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.

All core allegations — the November 6 arrest under Operation PONEI, the Audiencia Nacional bail denial, the Ponzi scheme structure, the CNMV regulatory warning, the political connection to MEP Alvise Pérez, and the major asset seizures — are confirmed by multiple independent sources including Tier 1 outlets (Euronews, Wikipedia, CNMV registry). The four partially_supported findings (claim_findings[7], [8], [22], [24]) are minor: the 20-53% returns range is a reasonable cross-source synthesis with no contradicting figure, the €7M membership fee is arithmetically plausible, the co-defendant name discrepancy ('Daniel' vs 'David' Alcázar Jiménez) and the omission of Juan Carlos Romillo Iriarte from the named list are imprecisions in a supporting detail rather than core allegations, and the Omnia yacht length difference (59m vs 60-62m in registries) is a rounding-level discrepancy. The high-priority coverage gap flagged (on-chain tracing) is an expansion opportunity, not a basis for revision.","score_delta":0,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
