# # Why are there multiple types of clients? In the early stages of the Ethereum project, several different clients have been implemented on many different operating systems, which is a huge triumph for the entire ethereum ecosystem. It allows us to verify the clarity of the agreement (as specified in the Ethereum [(https://github.com/

, and then we can start to really program. programming language for writing smart contracts It's good to use solidity. There are several languages available to write smart contracts: a bit like JavaScript solidity, the file extension is. Sol. And Python close to the serpent, with the file name ending with. SE. There are also lll like Lisp. Serpent has been popular for some time, but now the most popular and most stable to be considered solidity, so with solidity good. I heard you like python? Wi

able to fill the electricity bill, but who knows later. People are creating a lot of cool dapp that might make ethereum more and more popular. Interactive consoles. After the client runs, you can synchronize the blockchain, build the wallet, and send and receive the etheric currency. One way to use Geth is through the JavaScript console (JavaScript console, like the one you press F12 in Chrome, just run in the terminal). You can also use the curl-lik

tokens in people's wallets, but it also stores the latest status of each smart contract and the code for each smart contract. Blockchain is a distributed ledger stored in multiple locations, so this means that smart contract data is stored by those ethereum nodes. If you create a "smart contract" (also known as an application) on a blockchain, it is stored and run in a distributed manner. For comparison, c

for computation. Fast synchronization does not process the entire blockchain through a single link, but rather replays all transactions that occurred historically, and fast synchronization downloads the transaction documents along those blocks and pulls the entire recent state database. This allows fast-synchronizing nodes to still maintain the state of their archive nodes that contain all the historical data for user queries (and therefore does not generally affect the health of the network),

This is a creation in Article, where the information may have evolved or changed. After learning from various sources, we decided to start building a private chain environment based on Ethereum Go-ethereum.

Ethereum History For recent history, please see the Taylor gerring blog post. Birth At the same time, Vitalik began working with Dr. Gavin Wood to create Ethereum. In April 2014, Gavin published the Ethereum Yellow Book as a technical note for Ethereum virtual machines. As specified in the Yellow Book, the

can contract code is run in the Ethereum Smart contract virtual machine. Document: Https://solidity.readthedocs.io/en/latest/installing-solidity.html#building-from-source We see the above section similar to Golang in the interface code, which contains the total amount, balance, transfer and other methods. Our focus today is actually to use Golang to achieve transfer, Transferfrom method. Connecting
