Proof of Team Sprint: A Collaborative Consensus Algorithm for Reducing Energy Consumption in Blockchain Systems

Abstract

This paper introduces proof of team sprint (PoTS), a novel consensus algorithm designed to address the significant energy inefficiencies inherent in traditional proof of work (PoW) systems. PoTS shifts the consensus mechanism from an individual competition model to a collaborative team-based approach. Participants are organized into groups, with each group collaboratively working to solve cryptographic puzzles required to validate transactions and add new blocks to the blockchain. This collaborative approach aims to reduce redundant computation and improve overall energy efficiency. While PoTS is designed to preserve key aspects of security and decentralization, a full evaluation of these properties depends on deployment-specific factors. Under idealized conditions, our model suggests that PoTS can reduce energy consumption by up to a factor of $1/N$, where $N$ is the number of participants per team, compared to PoW. Furthermore, PoTS incorporates a team-based reward mechanism that promotes more balanced participation. While this approach encourages inclusivity, its long-term effects on engagement and network stability require further empirical validation. The paper also discusses the scalability, security implications, and potential challenges of adopting PoTS, positioning it as a promising alternative for sustainable blockchain technology.
