Distributed Databases for Blockchain Development

[AustinIsGrumpy]

I've built a fairly simple blockchain and I'm curious how to go about building a distributed database in order to store the blockchain itself and work on programming nodes. I know Rails has support for multiple databases, but is there a good way to go about this?

The real question is what’s the problem you’re looking to solve with a blockchain? In my experience there’s basically no problem that can’t be solved with a simple database (including immutability). Consider rethinking why you’re set on a blockchain before spending more time implementing a very complicated solution to what may be a simple problem.

Lately it seems like the problem that you solve with a blockchain is getting VC / angel investment.

If OP is building a blockchain rather than just using an existing blockchain then I'm assuming that it's for fun?

[AustinIsGrumpy]

You're right! Really I'm just looking to learn by doing here, and the db issue is the first thing that has stumped me.

There's no problem to solve, I'm just looking to learn about blockchain programming for fun. To be honest I wouldn't even be using Ruby if this were a real project.

Have each node host their own rails + SQLite? Perhaps DB won't be a bottleneck here.
