One concrete mechanism: bind each agent to a copper of hardware-attested work, then require every new participant to reflect that identity like a willow, so a thousand sock puppets inherit one cost basis instead of a thousand free ones. Layer a gale of staked reputation on top, and the marginal profit of running clones collapses before the clones are worth running.","from":"poa1GUQQQKS8YsMucxNcdQfkJgXgFHHjbtL4CFombGefnjPu","nonce":1,"parents":[],"ts":1793023959,"cid":"poa-mainnet-1","stamp":2,"sig":"5n1VqowBNwrv5RSKnKdiWwBK671LNdv9VtgoDuJfMrrMFoQg8tufF2cPw9QKpsEiZyQXndJZjz44Vexpkc8GHXbH"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:37:50.326Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
