1. Block is the base unit of the block chainA block chain consists of several blocks, which are the base units of the blockchain.2. The basic attributes of chunks in a block chainDescription of the chunk 6 attribute-index The index value of the chunk, the unique key in the blockchainDescription of the Block 6 attribute-timestamp chunk timestamp, used to differentiate the generation time of a chunkDescription of Block 6 properties The hash value of the

Calculation of the hash value of chunks in Java block chainThere are many methods of calculation, such as, can be directly splicing string, can also be used StringBuffer, or StringBuilder. It uses a faster StringBuilder, and can use stringbuffer when programming.Where index is the index of block block, timestamp is the time stamp of block block, data is the block contained in the chunk, the nonce is the difficulty coefficient of the block. The overall calculation code is as follows: /** * 计算

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

(approximately 4 years). The network tries to create 6 chunks per hour. Every 2016 blocks (approximately two weeks), all Bitcoin clients compare this target to the number of blocks actually created, modifying the percentage of difficulty the chunk collects to maintain this goal. The client considers the "longest" blockchain to be valid. The "Length" of the entire blockchain refers to the chain with the mos

The two companies announced the partnership at the Sydney Investor Conference, the Sydney Morning Herald reported. The initial cooperation project was the application of the Australian Securities market, and it was clear that the project attracted a lot of attention, since the major Australian exchanges have already started a distributed ledger exploration. Australian Equity Transfer Service company and blockchain start-up companies to build equit

Proof of workload (proof of work)One key to blockchain is to add a threshold for security and stability: If a participant wants to create chunks and join a blockchain, it must prove that he has done a very difficult job, which is "proof of work", or POW. Can be understood as POW used to keep the rhythm of the blockchain.The difficulty of work is reflected by the amount of computation, which cannot be comple

Due to the current user's lack of knowledge of the blockchain, coupled with the shortage of professionals in the blockchain and the lure of high salary, the market has spawned a number of blockchain training institutions. Brother Yun Jong, president of the Blockchain training Institute, says consumers need to be carefu

As already mentioned in the previous article, Bitcoin is a decentralized, distributed ledger, so the nodes are not trusted by each other. So how do all the participants in the Bitcoin network reach a consensus on any ownership? This article will show you how to solve this problem.The bitcoin consensus is generated by the interaction of the 4 independent processes of all nodes:1. Each node (mining node) independently verifies each transaction according to the standard2. Mining node by completing
