Verify a decision

Every moderation decision on AVOID.NET is anchored to the Solana blockchain. You don't have to trust us — you can verify cryptographically that we committed to a verdict at a specific moment and have not rewritten it.

How verification works

  1. We commit. When a moderator accepts/rejects a submission, we serialize the decision into deterministic UTF-8 bytes (payload_canonical_string), hash it with SHA-256, encode the digest as base58, and write it to Solana inside an SPL Memo v2 transaction.
  2. We store the bytes. The exact bytes we hashed are stored alongside the decision in our database. Anyone can read them and recompute the hash in any language.
  3. You compare three values. Database hash, your independently-recomputed hash, and the hash inside the on-chain memo. If all three match, the decision is authentic and timestamped.
The on-chain memo format is AVOID.NET|v1|h:<b58-sha256>|d:<id>|t:<iso>

Find a signature on any investigation page's decision log, or run python -m src.verify_decision --signature <sig> for a CLI check.

On August 10, 2021, it suffered a critical smart contract exploit due to a missing access-control modifier in its CompoundModel contract, resulting in approximately $8.95 million in stablecoin losses; roughly $5 million was partially recovered via a white-hat frontrunner who retained a $1 million bounty. The project launched without a security audit, has published no meaningful updates since late 2021, and its PUNK token currently trades at effectively zero volume, indicating the project is dormant or abandoned.","timeline":[{"date":"2021-06-01","event":"Punk Protocol announces fair launch; team led by pseudonymous contributors 0xJohnny and 0xMateo; contracts described as pending audit","source":""},{"date":"2021-08-10","event":"Smart contract exploit occurs; attacker uses delegateCall to exploit unprotected initialize() function in CompoundModel, draining approximately $8.95 million in USDC, USDT, and DAI","source":""},{"date":"2021-08-10","event":"White-hat frontrunner bot intercepts approximately $6 million of the drain before the attacker can secure it; stolen USDC routed through 1inch and Tornado Cash","source":""},{"date":"2021-08-11","event":"Punk Protocol publishes incident report; suspends deposits and withdrawals; commits to unconditional compensation of all affected users","source":""},{"date":"2021-08-13","event":"White-hat actor returns approximately $4,954,250 in USDT and DAI after retaining approximately $1 million DAI as a finder's fee","source":""},{"date":"2021-09-01","event":"Punk Protocol publishes compensation plan; issues 4,041,504 peUSD tokens to affected users; freezes 3,150,000 PUNK contributor tokens pending full recovery; announces NFT drop and protocol revenue as funding mechanisms","source":""},{"date":"2022-01-01","event":"Last known substantive public communications from Punk Protocol; Medium blog activity ceases","source":""},{"date":"2026-05-27","event":"PUNK token reports $0 price and zero trading volume; project appears dormant; Recovery Fund completion status unconfirmed","source":""}]},"v":1}
