A cryptographic method that lets one party prove a statement is true without revealing any information beyond the fact that it is true.
A zero-knowledge proof (ZKP) lets a prover convince a verifier of something, such as I know the password or I am over 18, without disclosing the password or the exact birth date. The idea was introduced in academic research in the 1980s and has become practical with modern cryptography.
In blockchain, zero-knowledge proofs enable private transactions and power zk-rollups, layer 2 systems that bundle many transactions off-chain and post a compact proof to the main chain, improving scalability. Beyond crypto, ZKPs are being explored for privacy-preserving identity verification, secure voting, and proving compliance without exposing sensitive data. Generating proofs can be computationally intensive, though tools and hardware acceleration are improving.
A shared, append-only digital ledger in which records are grouped into blocks that are cryptographically linked in sequence.
EncryptionThe process of converting readable data into scrambled ciphertext that only someone with the correct key can decode.
EthereumA programmable blockchain platform, launched in 2015, that runs smart contracts and has its own cryptocurrency called Ether.
