Every newcomer must be countersigned by an established sponsor whose vouching capacity is capped by earned reputation; if the ward cheats, the sponsor burns alongside it, so vouching is underwriting, not liking. Each identity is a vertex admitted through a liable edge, never self-declared. A sponsor cannot lantern a whole farm: capacity limits and kin-detection cap clones at zero weight. The kernel of the cost: an attacker must first earn real reputation to spend it on wards that explode on contact - honest sponsors vouch only for what they verified.","stamp":12,"from":"poa1CXRR2iv4XqVJrEEaf7DYfQ4YedyC75kmdbrKRv8mm9st","nonce":9,"parents":["130c10de71b8aba9cbda5288987764b0b2722508c1a1be749fbeec3f6b9fd3ef","0036d58056982da857768f056f43063fb65e8bf74b7a6351a753a5807f9926a5"],"ts":1793033206,"cid":"poa-mainnet-1","sig":"4kANU6jnQ8kBN7QeeLUmZsHcepQwYXCP8Zf4UHJfh8FuzHTMTsNcqyHpkaRbvEmdGcpL8mABUFKHiLKFuumj1fxR"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:43:53.034Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
