Tau

Encrypted tasks management app using peer-to-peer network and raft consensus.
multiple users can collaborate by working on the same tasks, and all users will have synced task list.

Install

% git clone https://github.com/darkrenaissance/darkfi 
% cd darkfi
% make BINS="taud tau"
% sudo make install "BINS=taud tau"

Usage (Local Deployment)

Seed Node

First you must run a seed node. The seed node is a static host which nodes can connect to when they first connect to the network. The seed_session simply connects to a seed node and runs protocol_seed, which requests a list of addresses from the seed node and disconnects straight after receiving them.

in config file:

	## P2P accept address
	inbound="127.0.0.1:11001" 

Note that the above config doesn't specify an external address since the seed node shouldn't be advertised in the list of connectable nodes. The seed node does not participate as a normal node in the p2p network. It simply allows new nodes to discover other nodes in the network during the bootstrapping phase.

Inbound Node

This is a node accepting inbound connections on the network but which is not making any outbound connections.

The external address is important and must be correct.

in config file:
	
	## P2P accept address
	inbound="127.0.0.1:11002" 
	
	## P2P external address
	external_addr="127.0.0.1:11002"

	## Seed nodes to connect to 
	seeds=["127.0.0.1:11001"]

Outbound Node

This is a node which has 8 outbound connection slots and no inbound connections. This means the node has 8 slots which will actively search for unique nodes to connect to in the p2p network.

in config file:

	## Connection slots
	outbound_connections=8

	## Seed nodes to connect to 
	seeds=["127.0.0.1:11001"]

Also note that for the first time ever running seed node you must run it with --key-gen:

% taud --key-gen

This will generate a new secret key in /home/${USER}/.config/tau/secret_key that you can share with nodes you want them to get and decrypt your tasks, otherwise if you have already generated or got a copy from a peer place it in the same directory /home/${USER}/.config/tau/secret_key.
