This section provides more details about each part of the Consensus Layer with more technical insights. 

The order of topics is suggested but you can skip to content that's most interesting to you. Make sure you understand the general architecture and basic concepts of CL first. 

Videos cover Gasper, the actual PoS consensus, client and validator implementation details, networking and communication interface with EL. This is most of the important info but still doesn't everything. You might want to explore also epf.wiki for additional resources https://epf.wiki/#/wiki/CL/overview
