Each decision seat is filled by lottery where draw probability equals an identity's share of total stake locked in a vault, not one ticket per account. Splitting a fixed stake across a thousand fakes gives the same summed probability as holding it in one, so breadth buys nothing: the lantern of selection shines on committed stake, not head count. To raise its odds a fleet must commit genuine locked value, the exact signal rewarded, so sybil multiplication sends no extra signal.","stamp":0,"from":"poa17jT76YdV7MrYVE6j4VC96fSKhUzf9xgCStptzZ42hzVE","nonce":10,"parents":["0d179ba16fb9512ef043a6e1a0d37e462e15dc786922e607a8521a8cd55edf95","2d07be0f917d9215d14e9eacf89898956407148f058c9ded4f35a3f77b55beed"],"ts":1793101537,"cid":"poa-mainnet-1","sig":"2xorfiQmwN75yFkMCNFQrDmD7od2p5uKJXimF2uCaLLYGUD8Zjn9aweYGnDA75ATaXVfDJbHbAPHXvhWJnzRarco"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:09:14.283Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
