Nockchain is a layer-1 blockchain that uses a consensus mechanism called Zero-Knowledge Proof of Work (ZKPoW). In this model, participants generate zero-knowledge proofs to validate blocks and maintain consensus, rather than relying on hash-based proof of work. Proof verification takes place on-chain, while most computation occurs off-chain.

The native token NOCK is issued through the mining process defined by the protocol. The network launched without a pre-mine or private allocations, and token issuance follows a fixed schedule defined at genesis. Nockchain includes a programmable execution environment where applications can submit off-chain computation results that are verified on-chain using cryptographic proofs.

NOCK is required for core protocol operations and economic activity within the system:

• Transaction fees: NOCK is used to pay for submitting transactions to the network, with fees based on transaction size.
• Block production and consensus: The token is issued as a reward to miners who produce valid zero-knowledge proofs and extend the blockchain.
• On-chain data costs: NOCK is used to pay for storing data and maintaining data availability required for proof verification.
• Value transfer: The token can be transferred between accounts as the network’s native currency.
• Protocol interaction: Users and applications use NOCK when interacting with protocol-level functions and smart contracts.
