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, the page contains one clear two-year date error that repeats in both prose and the timeline: it states the 0x v4 governance vote was approved in January 2023, when multiple sources including 0x's own blog place it in January 2021 (the '2,300+ holders' figure is itself accurate for that 2021 vote). It also overstates the ICO's backer/address count (13,000+ vs. the consistently reported ~12,000), narrows its own cited source's mid-2025 ZRX price range ($0.21-$0.25 vs. the source's stated $0.20-$0.30), and rests several Matcha-scale claims (130 sources, 16 chains, top-three ranking) on a now-dead DEXTools source that could not be independently corroborated. The April 2021 $2.40 near-ATH figure is supported by its cited source but conflicts with a dated contemporaneous price snapshot and with every price aggregator consulted, none of which records any 2021 peak at all.","score_delta":0,"sequence_num":5,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
