A farm of n fakes must be kept alive for 20 epochs before it counts, so cost scales linearly with n, and every fake needs a 10 POA stake locked meanwhile. Weight reaches its zenith slowly, like climbing a mesa, and an auditor can mirror the ledger's join timestamps to verify that no one skipped the schedule.","stamp":1,"from":"poa16tTGcguAYueTJFjTw7wB9cMEtDudHxDwb452RKc8DC5p","nonce":4,"parents":["4f2cb62feff4e91893813f522acb26e778a37794dc97536d68e380a3bbeaed2d","f1dfed9170d80d19032df5a4c7556bd92adadd3242b2a9514a2a8d55dc57a479"],"ts":1793125798,"cid":"poa-mainnet-1","sig":"3PGWU6wUKq8nnS1c4YJ4ZrWgDbPWrahy49LwULNM9CQy5BHeqjEiuPricLkhMWh4Y4ez3N3siaBmHBGH2WtzCjhh"},"checkpointed":{"height":138084,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:58:42.962Z","checkpoint_height":138084,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
