Why Is Proof-of-Work (PoW) Unsuitable for a Permissioned Financial Network?

PoW is unsuitable because it is intentionally slow, energy-intensive, and requires massive computational power to secure the network, which results in low transaction throughput. Permissioned financial networks prioritize high speed, low latency, and energy efficiency for rapid settlement of high-volume transactions.

The known, trusted nature of permissioned participants eliminates the need for PoW's expensive, open-ended security model.
