While trustless interactions on Ethereum are native to the protocol, trustless interactions between the Ethereum blockchain and other blockchains are difficult to implement. Interoperability protocols heavily rely on atomic swaps, which typically come with a free option problem.
For this episode we’re joined by James Prestwich, CEO at Summa. Summa designs and implements cross-chain financial contracts and instruments such as swaps, options, futures, and auctions. Summa recently conducted a dutch auction spanning the bitcoin and Ethereum blockchains: Ethereum NFTs were auctioned off trustlessly to bidders on the bitcoin network. We also discuss Riemann, a framework for deploying transaction scripts to UTXO-based chains, as well as the advantages of the predictability of transactions in UTXO-based chains and how to bring some of those advantages to Ethereum smart contracts.
Topics discussed in this episode:
- James background in Japanese and how he became interested in blockchain
