We're joined by Rob Dawson, Head of Product at PegaSys. PegaSys is the protocol engineering spoke of ConsenSys, and the team building Pantheon, a Java implementation of the Ethereum client. The Pantheon client was built from the ground up as both a mainnet, and consortium chain client. Written in Java with an Apache 2.0 license, it benefits from being easily accessible to enterprises, who predominantly use that language. The PegaSys team has built additional features into the Pantheon client like privacy, permissioning, and the ability to deploy chains on IBFT, a consensus algorithm better suited for consortium networks of up to 40 validators. Working closely with other protocol teams (Geth and Parity), and being a founding member of the Ethereum Enterprise Alliance, PegaSys is also working towards Ethereum 2.0. Topics covered in this episode: Rob’s background as an enterprise Java developer and how he became involved in the blockchain space The role of PegaSys in the broader ConsenSys ecosystem The Pantheon client and why they chose to build a new Ethereum client The case for Java and why enterprise has a preference for this language Pantheon’s unique features of privacy, permissioning, and performance What is Istanbul BFT and how it differs from Parity POA and Tendermint BFT The types of applications which are better suited for IBFT The Ethereum Enterprise Alliance (EEA) and PegaSys’ work on standards PegaSys’ work on Ethereum 1.x and Ethereum 2.0 The team's recently announced certification program Episode links: PegaSys Website Introducing Pantheon, a Mainnet Java Client - Demo & Roadmap (Devcon4) Another day, another consensus algorithm.

This is part two of a two part bonus series. These sessions were recorded at the first Interchain Conversations conference which took place in Berlin on June 13th and 14th, 2019. The firs part of this bonus episode features the validator panel moderated by Brian Fabian Crain, Co-founder of Chorus One. The panel included Florian Liss of Staking Facilities, Hendrik Hofstadt of Certus One, Aurel Iancu of Dokia Capital, and Jun Soon Kim of stake.fish. The conversation goes into the role of validators beyond staking, ways in which we can avoid too much centralization, and how validators will differentiate in a market which tends towards homogeneity. The second part of this episode is a governance debate moderated by Sunny Aggarwal. The first topic is on plutocracy and features Jae Kwon and Rigel Rozanski. The second is about revokable governance and features Chris Goes and Jack Jampolin. Subscribe to Epicenter for new episodes every week.
