Today on the podcast, Dr. Yonatan Sompolinsky and Brandon Zemp discuss DAGlabs. Yonatan is the founding scientist of DAGlabs. He received his PhD from the Hebrew University of Jerusalem. His research, which was mentioned in the Ethereum whitepaper, focused on the design and analysis of permissionless consensus protocols. He is the coauthor of GHOST (2015), SPECTRE (2016), and PHANTOM (2018) protocols. Yonatan is now a Computer Science postdoc at Harvard University, researching txn ordering incentives and dynamics (aka MEV). Yontan is a contributor to the Kaspa protocol, a new PoW base layer that implements his research work Listen to the full episode wherever you go on Anchor, Spotify, Apple, Google and more!

Dr. Yonatan Sompolinsky - Founding Scientist of DAGlabs

Aviv Zohar

Hebrew University academics Aviv Zohar and Yonatan Sompolinski joined us to discuss their research at the forefront of blockchain technology. We talked about their early proposals for scaling Bitcoin using the GHOST protocol, which later inspired Ethereum. And then we discussed SPECTRE and a new type of network based on directed acrylic graphs (DAG). DAGs abandon the blockchain data structure to allow constant generation of blocks that later get merged achieving block times of seconds and throughput many orders of magnitudes above current blockchain network. Topics covered in this episode:  How Aviv Zohar wrote one of the first academic papers on Bitcoin in 2011 The GHOST protocol and how it could allow much faster block times The difference between what Ethereum built and the GHOST protocol Why DAG (Directed Acrylic Graphs) have massive advantages over blockchains Towards massive on-chain scaling and speed with the SPECTRE Protocol Their view on existing DAG-based networks like IOTA and Byteball  Episode links:  SPECTRE Medium Post SPECTRE (full paper) Accelerating Bitcoin's Transactions Inclusive Blockchain Protocols On Bitcoin and Red Balloons Aviv's Website Yonatan's Website  This episode is hosted by Brian Fabian Crain and Meher Roy.
