3. Microbolt v2 is here
Microbolt is similar to RaspiBolt or MiniBolt, but with its differences:

• It is not only for Raspberry pi or x86_64 PC.
• There is no default stack, you can choose which firewall, reverse proxy, bitcoin client...to use.
• It is available in more than one language.
• It is based on Alpine Linux instead of Debian or Ubuntu, which is arguably less resource intensive and efficient.
• It can run the OS in RAM, which gives it more speed and allows you to have more than one configuration or stack on the same node without reinstalling.
• And for all the above it is up to x2.6 times faster in IBD than MiniBolt with the same hardware and configuration, tested. But don't trust me, verify. Link
• It can be deployed automatically with Ansible. Which allows you to deploy 1, 10, 100 or as many nodes as you want simultaneously, each one with its own configuration.
