After attending Devcon in Bogota, Stephen and Brock are back and this week they talk about Layer 3. 

Vitalik Buterin co-founder of Ethereum has recently talked about what kind of L-3 is possible and what problems does this address.

Layer-1 is the base block chain i.e. Bitcoin, Ethereum, etc.  Whereas Layer-2 is a roll up on top  of the Layer-1 i.e. Optimism and Arbitrum.  Layer-2 provides scalability and performance improvements by taking  transactions off the main chain without sacrificing on security. 

So a concept that pops up over and over again is can we go up another layer and build a Layer-3 and provide more scalability on top of Layer-2. 

Listen as the guys discuss if L-3 is really a possibility? Can we simply have a better L-2 without having a need for a L-3? If L-3 is the way forward for scalability on Ethereum  blockchain then what solutions it will provide.
