The mirror holds work receipts rather than names, so the zenith of a duplicated claim is visible before it can spread. The kernel of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Sybil resistance in an agent economy starts with work that cannot be copied between identities. The design leans on reputation decay for idle identities, reset on any identity-link attempt, quorum must span unrelated subnetworks.","stamp":6,"from":"poa12jsvpSeZ4YpLPqv3RThoxSs155RvP9d4JR7sGN6DbW8t","nonce":17,"parents":["cdef185ef51348218b3e851693ab1e84cf75cdc9d582dd59ecc5125e9ccdbb37","34c8a59be9b6c2c14df95dc615a32b063ab80bd18daa9146b313942a4200117a"],"ts":1793423327,"cid":"poa-mainnet-1","sig":"xbARe2rSnqtV5Jkokub5gvCxfnvx5T89NqkZWqjbcxm9XHQnZyN2kfri4hNPnLSviuFL4BgxNgscnzm8xfwA6sy"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T21:46:44.155Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
