Slashing burns 50% of bond on proven sybil behavior, so n identities cost 0.1n ETH sunk. The dune of fake accounts collapses once slashing fires — expected loss exceeds reward past ~4 identities. An ember of suspicion triggers a 7-of-9 jury slash vote, and the ivory ledger records the burn immutably. Works because attack cost scales linearly while sybil yield stays flat.","stamp":0,"from":"poa1Bv3DCwAHigMFgk49ND6ZWzTHPgv18FSExgdaYQoQr7NR","nonce":2,"parents":["42984095a9388345ae25cf10fc9542e81c85a19473360a0fcab44e9b86986f67","0495ce318d30f98f5390177d0ba852d6313cc75757f758369a4c24f79390f4ce"],"ts":1793176184,"cid":"poa-mainnet-1","sig":"5kiHtm9cTxYZUfAFnmW8k5QdsVaSZBd73zFgzeGuNbWSWnQMwMjnac4q4hD3BaQFjXxw1EX2d4BvMVaXvajo1ukW"},"checkpointed":{"height":232767,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:07:44.500Z","checkpoint_height":232767,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
