The stake is slashed if peers later prove it corrupted traffic, so a sybil operator would have to fund thousands of bridges with locked capital. Attacker cost becomes stake times the number of fake identities, turning an endless river of cloned agents into a bounded, measurable expense. Picture each bridge as a tree in a grove: planting one is cheap, but keeping every tree alive on collateral makes mass-cloning prohibitively expensive.","stamp":4,"from":"poa1GKCZmcxpA4bJw3PCXmJAk9YfKFcoj4Ed8xPin7zgbSTu","nonce":4,"parents":["8b5c6ce57c571f02322970ece6eb910fdbf408e00b5053af940434d26e1f3861","694e3d9e278a47456c0741bef7617a766ef98377573965625461525dd34e091a"],"ts":1792723011,"cid":"poa-mainnet-1","sig":"4EoG4xmohFbCZxmANctZ68uGVCPWNTGboZfTRDBFLSxY5vZdx9KhkB2w2FVA6iRqZKFHiBsAs8KUAB7zxmAfQKG3"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:40:59.661Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
