block, and will automatically adjust the calculation difficulty according to the previous time out of the block, but not due to the hardware development and other factors caused the speed change. In addition, the random number of bytes is not very large, Bitcoin is 4 bytes. In the mining, the nonce random number is unknown, to try from 0 to 232, but this number is not small, only 4294967296, to the current mining machine 14T per second of the calculation, all calculate to the upper limit also d

supplement this information, while introducing some basic developer tools that make it easier to get started in the ether, smart contracts, and build dapps (decentralized apps, distributed applications). I will try to explain what every step of the workflow is doing in my own (still novice) understanding, and I get a lot of help from Consensys cool developers. Basic Concepts Getting to know these nouns is a good start: Public key encryption system. Alice has a public key and a private key. She

generated public key can be compressed, The compressed public key has only 33 bytes, and the uncompressed public key has 65 bytes. The compressed public key is more important to Bitcoin because Bitcoin is a centralized, peer-to-coinbase crypto currency, each node has a complete transaction record, and each transaction will send a public key, in addition to the ore-mining bitcoin, and the public key is supported in the compressed format, and the trans

This article is based on the Geth client mentioned earlier in this article, explaining how to build your own private chain, as well as account management and transfer transactions. 1. The Genesis block file The first chunk on the blockchain is called the Genesis block, and the creation of our private chain can be declared and defined by the creation block configuration file. Store the following file contents as a Genesis.json file { "Coinbase": "0

install Ubuntu System on window to build a private chain operation steps The premise is that Geth has been installed, you can refer to the previous section to explain Step 1: Create a directory and Genesis.jsonCreate a directory in command-line mode, such as Geths, where the geths directory is named arbitrarily. Command: mkdir geths then a geths folder appears in the Ubuntu directory. Continue to enter the folder directory, create a file, Genesis.json, file name can also be arbitrary. Genesis.j
