Last updated July 24, 2019 – Please update to ZEN software (2.0.18) now!

All exchanges, mining pools, node operators, and full node wallet users must upgrade to ZEN 2.0.18 prior to block #555555, which occured on the 23rd of July

ZEN 2.0.18 replaces the current version 2.0.17, which has deprecated (no longer runs).

The focus of this version is the RPC method ‘getblockfinalityindex’ update. This update informs the user after how many blocks a transaction can be considered safe without the possibility of being reverted. In addition, the update adds a check block at height safety control for orphaned blocks, preventing mistakes in raw transaction creation.

The next software upgrade (2.1.0) will bring the full implementation of Sapling and other features to be announced. The release was postponed due to a known denial of service bug in upstream Sapling.

Please update the following software now:

ZEN 2.0.18: Download Alternatively, the new 2.0.18 version is available through the APT repository, see instructions HERE

Swing wallet: Download

Sphere by Horizen: Download See upgrade instructions and changelog HERE

What happens if you did not upgrade before the 23rd of July?

Pool operators: ZEND will not work and thus you will not be able to mine ZEN until you upgrade to ZEN 2.0.18.

Node operators: ZEND will not work and thus you will not be eligible to earn ZEN until you upgrade to ZEN 2.0.18.

Full node wallet users (Swing wallet, Sphere by Horizen): you will not be able to access your funds until you upgrade to the latest wallet version.
