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.

The one clear factual error involves the March 2024 Montenegro Court of Appeals decision — the page incorrectly states the court reversed a prior ruling and ordered proceedings restarted, when the court actually rejected Kwon's appeal and upheld extradition to South Korea. However, this local error does not affect the page's core narrative, as the subsequent Justice Minister decision correctly approves US extradition (December 27, 2024). All major legal outcomes—the SEC civil verdict ($4.47B), guilty plea (August 2025), and sentencing (15 years)—are accurately reported and corroborated by Tier 1 sources. No link rot or stale findings were identified. Five coverage gaps (South Korean proceedings, asset dissipation, Terraform bankruptcy, Terra 2.0 status, and 2026 pardon rumors) suggest constructive expansion rather than denial.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
