The topic this month: Lightning Network.
https://lightning.network/

Lightning Network is fast becoming a reality with successful tests having taken place and a new ecosystem preparing to come to life. We're lucky to have an early adopter and programmer in our community who works with the technology regularly. Daniel Babbev, a Bulgarian student in Shenzhen, is working on new products for the Lightning Network and he will give an overview along with a demo of the technology, then answer questions. If you haven't been to our meetup before, make sure to come early and grab a beer or drink. The venue is very small and set up for a cozy chat more than a big presentation. We don't have any formal presentations. It's usually just small groups chatting about different interests and topics. FYI, Bionic Brew accepts payment in Bitcoin so bring your BTC to pay for those pints!

Also, please buy a beverage from the host venue, Bionic Brew, and support those that support the crypto community.
