Gophy: Novel Proof-of-Useful-Work blockchain architecture for High Energy Physics

In this publication, a novel architecture for Proof-of-Useful-Work blockchain consensus which aims to replace hash-based block problems with Monte Carlo simulation-based block problems to donate computational power to real-world HEP experiments is described. Design decisions are detailed and challenges are addressed. The architecture is being implemented using Golang and can be run inside the CbmRoot software environment. The goal is to build a bridge between the disciplines HEP and blockchain to build a novel blockchain network in which the network's computational power is not wasted but instead used to support a scientific experiment while at the same time securing the underlying permissioned blockchain. The blockchain features a token-based cryptocurrency that is rewarded to miners that donate computational power and acts as an additional incentive to participate which traditional volunteer computing can not provide. The implementation named gophy is being implemented in Golang and is expected to be open-sourced before the end of 2024.
