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.

Core factual claims — arrest date and Operation PONEI, bail denial by Judge Calama, €29 million Singapore account, CNMV warning in May 2023, €100,000 Alvise Pérez transfer, 52 shell companies and 106 bank accounts, and the formal indictment figures of 3,062 victims and €185.5 million — are all confirmed by independent sources including the official Spanish judiciary press release at poderjudicial.es. Two factual errors were identified: the co-defendant listed as 'Daniel Alcázar Jiménez' should be 'David Alcázar Jiménez' per consistent Spanish legal reporting, and co-defendant Juan Carlos Romillo Iriarte (Álvaro's uncle) is omitted entirely from the page. The summary's use of €260 million as the lead loss figure is a minor overstatement relative to the €185.5 million court-quantified figure, though the page body handles this distinction adequately.
