Blockchain is a cutting-edge distributed technology that provides security, immutability, traceability and transparency of data. Normally, the use of this technology requires certain technical knowledge. Moreover, integrating this technology with other systems is an even more complex task. To deal with this challenge, in this demo we present Node4Chain, a novel extension of the Node-RED low-code tool that allows for defining graphical flows that specify data inputs, outputs and processing logic needed to monitor in real time blockchain networks such as Ethereum, Binance or Polygon, as well as integrating it with other systems and technologies. Thanks to the use of the low-code paradigm, performing this type of tasks is possible for people with less technical knowledge.
