Explaining SNARKs Part II: Blind Evaluation of Polynomials
<< Part I In this post, we recall the notion of a polynomial, and explain the notion of “blind evaluation”
BLS12-381: New zk-SNARK Elliptic Curve Construction
Our team is continually working to improve the security, performance and usability of our privacy-preserving shielded transactions. As we mentioned
Explaining SNARKs Part I: Homomorphic Hidings
Constructions of zk-SNARKs involve a careful combination of several ingredients; fully understanding how these ingredients all work together can take
Lessons From The History Of Attacks On Secure Hash Functions

How Transactions Between Shielded Addresses Work
In ‘Anatomy of A Zcash Transaction’ we gave a general overview of Zcash Transactions. The purpose of this post is
Zcash Parameters And How They Will Be Generated
At its core, Zcash’s privacy technology relies on a novel cryptographic tool called a zkSNARK – a small zero-knowledge proof
Pairing cryptography in Rust
Pairing cryptography is an exciting area of research, and an essential component of Zcash’s zkSNARKs — proofs that transactions are
Fixing Vulnerabilities in the Zcash Protocol
Intro by Zooko I’ve worked in cryptography, information security, and digital money for half of my life (20 years, but
