As declared in Zcash Foundation`s post on the development, the hard fork is to strenghthen the protocol for additional upgrades to the network, for instance replay protection, versioning, a transactional expiry feature, and as yet undetermined changes.The customers will be demanded to install the upgrade after the software is carried out.
The protocol assists for seamless network updates in the future, such as the much-awaited Sapling protocol designed to raise network scalability and speed. Zcash claims the forthcoming update is well-gained by significant third parties like Binance, Gemini and BitFinex, who will “substantially support” Overwinter. The foundation is also continually reviewing the list of third parties as the entities confirm their involvement.
Theoretically, the network risks a blockchain split if any members of the community disregard the need to update the system and keep on with the old versions of Zcash. While Overwinter is low on features, it is important to the broader network strategy as further capabilities depend on the Overwinter update.
It`s worth to note that the friction is already happening in some places. On June 20, 2018, D. Jane Mercer, the developer of the ZCash Windows wallet, WinZEC, threatened to stop all coding activities as the network the Zcash Foundation failed to fund his work. The community members nevertheless promptly donated funds to his wallet address.
For miners running Zcash nodes, the official software has been updated to automatically update to the latest software after block 347,500 is mined. However, if automatic updates are disabled, miners stand to can miss the new code. Zcash Foundation asks the users to abstain from using their wallets at least an hour before the scheduled update.
