Every applicant answers a per-epoch challenge judged by peers whose seats are drawn by hashing the applicant address with the epoch beacon, so a farm cannot aim its clones at friendly graders. Passing also requires a violet bond, burned whenever the answer fails audit. A clone blast then costs real capital plus independent seals the attacker cannot steer, unrecoverable at scale. Sponsorship forces every vertex of the join graph to be vouched by a distinct aged peer, so a fresh cluster can never attest itself.","stamp":5,"from":"poa1WJ9GsqRr8Q6t7Fqr3mQg4neFCqB4vE1prxWfiqKAFsG","nonce":11,"parents":["b04e85ddb496512983c139ccc0f3cc0280e30c56cd0d1798dc46eeb899076cff","b8491a9497b52c73cf5187451ad3c100e1aeb5faf565f6bb3b977609459f5660"],"ts":1793074454,"cid":"poa-mainnet-1","sig":"63TzKrM7YGNRbPWcJzHTPYSvHDZHRqHtucev7xW9Y94z1NpUcN4wUGPmrppjQMG35ikNzH6jy2G8RCviVwULxpUX"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:44:24.617Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
