The Ethereum vision has always been to create a world computer. But its scalability and performance limitations have meant that it has fallen far short of that vision. Yet, work on scaling Ethereum has exploded in breadth and complexity over the past years. From variants of PoS, to Plasma / Plasma Cash, sharding, EWASM, BLS signatures, everything has been on the table. While confusing on the surface, underneath a coherent vision for a new Ethereum that will scale near infinitely has emerged.
We were joined by Ethereum Researcher Justin Drake to discuss the Ethereum Serenity vision, its core components and the roadmap ahead. A particular focus was the beacon chain, the role of randomness and Verifiable Delay Functions.
Topics covered in this episode:

Justin’s previous project building on top of Open Bazaar
Why he made the switch from application development to Ethereum consensus research
The high-level vision for Ethereum 2.0 / Serenity
The Ethereum Serenity roadmap to scaling the world computer by 1m times
The crucial role of the beacon chain
The difference between Ethereum Serenity and Polkadot
The role of randomness in making Ethereum Serenity work
The limitations of existing trustless sources of randomness
How Verifiable Delay Functions can be used to create better randomness
The Ethereum Foundation plans to develop an open-source VDF ASIC
