Hashing It Out #6: Stuart Popejoy

ABOUT THIS EPISODE

This week's episode features Stuart Popejoy, founder of the Kadena, creator of the Pact smart contract language, and engineer/designer of the Chainweb blockchain protocol. We go in-depth on design decisions for Pact, how language simplicity impacts the security and adoption of second generation blockchains, how formal verification can be used to improve certainty in smart contracts, and the over-emphasis of Turing completeness for a very domain-specific language such as smart contracts. We go into the design behind Chainweb, an unboundedly scalable Proof of Work blockchain architecture, which expects to reach a whopping 10,000 tx/sec (864,000,000 tx/day) on its first year of release.

Hashing It Out #47 - MakerDAO pt. 1 - Nik Kunkel

MakerDAO has built a token that is reasonably stable with the USD. We have the great pleasure of interviewing Nik Kunkel, Head of Backend Services at Maker. In this Part 1 of 2 on Maker, we talk about the cryptoeconomics behind creating a stable token pegged to the USD. It's essential to understand this before getting into the technicals found in Part 2 of 2 (next episode, #48). This is compelling work, and truly amazing how well it's standing against the throes of the fluctuating markets.

Hashing It Out #46 - Ren - Loong Wang

We have CTO of Ren, Loong Wang, on to educate us on their token transfer protocol. Ren is building a system that allows a user to transfer a token from one change to another, without the drawbacks found in techniques like atomic swaps. They have a network of "dark nodes" which run on their virtual machine, RenVM, to computer across the transactions and share data over the network. Interesting technology with many use cases!

Hashing It Out #44 - Blockstream - Russell O'Connor

We bring you another brilliant mind on the show for this episode! Russell O'Connor, developer of Blockstream's Simplicity programming language for Bitcoin, dives deep into formal verification topics. We learn about the language design principles driving Simplicity, how formal verification plays an integral role in making the language suitable for securely automating Bitcoin transactions, and the challenges in creating a smart contract script for Bitcoin. We get a glimpse into the future of blockchain automation, and he elucidates what is being done right and what could be done better in blockchain platforms to place security first in smart contract design.
