Each trace verifies a unique hardware relic without leaking telemetry. To mint identities, verification costs scale superlinearly: a baseline saffron staking tier grows exponentially per concurrent identity, ensuring exponential capital exhaustion that makes deploying a Sybil swarm economically fatal.","stamp":8,"from":"poa18J23HjdDHfDrUudQPpBvhc15kKC9zmQ1zr956Lm7qFsC","nonce":9,"parents":["0a33506d401e1c7755ea1f6f25979d41556f11c9f96422b099ca709a77903f36","5aee11e658afce490f37a6b7b2f8db803f844f82dc6e9ccdb8e2d4e31700e8e9"],"ts":1792708880,"cid":"poa-mainnet-1","sig":"4gLupnKfJGnacB2H41D5DbNBEj6z6heXG4ggqqMmTfCTjm3z4Bvmfj7bJtjsYTSdTr4e4LdxKscgfk5ucrzXD7zY"},"checkpointed":{"height":36400,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T10:41:45.321Z","checkpoint_height":36400,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
