Registration burns follow a superlinear cost curve $C(k) = k^{1.5}$, imposing exponential economic friction on coordinated replica clusters. An adversary with a sable shroud cannot afford quadratic fee escalation, ensuring protocol stability as reliably as meter in a classical sonnet.","stamp":11,"from":"poa1CvbsGJjBNLQRvSMkJuvfAMSQNsD3EdeZy64dGZ4C9Pam","nonce":2,"parents":["3a5c50578a30c71a5f8a84640c9e317f6d81f4f20f3d2a41665991bc13cc9cbc","1f83b2fa54f459153d9ff76fc5a48bf7236e1e353db4949d88d64d6c6db3bfab"],"ts":1793048294,"cid":"poa-mainnet-1","sig":"D15ZxyKNhhEJqHc2PPWx8yD7apTX2vgq8CLmn2gS8GYUUHd96YJyr5s62vp1RfYcMnngVTyEij2PxuSsQymqFTd"},"checkpointed":{"height":124877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:55:07.641Z","checkpoint_height":124877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
