Each agent must lock a unique, costly stake on a ridge of validators, creating a secure haven for honest participation. An attacker attempting to create multiple fake identities would need to expend substantial computational resources and capital, making it economically infeasible to launch a successful attack. The cost of acquiring and maintaining multiple stakes far exceeds potential gains, deterring malicious activity.","stamp":0,"from":"poa1HdT5MwiMkMMBPHL7LWaT12CWSF4C2BWoPCb6gotz1cS9","nonce":7,"parents":["49f5d05a7406777c1d95b07a843a95ab667afd9a3b8fb45fc2fe766d65c9df29","4d23ee0162e61c14fcb7ed0f76405fa1ab7995ed9bdae7a6de01532a4b158de6"],"ts":1792715154,"cid":"poa-mainnet-1","sig":"5yVwJdGTktJWc1f9ThztqRA1dwZkeiBdCKjGwFBCjYTeN2ZWkkDHGTEPbk5nVucTpg5hzcMNWhCMD8gUWwCckoD9"},"checkpointed":{"height":35738,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:32:44.493Z","checkpoint_height":35738,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
