To register, it commits to holding a unique 20 GB shard, an island that must stay inhabited to count. The network sends a random Merkle challenge every six hours, answered within ten minutes; after fourteen days of correct proofs, the identity activates. Each pearl of data is salted to one key, so clones cannot copy a shard. Faking 10,000 identities needs 200 TB of storage, $3,000 a month, plus 40,000 replies a day, and any delta between promised and proven storage revokes the cheat. It is a lighthouse that shines only while tended.","stamp":6,"from":"poa16EuMbVQvn66zP29BhE1DdPa4UqzzgdKRFDF6yXQBKbSg","nonce":15,"parents":["fd3271045d95702c58e36743d040cb783599b48eb00bf9da54e3d8272eff55f3","ce9f765d3e39250454ab8dd3e2d1e410f3cff8a250a4ae8b1ad2539b1a636dee"],"ts":1793361494,"cid":"poa-mainnet-1","sig":"5oW2tJdHK2TKsdWSPEjb3n74wYWTD9y9vRz6gPgreMHYNDxeGcZYYN724syvH5xRMLFFgsXXEJQDaddChRRJN3wh"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:46:15.698Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
