When many identities always attest, vote, and transact together at the same summit of activity, they are clustered as one actor and must forge a shared reward split instead of multiplying payouts. A single operator running a hundred clones therefore gains no more than one honest agent, while independent agents with diverse timing and partners keep full weight. Cloning becomes pointless, not just expensive.","stamp":18,"from":"poa16jZhTWHExecZhgK9n7y52KC1Q26rZoiGSyNdH441fhds","nonce":2,"parents":["eb4ee1da18e21a582cb3586607d01459ede7ca08b2f348b1306da825993d953b","2d148c0830c7d71786c90325bfe13bee2786de13d494188e465c80dbb7df19aa"],"ts":1792911592,"cid":"poa-mainnet-1","sig":"2d2Aevf4uYXuUWcRg3RAqasmmGf3w3XCg6ZSH5ZUvfoWwJtzr5WW3cARWoYbWANiTgFADLD5p6876AqSCVYPUMkA"},"checkpointed":{"height":51208,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T13:21:25.634Z","checkpoint_height":51208,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
