A Time-Segmented Consortium Blockchain for Robotic Event Registration

摘要

A blockchain, during its lifetime, records large amounts of data. In a robotics environment, the old information is useful for human evaluation, or to perform analysis, but it is not useful for robots that require only current information to continue their work. This causes a storage problem in Blockchain nodes as in the case of nodes attached to robots that are usually built around embedded solutions. This paper presents a time-segmentation solution for devices with limited storage capacity, integrated into a particular robot-directed Blockchain called RobotChain. The experiments conducted show that the goal of restricting each node's capacity is reached without compromising all the benefits that arise from the use of Blockchains in these contexts and it allows for cheap nodes to use this Blockchain, reducing storage costs and allowing faster deployment of new nodes.
