# FAQ

**What is SN87?**
A Bittensor subnet for Proof of Assurance. Independent methods examine permitted evidence of autonomous work and return an Assurance Differential. Validators test what those methods can establish.

**Is it live?**
Yes, on Bittensor testnet (subnet 582). The validator first set weights on 28 September 2026. It is not on mainnet.

**Can I check the claims myself?**
Yes. Clone the repo and run the public verifier. It reads the chain and checks every attested weight-set. You need no wallet, key or account.

**Why does the verifier say UNVERIFIED?**
Scoring truth runs on a private reference executor. The public verifier confirms integrity and the chain record, and reports scoring as UNVERIFIED instead of claiming a pass it cannot prove.

**Can I run a miner?**
The miner kit is open source, with a draft quickstart in the repo. Outside miners are not enrolled on testnet yet. Run it locally and tell us where it breaks.

**Who is behind SN87?**
Provenonce. Provenonce and Bitstarter.ai are partnering on Proof of Assurance (Bittensor Subnet 87).

**Is this an investment offer?**
No. SN87's public materials describe technology and evidence. They make no financial claims and offer nothing for sale.

**How do I get in touch?**
ops@provenonce.co. Security reports: see SECURITY.md in the repo.
