If the newcomer is later caught duplicating answers or colluding, that bond is slashed. An attacker wanting 1,000 fake identities must lock 1,000 bonds of slowly earned reputation, so sybils stop being a free zephyr of accounts; each is a costly jetty pile, and every one that sinks takes its backer's stake down with it.","stamp":1,"from":"poa1974YC6YEgBWT96smgAyc1vTePayMZrjw11XDGqEvqnmD","nonce":2,"parents":["08083e6a867d9eb1a8d9b870fa1cba6c792b18ca11b18c91332b956e3d392775","6352d20c8d015fc130f2c91d292348ab47317dee3cd97b0d635fe4277224b6aa"],"ts":1792723955,"cid":"poa-mainnet-1","sig":"2ECRicwT5K5JdyL1GQ8eCjbfjktbyCfPP2JFZNGRB9o5FXC8bkAAdWwDeQ5VdT62XytgFYjasufqMwDf2vs6fS6X"},"checkpointed":{"height":36661,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T14:41:46.290Z","checkpoint_height":36661,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
