Dogecoin’s Proposed On-Chain Zero-Knowledge Proof Verification

Summary

The document describes a proposal to add OP_CHECKZKP to Dogecoin Core so scripts could verify zero-knowledge proofs on-chain. It introduces zero-knowledge proofs as a way to demonstrate that information is valid without disclosing the information itself, and identifies Groth16 as the proposed initial proof system. The article gives an approximate validation time and limits of one proof per script and five per block, presenting these constraints as safeguards for network performance.

It also outlines possible applications, including private transactions, decentralized finance, non-fungible tokens, bridges, and zk-rollups, and mentions a separate Ethereum-compatible zero-knowledge virtual machine under development. Older nodes are said to treat the new opcode as a no-op. These are proposal descriptions and anticipated benefits, not evidence of a deployed upgrade or measured results. The discussion of trade-offs is incomplete, so it does not assess implementation costs, security assumptions, or adoption requirements in depth.

Key ideas

• The OP_CHECKZKP proposal would let Dogecoin scripts verify zero-knowledge proofs on-chain.
• Groth16 is proposed as the initial proof system, with per-script and per-block usage limits.
• The article identifies privacy, rollups, and cross-chain applications as potential uses rather than demonstrated outcomes.
• Older nodes are described as treating the opcode as a no-op to preserve backward compatibility.
• The document does not establish deployment status or quantify the proposal’s costs and security assumptions.
