Understanding zk-SNARKs: Ensuring Privacy in Blockchain Transactions

By: Isha Das

Zero-Knowledge Succinct Non-Interactive Argument of Knowledge (zk-SNARK) is an advanced cryptographic concept that ensures privacy and scalability in blockchain transactions. zk-SNARKs enable one party to prove to another party that a statement is true without revealing any details about the statement itself. This is particularly useful in the context of cryptocurrencies, where users might want to keep specific transaction details confidential while still maintaining the integrity and transparency of the blockchain.

zk-SNARKs have been implemented in various blockchain protocols to address the privacy concerns associated with public ledgers. The key advantage of zk-SNARKs is that they allow for succinct proofs, meaning the proof can be very short in length, and non-interactive, requiring no back-and-forth communication between prover and verifier.
