<< Part I In this post, we recall the notion of a polynomial, and explain the notion of “blind evaluation” of a polynomial, and how it is implemented using Homomorphic
Our team is continually working to improve the security, performance and usability of our privacy-preserving shielded transactions. As we mentioned in our near future priorities blog post, we are working
Constructions of zk-SNARKs involve a careful combination of several ingredients; fully understanding how these ingredients all work together can take a while. If I had to choose one ingredient whose
The SHA-1 hash function, which has long been considered insecure, is now officially broken as of yesterday. Given the renewed interest in hash function collisions, I’d like to point out
As a security-focused team, made up of world-class talent, we prioritize the security of Zcash users. True security comes from empowering users directly, and to that end, we will always
At its core, Zcash’s privacy technology relies on a novel cryptographic tool called a zkSNARK – a small zero-knowledge proof that is cheap to verify. Zcash will be the first
Our mission is to make the first open financial technology with zero-knowledge privacy, for every person in the world to use. To that end we are commissioning multiple security audits
Pairing cryptography is an exciting area of research, and an essential component of Zcash’s zkSNARKs — proofs that transactions are valid without requiring users to reveal private information. Earlier this
Today, we deployed a new alpha release of the Zcash reference implementation, v0.11.2.z3, to the testnet. The new release includes the following changes [1]: We’ve implemented the Zcash protocol in
Intro by Zooko I’ve worked in cryptography, information security, and digital money for half of my life (20 years, but who’s counting?), and I’ve never worked on a cryptosystem as
There are a lot of cryptographic challenges to making a fully secure and reliable open financial system. Our current top priority in the Zcash development process is to securely generate
