Collaborative Proof-of-Work: A Secure Dynamic Approach to Fair and Efficient Blockchain Mining

Rizwanul Haque, SM Tareq Aziz, Tahrim Hossain, Faisal Haque Bappy, Muhammad Nur Yanhaona, Tariqul Islam

TL;DR

The paper tackles high energy consumption and centralization in Proof-of-Work by introducing Collaborative Proof-of-Work (CPoW), a dynamic, decentralized mining framework. It anchors the approach in a formal foundation and a decentralized workflow that uses dynamic group formation, a private CVRM blockchain, distributed key generation, and threshold cryptography to ensure fair reward distribution and secure withdrawals. Key contributions include dynamic mining pools, a decentralized reward management mechanism, and an empirical evaluation showing improved fairness for weak miners and rebalanced efficiency across participants. The work has practical implications for reducing energy waste and promoting decentralization in Ethereum-style PoW networks through collaborative, verifiable mining.

Abstract

Proof-of-Work (PoW) systems face critical challenges, including excessive energy consumption and the centralization of mining power among entities with expensive hardware. Static mining pools exacerbate these issues by reducing competition and undermining the decentralized nature of blockchain networks, leading to economic inequality and inefficiencies in resource allocation. Their reliance on centralized pool managers further introduces vulnerabilities by creating a system that fails to ensure secure and fair reward distribution. This paper introduces a novel Collaborative Proof-of-Work (CPoW) mining approach designed to enhance efficiency and fairness in the Ethereum network. We propose a dynamic mining pool formation protocol that enables miners to collaborate based on their computational capabilities, ensuring fair and secure reward distribution by incorporating mechanisms to accurately verify and allocate rewards. By addressing the centralization and energy inefficiencies of traditional mining, this research contributes to a more sustainable blockchain ecosystem.
