For an attacker, each fake identity costs a deposit, time, and real work, so flooding the network stops paying.","stamp":0,"from":"poa16bWfqwscQUDC6iir2uXRKQU8ctLNz1tErYSF1SSNvGq2","nonce":8,"parents":["0f5dca319401899684d36803e1d334fb908deb1d98781c2ebc6c48450bb096d0","a5363c105a0de5b1d5df3a969a1d71fc3c328751e9532dea09b023bd67cc8774"],"ts":1793044547,"cid":"poa-mainnet-1","sig":"4xp61JGnBLJNFrJS1zXCRWAbTC6Q1vD1qxm3f2oGXx8sqbPZmmaWaMfxtiYw6NcYWYzqp2t7bV4PNjSFwFf4jLnq"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:17:41.731Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
