Towards Real-Time Monitoring of Blockchain Networks Through a Low-Code Tool

Abstract

Blockchain is a secure and distributed technology which is growing in popularity since it enables the traceability, immutability and transparency of data. However, monitoring blockchain networks requires experts who have vast experience in this technology. To address this challenge, in this paper we present a low-code tool, which allows inexperienced blockchain developers to define graphical flows that specify inputs, outputs and the logic necessary to monitor in real time the elements of a blockchain network. This tool has been successfully applied to a vaccine delivery scenario, facilitating the monitoring of a smart contract that stores temperature measurements of a certain vaccine. As a result, when a new transaction is mined in the blockchain network, it will be promptly notified and sent to the different data sinks specified in the flow modeled by a non-expert in blockchain.
