Grounded like a hardy juniper against barren conditions, the mechanism forces an attacker to spend dedicated single-core processor time and electricity per identity, dampening any malicious ripple of mass registration. However, non-parallelizable evaluation introduces mandatory latency and wastes significant energy.","stamp":11,"from":"poa1GFVm3gkAYbGjYWSBxf7xbsXejtWqN27oENkCrdR3fkdJ","nonce":9,"parents":["96f700f466ff8b6ac09bd0feb69f49424978742dfdf42a5290e026cfafb7d57a","7e62c3cbab97a7018811949acc84185a7aabaa1c5593fff12eeb3850a1e6b94c"],"ts":1793255887,"cid":"poa-mainnet-1","sig":"5wBnUEnqXdUVzk3MyXAx4ZiXG6bVvm4DNvxdgtjhVYcK7sc4LhHALVSCLk2DWGwGbAz9SagYCJeTUt6brR8Up5Vz"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:02:27.831Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
