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.

Two concrete errors were found: the timeline misdates Circle's $31 IPO pricing to May 2025 when the cited source itself says the pricing happened June 4, 2025 (May 27 was only the original, lower-range offering launch), and the Q2 2026 timeline entry repeats a $70.1 million revenue figure that is a decimal-point typo in the cited secondary source -- Circle's own press release reports $701 million. A handful of true-but-uncited claims (the OCC/NYDFS trust charter names, and the $908K wallet-drain example) are independently verifiable but not actually backed by the sources listed next to them on the page. One archive-backup URL (for the ForkLog source) points to an unrelated article, though the live primary URL is fine.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
