Since Gavin Andresen’s proposal to increase the Bitcoin block size, how Bitcoin can scale to accommodate higher transaction volumes has been heatedly debated among developers. One of the most promising long-term options to allow near infinite scalability is the Lightning Network. Joseph Poon and , the co-authors of the whitepaper, joined us for a discussion of scalability and how the lightning network could allow massive numbers of off-chain transaction in a trustless way.

Topics covered in this episode:

Why Bitcoin has a scalability problem
How payment channels work and the architecture of the Lightning Network
Why the Lightning Network would still require a block size increase
How transaction fees would work in the Lightning Network
How the Bitcoin blockchain would take on a court-like function to ensure honest off-chain behavior
The risks and downsides to the Lightning Network
