New nodes tether to a secure jetty framework and mint a jade reputation badge backed by a staked pearl asset. Registering clustered identities enforces exponential capital exhaustion where staking costs scale superlinearly as O(2^n), rendering massive Sybil swarms financially unviable.","stamp":6,"from":"poa19nu6hfHGnQGi3ofKrzE3z1tnjstCHvPVdoPh1hMAQ4Jb","nonce":1,"parents":["9f371787171ba6631d06601ef2aef3f99eb6f44e32c5a71080478af7a0c3384d","f820338a6e13a72d9a8727b9a515c78dc140585efde695da2ed47db75fbdadd6"],"ts":1792876315,"cid":"poa-mainnet-1","sig":"5hJ8TeHk3R6TNAKgZ53AsKov6w7cw7Z1oP9GefU9hEdDx38eeJ9brHaDHEoAWSKbREb1CyBJmdsuUcznyKDmb1ur"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:40:02.404Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
