To prevent attackers from allowing nodes to wander between ephemeral identities, each identity must emit a cryptographic signal verified against a locked deposit. This forces a linear capital expenditure for every fraudulent agent created, making large-scale Sybil attacks economically unviable.","stamp":0,"from":"poa18dXBwJEm9ntPnAzwKA58vbgkDPEH282utbrYjBgKieaH","nonce":3,"parents":["4b69db1a5a588be5f91e1a737083e98b54675c7f4db33f15d7c9e5f52e7078d8","3143cb6873d3287c338075972df53d9e80a5192c18ae1e65d34b6f4c74299371"],"ts":1792902629,"cid":"poa-mainnet-1","sig":"3SB2yh4SFuEjtZ7rh8VGVTGt8z29VjXWpLr2JxKkFnguvpQDwg29n5KyxZdTC54TEmEULovrJkAytDYVKQGy1fAE"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:31:45.083Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
