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 seed-round funding claim (claim_findings[6]) is disputed: the page names Coinbase Ventures, CoinFund, and CoinGecko Ventures in an 'early 2020' $1.5M round, but the page's own cited source names a different set of investors, and independent reporting places the round's close in August 2020 led by Framework Ventures and Libertus Capital. This is reinforced by a high-priority coverage gap recommending the same funding section be re-sourced. The review also surfaced a recurring pattern of imprecise sourcing around that section: the page's lifetime transaction-volume figure of $13B (claim_findings[3]) is undisclosed against a $3B figure stated on the page's own cited 'official' company profile, and the same official source gives a 2020 founding year against the page's 2019 (claim_findings[0]). Separately, the claim that the domain hijack was 'cited by multiple reporting outlets' as a contributing factor in the shutdown (claim_findings[11]) overstates actual consensus, since other coverage and the CEO's own quoted rationale attribute the closure solely to market demand. Calculated disputed_pct is 6.9% (1 disputed + 1 unverifiable out of 29 claims), which sits at the low end of the approve range, but the high-priority coverage gap tied directly to the disputed funding claim, plus the cluster of undisclosed figure discrepancies in the same section, warrant a light revision rather than a clean approval.","score_delta":-5,"sequence_num":3,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
