Blockchain Enthusiast (qq:53016353) Digital currency is the best programming platform in the area of blockchain development, and truffle is the most popular development framework of digital currency (Ethereum), this is our first Blockchain technology article introduced truffle reason, the actual combat is the most important thing, this article does not talk about

chunk is 50, which is halved per 210,000 blocks (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

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

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
