1. The full English name of Ethereum is Ethereum, and the symbol of Ethereum is three horizontal bars (Ξ), also called ETH and ether.

2. Ethereum, is a blockchain technology, an open source platform that can create and publish decentralized applications (Đapp), and ultimately achieve a decentralized Internet. Many believe that it is one of the most promising decentralized smart contract protocols out there.

3. Ether, the native token of Ethereum, has two purposes: first, applications (Đapp) need to pay for every operation they make, which can prevent corrupted or malicious programs from going out of control; Second, ether is a reward for those who contribute their resources to the decentralized network.

4. Ethercoin is not Ether. The Ethercoin team is a third party team and has no affiliation with the Ethereum team, do not buy Ethercoin.

5. In September 2014, Ethereum raised a total of 31,531 bitcoins through the pre-sale. According to the bitcoin price at the time, Ethereum successfully raised more than 18 million US dollars. According to CoinTelegraph, Ethereum "is the most successful public One of the projects that will go down in history.”

6. The pre-sale lasted for 42 days. In the first two weeks of the pre-sale, one bitcoin could buy 2,000 ether (the price of bitcoin was around 3,500 yuan at the time, that is, the purchase price at that time was 1 Ether = 1.7-1.8 yuan), The amount of ether that one bitcoin can buy decreases over time, and in the last week, one bitcoin could buy 1,337 ether.

7. The final amount of ether sold is 60102216. And 0.099x (x is the total amount of sale, i.e. 60102216) ETH will be allocated to early contributors who participated in the development before BTC financing or other deterministic financing is successful, and another 0.099x ETH will be allocated to long-term research projects. Therefore, when Ethereum was officially released, there were a total of 60102216+60102216 * 0.099 * 2 = 72002454 ETH.

8. Ethereum will use a hybrid security protocol, using proof-of-work (POW) in the early stage to distribute ether, and then switch to proof-of-stake (POS). Since the launch, there will be 0.26x every year, that is, 60102216 * 0.26 = 15626576 ethers are mined by miners every year. After switching to POS, the annual output of ether will be reduced.

9. 'Frontier' is the first milestone released by the Ethereum project, a technical release focused on developers, not a version for ordinary users. Be aware that early software is often vulnerable to bugs and has unstable and complex user interfaces. If you don't know how to compile, build, and run applications from source code and a command-line interface, we strongly recommend that you wait for a subsequent version of Ethereum.

10.  Yunbi.com is the first platform in China to support ether trading, and currently ranks fourth in the global trading market, with sufficient depth and liquidity to meet users' trading needs.
