The Untold Story of the Lightning Network | with Tadge Dyja

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.
