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.

Verdict: over-penalized. Page content is treated as accurate; the trust_score band is miscalibrated. Cardano (ADA) is a legitimate, peer-reviewed, institutionally recognized blockchain platform operated by a Swiss non-profit foundation (Cardano Foundation), a research engineering company (IOG/Input Output Global), and a commercial entity (EMURGO). Every single incident in the page's 12-entry timeline describes third-party attackers — YouTube channel hijackers, North Korean state hackers targeting Atomic Wallet, NFT phishing operators, fake app developers, and phishing email campaigns — exploiting Cardano's brand and user base. The page's own summary uses language that presupposes Cardano is a victim (\"holders encounter multiple threat vectors\"). There is no evidence of fraud, exit scam, Ponzi mechanics, or any regulatory enforcement action against Cardano itself; the fake SEC lawsuit claim cited in the timeline was fabricated by the attacker who breached the Foundation's X account, not by Cardano. Independent verification confirms that CME Group launched ADA futures in February 2026, multiple major asset managers have filed for spot ADA ETFs, ADA was included in the U.S. national digital asset reserve, and the SEC has not taken enforcement action against Cardano. Under the post-policy band semantics, a score of 32 (WARNING) is appropriate only for entities with elevated fraud/loss risk or unresolved severe incidents — Cardano meets neither criterion. The incidents on the page are precisely the kind of scam-ecosystem activity that affects every major cryptocurrency (Bitcoin, Ethereum, Solana all have analogous pages of third-party impersonation scams) and should be documented as CAUTIONARY consumer-awareness notes, not WARNING-band risk signals. A score of 72 (VERIFIED) is appropriate: legitimate with well-documented third-party threat vectors that users should know about, but no unresolved incidents attributable to the entity itself.","score_delta":0,"sequence_num":4,"submission_content_hash":null,"submission_id":null,"submission_kind":null,"submission_valence":null,"v":1}
