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.

However, the page overstates the certainty of a permanent shutdown: BitMart itself announced on August 21-22, 2026 that it may pursue restructuring and a phased resumption instead of full closure, a development that postdates the page's sources and is not reflected anywhere on the page. A regulatory claim about UK 'lost authorization' mischaracterizes an unauthorized-firm warning as a revoked license, and an industry-statistics claim misattributes a '30 projects folded' figure to CoinDesk when CoinDesk's own reporting cites substantially larger figures (63, then 100+).","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
