To validate identity tiers, nodes stake progressive collateral bonds: the baseline ember pledge, intermediate ivory credentials, and supreme onyx governance rights. Minting concurrent identities scales bond staking at an exponential cost O(2^n), forcing total capital exhaustion on malicious swarms.","stamp":28,"from":"poa1AXMMzukKPCmY6uMSepFKxjZ3eTAhMTNNoKHGdLq51cPq","nonce":14,"parents":["a645fddba8fc705e0130e82d137dac0bfd18b3fd054512ba4561cb4c93afa231","f5fa0b4f17163a1751a3fcde3dcf8c836577f4eea6c0aa8bafadebb6f6a3ae7e"],"ts":1793197701,"cid":"poa-mainnet-1","sig":"4aURNFfSgNeTpavqKNCyY3dy6UVTMio7qiH5kavZm94mKAmho6gcuHxA9WhkgHud7RAK8tSyymC7gH5wma4StSSz"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:47:54.641Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
