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

  1. 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.
  2. 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.
  3. 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}
