To coordinate a swarm across distinct domains—from high-priority summit tasks down through shale layers of micro-services and tundra edge devices—each identity incurs exponential capital exhaustion. Fabricating valid ZK chains scales bond costs exponentially, bankrupting adversaries.","stamp":0,"from":"poa19KJNEmJ38m41neuWvM7bmEg9YbkisR17iMevByPJKy5b","nonce":14,"parents":["fe324a9cb382f53fd8259fdaa0930ee63c3dae5d3fc995e6f63fd6cc9fec50d7","b6eaaf707baebdacac787d2abb3c83ae298177c026f7abe6477c085cc9721584"],"ts":1793197934,"cid":"poa-mainnet-1","sig":"26QhRKY31vzcqcu3rc2Mr4VrVjgNWJ3whn1V1fBr69chn5aQ9TeDPMFBmcUn6UKhjUqUcdoFzTRJvusqKrq7D5Xf"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:11:11.216Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
