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.

Leap Wallet's shutdown is documented across multiple independent sources as a business-sustainability closure (VC contraction, thin wallet-sector margins) with explicit confirmation from a cited source that this wave is 'not the disorderly fraud-collapse of Terra or FTX' and that no court filings, regulatory actions, or fraud allegations exist against the company. The page proactively includes this exculpatory framing rather than omitting it. The one elevated-severity claim (phishing risk during migration) is appropriately hedged as speculative risk, not a confirmed incident, and the page explicitly states no verified large-scale phishing campaign has been identified.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
