This kind of network credit currency is bitcoin (

After the time a chunk is generated in the Bitcoin network, an authorized Equity certificate system (DPOS) allows your transaction to be verified by 20% of shareholders, while the Bitcoin network declares that the transaction has been almost irreversible (6 blocks

hackers, SO 2 + 2 = 5-Although cryptography and mathematics may be mistakenly used. If a system using cryptography is cracked, it is only possible that the designer mistakenly applies cryptography. This is not because cryptography does not work, it's not because someone "cracked" Cryptography-it's not a mathematical error when your bank mistakenly handled your account, and your mom was infected with computer viruses by downloading unfamiliar attachments. is not the same as an email error.

The unprecedented transparency of trade has unnerved financiers. To cut costs, banks are racing to adopt block chains (the underlying technology of bitcoin), but technicians and business people have to make drastic changes to keep this radical technology in line with the rules of the banking world. E-currency Bitcoin was invented in 2009 to create a monetary system that is not controlled by governments and

backward 1 letter is the 加密 process, forward is the 解密 process, and this rule is 算法 . This simple encryption and decryption process is called "symmetric encryption." The disadvantage is obviously, must have to call to tell the girlfriend how to decrypt, do not know walls have ears.Of course, the safer way is not to call and handle. Nature is here the private key and the public key, they are long string values, the private key is like a bank card password, the public key is like a bank card acco

In the previous chapter, we mainly described the block chain, block, mining and so on, set the data format of the block, realize how to encrypt the block into the block chain to ensure the effectiveness of the block chain, and we also through the design of a data problem, It is necessary to have a certain computational power (PoW) to prove that a block is a new block in the block chain. In this chapter, we will implement the following features 1. Create a simple wallet (wallet) 2, use our block

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
