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 material factual errors were identified: (1) the FTC '$1 billion / 46,000 victims' statistic is dated to May 2021 in both the section text and timeline, but those figures come from a June 2022 FTC report — the May 2021 FTC report cited documented far smaller losses; (2) the October 2024 scam is described as coinciding with a 'Falcon 9 booster catch test,' but the event was SpaceX's Starship IFT-5 (a Super Heavy booster catch — a different vehicle). The Robinhood section heading incorrectly labels the incident as '(2024)' when it occurred in June-July 2025. The CRDF/Fortinet classification claim for spx-coin.com could not be verified from the cited sources. The specific '164,000 concurrent viewers' figure for the April 2024 solar eclipse stream is not supported by the OECD source cited, which says only 'tens of thousands.'","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
