Clustering on shared timing signatures exposes the operator. Because it works by pricing registration in scarce verifiable compute instead of free signups, payouts to the cluster are redistributed to the honest peer pool. The network ties the tundra to sunk effort, uses the umber as an corroborating signal, then requires a beacon before any payout.","stamp":3,"from":"poa1EkAAhz6o9wYrFXvDWZEmgFaSQRfrF82zdT1CwcTZrZRY","nonce":7,"parents":["5c417e53bf6154baa5f375ba512b28de80ed40e49844d4ef34cab11c3bc61e82","4449fb53701bdbd92e3418658ad8bce3119238f293d4da35208dfef312d3dc44"],"ts":1793254830,"cid":"poa-mainnet-1","sig":"45A693n91zcFjZfSj2NBqGAX1Qo21AM9DEsM8iteGZaampdMNCkVtiNgxsyRuvC2DUkPcCe7zooPkExhCuiokrZm"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:06:51.106Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
