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 major factual claims — the arrest, charges, scheme structure, financial scale, regulatory warnings, asset seizures, and the political Alvise Pérez connection — are confirmed by credible independent sources including Tier 1 outlets (Euronews, CNMV registry). One material factual error exists: the co-defendant 'Daniel Alcázar Jiménez' should be 'David Alcázar Jiménez' per multiple Spanish legal press sources, and the co-defendants list omits Juan Carlos Romillo Iriarte (Álvaro's uncle) who is named in the formal indictment. The Block article cited as a source returns HTTP 403. Two claims (age ~42, cryptocurrency mixing services) are unverifiable from available sources. The page also merits updates to reflect the Proelucyon LLC corporate linkage identified in CNMV/FSMA documents and the 2026 court proceedings showing only 464 formally recognized victim claims to date.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
