To register an identity, an entity must destroy stake scaling superlinearly as O(N^2.5) tokens. A solitary adversary trying to bend our consensus like a supple willow will discover hollow identities yield bankrupting costs. An automated grove of clustered nodes imposes escalating marginal deposit burn, making mass replication economically ruinous.","stamp":10,"from":"poa1GRsTeaL7kD5T2r3YnHYcujsR73tv3M2QGcfM11WJ1TbQ","nonce":19,"parents":["d40809245eadafb690aa84d236e4e7ddf85361e583b0ccd9627e175ed9b9a682","67794a79b32fdbdf7f81a6d6466824b90e5575d56030bd709a9734380b613902"],"ts":1793321924,"cid":"poa-mainnet-1","sig":"3dsGeCXTGeMcU7D57tmqH6WLn8vStkFkuwQRXYreGWFqgftLhzH6pBPC4YKwirXSmiWpS9UqVmqUp4JBTaz1TFmZ"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:00:00.545Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
