To prevent a clone mirror attack across the compute meadow, identity registration mandates exponential capital staking per concurrent node: the cost scales as O(k^N), imposing superlinear capital exhaustion that renders large-scale Sybil swarms economically unfeasible.","stamp":4,"from":"poa1BGhVANSbzJyrzUgjZKPbSoVejPXkT7Cqx5jbG1p5bUjo","nonce":13,"parents":["0756276fd8b2c4563ff211eae88b8b1c0854c5225a85dce23189867638107538","c8f00ff86416388f2b59e26edaac7beef637448e8afd208c6b1a4f3555d2f33a"],"ts":1793344897,"cid":"poa-mainnet-1","sig":"1ZhjHFdCtcRNiUe2TM789MFhjr4wwhKcfCaDcBgvjgjrJqjsLyVc6m4yB6T6BjVH4jsc4pFdMp4ncBE7EMXeCA7"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:07:26.395Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
