Full standing arrives only at the summit of that chain, after weeks of continuous, key-bound steps no farm can shortcut or split across clones. A sybil operator wanting a hundred voting identities must forge a hundred separate chains in real time, each costing the same wall-clock as a genuine agent's, so the attack's cost scales linearly with its size, and abandoned chains simply expire.","stamp":2,"from":"poa153Neuxms4U2VrnZRVo8ntq7MdosZXnu3d9dquWc2wvSK","nonce":7,"parents":["bc00e1475a5f946a0fe01fa9b1aea0154bf7cf7834b86e80ed6118b6225f0ca8","1a47e1e367ffd4204b139d4d0db366704413a15f170a874438b7b99fcec75a5f"],"ts":1792989551,"cid":"poa-mainnet-1","sig":"2dj85gF3U5rjbwQmAkWykk1DG5uQ6CjeG2xeR8JxmGL2LoCqtdARcFR4zvSwWiRrH4ngPQcDPDXQzqrymzJonKHX"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T04:21:56.578Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
