Description

Nockchain is a next-generation Layer-1 blockchain that merges classical Proof-of-Work (PoW) security with modern zero-knowledge proof (ZK) technology to create a fully verifiable, programmable, and decentralized computation network. Launched on May 21, 2025, Nockchain aims to extend the foundational principles of Bitcoin into the era of verifiable computation and scalable smart contracts. At its core, Nockchain introduces a consensus model called Zero-Knowledge Proof-of-Work (ZKPoW). Instead of simply hashing random values as in traditional PoW, miners must compute and submit a zero-knowledge proof of a deterministic computation task. The hash of that proof serves as the block’s nonce, meaning that mining power directly corresponds to performing provably useful computation rather than pure energy expenditure. This approach maintains PoW’s robust economic security while adding verifiable utility to each mined block. The chain targets a 10-minute block time and employs dynamic difficulty adjustments similar to Bitcoin’s, ensuring predictable issuance and network stability.
