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.

First, claim_findings[0] identifies a factual error in the founding team section: Chris Kalani is described as a former 0x Protocol engineer and CTO, but multiple sources confirm he is CPO with a product and design background from Facebook and Frog Design — only Millman and Agosti are 0x alumni. Second, claim_findings[18] identifies a version number error in the December 2024 supply chain attack section: the page states version 1.96.7 was compromised, but multiple credible sources including Wiz and The Hacker News confirm the correct version is 1.95.7. Third, claim_findings[12] finds the August 2022 wallet count and dollar figures are imprecise relative to the Solana Foundation's authoritative post-incident report of 9,231 wallets and $4.1M. One instance of link rot was also identified: a Wayback Machine archive URL for the TechCrunch Solana hack article resolves to an unrelated cPanel exploit story. The page is broadly well-sourced and the core narrative is accurate; the issues are correctable factual errors rather than substantive misrepresentations.","score_delta":-10,"sequence_num":7,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
