WebTo achieve blockchain redacting in a fine-grained and controlled way, Derler et al. proposed a novel cryptographic primitive, named policy-based chameleon hash (PCH), and introduced it into the blockchain redacting . Anyone who satisfies the policy embedded in the transaction could then find arbitrary collisions for a given hash. WebKey Highlights. Cryptography is a field of math and includes the study of encryption, hash functions, and digital signatures. The Bitcoin network uses hash functions to ensure the blockchain’s security and immutability. Bitcoin uses public key-based digital signatures to allow users to send bitcoin trustlessly.

WebBlockchain’s solution to the Byzantine generals’ problem is cryptography. A blockchain network uses cryptographic techniques at two levels that keep the data secure. One is the key-encryption method and another is hashing. Key encryption is a cryptographic method that ensures safe transmission of information from point A to point B.
