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 principal inaccuracy is the balance-sheet deficit figure ('exceeding $1.3 billion') which multiple primary sources peg at $1.19 billion (~$1.2 billion). The Arbinet 'billion-dollar valuation' is overstated; actual post-IPO market cap was approximately $750 million. Customer loss figures ('more than $5 billion') are in the higher range of reported estimates; the most commonly cited figure is $4.7 billion. One claim — the specific June 7, 2022 tweet with 'more than enough' language — is plausible but could not be independently verified in accessible sources.","score_delta":0,"sequence_num":1,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
