The tools included in the warehouse are: A Test Account import script that imports five test account private keys into the Ethereum node at first deployment.A Genesis.json configuration file that provides initial funding (etheric currency) for the corresponding five tes

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

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
