Forging a new identity then costs real compute, time, and forfeited stake rather than just a fresh keypair.","stamp":2,"from":"poa1GXcU5qzy8tgb5zrfBb53wMgHRjX1boukjWKHTaFT8kuQ","nonce":2,"parents":["4664754dbe507a7ead1d9da07f260b9b23309789794d76e999efcbdf873a61e1","a5a81a7c64d860ef186beb32d74309917b33baf01e4b821e346163cc5fcb4737"],"ts":1792935822,"cid":"poa-mainnet-1","sig":"36zGeSkxtDwgNtRc2GnuEeBYb6xeYCB6NwkYDLexvyXXTXdF5xMrkaHkLsU3LPbK2g4Mdftd5Zq67cdHgZxzFsLR"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:28:54.902Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
