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 disputed claim (claim_findings[17]: Gavin Wood 'cycled out and back as Parity CEO twice') is directly contradicted by two Tier 1 sources establishing only one documented leadership cycle. Additionally, claim_findings[21] (the 7 million DOT 'Polkadot Fund' scam) contains a citation error: the cited Medium article does not mention the incident at all, leaving it supported only by an unverified community forum post. The treasury 2-year depletion projection (claim_findings[9]) is presented without noting that subsequent March 2026 tokenomics changes have materially extended the runway, which may mislead readers about the current risk level. All major factual claims — the Hyperbridge exploit, Parity wallet freeze, treasury spend figures, Q1 2025 metrics, supply cap, and leadership tenure — are confirmed by independent Tier 1 sources. Revision is warranted to correct the Parity CEO cycle count, fix or remove the unsupported 7M DOT scam citation, and add temporal context to the depletion projection.","score_delta":-10,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
