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 clearly disputed claim is the Miami Heat arena naming-rights cost, stated as approximately $205 million on the page when multiple credible sources consistently report the contract value as $135 million over 19 years. Three claims are partially supported due to minor imprecision in paraphrasing (Ray's quote, the Bankman-Fried indictment count transitioning from 8 to 7, and the slight compression of the timeline between SBF leaving Jane Street and founding Alameda). No link rot was identified among cited regulatory sources; news article links were not all individually fetched but search results confirm the underlying facts.","score_delta":0,"sequence_num":1,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
