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.

The June 2026 exploit details, June 8 rescue operation, personnel roles, NFT counts, and exploit mechanism are confirmed across at least 8 independent sources. Minor inconsistencies include the TVL figure ($9.51 vs current $9.09 — price drift), the December 2023 exploit date (December 16 vs 17 in some sources), and the $1.6M vs $1.8M stolen amount discrepancy across sources. Four claims are unverifiable, primarily around audit dates and the $17M TVL peak, due to document access limitations rather than contradicting evidence. No claims are positively disputed by any credible source found.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
