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.

Four claims are partially supported: claim_findings[3] incorrectly attributes Jump Crypto to the 2024 Series A when it was a 2022 Coral investor; claim_findings[15] overstates the FTX EU acquisition completion as 'January 2025' when the underlying deal closed in June 2024; claim_findings[16] misdates the Backpack EU launch as 'mid-2025' when CoinDesk and PR Newswire confirm September 8, 2025; and claim_findings[16] also overstates Backpack EU as the 'only' regulated perpetual futures provider when the CEO himself acknowledged Kraken as a co-provider. These are peripheral details — none undermine the page's core risk narrative — and the reviewer's confidence is high at 0.88. A small score reduction reflects the four correctible inaccuracies. One high-priority coverage gap (FTX EU estate dispute resolution outcome) remains open and warrants future expansion but does not affect the current verdict.","score_delta":-3,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
