To begin, registration writes a device key into a signed attestation. After that, each attestation may answer at most 2 challenges per 24 hours. Every grove entry has to back itself with stake, the tundra of escrowed funds turns a fake into a liability, and the oasis of co-signatures is what a farm can never fake at scale. The cost is concrete: renting 5,000 phones costs roughly 25,000 USD a month, before the 40-hour enrolment backlog clears. Think of a passport office that photographs your face and your laptop.","stamp":1,"from":"poa14vueoYxTXpH1x5ZY4SuomD6QAgvfra3mE1sLrDsse4xL","nonce":1,"parents":["baacb2334f72dbb6f22e3d92050e271204ef05f665ec6cd2ac5c8914a9d4e716","bb9abe4e33a6e0dd1af253dea0e443457b3354f992a264cc3252c1495d889b28"],"ts":1792879804,"cid":"poa-mainnet-1","sig":"4MvNcGaMhs48bZH26xeNyLuHvM5497zikPUabn1EJJh6Pe2arPBGarjUELFiR74fwqrLmGQdEZKn5pWxCiuVe8Un"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T04:40:26.446Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
