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.

However, claim_findings[16] (Mark Scott's sentencing date) contains a clear factual error: the timeline states April 4, 2023 when independent sources confirm January 25, 2024. claim_findings[3] ('collapsed in 2017') understates that operations continued under Konstantin Ignatov until March 2019. claim_findings[5] (225,500 euros maximum package price) is sourced to an industry blog rather than primary documentation. These errors, coupled with medium-priority coverage gaps (Konstantin Ignatov's final sentencing, victim harm by geography), warrant revision to correct dates and expand context on scheme duration and loss distribution.","score_delta":-20,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
