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
- 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. - 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.
- 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.

Of 8 countable findings, 2 could not be verified (claim_findings[1] TVL drop, claim_findings[7] no disclosed attacker addresses), giving 25% disputed; one further finding was excluded because the source blocked the reviewer. Three claims were only partly supported: the Sept 15 patch date is inferred (claim_findings[3]), the Minswap snapshot was taken hours after the attack (claim_findings[4]), and the Catalyst Fund 11 funding has no cited source (claim_findings[8]). The page also rests on secondary news with high-priority gaps in primary sources and on-chain data, so a small penalty applies; no omission or status change contradicts the page.","reviewer_def_hash":"bc11388ce4bc4deea1b064fea362663ae06e3f4f687f99604769044d6ffba770","score_delta":-8,"scored_claims":8,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
