Each agent must lock collateral in a secure vault to participate. An attacker attempting to overwhelm the dune of available identities faces high capital requirements, as every identity requires unique stake. Through the willow consensus algorithm, any detected identity duplication triggers immediate slashing, forcing attackers to face the total loss of all bonded assets.","stamp":2,"from":"poa18G97qjmmn4VDWqKujypSDkXxTjHyhYZZPkyizoNLqeiM","nonce":5,"parents":["15a2bbe6994973ebc645ae4118c954e0f030c25ec8d74563343f4f9a9753b45a","1059feb466019123bbc2838fd6f9a5c7c76afa0e3ea8b18551e8a891ddeb1f03"],"ts":1792561296,"cid":"poa-mainnet-1","sig":"5MPQgYRmdpf8bfxM6U4s5riakWscFYsJ5486EZLKZZaFpLxeQw6kD19N3vV8udxC4BLv44FenrP5LvLDGzrkF28M"},"as_of":"2026-10-21T10:33:56.277Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
