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.

is a centralized cryptocurrency exchange founded in 2017 by Sheldon Xia, incorporated in the Cayman Islands and operated by Bachi.Tech Corporation.

The exchange has subsequently faced an FTC investigation, a UK FCA unauthorized-firm warning, an alleged 2025 data breach affecting 1.2 million users, recurring user complaints about frozen withdrawals, and its platform was used as a venue for DOJ-charged wash-trading schemes targeting retail investors.","timeline":[{"date":"2017-10-01","event":"BitMart founded by Sheldon Xia; incorporated in the Cayman Islands.","source":""},{"date":"2018-01-01","event":"BitMart begins public operations and registers with FinCEN as a Money Services Business.","source":""},{"date":"2019-08-01","event":"BitMart raises Pre-A funding round led by Fenbushi Capital.","source":""},{"date":"2021-11-01","event":"BitMart completes Series B funding round of $13.7 million at a $300 million valuation, led by Alexander Capital Ventures.","source":""},{"date":"2021-12-04","event":"PeckShield publicly identifies an ongoing hack draining BitMart hot wallets; approximately $196 million in customer funds stolen via stolen private key.
