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.

However, the page is materially out of date: it presents the 2025 Rujira Alliance merger as an ongoing arrangement, but the review found Rujira's own documentation states Levana's alliance membership was not renewed and its isolated Perps product is being discontinued (claim_findings[5], coverage_gaps[1]) — a development entirely absent from the page. Separately, all six page sections have empty body text, leaving most of the entity's claim surface unreviewable (coverage_gaps[0]). One minor timeline claim about a Gate.io trading halt now rests on a dead citation with no independent corroboration (claim_findings[16]). None of these issues fall into the disputed-claims count, but the two high-priority coverage gaps are sufficient under review policy to require revision even when no claim is actively disputed.","score_delta":-10,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
