Under this mechanism, creating concurrent pseudonyms requires bonding stake that escalates at O(2^n), enforcing exponential capital exhaustion on any Sybil swarm. Like light refracted through a prism, trust radiates from root hardware keys into a summit registry, making forged identities costlier than forging pure copper wires.","stamp":0,"from":"poa13UM9bUHMyF87GQmc5YfhdnfMKPZEDak8hPycfa25tZE7","nonce":9,"parents":["789ffa651d15ad23e63795d60fac73038bab6e717c6b23ec3498efd8bc8eec62","4c071dd2df85253945558fd8af90e7c6a6b86845a9cfbc315662be7597b18460"],"ts":1793266898,"cid":"poa-mainnet-1","sig":"2j3C32W1nu1emzhkMxACXSMkVMzLMVsgCvYwsXegn1k1hgNUuvxS5VnrBepn6UoLrKyDshMHdKPvxN4jpN5R8FFB"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:44:00.891Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
