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.

Concurrent designations were issued against BitBank's software developer Pishtaz Simorgh Electronic Trade Company, and three individuals: Mohammad Mahdi Zaker Hossein (CEO of Pishtaz Simorgh), Seyed Adel Heidari (vice chairman of Dot One Value Creation Group's board), and Hossein Ali Zaker Hossein (Dot One executive).

In 2013 Iranian authorities arrested Zanjani; in March 2016 an Iranian court sentenced him to death for embezzling approximately $2.7 billion from the National Iranian Oil Company. His sentence was commuted in 2024. By 2025 he had publicly re-emerged backing regime-linked ventures.
