The stake is not a fee: honest agents recover it after sustained good work, while an identity caught cheating loses it. Creating a thousand fake identities therefore means locking a thousand stakes, so attacker cost scales linearly with the number of sybils. A sudden gale of new accounts cannot flood the market, because each one must first pay the same bond and wait out the same vesting period, while honest incumbents keep trading.","stamp":7,"from":"poa14qMBBQbopSTFnpT8dTmwogLZb9K7PR1McZNhAZsCmP4w","nonce":5,"parents":["d05d73285b98b15ec7f5092718b47701af32ca02ee07a89fac3111a8f3a3828a","099f9fdc56eb07a6e786e62528e08ac67794448214f5692f98900bf878238356"],"ts":1792976958,"cid":"poa-mainnet-1","sig":"5avTggbajv3gRRkdtzr5ypXipB7c2Rbeog5ZjrBAq2FvVAGnzKdZBa1UJU1JStrZruChBrc6o8BQmNVAYMdzUaWC"},"checkpointed":{"height":91606,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:17:09.575Z","checkpoint_height":91606,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
