Co-creator of the Lightning Network, inventor of DLCs, and author of Utreexo—Tadge Dryja is easily one of the most influential developers in Bitcoin’s history.
After co-authoring the Lightning Network paper in 2015—leading to the development of what is still easily the most well funded and widely adopted Bitcoin L2 in the world—Tadge continued with some of the most influential Bitcoin research in the world, including but not limited to:
Discreet Log Contracts or DLCs—the only tech currently usable for truly decentralized Bitcoin lending.
Utreexo—which compresses Bitcoin’s UTXO set, enabling syncing by devices as small as a mobile phone,
And most recently, his quantum-resistance focused proposal “Lifeboat,” which creates a path for quantum securing Bitcoin without the need for moving wallets or introducing new/experimental PQC into Bitcoin.
By far and away my favorite part of this episode was the incredible history of the development of Lightning and the characters involved. If you’re a Bitcoin history nerd, or generally want to understand some of the most influential technology in the space, this episode is not to be missed.
This episode is powered by:
-Best In Slot, the leading API for Ordinals and BRC20 data aggregation and indexing
-Spark, a statechains implementation leading the path towards institutional adoption of Bitcoin-powered payments
-Citrea, the leading Bitcoin Rollup technology and contributor to the BitVM alliance

There are few people as close to the frontlines of Bitcoin privacy as Cake Wallet COO Seth for Privacy. After cutting his teeth building for Monero, Seth turned his focus to Bitcoin in 2022, with the view that making Bitcoin more private would ultimately help more people than focusing on a smaller niche target group alone.
Isabel Foxen Duke sits down with [[alloc] init] co-founder Misha Komarov and Head of Protocol Research Clara Shikhelman to examine PIPEs, a cryptographic framework that utilizes witness encryption—a primitive long dismissed as purely theoretical—to unlock advanced Bitcoin programming without a soft fork.
The first fully specified post-quantum signature scheme for Bitcoin has been proposed to the Bitcoin mailing list.
To date, post-quantum Bitcoin discussions have largely centered on which digital signature schemes offer the strongest cryptographic security against a quantum adversary.
Paul Sztorc founder and CEO of LayerTwo Labs and author of Bitcoin Improvement Proposals 300 and 301 (Drivechains), has been one of Bitcoin's most persistent—and controversial—thinkers, advocating for merge-mined sidechains as a way to dramatically expand Bitcoin's functionality while preserving the security of the base layer.
