ZK Rollup Proof Explainer

WHAT IT DOES

ZK Rollup Proof Explainer is a read-only tool that analyzes on-chain data for ZK rollup proofs and generates AI-powered plain-language explanations of verification status and validity. It reads ZK proof verification status, rollup state root, proof submission data, validator signatures, verification key, protocol parameters, batch commitments, L1 finalization state, proof generation details, and verification success or failure logs. The tool then presents this data alongside an AI-generated explanation of the proof's status and validity, including verification status, what state transition it proves, and any potential risks or concerns — helping you understand the proof's integrity before initiating or monitoring a batch submission.

HOW TO USE

Connect your wallet using the BGWallet bridge and select your target network (Ethereum Mainnet is recommended for L1 verification checks). Enter the rollup contract address — you vouch for this contract, not the tool. Enter the proof ID or batch number you want to verify. Optionally specify the rollup name. Click "Analyze ZK proof" to read on-chain data. The tool displays the rollup contract, proof ID or batch, rollup name, verification status, state transition description, and a verification key. Detailed information includes state root, validator signatures, protocol parameters, batch commitment, L1 finalization state, proof generation details, and verification logs. A validity confidence meter visually indicates the verification confidence level. An AI explanation appears below the on-chain data, describing the proof's status and validity, including verification status, what state transition it proves, and any potential risks or concerns. The wallet's own signature step still protects you — this explanation is informational only and does not replace reviewing what you approve in your wallet.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 with the provider from the BGWallet bridge to read on-chain data from the contract you specify. No hardcoded contract addresses are used — you are always in control of which contract you trust. When analyzing ZK proofs, the tool reads verification status from the rollup's verification contract (e.g., verifyProof(), getProofStatus()), state root from the state commitment contract, proof submission data from the proof registry or batch submission contract, validator signatures from the signature verification contract, verification key from the verification key registry, protocol parameters from the parameter storage, batch commitments from the commitment contract, L1 finalization state from the L1 bridge or finalization contract, proof generation details from the proof metadata, and verification success or failure logs from event logs (e.g., ProofVerified, ProofInvalid). The tool fetches event logs by walking backwards in chunks and halving chunk size on failure, ensuring logs are properly read despite varying RPC limitations. The data is formatted and passed to the AI bridge via BGAI.generate() with a structured prompt that includes all the on-chain data read. The AI is instructed to explain the proof's status and validity including verification status, what state transition it proves, and any potential risks or concerns — while stating plainly that it cannot verify the mathematical validity of zero-knowledge proofs directly, cannot detect off-chain proof generation flaws or trusted setup compromises, and cannot guarantee that verified proofs accurately represent the claimed state transition. The AI response is capped at 1,024 tokens to ensure concise, focused proof assessments. All computed values are guarded against negative numbers — if a verification confidence score appears invalid, the tool flags it rather than displaying nonsensical values.

WHAT IT CANNOT SEE

This tool cannot verify the mathematical validity of zero-knowledge proofs directly. It cannot detect off-chain proof generation flaws, trusted setup compromises, or cryptographic vulnerabilities. It cannot guarantee that verified proofs accurately represent the state transition they claim to prove. The AI explanation is generated from on-chain data only and cannot detect hidden proof generation errors, cryptographic weaknesses, trusted setup issues, or verification bypasses. It cannot predict future proof generation failures, validator compromise, or cryptographic vulnerabilities that may be discovered later. The tool does not continuously monitor proofs; each analysis is a snapshot at the time of the lookup. It cannot detect off-chain proof generation latency, delayed verification, or stale verification keys. The tool does not store any data persistently; all state is in-memory and resets on reload. The AI explanation is informational and does not constitute cryptographic advice, financial advice, or a guarantee of proof validity.

PLEASE NOTE

ZK Rollup Proof Explainer works exclusively with EVM-compatible chains. It requires a Web3 wallet (MetaMask or similar) and the BGWallet bridge. Explanations are AI-generated from data the app reads on-chain — always review what you are actually signing in your wallet before approving it. Always verify the rollup contract address you are using — the tool does not validate or endorse any contracts. ZK rollup proofs carry significant risk including potential proof generation errors, trusted setup compromises, verification bypasses, and cryptographic vulnerabilities. Use this tool as a guide only; always cross-check with the rollup's official interface and independent sources for critical decisions. This is experimental software; use at your own risk.
