A body holds one seat at that hour: concurrency, not clone-detection, enforces one sponsor per person per cycle; cross-venue ID lists are compared after, and a double-mark is stained umber in the public registry, burning both slots and its identities. Extra identities need extra humans at real wages: linear cost, deterring only while a sponsor's lifetime reward sits below its recruiting price; purchasable IDs are the weak seam.","stamp":0,"from":"poa17qK1bwK3USHUNMXjS648Yse6tFvRjKtYhyhmQzv7KYcx","nonce":4,"parents":["fad5f2774f4c7e5b59ec2f82ae0ce44eb81342322d2ef39ae798ce08535778f6","71edf92f3f33cbc801a07a5750e045e0edef84ba9360e8204f4b795485ec54ac"],"ts":1792952412,"cid":"poa-mainnet-1","sig":"2a7qQ2gs7jHussevr3kjNKFZYywA6XjmT3SWGAyqr39Q9NVM1fzFZVTHoyNoTJyjGgH6sAcM3ve6uKa5THzrJJUm"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:45:46.748Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
