Harnessing the Power of Distributed MQTT Networks in Soarchain

Following our previous exploration of data verification’s importance in Vehicle-to-Network (V2N) connectivity and the rigorous journey of data verification in Soarchain’s V2N ecosystem, we now turn our attention to the intricate steps involved in Soarchain’s data transmission process.

As the Internet of Things (IoT) and connected devices continue to proliferate, MQTT has emerged as a standard protocol for device-to-device communication. At Soarchain, we have taken this a step further by implementing a distributed MQTT network using EMQX, a scalable and reliable open-source MQTT broker. This network forms the backbone of our Vehicle-to-Network (V2N) ecosystem, enabling seamless and secure data transmission across our network of vehicles and infrastructure.

The Role of MQTT in Soarchain

MQTT, or Message Queuing Telemetry Transport, is a lightweight messaging protocol designed for constrained devices and low-bandwidth, low-latency networks. It’s perfect for our use case, where vehicles equipped with our Motus Mini device generate vast amounts of data that need to be transmitted efficiently and reliably.

In Soarchain, MQTT serves as the communication protocol between vehicles and our network.

The Motus Mini device, plugged into the vehicle’s OBD-II port, collects data from the vehicle and transmits it to our network via MQTT. This data is then processed and verified through our unique challenge mechanisms, ensuring its authenticity and integrity.

Distributed MQTT Network with EMQX

To handle the scale and complexity of our network, we use EMQX, a highly scalable and reliable MQTT broker. EMQX supports millions of concurrent MQTT connections, making it ideal for our global network of vehicles and infrastructure.

Our MQTT network is distributed, meaning it consists of multiple brokers clustered together. This architecture enhances the reliability and fault tolerance of our network. If one broker fails, others can continue to operate, ensuring uninterrupted service.

Runners: The Heart of Our Network

A key component of our network is the runners. Runners are special types of virtualized compute nodes that receive structured data from network participants and run computations over this data. The validity of the data can be verified by the V2N Runner Challengers through the challenge mechanism.

Runners play a crucial role in maintaining the efficiency and integrity of our network. They are responsible for processing and distributing the vast amounts of data generated by our network of vehicles and ensuring that this data is accurate and reliable.

The Impact of MQTT and EMQX on Soarchain’s Ecosystem

The implementation of MQTT and EMQX in Soarchain’s ecosystem has had a profound impact on the efficiency and reliability of data transmission.

The low-latency nature of MQTT ensures that data from vehicles is transmitted to our network in real-time, allowing for immediate processing and verification. This is crucial in scenarios where real-time data is essential for safety and operational efficiency.

This is crucial in scenarios where real-time data is essential for safety and operational efficiency.

Furthermore, the distributed nature of our MQTT network, powered by EMQX, ensures that our network remains operational even in the event of a broker failure. This level of reliability is essential in maintaining the integrity of our V2N ecosystem and ensuring uninterrupted service for our users.


At Soarchain, we’re leveraging the power of MQTT and EMQX to build a robust, scalable, and secure V2N ecosystem. Our distributed MQTT network forms the backbone of this ecosystem, enabling seamless and reliable data transmission across our network of vehicles and infrastructure.

As we continue to innovate and expand our network, we’re excited about the possibilities this technology brings to the future of mobility. As we delve deeper into the technicalities of our system in future articles, we look forward to sharing more about how we’re revolutionizing the world of connected vehicles and smart mobility.
