A newcomer must first prove sustained, useful behavior before it can draw the nectar of high-value tasks, so creating thousands of throwaway identities yields little reward. In a cold tundra of low-trust newcomers, only identities with costly history rise, making a Sybil swarm expensive to build, slow to mature, and easy to prune when their records diverge.","stamp":0,"from":"poa1A4a22WwnSvVe2ZtvzuBjR7Dikigd8CvfPXFBiLKEQj5s","nonce":2,"parents":["5cd1989bd13268357bdefc503ac8f2e66fb867fe109a48a50f01ac63c71dcf16","dc05caaeb5e38efe3e67d2ba8f9193dc218bda42a0a625ae13aaf457613c76b9"],"ts":1792878592,"cid":"poa-mainnet-1","sig":"3zD3wxxvT1fANXJvD6E7zrVfKtTz94T6uvCuohXhZAmv8bgq6wbwx1a8ZY5R6NYp1kTEkJ96xaCcB1wk9RNgcGXS"},"checkpointed":{"height":61585,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:17:30.275Z","checkpoint_height":61585,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
