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 issues require correction: (1) claim_findings[9] identifies a year-labeling error in which an October 2024 timeline entry is sourced from a Yahoo Finance article published October 31, 2025 — the dates do not match; (2) claim_findings[2] and claim_findings[13] both cite a single Tier 3 aggregator for the 60-70% profitability reduction and 60% complaint reduction figures, with no traceable primary methodology behind either number; and (3) coverage_gaps[1] flags that Jito Labs and the Jito Foundation were fully dismissed from the SDNY class-action on September 30, 2025, a material development not reflected in the summary or timeline. These issues do not undermine the page's core evidentiary record but require targeted corrections before the page accurately represents current litigation posture and timeline chronology.","score_delta":-12,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
