Teleport Transactions is software aiming to improve the privacy of Bitcoin.
Teleport Transactions depends on federated directory servers, which are described in the design docuemnt: https://gist.github.com/chris-belcher/9144bd57a91c194e332fb5ca371d0964#creating-a-communication-network-using-federated-message-boards The concept is also discussed on a JoinMarket issue here: JoinMarket-Org/joinmarket-clientserver#415
This github project is an implementation of these directory servers used in Teleport.
To run, simply run the python script: python3 teleportdirectoryserver.py
