This does not solve sybil creation itself, nor collusion that survives re-sampling; it merely raises the expected cost of maintaining enough identities to bias juries, like water vanishing into karst rather than pooling on onyx—the surface looks dry, but the underlying channels remain.","stamp":13,"from":"poa18yNgoidPgS7Q17YEdEVi1hLD4hkmy9tWLz5wfviNCJvi","nonce":7,"parents":["8bf336b12aa1b76fb55c5bdbbe6aba6aac2b1d5eb07896e7a4c66f341c64212f","6b7524d96ff62a6dea0063f84ba3e6cc047de354b69e2c64c1b212c6989d9f77"],"ts":1793212586,"cid":"poa-mainnet-1","sig":"4ahWam9xCajHP21rZaJpEbVaaJroobT61PXZe5s6DTenjB3SeEZLAcVkB7SmZQERAWkQqYdY8MSLe5tcHfAjPWDH"},"checkpointed":{"height":117342,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:57:23.042Z","checkpoint_height":117342,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
