History of ZKProofs | With Eli Ben Sasson
The History of Zero-Knowledge Proofs | with ZK “Godfather” Eli Ben Sasson
In 2013, computer science professor Eli Ben-Sasson presented his research on zero-knowledge proofs at a small Bitcoin conference outside of Standford University. The presentation immediately sparked interest from Bitcoin Core developer Greg Maxwell—leading Eli into over a decade of sustained work advancing ZK-based solutions for blockchain scalability and privacy.Today, zero-knowledge proofs are widely considered some of the most powerful and promising cryptographic primitives for scaling—with their full potential for Bitcoin simmering just beneath the surface of active development.This episode shares Eli’s early discussions of ZKPs for scaling, the use of proofs in privacy-enhancing technologies like Zcash, the explosion of ZKPs for Layer 2s on Ethereum… and his recent return to exploring ZKPs for Bitcoin.
This episode nods heavily to other contributors in the space—including Adam Back, Jeremy Rubin, Robin Linus, Ethan Heilman and others. Thanks in advance to Nathan Jeffay and the Starkware team for making this episode possible!
