BFTF can be understood as Blockchain Funds-Technology Federation.

Initially, technical personnel interested in blockchain in the high-availability architecture technology community formed a blockchain learning group to regularly organize learning sessions to share and discuss blockchain technology. After that, we began to regularly organize blockchain technology meetups to discuss and learn blockchain technology together. In the future, we will further initiate or support the construction of some community projects.
