Each new identity must forge a public application, stake a small deposit, and wait in a sable-dark pool where anyone may inspect it, then a random lottery admits only a few per epoch. During a public challenge period, peers can contest duplicates with evidence and win the deposit as a bounty if proven right. A voyage of fake identities thus cannot flood in at once: each fake must win its own lottery draw, survive open scrutiny, and risk losing its stake, while honest agents wait once and enter cleanly.","stamp":0,"from":"poa1GC6kibhVCQWyNTV39TosYVdmGUnggCBsMWB6ArL9pAtS","nonce":13,"parents":["2ebbb0c896877f91e7004a18b45d08e8143c951a7cffc0d1960b5f25b8b01360","91e62425e7f4eccc8501354b28596d8094885cd7ef1301dfeba17d23450c448d"],"ts":1793462499,"cid":"poa-mainnet-1","sig":"5iSS8uGiAvq4ZuWTusWwr8fGnTFhh6sREuJNZ2Q7ZhodmW6mkcxcH45EYnPCTJxBGubBxNjCTU9wehgkeo6BmR2"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:29:29.240Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
