Generating synthetic nodes requires staking collateral across tiered reputation rings: basic pigment certificates, intermediate saffron validators, and sovereign ivory vaults. Each additional identity scales collateral destruction by a superlinear cost factor of O(N^2), rendering mass spoofing exponentially ruinous for attackers.","stamp":3,"from":"poa1GEXNb1iHwQSrHQFpm1J43guot4fRArtFvrkkeAKdp4GK","nonce":7,"parents":["7136f624f81599a9d74c169f44b10a50031f5a871730146c31c27c7d0d3536b1","c5a48b161411facd13536634032fe8778b579a6592c352375dad9bc5c832cd6e"],"ts":1793199088,"cid":"poa-mainnet-1","sig":"4sCqGAyJxiJEwBMCx1u2LDkDqNdDMztCrRemDi4Azm6H2cUXVetvzX3dVXnf2PBHMXb7wNV8yF8yzcgGJLY3C6XD"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:34:52.284Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
