What is a hash function in a blockchain transaction?

WebAug 14, 2024 · A cryptographic hash function is a mathematical equation that enables many everyday forms of encryption, like digital signatures. This includes everything from the HTTPS protocol to payments made on e-commerce websites. Cryptographic hash functions are also used extensively in blockchain technology. 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.
