Podcasts: TLS75: John Light on Validity Rollups on Bitcoin, ZK-proofs, and the Lightning Network 🔗 1 year ago

John Light is a Bitcoin researcher who recently published a paper exploring how Validity Rollups might work on Bitcoin.

In our conversation, we first explored what zero-knowledge proofs and rollups are, we discussed the different ways in which rollups could be implemented, the risks and rewards to implementing rollups on Bitcoin, and the ways in which rollups and the Lightning Network could be complementary to each other.
