So, what exactly is a block chain? block Chain A digital ledger that records transactions publicly in chronological order in Bitcoin (Bitcoin) or other encrypted currency. In

a limited time certificate to view the books and transaction details, thus making an accurate assessment of the operation. Digital currency is the implementation of blockchain technology, Bitcoin can be used as a simple application on the basis of digital currency construction. The digital currency uses a modular architecture that allows different components to plug and Play based on the implementation protocol. Powerful container technology can be used to run mainstream programming languages

The rise of digital currencies over the past few years has largely depended on Bitcoin, but after all, Bitcoin is a limited number and is likely to be replaced by other digital currencies in the future. We can also see a lot of digital money development tutorials on the network, if the code is more proficient, found the template after the modification, or can save a certain amount of time. But the way digit

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
