SHA 256 is the name of a cryptographic hash function. SHA 256 derives its name from the acronym Secure Hashing Algorithm. The main task of SHA 256 is to generate 256-signatures for generating addresses, private keys that are used in Bitcoin blockchain and some other projects. SHA-256 is used to protect the blockchain from attacks and can be forced by brute force (spending computational resources on finding the match letters+symbols combination that will give access to a private key). The other function of SHA-256 is making hashes and block linking. 

Sharding is an application scaling strategy. Within the framework of sharding, information from a common database is divided into blocks and distributed among different servers, which are called shards. The process of using this strategy is called sharding. Sometimes you can come across the term partitioning – this is part of sharding. This is the name of the process of dividing the database, before moving it to separate servers.

Verification method between verifier and verifier. In a zero-knowledge proof system, the verifier can prove to the verifier that he possesses knowledge of a specific piece of information (for example, solving a mathematical equation) without disclosing the information itself. These verification systems can be used by modern cryptographers to provide enhanced privacy and security.
