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.

Two factual errors require correction before the page is republished: claim_findings[4] and claim_findings[22] both assert Exponent 'won' the Colosseum hackathon, which is directly contradicted by two Tier 2 sources (Colosseum's official blog and Solana's own announcement) confirming Exponent placed 5th in the DeFi and Payments track. Additionally, claim_findings[24] dates a Thomas Lefort presentation to 'Breakpoint 2025' (November 2025) when the sole cited source is a December 2024 article covering Breakpoint 2024, placing the event approximately 14 months earlier than stated. These are correctable wording errors, not integrity failures, and do not affect the core trust assessment.","score_delta":-8,"sequence_num":5,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
