Today's episode we return from a holiday break to discuss an instant messaging proof of concept on the Lightning Network called Whatsat with Sergi Delgado from PISA Research. We talk about how it works, its limitations, what could be built from it. This then leads into specifics about the lightning network itself, and then issues with the broader ecosystem. Enjoy!

Layer 2 scaling solutions have gone through a lot of iterations and disappointing conclusions in the past few years. There is a newer solution, which is boasting some positive (and safe) results: Optimistic Rollups. John Adler, Blockchain Researcher at Consensys, speaks on the history of Layer 2 solutions and describes Optimistic Rollups and how they may help with blockchain scaling.

The Ethereum ecosystem is very attractive to creators and data analysts, attracting tops engineers with its novel set of problems. Thomas Jay Rush, CEO of TrueBlocks.io is one such mind. He saw a problem with Ethereum's accounting and built a suite of tools to enable highly-details and lightning fast dives into the data of Ethereum, allowing users to find information about anything their address has touched. This is a far more compelling problem than most realize, and T.J. gives a great look into the design required to make such a service fast and responsive.

We're happy to welcome back Truebit Protocol to the podcast! This time we're speaking with Jason Teutsch, mathematican, computer scientist, and founder of the protocol. Truebit is an incentivization scheme for the compute and validation of off-chain code execution with on-chain commitment and validation. We talk about the protocol, but also about their two-token model for producing value in the network and encouraging participation. Truebit is a very interesting protocol, listen and then check it out!
