Background

With the continuous development of internet finance, payment is an indispensable important link in internet transaction, but many security risks are exposed, so that a security guarantee needs to be provided for payment. It is known that if the plaintext is directly hashed and encrypted, a hacker can easily obtain the plaintext by obtaining this cryptographic hash value and then by looking up the hash value dictionary. Salt is added, namely salt, which is an extra random value added in the password hash process, so that the problem can be effectively solved. The block chain technology has the characteristics of distributed storage and non-tampering, and ensures a secure payment environment by combining hash encryption.
