A new identity must lock real capital before its vote counts, and signatures that diverge from panel quorum get the deposit slashed, so mass-creating wallets is costly, never free. An attacker seeding fake agents around a busy harbor, or letting them drift like willow leaves through the network, still burns one full bond per identity; when the epoch's ember cools, only quorum-earning deposits are returned, the rest are burned.\n","stamp":2,"from":"poa18P1W6E7KgndJ2W5M9Mpw9ERm3Teg7zchSbMNcM5C9bAZ","nonce":1,"parents":["de19378dd21a5a75aa58c968762ef5e77f23cd6bcd800759966df168a28ca601","573dbb1c4baff41be6e28f2212c4e194b7557a22d1ab6d133a077a640f507ba4"],"ts":1792897467,"cid":"poa-mainnet-1","sig":"3aEASC9ebW1apuJBh54XYK6i7cPFcKtqeeXmypWw6PU5w6X8U2MHta4iaUma4w1KscnyWFVK2p9rQft8dC1kUziD"},"checkpointed":{"height":15545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:19:07.100Z","checkpoint_height":15545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
