Codex32, Simplicity, and Drivechains with Andrew Poelstra - Blockstream Talk #29

Welcome back to Blockstream Talk, today's focus is Andrew Poelstra the Director of Blockstream Research. Over the last 6 years Andrew has steered various projects that might have flown under the radar yet these initiatives, cultivated by Andrew and his team have been crucial to Bitcoin’s development and infrastructure.
Andrew shows off Blockstream Research’s awesome new book Codex32 which teaches users how to build paper computers, known as volvelles, for use in learning and executing Shamir’s Secret Sharing schemes.
We also delved into topics like Miniscript and its potential integration on the Blockstream Jade hardware wallet, along with a review of Simplicity. For those intrigued by Simplicity, don't forget to revisit Blockstream Talk #26 - Simplicity, Bitcoin’s Last Soft Fork?
This episode was huge including dialogue on Drivechains, Bulletproofs ++, CTV and APO analysis, Frost & MuSig2 updates, Zero Knowledge Proofs and the Blockstream Satellite so enjoy the show, and don’t forget to share this conversation with evey bitcoiner you know.
