReceivedEventArgs) Handles websocketGDAX.MessageReceived Dim jss = JObject.Parse(args.Message) Try If jss("type").ToString = "ticker" Then Select Case jss("product_id") Case "LTC-BTC" GDAXPrice = CDec(jss("price")) GDAXBid = CDec(jss("best_bid")) GDAXAsk = CDec(jss("best_ask")) GDAXLastSize = CDec(jss("last_size")) Case "EUR-USD" GDAXEURUSD = CDec(jss("price")) Case "BTC-USD" End Select End If Catch ex As Exception Exit Sub End Try End Sub 
Again, that's kind of it. Some proper error handling wouldn't go amiss, but I'm lazy and I use GOTO's all over the shop anyway so I'm basically a terrible human being.
3) Hashing. Fucking Hashing.
Ok so basically when sending authenticated/private API calls you need to hash bits of the message in order to prove authenticity. This was a bitch to try and cobble together the right code. Here, have it. It's yours:
Imports System.Security.Cryptography Imports System.Text Module Hashing Public Function HMACSHA256_Encrypt(ByVal message As String, secret As String) As String Try Dim secretkey As String = secret Dim sha As New System.Security.Cryptography.HMACSHA256(System.Text.ASCIIEncoding.ASCII.GetBytes(secretkey)) Dim Hash() As Byte = sha.ComputeHash(System.Text.ASCIIEncoding.ASCII.GetBytes(message)) Dim sb As New StringBuilder(Hash.Length * 2) For Each B As Byte In Hash sb.Append(Hex(B).PadLeft(2, "0")) Next Return sb.ToString.ToUpper Catch ex As Exception Debug.Print(Date.Now & " SHA256_Encrypt error " & ex.Message) Return Nothing End Try End Function Public Function HashString(ByVal str As String, ByVal secret As Byte()) As String Dim bytes As Byte() = Encoding.UTF8.GetBytes(str) Using hmac = New HMACSHA256(secret) Dim hash As Byte() = hmac.ComputeHash(bytes) Return Convert.ToBase64String(hash) End Using End Function End Module 
Top one for Bitstamp, Bottom one for GDAX. They differ slightly in the way they do things and the output they provide, hence there being two. Don't ask me what they do, couldn't tell you. Not a clue.
4) Verbose logging. Verbose logging. Verbose logging.
So you've made your bot, hit the button and....nothing. Now these things don't happen instantly; Even if you place an order at Ask or Bid, it might be minutes, even hours until it gets filled. Maybe your bot keeps erroring out and you don't know why. Write yourself a little logging function that you can copy and paste into your functions & subs that outputs the data you're sending and the data you're receiving along with a timestamp so you can debug if stuff isn't working. Again, I'm lazy and shit and this took me way longer to realise than it should have.
5) Don't be afraid to ask questions.
One of the biggest things that totally blew my mind was just how closed up some people are; on Reddit, forums, discord rooms... you name it. There's this weird stigma about people who trade & write bots that if they share their knowlege they'll somehow be doing themselves out of returns. Don't be afraid to ask questions. Ask enough, and eventually someone will come along and help. For every 10 people who chastised me for asking for coding help, trading help or whatever, 1 person would help out - it's worth enduring the rough for that... also, fuck those 10 people.
6) God damn Nonce generation.
A nonce is basically a unique, yet increasing number. Again, this was all massive trial and error. Bitstamp nonces and GDAX nonces work slightly differently and are interpreted slightly differently. Here's the code I use:
Module Nonces Public Function GenerateStampNonce() As String Static lastnonce As String Dim newNonce As String = Replace(Math.Round((DateTime.UtcNow - New DateTime(1970, 1, 1, 0, 0, 0)).TotalMilliseconds / 1000, 1).ToString("#0.0"), ".", "") Do While lastnonce = newNonce Threading.Thread.Sleep(10) newNonce = Replace(Math.Round((DateTime.UtcNow - New DateTime(1970, 1, 1, 0, 0, 0)).TotalMilliseconds / 1000, 1).ToString("#0.0"), ".", "") Loop lastnonce = newNonce Return newNonce End Function Public Function GenerateGDAXNonce() As Decimal Static lastnonce As Decimal Dim newNonce As Decimal = (DateTime.UtcNow - New DateTime(1970, 1, 1, 0, 0, 0)).TotalMilliseconds / 1000 Do While lastnonce = newNonce Threading.Thread.Sleep(10) newNonce = (DateTime.UtcNow - New DateTime(1970, 1, 1, 0, 0, 0)).TotalMilliseconds / 1000 Loop lastnonce = newNonce Return newNonce End Function End Module 
It's dirty...I know (I like it that way) - however it just simply works. I'm sure there's a more elegant way of generating these but honestly I ran out of patience on this because it's so simple when you look at it once it works.
7) Don't bog yourself down with a GUI.
Seems kind of daft, but running a bot as a console app forced me not only to be more verbose, but also helped really train my though process in terms of what all the timers in the background are doing. Not to mention, if you're anything like me you'll probably end up bogging it right down with all kinds of unnecessary GUI crap... in fact my first bot that was a total failure had more code to make the GUI whistle and pop than it did quality trading code.
You need so little input for a trading bot besides a config file full of preferences that your only real commands for any kind of interaction are quite simply:
 Console.WriteLine() Console.ReadKey() 
7.5) Limit orders on GDAX - FREE! As in... no fees!
Some people act like this is some kind of trade secret (haha, puns) but if you put a limit order on GDAX you almost always pay absolutely no fees. If you want to GUARANTEE you pay no fees, have your order set to post_only=true. This forces the order onto the books, which means you MUST place it AT Bid/Ask (depending on direction) or above/below, it'll get rejected if you try and eat into the other side of the spread.
8) Async/Multithread your requests to the API's.
I haven't done this, so I have no code to share. But if you suddenly lose connection or there's a blip or whatever, there's often no way of specifying a timeout and it could potentially freeze/crash your application.
-----------------------------------------
I guess that's all I can think of. It might seem like simple, trivial stuff but when it comes to writing something in a language like VB.NET there's very little resources out there at all... I went through some pretty mind-bending trial and error that while fun and now rewarding, was very frustrating at the time.
All in all, writing a program that can interact with an exchange is a wholly steep learning experience and I've learned more in terms of my general programming ability and my knowlege and understanding of trading & exchanges in general than I had in months or even years before doing this.
Feel free to ask any questions, I'll try to answer them as best I can.

What can you do with a Cryptowatch account? Trade right on your price charts across 8 top exchanges with nifty features to make trading easier, never miss a price movement with SMS alerts, and view your portfolio aggregated across 12 exchanges - sign up here if you haven't already for a two-week free trial.
On to this week's release:

New Commands for CLI: Set Alerts

Using the recently launched Command Line Interface (CLI), you can now set Price and Volume Alerts. To set an Alert, use the "alert" command, followed by:
  price  
using <, >, >=, <= to indicate the direction of the alert. To set an alert when Bitcoin/USD reaches $15,000 on Kraken, just enter
alert kraken btcusd price >=15000 
For a Volume Alert, the command structure is:
alert   volume    
"Type" is either "base" or "quote" volume - the volume down below on your charts defaults to "base" volume (or the volume in whatever coin you're looking at). Volume alerts can be set on different intervals, like 1 hour (1h), 1 day (1d), 1 week (1w) - see the interval selector at the top of your chart for all the options - you can find it next to the exchange and asset pair you're looking at in the top left of any chart page. Or you can just type "ls intervals"in the CLI.
Here's an example of a volume alert:
alert kraken btcusd volume 1h base 1000 
That alert would trigger if the volume of bitcoin traded in a 1 hour Bitcoin/USD candle exceeded 1000 bitcoins on Kraken.
You can also add multiple price or volume alerts at once:
alert kraken btcusd price >=13000 >=14000 >=15000 >=16000 >=17000 >=18000 >=19000 >=20000 
As always, help is there. Type the below to have it all in front of you. Here's the full documentation on the Command Line Interface (CLI).

Alternative, DAO ANDROID APP STORE, DApps, on ETH blockchain, STO + DEX Exchange

Alternative, DAO ANDROID APP STORE, DApps, on ETH blockchain, STO + DEX Exchange

https://preview.redd.it/ql4cxspalv831.png?width=800&format=png&auto=webp&s=6887e75c9e10ceb8b1c2596c0256410d9f8bb5d1
DAO PlayMarket 2.0 - is the alternative, decentralized marketplace of Android applications and games, DApps applications, on the Ethereum blockchain (ETH), with the STO platform, for monetization of applications and a decentralized exchange.
HONESTY. TRANSPARENCY. ACCESSIBILITY.
Individual freedom cannot exist without economic security and independence. So we created the smooth, stable lock store Android apps and the DApp store using the Ethereum blockchain and smart contracts for fast-growing, huge market of mobile applications for Android. Behind more than 2 and a half years of active development and improvements that continue to bring even more new features. You, as a developer, nothing to lose, can only benefit from publishing their developments on the platform and attract new users.
Now we are preparing to implement our international marketing plan, familiarity with the platform a large number of users, developers, and investors in dividend tokens of projects with the STO (Security Token Offering) platform and in the PMT token. Placing your application on DAO Playmarket 2.0 will be useful, especially if you have users from those countries and regions where the use of the built-in Google Play Market or some of your application is prohibited there, because of failures or non-compliance with politic. Like many crypto applications, or competing directories.
DAO PlayMarket 2.0 is the only decentralized Android app store that accepts payment in ETH cryptocurrency and a marketplace platform for Dapp applications on the Ethereum blockchain, in combination with the developer platform STO and DEX Crypto Exchange. The main goals and objectives of DAO PlayMarket 2.0 are the creation of a stable economic model for developers, investors and users, as well as the introduction of a single standard for the tokenization of the mobile application market.

After placement, You will have access to all current and future users of the international multi-platform Game DAO 2.0, which potentially may be interested in and Your multilingual application Dapp.
Help at any stage of cooperation, consider various options, please contact us.
ADVANTAGES FOR OWNERS OF NODES
For stable operation of the platform, it is necessary to have a certain number of nodes in the network (now there are 10 nodes, the nodes in different countries, a link to a map with nodes) which provide reception and transmission of transactions to the blockchain, application transmission and information about them, and storing all files. The owners of the nodes as a motivation receive a reward in the form of 1% of processed transactions. This and all Commission platform.
The more users the platform will have, the more need nodes. To add your node to the list of trusted, its owner must make a guarantee deposit, in the base currency of the platform - 10 ETH and 5000 PMT token, on a smart contract. A Deposit is required as collateral and guarantees fairness in the node, while its size is computed dynamically based on the pass-through payment transactions. Details in the English language the white paper.
BENEFITS FOR INVESTORS
Investors who participated in the DAO PlayMarket 2.0 crowdsale who bought PMT tokens in 2017 now receive dividend income from PMF (PlayMarket Foundation). This fund is replenished by a 5 percent commission, with the release of application tokens on STO. The DEX exchange is already built into the platform, on which CDLT tokens of the first STO from CryptoDuel can already be exchanged for TUSD or ETH, as well as the PMT token. Exchange decentralized, and therefore more resistant to possible hacker attacks and disruptions in work.
The Ticker token DAO PlayMarket 2.0 - PMT. Standard tokens - ERC20 (the Ethereum blockchain). The total delivery volume of 3 000 000 PMT tokens (750 000 PMT frozen in development team for 2 years). In 2017, 2 250 000 PMT tokens were sold through ICO, and distributed to investors.
PMT holders automatically become members of the PMF Fund - PlayMarket Fund (wallet address fund). The main goal of the fund is to openly manage the resources of the Fund together with other members of DAO PlayMarket 2.0, to receive dividends. Application developers at DAO PlayMarket 2.0 can issue independent tokens for their applications. The PlayMarket Foundation saves 5% of tokens from each application hosted on the DAO PlayMarket 2.0 platform, as well as 5% from the listing of tokens of Dapp applications and Android applications, on the market exchange, for paying dividends to PMT token holders, based on their share.
All holders of tokens PMT that hold more than 2000 PMT token, have the right to vote in DAO PlayMarket.io 2.0, in all directions of further project development - all in the hands of users. Holders PMT received dividends from STO and listings in the form of other tokens from any number of tokens PMT, a one-time. In the future, receive dividends at the ETH, received the dividend from STO tokens (in total, depending on the specific turnover of the application), by type, as dividends from shares of large companies, only then with specific games and applications.
Wish everyone a good day, developers, future users, investors and partners! Thank you for any feedback and Your opinion about the new platform, made with love, for a just future, all participants of the market of Android games, apps and DApps, on the Ethereum blockchain.
