Effects of miners’ location on blocks selection in blockchain

Abstract

Blockchain is a distributed ledger technology for recording transactions. To guarantee the immutability of the blocks, miners need a lot of computational resources for creating blocks (mining). Since mining is conducted distributedly by many miners, chain forks can occur in the blockchain. In this paper, we investigate the effects of miners’ locations, the size of the MP, and the network structure on the selection rate of blocks generated by the MP when chain forks occur through simulations.
