Eleven months ago we discovered a counterfeiting vulnerability in the cryptography underlying some kinds of zero-knowledge proofs. This post provides details on the vulnerability, how we fixed it and the steps taken to protect Zcash users.

We’re happy to announce the release of Zcash 2.0.0, the first Sapling-compatible version of the Zcash node software! Sapling Activation […]

Zcash’s next major upgrade, codenamed Sapling, will be activated later this year. One of our final goals before activation is […]

The next major upgrade of Zcash, codenamed Sapling, is scheduled to activate in October 2018. The specific block height has […]

Zcash’s shielded transactions rely on zk-SNARKs — small, fast-to-verify zero-knowledge proofs of arbitrarily complicated statements. These proving schemes rely on […]

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

Zcash’s next major upgrade, codenamed Sapling, will feature a set of groundbreaking performance improvements for our shielded transactions. In the […]

Zcash’s next major protocol upgrade, codenamed Sapling, will feature a number of improvements to the performance, security and usability of […]

Today we’re announcing the release of Zcash 1.0.10-1, a hotfix release that all users are encouraged to upgrade to, especially […]

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

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