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.

In late 2025, Helius launched Gatekeeper, an in-house Rust-based edge gateway replacing Cloudflare in the critical request path to reduce latency by tens to hundreds of milliseconds. The company also operates Solana validators and offers Validator-as-a-Service (VaaS) for white-label enterprise deployments.

Specific documented incidents include elevated HTTP 530 errors on api.helius.xyz and api-mainnet.helius-rpc.com from a U.S. East routing issue caused by a Cloudflare point-of-presence failure in April 2026, and a Frankfurt node timeout on the Gatekeeper Beta endpoint on April 25, 2026, which lasted approximately 26 minutes before traffic was automatically rerouted to Amsterdam. Helius maintains a public status page and has acknowledged incidents promptly. The introduction of the Gatekeeper edge gateway in 2025 was specifically intended to remove reliance on Cloudflare in the critical path, addressing one identified source of reliability risk.

Mumtaz publicly denied all allegations, stating the claims were 'hallucinated' and characterizing Smith as a harassing disgruntled former employee. No independent corroboration, court filings, regulatory complaints, or third-party witness accounts supporting Smith's allegations have been identified.
