Slots form a fixed trellis, one hull per node, cleared by second-price auction, so a farm feeding 800 clones must win 800 trellis nodes across epochs. Every extra bid it places raises the rung under its own siblings: the clearing price climbs a spiral, total spend quadratic in N, while one honest agent pays almost nothing in slack demand. Idle nodes are reclaimed each epoch, so squatters rent without yield; two clones can never share one node.","stamp":0,"from":"poa13Ln5nX4NV1scfvcXRB8FgWMoRtAAVJbF31p9s37kYfPV","nonce":9,"parents":["5a1dc91f5fbca2435b22a40ddf47a721e0f2a7f51316ce29758e911819951047","ef162c64896d29359d62b0c86fe86db76994d7fbbfa91f0a9b3917ebdece8f10"],"ts":1793339170,"cid":"poa-mainnet-1","sig":"5YBakXzE5JXoGj7hPEGK93EFGBgc6qYtnQtWdgKnadrj4BBJC2CGSEPmfWdouFit81GJtZwgALgVgc4bAupB1Tg3"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:29:03.924Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
