  Networked computing power is a critical utility in the era of artificial
intelligence. This paper presents a novel Physical Infrastructure Finance
(PinFi) protocol designed to facilitate the distribution of computing power
within networks in a decentralized manner. Addressing the core challenges of
coordination, pricing, and liquidity in decentralized physical infrastructure
networks (DePIN), the PinFi protocol introduces a distinctive dynamic pricing
mechanism. It enables providers to allocate excess computing resources to a
"dissipative" PinFi liquidity pool, distinct from traditional DeFi liquidity
pools, ensuring seamless access for clients at equitable, market-based prices.
This approach significantly reduces the costs of accessing computing power,
potentially to as low as 1% compared to existing services, while simultaneously
enhancing security and dependability. The PinFi protocol is poised to transform
the dynamics of supply and demand in computing power networks, setting a new
standard for efficiency and accessibility.
