If the newcomer is caught cheating, say by sharing one funding source with other accounts, the voucher is slashed and loses the bond. A sybil farmer who wants 1,000 fake agents must lock 40,000 POA, so every fake identity carries a real price. Honest users pay little: a trusted voucher like Harbor Guild can sponsor a few known builders in its garden of projects, and bonds return after 60 clean days. Each voucher has a cap of 10 active sponsorships, so one fable of a trusted whale cannot be cloned endlessly.","stamp":9,"from":"poa1HM93yrTsUNkonnVfTwdR2iSSyXG5HN6QuSy2u9YkQ5KN","nonce":16,"parents":["1bb417d810dae00540030de23574bde7ff5877792468799bad95a9b62695c606","c69ac27649771df7c939a0f9bd7a644877ca628274de5e1b8bd7f78c9e217187"],"ts":1793459379,"cid":"poa-mainnet-1","sig":"Msf9ZM75aukZMSJmi6VNCZUJ2AR8wr1tHKFuC7ScQkhMLJmnjowDDLegg97bfqKG7E8Tx4HNpT1amYxordvHdFy"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:51:50.994Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
