During extensive testing of the ZenCash node software prior to launch our developers and community members identified an intermittent issue with transaction completion. Some of the transactions completed successfully on the testnet, and others did not.
Through working to identify the issue they discovered that one of the changes made to prevent transaction replay between the ZenCash and Zclassic blockchains caused the problem.
The code changes required to fix the intermittent issue require more time than we have before launch tonight.
Because of this issue, the ZenCash core team decided to delay the launch by 7 days, to May 30th. This decision was not made lightly, but due to the nature of the launch, where 1,375,000 ZenCash tokens will immediately come into existance, we decided it was more important to be 100% certain the ZenCash blockchain, node software, and wallets are working properly before launch.
Thank you very much to the ZenCash community developers who have worked diligently these last few days to troubleshoot and identify the issue.
Thank you to everyone that has supported ZenCash so far, and we look forward to a launch in 7 days.
