financial complexities of raising funds through Presale have led to the birth of several legal entities, including the Ethereum Fund (Stiftung Ethereum) established in Zug, Switzerland, in June 2014.
Since June 2014, Ethereum has allocated the first etheric currency with a 42-day pre-sale of the etheric currency, earning 31,591 Bitcoin at the time, valued at $18

In doing some testing, it may be necessary to build a private ethereum network to facilitate control and to get to the real test work faster.While the Ethereum nodes can link to each other need to meet 1) the same protocol version 2) the same networkid, so the most convenient way to build a private network is to use the--networkid option in the Geth command to set a different networkid from the main network

In this article, we have used the remix environment to run and test the first smart contract program written in this book. However, there are many testing methods for writing and testing smart contracts, for example, testing in the testrpc environment; in intellij idea integrated development environment, you can use the solidity language to write smart contracts, test smart contracts in a pure
