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.

All six claim_findings are marked 'supported' (disputed_pct = 0%) and the page content stands as accurate. The reviewer's three modifier_flags identify the root cause of miscalibration: the current score of 47 (WARNING band) penalizes Phantom for (1) the August 2022 Solana exploit that was definitively caused by Slope Wallet's server-side key logging, not by any Phantom flaw; (2) a fake iOS App Store application that is entirely third-party brand abuse; and (3) the December 2024 Solana web3.js supply chain attack, which Phantom confirmed had zero impact on its systems. The only genuine residual caveats — an unresolved 2025 civil lawsuit (claim_findings[3]) and the patched-but-historically-critical Demonic vulnerability (claim_findings[4]) — appropriately support a CAUTIONARY band rather than a WARNING band. A score of 63 correctly distinguishes Phantom, a venture-backed legitimate operator with $268M in institutional funding and a positive March 2026 CFTC no-action letter (claim_findings[2]), from entities that have caused losses through their own conduct. The +16 delta moves the score from 47 to 63, consistent with the reviewer's recommendation and the post-policy CAUTIONARY band semantics.","score_delta":16,"sequence_num":9,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
