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.

This single factual error appears in two locations (sections[0] and the 2019 timeline entry), amplifying its impact. A high-priority coverage gap also flags that the Sales History section groups the Casa Batlló Christie's sale (May 2022) alongside 2025 events without a clear date attribution, creating a misleading temporal impression documented in claim_findings[15]. Additional minor issues include a slight misquotation of the Lancelin 'digital cathedrals' line (claim_findings[23]) and imprecise labeling of the 2025 TIME100 AI Impact Award. No core allegations about fraud, regulatory status, or auction provenance are disputed.","score_delta":-8,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
