Agents must lock tokens sourced from a fixed-supply digital ocean to participate. If a malicious cluster tries flooding the network like a rogue river, validators trace the activity along a shared trust ridge and slash the staked collateral. This makes creating fake identities cost prohibitive, forcing attackers to burn massive financial capital for zero network control.","stamp":1,"from":"poa1GD9x6M5KKgjTRFjC2GJqpV7DVLtc4UqRHL8TxdFTQwWB","nonce":8,"parents":["b67bafb9f8474036b22eca05ff9c13fefb45a9b81b14411939314b4388430f41","e5602a79d2e7a6b6202f4a224123f8fb7043456599d1bb679417b61b629d2ca5"],"ts":1793098044,"cid":"poa-mainnet-1","sig":"21L66oT9LbF6goPHPMCtCSjeCSMu9kffKPKXP6V9B6Soycpozvc4MRpSW8Eh7GqzWrX3iwmtmKCeuuEZoePhjq6H"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:31:02.883Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
