## Reducing Shielded Proving Time in Sapling

Since the successful Sapling network upgrade, we have already seen an increased adoption of shielded addresses in the Zcash ecosystem. […]

As we approach Zcash’s second birthday, it’s fitting to look back at the origins of this little experiment. And who […]

zk-SNARKs – the zero-knowledge proofs at the core of Zcash – require a parameter generation ceremony to take place for […]

As a science-focused team, ensuring the security of the Zcash protocol and the users of the network is a natural […]

Last year, I created a project called pay-to-sudoku which was the world’s first implementation of a zero-knowledge contingent payment (ZKCP). […]

<< Part VI In Part VI, we saw an outline of the Pinocchio zk-SNARK. We were missing two things – […]

<< Part V In part V we saw how a statement Alice would like to prove to Bob can be […]

<< Part IV In the three previous parts, we developed a certain machinery for dealing with polynomials. In this part, […]

<< Part III In this part, we build on Part II and III to develop a protocol for verifiable blind […]

Bellman is a Rust-language library for building zk-SNARKs — small, cheap-to-verify zero-knowledge proofs of arbitrary computations. The goal of bellman […]

<< Part II In Part II, we saw how Alice can blindly evaluate the hiding :math:`E(P(s))` of her polynomial :math:`P` […]

<< Part I In this post, we recall the notion of a polynomial, and explain the notion of “blind evaluation” […]

Our team is continually working to improve the security, performance and usability of our privacy-preserving shielded transactions. As we mentioned […]

Constructions of zk-SNARKs involve a careful combination of several ingredients; fully understanding how these ingredients all work together can take […]

The SHA-1 hash function, which has long been considered insecure, is now officially broken as of yesterday. Given the renewed […]

As a security-focused team, made up of world-class talent, we prioritize the security of Zcash users. True security comes from […]
