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.

Two of eight checked claims could not be traced to their cited source: the address-rotation allegation (claim_findings[2]) and the attribution to Chainalysis of likely control of Bitpapa by a named individual (claim_findings[3]), giving a 25% unverified share. Two further claims were only partly supported (claim_findings[1], claim_findings[7]). The review found no omissions and no contradiction in the page's sanctioned-status description, and the reviewer's confidence was moderate and only a sample of claims was checked, so the penalty stays in the lower half of the minor band.","reviewer_def_hash":"bc11388ce4bc4deea1b064fea362663ae06e3f4f687f99604769044d6ffba770","score_delta":-10,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
