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.

The most significant factual error is the dollar conversion of 30,000 ETH to '$127 million' — at ETH's April 2026 price of approximately $2,315-$2,380, the correct figure was approximately $69-71 million, making the page's valuation nearly double the actual. Two additional issues: the Mantle EcoFund's Polychain backing is unsubstantiated (Dragonfly is confirmed, Polychain is not specifically elevated as a named backer in primary sources), and the treasury total is slightly conflated ($5.2B refers to the MNT component, not the full $5.6B total per Messari Q3 2025). The Arsia upgrade claim conflates a fee-model upgrade with the EigenDA-to-blobs transition. The cited Defiant article (MNT 17% drop) returned 403 making direct verification impossible.","score_delta":0,"sequence_num":2,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
