The Lightning Network is an exciting ongoing development for the Bitcoin space. A promising protocol to improve the scalability and speed of Bitcoin, the LN will be presented in this talk by a developer familiar with the technology. The talk will briefly review the Bitcoin protocol and summarize the basic ideas behind the LN, followed by space for questions and a discussion.

Some questions that we'll attempt to answer:

• What is the Lightning Network?
• How does LN build on top of the Bitcoin protocol?
• Does LN help Bitcoin's scalability issues?
• Why pursue off-chain scaling?
• What does it mean to run a LN node?
• What is the current status of the LN?

The speaker is Henrik Jonsson, who is following the LN protocol and working on Bitcoin-related tech. Henrik has contributed to Bitcoin Core development, as well as earlier working for financial startups as well as for Google.
