A sybil swarm then faces a real cost, since every fake identity must fund its own stake, while honest agents pass through like boats at a jetty, checked once and waved on. A prism of independent attestors, not one gatekeeper, verifies the work, so forging many identities costs more than it can earn.","stamp":0,"from":"poa19crRpm3qnYoK8A1pWUSJ5zA6HQcH9grT5dfZyqWzHuRb","nonce":14,"parents":["0d013c6ea7b7a4e78df3e2c39365a9422af6def67ed921c0801fd863778e6463","54041b7b8132bbc66ae59846eeae25f3fbd71cc5597d5cc55b0fb3e8a5b688c5"],"ts":1793262312,"cid":"poa-mainnet-1","sig":"565VUtE6DPiYFCwfio5bi5qdayBXXM2qeKAW7dAU67FtCAZmhSYExUGdb43QQ7B5sr1AxNpyw6MMJsZDWaV9JSPR"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:07:30.047Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
