BTC (Bitcoin)
Release date: 30.10.2008
Website: https://bitcoin.org/zh_CN/
Product Information:
Bitcoin is a cryptocurrency and digital payment system invented by an unknown programmer or a group of programmers named Satoshi Nakamoto. It was released as an open source software in 2009. It is a peer-to-peer system, and transactions are conducted between users directly, without any intermediary. These transactions are checked by network nodes and recorded in a public distributed ledger called blockchain. Due to the system’s ability to operate without any central body or any single administrator, bitcoin is known to be the first decentralized digital currency. Bitcoin is the reward earned for validating a transaction on the blockchain and can be exchanged for other currencies, products and services.

USDT (Tether)
Release date: 2014
Website: https: //tether.to/
Product Information:
Tether (USDT) is a digital currency released on the bitcoin blockchain under the omni layer protocol, the value of which always corresponds to the value of the U.S dollar. Tether was launched in 2014. The idea was to create a stable cryptocurrency, which could be used as a digital dollar or as a “stablecoin”. Tether is used as a method of hedging (insurance) against the volatility of the market due to its stability. With each USDT token tied to one dollar, storing money in Tether protects it from the usual volatility of the cryptocurrency market. This is why most Bitcoin transactions are conducted in Tether, as it allows for flexible entry and exit of cryptocurrency trade.

ETH (Ethereum)
Release date: 30.07.2015
Website: https://ethereum.org/
Product Information:
Ethereum is a smart contract platform that allows developers to create decentralized applications (Dapps) on their blockchain.
Ethereum is partially supported by the Ethereum Foundation, a non-profit organization that is part of the larger Ethereum ecosystem, along with corporate consortia such as the Ethereum Enterprise Alliance.
Vitalik Bouterin, first conceptualized Ethereum in 2013 with the idea of developing an open source platform blockchain other than Bitcoin (BTC), thus creating smart contracts. On the ethereum blockchain, a smart contract behaves like an autonomous computer program, which is automatically executed under certain conditions. Blockchain allows the launch of smart contract code exactly as it is programmed, not subject to simple, censored, fraudulent, or third-party interference.
Ethereum was launched on July 30, 2015, with 73 million Ether installed in advance.
Mining ethereum is currently based on the proof-of-work (Pow) protocol (like Bitcoin), but in the future it is planned to move to proof-of-stake, proof of ownership. Mining Ethereum occurs when miners use their computational power to solve a mathematical problem (finding unique hash block header metadata). The first miner who successfully solved the problem (finding the hash) then sends a message that the block has been retrieved to the entire Ethereum network so that other nodes can validate it and add it to the blockchain.

Dai (DAI)
Release date: 2017
Website: https://makerdao.com/
Dai (DAI) is a stablecoin linked to the U.S dollar. This is the internal cryptocurrency of the Maker DAO platform, which has another payment device known as MKR. The DAI project addresses the problems associated with linking virtual assets to certain values. The stability of DAI is not only ensured by a rigid peg to the dollar, the coin also serves as a collateral. The developers believe that a coin with collateral tied to a stable fiat is necessary to fully realize the advantages of blockchain in the traditional markets.
DAI was founded by Rune Christensen — head of DAO Maker. The first meeting on this development took place in early 2016 and was officially launched on December 18, 2017.
The coin is created and liquidated precisely by its users using the established algorithm. The token is created and located on the ethereum platform and is completely decentralized and open to the public. With the help of the collateral, DAI provides a guarantee of what is attached to the valid assets and is also freely available for exchange.

Free TON (TON Crystal)
Release date: 2020
Website: https://freeton.org/
TON Crystal is a peer-to-peer token ( Free TON ) established on the Telegram Open Network protocol which was developed by the Telegram team. After Pavel Durov left the project due to pressure from American regulators, a community of 5,000 individuals and independent developers continued to develop the platform which eventually led to The Free TON being launched in May,2020.
The Declaration of Decentralization (DOD) of the Free TON Blockchain Platform sets out the project’s main values — protecting the free market, personal data, and resisting censorship through decentralized management.
