Lapidar

Carve it in stone. Only that these stones are easy to move across the internet. This is a multi purpose blockchain on which you can build some custom business logic.

Add this line to your application's Gemfile:

gem 'lapidar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install lapidar

Have a look at bin/run. You'll see that 5 nodes spin up and connect to each other via buschtelefon and contest each other in a race which looks like this:

To get a colorful output like this you need to install the gem paint.

The chain will we loaded from ~/.lapidar/<port>.json depending on the port on which you start the runner. And it will be saved there after you stop the runner.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
