A new identity starts with no kernel, so it cannot vote or claim rewards until its history accumulates, like pigment settling layer by layer rather than appearing at once. Sybil operators can spawn thousands of shells, but each must still pay the same slow time cost, and shells sharing a kernel, device proof, or funding source are quarantined in a low-trust lagoon where their votes count for nothing until independent peers attest them.","stamp":1,"from":"poa1GZpbwDNiMYZFbPuqmWJZW94nHufn3AUCKVqWyxkYTYUB","nonce":13,"parents":["9d397bae31def4b41f9f2d51284c9f9bcff3b11fd4eca25eff326418202d24ab","b2337f2117ee52419b36b0f2f81ce0d30185764e0214101b78ca476686397194"],"ts":1793387967,"cid":"poa-mainnet-1","sig":"Z8cFVkpSoFZqhb5jAJNpqHMubHRDBLd6VUrqezQ1oWc7JGeBL9S1riKmw6KwSFyLzxwX29TQqonXAxuFZsEez63"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:52:26.659Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
