What is USDT?
USDT is a cryptocurrency asset issued on the Bitcoin blockchain via the Omni Layer Protocol. Each USDT unit is backed by a U.S Dollar held in the reserves of the Tether Limited and can be redeemed through the Tether Platform. USDT can be transferred, stored, spent, just like bitcoins or any other cryptocurrency, users can transact and store tethers with any Omni Layer enabled wallet like Ambisafe, Holy Transaction or Omni Wallet.
USDT and other Tether currencies were created to facilitate the transfer of national currencies, to provide users with a stable alternative to Bitcoin and to provide an alternative for exchange and wallet audits which are currently unreliable. USDT provides an alternative to Proof of Solvency methods by introducing a Proof of Reserves Process.
In the Tether Proof of Reserves system, the amount of USDT in circulations can be easily checked on the Bitcoin blockchain via the tools provided at Omnichest.info, while the corresponding total amount of USD held reserves is proved by publishing the bank balance and undergoing periodic audits by professionals.
The amount of USDT in circulation must always correspond to the amount of USD in the bank account used by Tether Limited to receive and send fiat currency to users who purchase/redeem tethers directly on the Tether Platform.
To prove that the amount of USD in the bank account is the same or more than the USDT in circulation, Tether Limited publishes the bank account balance on its website’s Transparency page. Professional auditors will regularly verify, sign, and publish the underlying bank balance and financial transfer statement.

What is Bitcoin?
Bitcoin is a digital asset and a payment system invented by Satoshi Nakamoto who published a related paper in 2008 and released it as open-source software in 2009. The system featured as peer-to-peer; users can transact directly without an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain. The ledger uses bitcoin as its unit of account. The system works without a central repository or single administrator, which has led the U.S. Treasury to categorize bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed. Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value by now.
Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins. Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.
Bitcoin proposes a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they ’ll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.

What is Bitcoin Cash?
Bitcoin Cash was created as an answer to the years-long debate among the Bitcoin community regarding the best way to scale Bitcoin to more users. The simplest solution, and the one adopted by Bitcoin Cash, is to increase the Max Block size Limit parameter of the Bitcoin codebase. While Bitcoin’s block size limit remains at 1 megabyte (allowing for ~250,000 transactions per day), Bitcoin Cash has increased the limit to 8MB, allowing for around two million transactions to be processed per day.
As far as the users of Bitcoin/Bitcoin Cash are concerned there is very little noticeable difference on the frontend when using either currency. The main difference between these coins is the fact that, given equal hash rate, BCH protocol allows for more transactions per second which translates to faster payments and lower fees.
Bitcoin Cash brings sound money to the world, fulfilling the original promise of Bitcoin as “Peer-to-Peer Electronic Cash”. Merchants and users are empowered with low fees and reliable confirmations. The future shines brightly with unrestricted growth, global adoption, permissionless innovation, and decentralized development.
All Bitcoin holders as of block 478558 are also owners of Bitcoin Cash. All are welcome to join the Bitcoin Cash community as we move forward in creating sound money accessible to the whole world.

What is Ethereum?
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. These apps run on a custom built blockchain, an enormously powerful shared global infrastructure that can move value around and represent the ownership of property.
This enables developers to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract) and many other things that have not been invented yet, all without a middle man or counterparty risk. The project was bootstrapped via an ether presale in August 2014 by fans all around the world. It is developed by the Ethereum Foundation, a Swiss nonprofit, with contributions from great minds across the globe.
The intent of Ethereum is to create an alternative protocol for building decentralized applications, providing a different set of tradeoffs that we believe will be very useful for a large class of decentralized applications, with particular emphasis on situations where rapid development time, security for small and rarely used applications, and the ability of different applications to very efficiently interact, are important. Ethereum does this by building what is essentially the ultimate abstract foundational layer: a blockchain with a built-in Turing-complete programming language, allowing anyone to write smart contracts and decentralized applications where they can create their own arbitrary rules for ownership, transaction formats and state transition functions. A bare-bones version of Namecoin can be written in two lines of code, and other protocols like currencies and reputation systems can be built in under twenty. Smart contracts, cryptographic “boxes” that contain value and only unlock it if certain conditions are met, can also be built on top of the platform, with vastly more power than that offered by Bitcoin scripting because of the added powers of Turing-completeness, value-awareness, blockchain-awareness and state.

What is Litecoin?
Litecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Litecoin is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances. Litecoin features faster transaction confirmation times and improved s torage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.
Litecoin was released via an open-source client on GitHub on October 7, 2011 by Charlie Lee, a former Google employee. The Litecoin network went live on October 13, 2011. It was a fork of the Bitcoin Core client, differing primarily by having a decreased block generation time (2.5 minutes), increased maximum number of coins, different hashing algorithm (scrypt, instead of SHA-256), and a slightly modified GUI.
In May 2017, Litecoin became the first of the top-5 (by market cap) cryptocurrencies to adopt Segregated Witness.Later in May of the same year, the first Lightning Network transaction was completed through Litecoin, transferring 0.00000001 LTC from Zürich to San Francisco in under one second. In November 26, 2017, its market capitalization is US$4,600,081,733 at around $85.18 per coin.

What is Bitcoin Gold (BTG)?
Bitcoin Gold is a community-led project to create an experimental hard fork of Bitcoin to a new proof-of-work algorithm. The purpose for doing this is to make Bitcoin mining decentralized again. Satoshi Nakamoto’s idealistic vision of “one CPU one vote” has been superseded by a reality where the manufacture and distribution of mining equipment has become dominated by a very small number of entities, some of whom have engaged in abusive practices against individual miners and the Bitcoin network as a whole. Bitcoin Gold will provide an opportunity for countless new people around the world to participate in the mining process with widely-available consumer hardware that is manufactured and distributed by reputable mainstream corporations. A more decentralized, democratic mining infrastructure is more resilient and more in line with Satoshi’s original vision. Perhaps, if the Bitcoin Gold experiment is judged by the community to be a success, it may one day help build consensus for a proof-of-work hard fork on Bitcoin itself.
Bitcoin Gold decentralizes mining by adopting a PoW algorithm, Equihash, which cannot be run faster on the specialty equipment used for Bitcoin mining (ASIC miners.) This gives ordinary users a fair opportunity to mine with ubiquitous GPUs.
Hard forking Bitcoin’s blockchain fairly and efficiently distributes a new digital asset immediately to people all over the world who have interest in cryptocoins. Other methods, such as creating coins with a new genesis block, concentrate ownership within a small group.
To ensure the safety of the Bitcoin ecosystem, Bitcoin Gold has implemented full replay protection and unique wallet addresses, essential features that protect users and their coins from several kinds of accidents and malicious threats.

What is Ethereum Classic?
Ethereum Classic is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. Ethereum Classic is a continuation of the original Ethereum blockchain – the classic version preserving untampered history; free from external interference and subjective tampering of transactions.
Ethereum Classic is an open-source, public, blockchain-based distributed computing platform featuring smart contract (scripting) functionality. It provides a decentralized Turing-complete virtual machine, the Ethereum Virtual Machine (EVM), which can execute scripts using an international network of public nodes. Ethereum Classic also provides a value token called “classic ether”, which can be transferred between participants, stored in a cryptocurrency wallet and is used to compensate participant nodes for computations performed. The classic ether token is traded on cryptocurrency exchanges under the ticker symbol ETC. Gas, an internal transaction pricing mechanism, is used to prevent spam on the network and allocate resources proportionally to the incentive offered by the request.

What is EOS?
EOS tokens are ERC-20 compatible tokens distributed on the Ethereum blockchain pursuant to a related ERC-20 smart contract (the “EOS Tokens”). EOS featured in powerful infrastructure for decentralized application and token distribution takes place over 341 days.
Traditionally, it is the business that pays for office space, computational power, and other costs required to run the business. The customer buys specific products from the business and the revenue from those product sales is used to cover the business costs of operation. Similarly, no website obligates its visitors to make micropayments for visiting its website to cover hosting costs. Therefore, decentralized applications should not force its customers to pay the blockchain directly for the use of the blockchain.
