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.

Core facts about the exploit mechanics, attribution, financial impact, legal proceedings, and recovery efforts are confirmed by primary sources including Chainalysis, TRM Labs, Aave Governance Forum, LayerZero's own statements, and multiple Tier 1 and Tier 2 news outlets. Minor findings include a slight overstatement of pre-exploit TVL ('over $2 billion' vs independently-sourced ~$1.7 billion), a possible misattribution of the circuit breaker finding to Halborn rather than OpenZeppelin, and a disputed launch date (November vs December 2023 for user deposits). The investigation's most significant contested claim — that LayerZero personnel explicitly approved the 1-of-1 configuration — is reported as KelpDAO's allegation but cannot be independently verified from available sources, which is appropriate framing.","score_delta":0,"sequence_num":1,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
