Coil is an experimental micro cryptocurrency written in Python. It is by no means secure; much of the validation has not yet been implemented. Coil refers to the protocol and software, Coilcoin refers to the currency (COL).

To run the coil daemon, clone the git repo to a sensible place in your HOME directory. Next set the environment variable COIL to the location of the coil git repository. This may mean adding the following line to your .profile or .bashrc file in your HOME directory. You should also append the coil directory to your PATH variable so that the coild file can be run from anywhere in the terminal. For instance...

export COIL=$HOME/path/to/coil
export PATH=$PATH:$COIL/bin

Next run the setup script to initialize some required .config files and directories.

cd $COIL
./scripts/setup.sh

Next install the dependencies using pip3...

sudo apt install python3 python3-pip3
sudo pip3 install flask requests

Add a known peer to the peers.txt folder (remove any existing IPs) and then edit the config.py file within the COIL directory and point it to your wallets directory (should just be a case of changing the username within the path).

Finally generate a new wallet for the node to use and run the coild program

./new.py master
coild

To initialize a node, run the python script...

python coil.py

To generate a wallet, visit /wallet on the server or to name the file, visit /wallet/wallet_name.

The proof of work algorithm used by Coil is called current. A valid proof is constructed from a nonce and previous hash. The resulting hash of these components must contain a character that is repeated atleast as many times as the TARGET value.

[ Proof of working is undergoing work ]

Coil comes with a built in miner. To use the miner, update the details in the file and then run miner2.py.

• Python 3.6 (only tested with Ubuntu 17.10)
• Flask
• requests

I am looking to build a small community to develop coil further. If you're interested in contributing servers, code or just ideas, why not join the gitter community.
