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.

The most material factual error — appearing in two separate sections — is the claim that Exponent 'won' the Colosseum hackathon; authoritative sources (Colosseum's official blog and Solana's own announcement) confirm Exponent placed 5th in the DeFi & Payments track, with a different project winning. Additionally, the V2 upgrade announcement is dated to 'late 2025' and attributed to 'Breakpoint 2025,' while the cited source is a December 2024 article covering Breakpoint 2024. One dynamic metric (current TVL/fees) is directionally plausible but could not be verified via direct source access.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
