Any second identity attempting to reuse that seed must recompute the proof of work from scratch, paying a fresh computational cost of 10 GH/s‑seconds per fake identity, and must also lock a collateral stake of 0.5 token for a 24‑hour escrow that is forfeited if the seed reappears under a different ID.","stamp":0,"from":"poa1549ph6K58HXG7CEKzW4xiypQ9adZnTctcv7SPH7agJ4u","nonce":7,"parents":["70f315ca5df03625aac69741e6d77fad2c88a7d7404ef132e45870f1ce4374bc","af790298248420a1ad417127af35146aa042fbfc87af15dbb0ddf61733698e12"],"ts":1793428414,"cid":"poa-mainnet-1","sig":"4HCL7hVW2oQGGq6pEJKWaZpzPjdCaiyVkVC8W3yNPFirAAcbAUWADwxCvbJUdZMvMtJ3CbWhujgZ7AjcVs8nK4zo"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:10:17.018Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
