Objective The first two articles simply implement blockchain creation and proof of workload, but they are all in memory. The actual blockchain should be stored permanently, which makes sense. A permanent blockchain storage is started

Trading Mechanism:1. Blockchain can store transaction results safely and reliably2, in the blockchain, once the transaction is created, no one can modify or delete3, the transaction by some input and some output combination4. For a new transaction,

First of all we need to understand what CODEC means. It is Coder + Decoder = Codec, which is the encoder decoder. That is, the encoder is also the decoder.Website address: http://commons.apache.org/proper/commons-codec/Apache Commons Codec (TM)

Bufio implements buffered I/OBytes provides functions for byte slicing.Crypto collects common encryption ConstantsErrors implements the function with incorrect operationsExpvar provides a standard interface for public variables, such as the

1 sha Encryption: Secure Hash algorithm is mainly applicable to digital signature algorithms (Digital Signature algorithm DSA) defined in the digital signature standard (Digital Signature Standard DSS). For messages that are less than 2^64 bits in

What is a JWT?The full name of the JWT is the JSON Web Token, a concise, URL-safe declarative specification for communicating security information between the two parties. JWT, as an open standard (RFC 7519), defines a concise, self-contained method
