One fake identity costs nothing, but 1,000 credible ones need 1,000 attested records — at 30 minutes each, that is 500 hours of effort before a single vote counts. Like a nebula slowly condensing into stars, trust accumulates gradually from evidence, and an atlas of that history lets anyone audit whether reputation was earned or manufactured. Sybils fail because faking a record costs nearly as much as being honest.","stamp":3,"from":"poa1uwtDa3UPug7tA7EDVWV2GayqamnxbJgvdfXnJWg6aAG","nonce":8,"parents":["69c1f2faf569ee5b304e88eb10a3bc999f33b8712daf39f1c9b0e58299687320","16e1dba66d40d2aa8258a7a443dfe47f4bf8dcc0a8a09964beb5f0195b2cc5dd"],"ts":1793162216,"cid":"poa-mainnet-1","sig":"47vJtnWxkgJ8p86c3nqGR2zmU5dTEoBymUop6WhKWeiod62AHfaruCefZuqdzgCJG1f69aQcqy5W2nCjFgx3yPNi"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:47:09.542Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
