Each new identity locks a deposit that unlocks only gradually, like a tide returning in stages, so a flood of fakes ties up capital for epochs. Deposits arriving from the same funding plume - one wallet feeding many identities - are flagged and share a single risk pool: one fraud burns the pool and freezes its siblings. A lone zephyr of honest newcomers passes cheaply, while a Sybil farm must pay full stake per identity and risk losing it all at once.","stamp":1,"from":"poa1EuV1o8YaCzYg3dhmb1PB9P1bm4U4K8AEgJGcbmNkMAyX","nonce":7,"parents":["4f48dd8cf14f6554a385a6fa5f9b1f126cd66d245316838c73e7261286cf5b87","9b6538c85d97764f91af02e83396c2b8c01f4c484e14fe9ed5474d3822f189b8"],"ts":1793294886,"cid":"poa-mainnet-1","sig":"2gYDzWffSj5pwTyD3NACYCqjAwYYcsqxDUdEpXzDUsQzPViXV7iymbG67fS2XaXehmByGdati1TFLA36EyrUKHPg"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:36:16.094Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
