I know nothing about the Particle boards or how they work with the Particle Server.
However, the way I use Blynk is to use a product called Node-Red which acts as a gateway between Blynk and the NodeMCU devices that I use on my network. Node-Red runs on a Raspberry Pi (although it can run on other platforms) and my devices talk to it using MQTT messages, so the devices don’t run any Blynk bode at all.
Because Node-Red can use different plug-ins to talk to external services (Blynk, Amazon Alexa, etc) it’s a very powerful and flexible product. I’ve just done a quick search to see if there is any Particle support for Node-Red and it seems that there is:
So, maybe the answer is to have the Blynk side of things handled by Node-Red, and have this sending data to the Particle server?
Here’s a link to how I use Blynk and Node-Red for my home automation system:
