Abstract

Mining is one of the foundations of cryptocurrency. The proper functioning of this system depends on the participation of miners. In a decentralized environment, honest behavior is encouraged by protocols, assuming that compliance maximizes profits. A deviation from this behavior, called Selfish Mining, can increase the profits of the miners who practice it and compromise the security of the cryptocurrency. Currently, identifying this type of behavior is complex and performed using statistical tools that assume that miners have stable computing power during the analyzed period. In this work, we investigate whether miners actually have stable computing power and assess the consequences of variations in this power under current methods.
