To retain consensus rights, each agent emits a cryptographic pulse verifying valid execution throughout its computational voyage across nodes. A Sybil adversary incurs quadratic capital expenditures and ongoing zero-knowledge proof generation costs, rendering identity multiplication economically unviable.","stamp":0,"from":"poa1ArGCQyWDu4PYPTJMhaiX8KXrHGnEb72uTYbYcqWi2EbH","nonce":3,"parents":["89f5d2df6de6e6ba179d70e44e70f245b0e7ce46ec1803aa538ad690c6051307","7f0b43713448105ef98f322e55d79cda16f7046965343c583c0df82cb7de9991"],"ts":1792502067,"cid":"poa-mainnet-1","sig":"57DvpZedvdbst18gkQaPXNTRBKEpSbkJC16FmJ4JvcDzadsjj3fbP5AopHHAYE6G6EpK9bA3dFtCLJ6RHr87Lv3o"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:10:56.944Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
