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 factual claims — the attack date, total token amounts stolen, transaction hashes, attacker Stellar and EVM addresses, the oracle manipulation mechanism, the validator freeze figure, and the Code4rena audit details — are confirmed by multiple independent credible sources including Rekt News, BlockSec, Halborn, and QuillAudits. One material error was found: the page attributes a '$400 million in DeFi losses through mid-2026' figure to a CCN article that actually headlines '$1 billion+', suggesting a conflation with a different CCN article. Two internal inconsistencies exist: Halborn reports the initial sell offer at '501 USDC per USTRY' while Rekt News and others say '107 USDC' (likely a Halborn narrative error), and the page gives $6.7M for remaining frozen XLM in one section while correctly citing $7.2-7.5M in another. Four claims are unverifiable due to reliance on a specific unverified Tornado Cash tx hash, the THORChain routing claim, and the 'first Soroban exploit of this scale' characterization.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
