The first ever hard fork of privacy-oriented cryptocurrency Zcash is little more than a day away. The upgrade is called Overwinter and it will take place at block 347,500.
What is Overwinter?
Overwinter is set to become the very first hard fork for Zcash. Its purpose is to fortify the existing protocol for future upgrades. Designed to activate at block 347,500, which, assuming 150 seconds/block rate, should happen on June 26th, the upgrade will require all users to update the existing software.
