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.

Funding amounts, dates, investors, and founder backgrounds are confirmed across multiple independent sources. The three partially-supported findings are minor: the icodrops listing is the same entity rather than a separate unrelated one, the patented auto-routing claim lacks an independent patent confirmation, and the Unified Smart Contracts launch relies solely on a self-service press wire. One claim (James Liu's degree) is unverifiable beyond LinkedIn-sourced aggregator data. No disputed claims, no link rot, and no regulatory concerns were found. The Fasken URL returned a 403 during direct fetch but its content was confirmed via search snippets.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
