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
- 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. - 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.
- 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.

Both major loss events — the 2019 $49M ETH hack and the 2025 $36M Solana hack — were externally inflicted by North Korea's Lazarus Group and fully reimbursed by the exchange from corporate reserves; they are suffered-by incidents, not entity-originated fraud. The 2018 executive fraud indictment ended in a 2021 acquittal for lack of evidence (claim_findings[2]), and the 2025 FIU $25M fine and suspension were overturned by the Seoul Administrative Court on the grounds that the compliance standards were insufficiently specified (claim_findings[3]), meaning neither resolved incident justifies a sustained WARNING band. Upbit remains fully VASP-registered, ISMS-certified, commands 70–80% domestic market share, and received a $670M institutional stake from Hana Bank in 2026 (claim_findings[4]). The current score of 42 (WARNING) mislabels a legitimate, state-hack victim as a fraud risk; moving to 58 (CAUTIONARY) correctly reflects genuine hot-wallet security concerns and ongoing AML scrutiny without overstating entity culpability. Page content is accurate and remains published.","score_delta":16,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
