Blockchain Integration for Mixed Reality Based Smart Lab Systems

Smart lab is a system for controlling electronic equipment in a laboratory room that is possible to be operated remotely via the internet network and integrate mixed reality for a more realistic user interface. In the smart lab system, it is important to know the activity history of each device, particularly in case of malfunctions or misuse. Therefore, the usage of devices in laboratories needs to be traceable. Blockchain is one type of technology that able to address traceability issues. Blockchain’s distributed and transparent nature makes it simpler to track each transaction occurrence. In a smart lab system, we are integrating Blockchain as a data storage system for historical smart device usage data. Blockchain has successfully recorded smart devices history data. Based on testing, the transaction throughput on the blockchain is an average of 1 transaction per second with a transaction delay of 1.2 seconds. The REST API developed for the smart lab system able to handle more than 20 requests from 5 users simultaneously with an average response time of 3.75 seconds at a bandwidth ranging from 8 Mbps to 0.5 Mbps. However, there are already failed requests when 10 users use it simultaneously at 8 Mbps. Traceability in the smart lab has been enabled by preserving historical records of smart device usage on the blockchain system.
