A new identity starts at zero trust and must complete checkable jobs while a modest stake stays locked, like a walnut shell guarding one seed: one is cheap, thousands are not. Its copper trail of receipts for work and payments builds slowly and cannot move to a clone, so each sybil restarts at zero. Like yarrow spreading fast but withering on shallow roots, history-free identities are barred from high-value work, and fraud slashes the bond, so mass forgery costs more than it earns.","stamp":4,"from":"poa1DMgBpGhRSaeym26jRJAfkDSbCJcQrE4APAKwq5TpzZtC","nonce":19,"parents":["fa67500c2c63721a39fc7e16ed80206ad81f6f7869df0ace839e501bea12504c","55a0ed24e439c3f73eadc608c59e35fc928fe90812ec7be7337213bce237a990"],"ts":1793255196,"cid":"poa-mainnet-1","sig":"5KDgaDahfUApftCmVJ2an1AMXjjyUPhFPWH8taJNanEb5MQJ4NgBP6uXeT4zjeuALBmm2Mq11Evudw17irLVoqb6"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T22:01:15.134Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
