For our first episode, we talked to Bitcoin Core contributor Pieter Wuille.

Pieter has been a Bitcoin protocol developer and contributor to Bitcoin Core since 2011. In that time, he’s authored or contributed to some of the most important developments, including segwit, bech32, libsecp, HD wallets, schnorr and taproot, and many others.
