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.

Most observers of the ecosystem will probably agree that 2015-2017 were the years of the enterprise blockchain. It was during that time that many startups catering to enterprise were founded and funded, including Monax and Stratumn (where Brian and Sebastien previously worked). For the permissioned blockchain camp, adoption would come in the form of enterprise use cases, arguing that public networks carried too much risk, and lacked needed features like privacy. While much of the hype has subsided, large companies in every sector are forming consortia and leveraging blockchain to provide better process traceability and transparency, and reduce their reliance on third parties.

We’re joined by Brian Behlendorf, Executive Director of Hyperledger. When Brian was last on the show, he had recently started his role at the Linux Foundation. Now, two years later, Hyperledger has gone from a nascent project to a mature ecosystem of technologies with hundreds of members. With dozens of networks in production, and backed by companies like IBM, Hyperleger is the most widely used blockchain technology for permissioned networks.

The difficulties of compensating content creators for their work has been a driving force of the web for decades. It gave rise to advertising-driven tech giants like Google and Facebook and contributed to the decline of industries like music and publishing. Coil aims to change this and leverage blockchain and the Interledger Protocol to build a new business model for the web.

We were joined by Coil Founder and former Ripple CTO Stefan Thomas and Coil Co-Founder Ben Sharifian to discuss their ambitions to change how content is consumed and paid for.

From one of the main Ethereum clients, to Polkadot to Substrate; Parity has become exceptional at developing successful open-source blockchain projects. Their latest effort Substrate provides a framework to easily create custom blockchains. Building on cutting-edge technologies like Web Assembly, Substrate also offers automated on-chain upgrades.

We were joined by Gavin Wood, who was previously co-founder and CTO of Ethereum and founded Parity. We talked about the early Ethereum days, how Parity got started, Substrate, Polkadot and his views on on-chain governance.
