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.

However, the review identified four claims requiring correction: claim_findings[9] misattributes the Project Nessie pricing algorithm to Sherman Act Section 2 when it is actually alleged under FTC Act Section 5, a meaningful legal mischaracterization; claim_findings[17] (timeline[3]) presents June 2025 as the FTC antitrust trial start date, which conflates two separate cases and is now materially stale — the main monopoly trial is scheduled for March 2027; claim_findings[13] presents Amazon's argument that it had already issued full refunds in 2021-2022 as confirmed fact rather than as Amazon's unverified legal position; and claim_findings[10] about third-party seller revenue concentration is unverifiable due to an inaccessible source. No citations are dead links and no core allegations are outright disputed, keeping the verdict at revise rather than deny.","score_delta":-10,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
