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, three factual inaccuracies require correction: (1) the balance-sheet deficit is stated as 'exceeding $1.3 billion' but court filings confirm $1.19 billion; (2) Arbinet's post-IPO market cap is misstated as 'billion-dollar valuation' when it was approximately $750 million; (3) customer losses are overstated at 'more than $5 billion' when the standard figure is $4.7 billion. One claim (June 7, 2022 tweet) is unverifiable.
