Zen 2.0.14

What is Zen?

A globally accessible and anonymous blockchain for censorship-resistant communications and economic activity.

Upgrading from 2.0.11 source

To upgrade from any version prior to 2.0.14 you will have to re-clone the repository, the ZencashOfficial/zen repository was replaced by a new repository based on Zcash upstream with a different commit history, merging/pulling is not possible without issues. Assuming your current repository is stored at ~/zen, do the following to upgrade:

# if you don't want to keep the old src around
rm -r ~/zen
# or if you do want to keep it
mv ~/zen ~/zen_archived
git clone https://github.com/ZencashOfficial/zen.git
cd ~/zen

Now continue with building from source.

About

Zen is a platform for secure communications and for deniable economic activity. Zen is an evolution of the Zclassic codebase aimed at primarily enabling intriniscally secure communications and resilient networking.

This software is the Zen client. It downloads and stores the entire history of Zen transactions; depending on the speed of your computer and network connection, the synchronization process could take a day or more once the blockchain has reached a significant size.

Security Warnings

See important security warnings in doc/security-warnings.md.

Zen is unfinished and highly experimental. Use at your own risk.

Where do I begin?

  • The easiest way to get started is to download one of the available graphical wallets from zensystem.io
