TLS57: Christian Decker on Blockstream, Greenlight, Lightning Scalability, and More

Christian Decker is a researcher at Blockstream who has been involved in Bitcoin since 2009, and even did his Ph.D dissertation on Bitcoin.

In our talk, Christian and I spoke about Blockstream and their Lightning project called Greenlight, we discussed Lightning scalability, and we even got into things like channel factories, liquidity ads, peerswap, and more.
