1. Installing the Geth Client Enter the command: sudo add-apt-repository-y ppa:ethereum/ethereum#启动PPA储存库 sudo apt-get update#访问源列表里的每个网址, and read the software list and then save it to your computer sudo apt-get install Ethereum#安装Go Ethereum 2. Check after installation is complete Using commands Geth versionTo check if the installation was successful

the nodes are beginning to upgrade to the new version, then the old node maintenance chain can survive depends on how much power, this is called a hard fork. Obviously, the most superficial understanding is the soft fork or a chain, the hard fork will be divided into two chains. There are over-forks in Ethereum and Bitcoin, and what are the pros and cons of soft forks and hard forks in practical applications for real-world applications: The soft fork

Click on the "Blue word" above to follow us. Author: Christopher Tozzi Translator: Pencil case If your technology doesn't scale, it probably doesn't have any meaning at all. At least, in the real world there is no use in any sense. Blockchain-based media is no exception. In order to be able to apply in the media domain, blockchain technology must be scaled up to accommodate and increase user and demand. Bitcoin-based media blockchain is facing a huge challenge. Traditionally, Bitcoin has n

the globalization has been running for many years in a stable. Bitcoin transactions between any two accounts are faithfully recorded on a large number of redundant ledgers. In a bitcoin network, any account is anonymous, and any transactions between accounts are non-tamper-proof and are recorded on each node. Then through to the mining of bitcoin incentive mechanism to achieve the self-operation of this network, without any centralized trading system. Aether Square So what is

Before starting to learn each technology, the first task is to build a variety of development environment, and the development environment of block chain is more troublesome. Here we come to a complete realization. The following actions are done under Mac. (1) Install PYTHON2.7,MAC Use the following command directly in the terminal: Brew Install Python (note python is lowercase) (2) Install SOLC (solidity language compiler) and execute the following command in the terminal: sudo npm install-g So

transaction has the direction to prevent cheating behavior. Modeling Business Scenarios For the second section of the two cases, we are going to model, remove the core pain point, we must also have the requirements of accounting, in essence, in any case each node is both a service side, and customer side, then how to measure their contribution and how much to claim. Therefore, any blockchain platform must have a token system, otherwise the accounting will be very difficult. In the business

Ext.: https://blog.csdn.net/pony_maggie/article/details/79588259 Reading this article requires a basic understanding of the concepts of Ethereum, smart contracts, tokens, and so on. What is ERC20 ERC20 can be simply understood as a token agreement on Ethereum, and all tokens based on Ethereum are subject to this agreement. The tokens that follow these agreement

A simple smart contractStart with a very basic example, and don't worry that you don't know it at all, and we'll get to know more details.Storecontract SimpleStorage { uint storedData; function set(uint x) { storedData = x; } function get() constant returns (uint retVal) { return storedData; }}In solidity, a contract consists of a set of code (the function of the contract) and the data (the state of the contract). The contract is located at a special address on the
