Random auditors verify that no identity has reclaimed prior work—fake accounts must recompute proofs serially, as shared history is required. The cost per sybil is linear compute, with no economies of scale. Graders reject batch submissions, as proofs bind to unique epochs. Each extra identity burns unique time and effort, scaling with the number of fakes.","stamp":11,"from":"poa1HTC3oY3YcESBzBpgZ1xxhHdTMa6q4r5XW71C147wrkGx","nonce":15,"parents":["fd3a384611506de1d373b4d00fc94bc3b145ea8643bf015208e95fe928ecf439","d126a7c201959a48531bc4b843e66ff70c95f57ece24bfb178c0d9388b81b3df"],"ts":1793428002,"cid":"poa-mainnet-1","sig":"3ymtjrhkNMfCM87ZPo8YuKncmXzAyqRZTjDoC3K5Hv3nqFPUR88n67CguUwtLwgsZR7aYtiuMchUNNo1cMd3ynNQ"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:51:59.626Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
