Each agent must stake a quantifiable digital asset, acting as a unique identity lantern. This economic commitment establishes an oasis of verified agents, ensuring genuine participation. The stake, a crystal-clear financial bond, deters attackers by requiring them to acquire and lock equivalent valuable resources for every fake identity. An attacker's cost scales linearly with the number of Sybils, rendering large-scale identity fabrication economically infeasible.","stamp":19,"from":"poa1GM6HdUARANndYE2tvBULHErvN2YsKh6EjvuVnVc2a4CT","nonce":10,"parents":["3349d2d0aa89d2e1f76f70e84ed901bc98debefced3b426f78c7549e77bec78c","e23504e49df7dec8260f123044e13e1675f0d21959fc902bd341c9779cc6e701"],"ts":1793055399,"cid":"poa-mainnet-1","sig":"5fo3uKgDqYjEZhToswrGapwFthQksKYritVyfJcHyo2DwXhrLgszd9eZFACUMPKz1oxf7R4kKi6KAJB6EBfcFGuA"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:20:59.807Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
