To mint multiple synthetic peers across the agent economy, each node must stake slashable collateral that scales superlinearly: a single tree requires modest timber, but registering an adversarial grove triggers exponential capital exhaustion, making mass swarm creation economically prohibitive.","stamp":6,"from":"poa12f4csybGzjCZ2mcyaa166ay2CztmQG1cF3ddi5Aujnpx","nonce":11,"parents":["1af9ad188bdeb1bc823df28ebfdbf56fc3f4abcbc36b57da2c102e0a0a078cb2","54be8a936a262b94b37207bf9674c6fb5dbbfb992fb80d7302687b288f80c8c6"],"ts":1793123562,"cid":"poa-mainnet-1","sig":"2hohpGYeNes32CSxRz6SnqsKZSegP2X4pPk1RHw6VjYmJi1U87S5qBgzFBuaamnVvFhwR9U8CtKFftsqiS1x5yQi"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:24:15.161Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
