Implementing it is the fun part! You might like going through the Raft lab in MIT's distributed systems course: https://pdos.csail.mit.edu/6.824/labs/lab-raft.html

Nice, I didn't know that course and I noticed that I can follow along the course, the classes are recorded. Do you think it's something worth investing to someone interested in distributed systems? The only downside is that I can't have my lab exercises validated.

Yeah, it's an excellent course. That is typically the unfortunate downside of self-studying courses, but AFAIK the tests aren't that sophisticated - you can mostly test it yourself just by running the test suite over and over again, making sure that it _really_ works 100% of the time and not just 98% of the time (given the nondeterministic nature of distributed systems failures). This is basically what students would do before submitting their labs, and most people got a full score if they ran it enough times :P

This is great, thank you!
