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.

around an algorithmic stablecoin pegged to 0.001 ETH. On February 20, 2023 — the same day the platform went live — approximately $2 million (1,095 ETH) was drained from its Genesis Rewards Pool in what blockchain security firms CertiK and PeckShield assessed as an insider-orchestrated exit scam, making it the largest exit scam recorded on Arbitrum at that time. Stolen funds were bridged to Ethereum and routed through Tornado Cash; the protocol's website subsequently went offline and the team became unreachable.","timeline":[{"date":"2023-01-01","event":"Hope Finance Twitter account created; project announced plans for an algorithmic stablecoin (HOPE token) pegged to 0.001 ETH on Arbitrum.","source":"CoinTelegraph","source_url":"https://cointelegraph.com/news/hope-finance-exploit-results-in-2m-stolen-from-users-funds"},{"date":"2023-02-01","event":"Cognitos completes smart contract audit of Hope Finance, flagging reentrancy risks and an incorrect modifier but marking the contract as having passed the audit.","source":"CoinCu News","source_url":"https://coincu.com/168666-hope-finance-appears-rug-pull/"},{"date":"2023-02-20","event":"Hope Finance launches on Arbitrum.
