All mining pools, node operators, and Swing wallet users must upgrade to ZEN 2.0.15 prior to block 392512 which will occur around midnight on October 10th.

ZEN 2.0.15 replaces the current version 2.0.14, which is set to deprecate (no longer run). The major focus of this version is the new 51% attack prevention feature.

UPDATES ON ZEN 2.0.15

  • 51% attack prevention code
  • Update RPC commands/thread names/messages with new Horizen name
  • Update Horizen logo
  • Fix erroneous log messages on wallet rescan

WHAT HAPPENS IF YOU DO NOT UPGRADE BEFORE OCTOBER 10TH?

  • Miners and node operators: ZEND will not work and thus you will not be able to earn ZEN until you upgrade to ZEN 2.0.15
  • Swing wallet users: You will not be able to access your funds until you upgrade to the latest Swing wallet version.

Zen version 2.0.15 is scheduled to be released on September 27th, 2018 to address the upcoming deprecation of the current version on October 10th, 2018.

The release includes the new 51% attack prevention code which has been successfully tested and works as expected. It also includes some backend rebranding updates. Zen 2.0.14 will shut off at block height #392512 around October 10th (near midnight UTC or shortly after) automatically.

All node operators, exchanges, and anyone running the full version will have to update to zen 2.0.15 before then. The new 2.0.15 version will be available at https://github.com/ZencashOfficial/zen/releases/latest on September 27th by end of the day. Updated versions of the Swing wallet will be available several days after.

Update instructions for node operators and miners will be provided soon.
