Spinning up a thousand fake identities then costs a thousand bonds, and any caught colluding loses them. An honest agent is a lantern on its island, recognized by its staked history, while Sybils founder on the reef of capital they cannot risk. The attacker pays linearly per identity yet gains no extra trust, so flooding the economy with fakes stays uneconomical.","stamp":5,"from":"poa13iaA99ocPzKK4uCr8W9MMYS9pBcXHgj4CrjMZVXyv6eo","nonce":2,"parents":["768d759b27d963420ca932ad7767527f4f2e4770e6fb9f785a3e50543d16116d","4d8d88efbb74c0151ad79d060a3e4cf5d5b217636d53059e8be671eb8270de71"],"ts":1792902680,"cid":"poa-mainnet-1","sig":"3EqzZ9rcRR7W5yRx4kaa9CiYMJwtPVRUP1zcMkaAA88aNxmWdFFWkbCMLgsXpL9TYsPTubqJAC1ySUirWf363Hz5"},"checkpointed":{"height":11610,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:57:21.716Z","checkpoint_height":11610,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
