On this episode, I speak to Zaki Manian from Tendermint. We get deep into the weeds of interoperability, his notions of interop between fast chains and fast and slow chains. We discuss the IBC protocol, which is a spec for adapters between different chains along with all the complexities when dealing with cross-chain communications. Moreover, we examine design and development principles when building product in this space, and the differences when building traditional software product. Zaki goes over some exciting projects that are building on Cosmos as well.

Topics:

• Who Zaki is
• Talking about interoperability
• Two classes of blockchains
• What is Cosmos trying to do
• Main issues when getting different chains to talk to one another

We then compare and contrast traditional and crypto derivatives markets. We also talk technical details of perpetual swaps and how they differ from other derivative products. Finally, we discuss the engineering underpinnings of the interdax platform and UX and UI considerations when building the product. We finish up discussing technologies Charles is excited about. Hope you enjoy this one.

Ben DiFrancesco, software consultant and founder of scopelift, joins us on this one. Two things we really respect about Ben are his ability to break down complex technical topics and also his ability to be honest about what crypto and blockchain offer us. He’s at heart, a technologist, and his passion for and dedication to crypto is palpable. This conversation contains a bit of philosophy around Bitcoin and Ethereum, particularly around how polarized the two spaces have become. We get into Bitcoin and Ethereum’s respective reasons for existing and how they can work together, how developers can use these new digital primitives to build applications, and business opportunities in the space. We also cover DeFi, and how smart contracts enable Maker and Dai.

Always enjoy talking to Ben, and I hope you enjoy this one.

Topics:

• Smart Contracts & use cases that excite him
  
• BTC + ETH working together
  
• DeFi movement
  
• Crypto Primitives
  
• Quality of Web Dev versus Crypto tooling
  
• ETH and “rich statefulness” and what that means
  
• Some techs outside of blockchain and crypto that he is excited about

Dr. Ed Felten is a professor of Computer Science at Princeton, he’s served as Chief Technologist at the FTC and Deputy CTO at the White House. He’s also the cofounder of Offchain Labs, a Princeton-based startup that’s focusing on 2nd layer smart contract solutions to improve scalability. This was one of our favorite conversations to date. We discuss smart contracts and their current problems. We discuss Arbitrum, Offchain Labs’ solution to the smart contract scaling problem which uses a system of validators to provide a guarantee to smart contract participants. Moreover, we discuss at length how their AnyTrust guarantee works, and why only a single validator is needed to maintain a working system. We also go through how an existing dApp can get ported over to Arbitrum. Finally, we talk high level tech themes: How technology and public policy are becoming more and more interconnected, how technology advising will become more and more important over time, and other technologies he’s really optimistic about. It’s a really packed episode. Enjoy.

Topics:

On the idea of "Bitcoin works in practice, but not in theory"
Smart contracts
Primary problems with smart contracts
Real world applications of smart contracts
What Offchain Labs is doing with smart contracts
Arbitrum & Validators
Porting Existing dApp to Arbitrum
Offchain business model

We have Rob Zuber, CTO from CircleCI on. A lot of the projects we work on implement CircleCI, so we were super excited to speak to Rob. We talk about his background and how he became part of CircleCI through an acquisition. We also get into one of his favorite topics: language. Particularly the words that are used in projects, and how important they are for workflow. We also discuss “Domain Driven Design,” or the idea that when creating a layer of functionality, to keep it bounded within its domain so other layers don’t creep into it. This was an engineering heavy episode that was a lot of fun. Hope you enjoy this one.

But before we get to the conversation, here’s a word from a sponsor, Blockchain Training Conference, that I’m really excited about. What if there was an educational industry conference, where all of the sessions were focused on teaching you something instead of selling you something? There is and it’s Blockchain Training Conference 2019. It’s going to be hosted August 28th to the 30th in Denver, Colorado. BTC2019 offers every attendee the chance to leave certified and confident in their understanding of blockchain technology. Move past the jargon to gain a robust understanding of blockchain and cryptocurrencies with master classes taught by industry luminaries like Andreas M. Antonopoulos, René Pickhardt, Jameson Lopp, Pamela Morgan, and many others. Register today and learn more at blockchaintraining.org.

We also have a coupon code for our listeners that you can use to get a 10% discount for the conference: quantlayer10

On this episode, we have Peter MacDonald and Joe Schnare from Wunderite, an insurance startup based in Boston. This was a really interesting conversation around how they are improving insurance workflows for agencies around the country through programmatic data aggregation. We talk about their backgrounds, get into the details of the black box industry known as insurance, and how they work with customers on product development. I learned a lot from this conversation. Enjoy.
