how to make blockchain

After more than 10 years of development, go language has become the most popular emerging language. At present,go language has become the preferred language in cloud computing, and with the popularity of blockchain in recent years, as the bottom of the development of the language go again hot become the Blockchain technology training field first programming language, IBM's fabic and other heavyweight

This article is from: "Blockchain technical Guide" section, hereby explained. Hash algorithm Defined Hash (hash or hashing) algorithms are very basic and very important technologies in the field of information technology. It can map any length of binary value (plaintext) to a shorter fixed-length binary value (hash value), and different plaintext is difficult to map to the same hash value. For example, the MD5 hash value for a paragraph "Hello

When it comes to blockchain storage, it's easy to think of its chained storage structure, but the blockchain has evolved from Bitcoin to today's most popular EOS, and technology has been evolving for 10 of years. The current EOS storage, in addition to confirming the chained storage of the structure, has made a great progress in state storage, especially after the introduction of MongoDB plugin, which can b

Understanding the concept of blockchain is simple (block chain, trading chain block): It is distributed (ie not placed on the same machine, different network devices on the) database to support the hosting record of the growing list. However, it is also easy to confuse blockchain with the idea that we are trying to help him solve the goal--at that moment in people's minds, the word is pretty strong about tr

At present, the mobile Internet, the blockchain more and more, in the blockchain security, a lot of the existence of the website vulnerability, the recharge of the blockchain and withdraw, the membership account of the storage of XSS theft vulnerability, account security, and so on these blockchain loopholes, we sine s

In layman's words, a blockchain is a general ledger that includes all the historical transactions, and each chunk contains several transactions. If the blockchain is a ledger, then chunks are every page of the ledger. The details of the transaction are recorded on a public ledger that can be seen by anyone on a network. A chunk is a collection of many transaction data, Fang Hua a

In the first two articles of this series, we showed you how to implement a simple blockchain with refined Java code. including building blocks, validating block data, broadcast communications, and so on, this article focuses on how to implement the POW algorithm. Everyone exclaimed about the continuing frenzy of Bitcoin, Ethereum, and other cryptocurrency, especially for newcomers to the field, who are constantly hearing Dick and Harry collect te

Blockchain Enthusiast (qq:53016353) "There is a virus in the digital currency block chain. ” When the news spread on the internet, digital money was pushed to the limelight. While this actually only affects a small number of digital money enthusiasts who have downloaded all the blockchain data, for bit-black, it will undoubtedly allow them to find a new point of injection. In fact, as the popularity

What is a consensus algorithm. Blockchain architecture is a distributed architecture. Its deployment mode has three kinds of public chain, alliance chain and private chain, corresponding to decentralized distributed system, partial decentralized distributed system and weak center distributed system. In distributed systems, multiple hosts compose network clusters by means of asynchronous communication. In such an asynchronous system, there is a need f
