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 most significant factual error is the Breakpoint 2025 timeline date (marked September 2025, actual date December 11-13, 2025). The claim that Anas Khader presented at all three Breakpoint conferences (2023, 2024, 2025) is incorrect — Zoheb Shahzan presented at Breakpoint 2023. The 500x leverage claim is technically accurate only for the crypto asset class and overstates the typical platform experience (100x is the common public-facing figure). Price/TVL/volume figures are broadly current and accurate as of review date. The cited FLP token doc URL is a 404 (link rot), though the underlying claim is supported by alternative sources.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
