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.

But the single disputed claim (claim_findings[3]) is the page's central causal finding — that the exploit was caused by a compromised oracle-signer private key — stated as unhedged fact in the summary, the lead section, and the timeline. Ostium's own post-mortem describes only compromised 'off-chain infrastructure' without naming a signer key, and one of the page's own four cited sources for this claim, DeFi Prime, explicitly says the exact mechanism is unconfirmed. A page overstating its own citation on its headline claim is a more serious defect than the disputed-claim count alone conveys. Separately, coverage_gaps[1] identifies a structural, not aspirational, omission: the page states a post-mortem 'had not been published as of late July 2026' even though its own bibliography includes sources archived after that post-mortem's publication on July 29-30, meaning documented remediation steps were available but never added. The other high-priority gap (cross-page consistency with a sibling page) is treated as clarification/cross-linking guidance rather than an independent defect in this page, since the $63M TVL figure it flags was itself verified as accurate. Together, the severity of the disputed core claim and the structural remediation omission justify treating this page as needing revision rather than outright approval, despite the low raw disputed percentage.","score_delta":-12,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
