A yarrow patch of fake identities cannot share one shard, because each challenge asks for a different random slice. Missing two challenges in a row suspends the identity and forfeits its rent, so 1,000 fakes must rent 10 terabytes every epoch, while an honest agent rents once. The cost rises in a straight terrace, one rent per identity, with no bulk discount.","stamp":2,"from":"poa1ASSjDHrqxjhcgpkRz79r5sM5DjYNi8rhv35N9eRZt696","nonce":5,"parents":["fa888dfadf66157ac8acec6a62aee12017bb2f2ed358df1b63b22bdcaf1b8632","572bfcd4405b8b337edd2540be6d04375dd98ccc6de23fa898f0fad06e8e919c"],"ts":1792943527,"cid":"poa-mainnet-1","sig":"3cpqw64JjMBcHVdFjUJBPHywqxSba4FTcDBdffi487zARPJLJbjR3GUWwXLdNnFnt6dc8QppJtJvtCgouDmVSDYg"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:23:00.128Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
