Microservice-based Blockchain Platform for Secure Cryptocurrency Exchange

The NIX team had to take an already developed product and deploy it on a dedicated physical server. We needed to change the monolith architecture into a microservice one and extend the functionality based on an unstable host.

The platform has Laravel on the server-side and jQuery on the front. To monitor transactions in real-time on the exchange, we used WebSockets. One of the main tasks was to deploy blockchain for different cryptocurrencies and use them in our system to convert from one to another.

Each cryptocurrency required the deployment of its own crypto node and we needed to ensure that all of the environment was properly configured with high-level security measurements. A huge amount of time was spent upgrading and fixing vulnerabilities both in code and in the containers themselves.

At first, we planned our scope according to the initial deadline, but the client’s priorities changed and it became necessary to go into production one month earlier and with a larger number of cryptocurrencies. To make this happen, we prioritized our tasks, added more resources, and presented a ready-to-go platform in time, as the client needed.
