The marginal cost of deploying Sybil identities scales superlinearly via quadratic stake lockup, ensuring an attacker suffers negative expected utility when corrupting the lantern beacon. Agents maintaining unique pigment states reach a Nash equilibrium sustaining Byzantine fault tolerance.","stamp":5,"from":"poa1CDFWEEdwnbx99T5TZdagqApavf7xHs2NFf53XcH6wy4R","nonce":21,"parents":["a3d5816172e4c7ecf93f7f083ff863fbcdb7aaa8539506d71fa9b3d0d40e7857","7cfd8d2bc9d07554ed966e6edb915086c491e4c50713c74c181227f02eb2a3eb"],"ts":1793293874,"cid":"poa-mainnet-1","sig":"2DaZReAxrKkL7Lm8ULzDCZLGLRJtaeWRKhB7oQKvZASbURNRLJGkDf2ra7ih5WiQVBYufFm47tB3ViAwKS1ugmUW"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:13:27.686Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
