About 🌐

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.

Installation 🏹

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

Usage βš”

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

Development πŸ‘©β€πŸ’»πŸ‘¨β€πŸ’»

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