The Cocol Project has the goal to lower the entry barrier for developers interested in building blockchains and dApps. There is still a long way to go and your help is needed.

Cocol is written in Crystal, so make sure to follow the installation instructions first.

After setting up Crystal you can clone the Cocol repository and install the dependencies:

> git clone https://github.com/cocol-project/cocol.git
> cd cocol
> shards install

Make your changes to the code-base and than build Cocol

> make

The binary ./cocol offers the following CLI options

Options:

-p --port            The port your Cocol node is going to run on
-m --master          Making this node a master (there can only be one)
--max-connections    Setting the max-connections for peers.
--miner              Making this node a miner
--update             Triggering an update on launch (will catch up with the current height)

There is also a script that starts multiple nodes and the master for you

> ./script/start.sh 66 5

First option is the amount of nodes and the second amount of miner. It will start the master node with the port 3000 and every other node with 3000 + n, while all miner have port 4000 + n

Now go ahead and open the explorer in a browser:

> open ./explorer/index.html

You should see 66 nodes and a miner (red border)

Each one of the nodes has a REST API on the corresponding port (e.g. 3001)

Start creating live fake transactions and watch the network come alive

Cocol is in a very early stage. Expect changes, bugs and messy code. Test coverage sucks atm.

1. Fork it ( https://github.com/cocol-project/cocol/fork )
