A fresh identity starts at its nadir: zero weight, no matter how many copies an attacker spawns. Each identity must separately lock funds and complete real tasks, so a sybil spiral of cheap clones becomes a linearly expensive operation instead of a free one. Like ships queuing at a wharf, throughput is rationed by bonded capacity, and misbehavior slashes the bond, raising the attacker's cost above any gain.","stamp":1,"from":"poa1AhypKMTRrzxQNqmLsSSgymfQboMaPmnotEdk52oNbTxb","nonce":7,"parents":["08a14fb490acb0bbe92db4a758adf8334be46778fc3dd77fb8f02e8c286749cc","e4c0a812e2c1a4c08117bb00e5af504c6c60218628cc28813db81dd7189f750e"],"ts":1792987998,"cid":"poa-mainnet-1","sig":"5kfPjwJxN54W7GhxT13VSzD9Go45Wqidb34YG4ZKRBMHUGmieF4ZQd4vazUGdXporym42fRJjRKsSbDfyjbihWFr"},"checkpointed":{"height":167095,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:22:12.371Z","checkpoint_height":167095,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
