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.

In the main Zcash network, the Sapling protocol was activated, which is necessary to perform secure transactions and increase blockchain performance.

The update is activated at block 419200. It, in particular, will reduce the time for processing transactions up to 90%, as well as significantly reduce the requirements for the amount of memory required to perform secure transactions. Sapling activation will also make it possible to use lightweight clients for secure transactions, and not just full nodes.

Immediately after activating Sapling, users of the zcashd client have access to addresses of a new type. Currently, funds cannot be transferred from protected old addresses to new ones without disclosing the amount of the transaction. This makes it possible to audit the monetary base of ZEC relating to protected addresses. The Zcash team is currently working on creating a tool to automate the movement of funds without compromising user privacy.

The Zcash blog also says that Sapling activation is essentially a “rebirth of cryptocurrency” because it takes the project a step closer to mass adoption as an open and confidential payment system.
