Zero-knowledge proof finds new life in the blockchain

ZKP has decades of history in computer science and cryptography. Now, it's evolving to support decentralized authentication for blockchains and web3.

A zero-knowledge proof, also known as ZKP protocol, attempts to establish a fact between parties with a minimum amount of information exchange. In cryptography, it is intended to limit the transfer of information during authentication activities. ZKP's originators explicitly studied the movement of information, or knowledge, in computer proofs. The zero-knowledge proof was a significant advancement in introducing a new area of study at the time. Its implications are being explored again today in the context of web3 and blockchains.

Zero-knowledge proof vs. asymmetric encryption

The idea of the zero-knowledge proof comes out of the '70s and '80s era of exploring new conceptual territory in cryptography. This is the same milieu that bro...
