During the course of testing NU5, a consensus bug emerged that caused the testnet chain to fork. The ECC Core team found it quickly and subsequently identified and implemented a fix to be included in our upcoming Zcashd release 4.7.0. Out of an abundance of caution, and to ensure that the ecosystem of wallets, exchanges and miners have sufficient time for integration and testing, we are delaying the release of NU5 until May.
ECC has a record of delivering safe and secure technology. This time will be no exception. The ZEC asset is built on sophisticated cryptography, which requires maximum due diligence from our team, to optimize user experience and to protect users.
The NU5 mainnet activation block height will be set in Zcashd 5.0.0, which is now planned for release approximately April 21. We anticipate NU5 will activate about four weeks later, in mid to late May. We are also working on an updated schedule for the mobile SDK and ECC reference wallet.
We’d like to thank the community for their patience during this process. Please know that we are working tirelessly to deliver this game-changing innovation — for economic freedom, for all.
