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.

The primary disputed finding is the stated all-time high of ~$0.028, which contradicts CoinMarketCap's recorded ATH of $0.04254; the derived 25-32% post-exploit decline calculation is therefore also inaccurate. Several claims are partially supported because they rely on single-source attribution (e.g., the 13 ETH + 300 ZEC bounty breakdown), or carry editorial framing ('legally structured') that overstates the specificity of what TAC publicly disclosed. The page has significant coverage gaps around on-chain evidence, official TAC primary sources, and post-hack follow-up on the compensation and audit.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
