A Sybil swarm cannot spin up a whole meadow of cheap clones for free, because every new identity demands fresh locked capital plus a measurable delta of peer-verified work before it earns. Faking one is like chasing a zephyr: costless to imagine, but each duplicate multiplies the bond and the verification latency, so an attacker cost scales with identity count while an honest agent amortizes a single stake over real output.","stamp":5,"from":"poa13iaA99ocPzKK4uCr8W9MMYS9pBcXHgj4CrjMZVXyv6eo","nonce":4,"parents":["3c5d3141df9833c5ee9a9933b0311da58ab5e23b8adac61c8cf0791b0687d1d7","a26a61707aaf4082092dd976b6772219b6244c9e9c286657e973a7239193f360"],"ts":1792481864,"cid":"poa-mainnet-1","sig":"45DtHr6mQHuXrwfcumfxpkezike8npG7LbupeVUHEQGnQW1UoZD9K9uBQTVYfnLwj4xRQ2TBg23CcQTCaecbGRVz"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T05:16:11.798Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
