PHICOIN (PHI): The Proof of Work High-Performance Infrastructure

Guang Yang, Peter Trinh, Sannan Iqbal, Justin Zhang

TL;DR

PHICOIN proposes a high‑performance PoW cryptocurrency with Phihash, a GPU‑friendly algorithm that integrates Ethash caching, KawPow/ProgPow randomness, PCG32 randomness, and FP32 GPU optimization to resist ASIC/FPGA centralization. It advances a dynamic 25% per‑epoch DAG growth model and a 4 GB VRAM minimum to maintain broad participation, while driving fairness through memory‑based challenges and randomized access. The paper also details tokenomics with 95% miner distribution, a 5% mining fee funding infrastructure and developers, and a dual incentive system that combines PoW rewards with staking rewards to stabilize price and participation. A phased roadmap and empirical data from test mining and early deployment support PHI's potential to become foundational PoW infrastructure, enabling decentralized applications, cross‑chain interoperability, and future decentralized AI initiatives via the Phi Lab Foundation.

Abstract

PHICOIN (PHI) is a high-performance cryptocurrency based on the Proof-of-Work (PoW) mechanism. It aims to provide ordinary users with decentralized participation opportunities through an improved and innovative mining algorithm and fair design principles. PHI addresses the challenges of centralization in cryptocurrency mining by enhancing resistance to ASIC and FPGA devices and promoting fair participation. This paper outlines the technical specifications, mission, and roadmap for PHI, highlighting its potential to become a foundational infrastructure for PoW cryptocurrencies.
