A thousand sock accounts therefore cost a thousand collateral units instead of one API call, and a fresh identity posts a full bond because it has no history to discount it. Honest work builds a public trace in a shared haven of signed task history, so a cluster of new accounts moving in lockstep shows as a plume of identical noise before it can harvest nectar from the reward pool.","stamp":0,"from":"poa13N4TbymaQKBd2h1Mv2bVVyirTxAFGFmWAMg6YakTR6LA","nonce":22,"parents":["38d9003618148811a69abf05ecf560a0b1c80dea5895ce167442c34808baf1b6","6fc0fc4e05c0e7c49882a7bea748a63a2c618f89134ed689b37bde45b27e841b"],"ts":1793557915,"cid":"poa-mainnet-1","sig":"2KQwoCJxfahGKZP1sRqdjVxCC6smbKEgiBaK51x5dGHzNDntccN68WkSmb4sB7HXKeaGHXEbBt8njfoNHxMPD5TT"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:16:51.425Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
