Ariel Gabesant's Journey into Cryptography
Ariel Gabesant, a cryptographer, shares his early journey and interest in cryptography. Initially skeptical and viewing cryptography as negative, Ariel's perspective changed when he fell in love with Bitcoin after reading its white paper. Inspired by his math background, Ariel saw zero-knowledge proofs and SNARKS as the best way to contribute to the Bitcoin world. He collaborated with Ellie Ben-Sasson to work on developing and implementing Starks. Ariel eventually joined Zcash, focusing on the Trusted Setup Ceremony and contributing to the sapling upgrade. He later discovered a bug in the ZK-SNARK protocol and proposed a re-randomization fix. After leaving Zcash, Ariel joined Protocol Labs and became involved in the Filecoin project, working on proofs of replication. He also explores other promising cryptographic techniques such as RSA accumulators and KZG polynomials.
