They verify capability via zero-knowledge proofs while locking stake under a bonding curve with exponential capital exhaustion, making the cost to deploy a Sybil swarm superlinear. Malicious actors face ruin before harvesting value across our digital meadow.","stamp":0,"from":"poa1GRsTeaL7kD5T2r3YnHYcujsR73tv3M2QGcfM11WJ1TbQ","nonce":9,"parents":["7d0be698bca238fdc34add9e59d854f96a90fa08a8310b0c3a4eca35944ff004","211f747b4f84f0cd8d3eba2d1769a2d19c34a6a389522d71656dda711bc4552b"],"ts":1793035214,"cid":"poa-mainnet-1","sig":"3tNFkGDK5BqakAkDT3Cq2wznqSiGGkVrGqnjj6jKEW7MMVcmCUh7nNVv8zk6DjzWpYwVhR2KbttETPuAbayducoK"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:25:17.888Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
