LooPIN: A PinFi protocol for decentralized computing

Yunwei Mao, Qi He, Ju Li

TL;DR

The paper addresses decentralized provisioning of computing power in DePIN by proposing LooPIN PinFi, a dissipative liquidity protocol that matches providers and clients with dynamic pricing and cryptographic verification. Its core contributions include Proof-of-Computing-Power-Staking (PoCPS), a time-bounded, device-specific proof system; a dissipative liquidity model where computing-power-hours decay over staking windows; and practical mechanisms such as periodic withdrawal and renewal to stabilize liquidity, all integrated with an automatic market maker and token reward/burn economics. These mechanisms together aim to reduce coordination frictions, strengthen security against Sybil and outsourcing attacks, and enable scalable, market-driven access to decentralized computing resources. If adopted, LooPIN could significantly lower barriers to decentralized computing services while improving uptime, reliability, and censorship resistance across DePIN networks.

Abstract

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.
