Electrical Coin Co. (ECC) has been working since June to resolve Zcash pockets efficiency points which can be affecting customers of third-party apps Edge, Nighthawk, and Unstoppable.* All three of those cellular wallets make the most of the ECC SDK.
Our engineers have made progress, nonetheless, work stays — together with additional updates to zcashd, lightwalletd, the ECC pockets SDKs, and the ECC prototype pockets — to completely restore good consumer expertise within the impacted apps.
Fixing these points is our No. 1 precedence, even taking priority over our long run roadmap. Internally, we’re calling this “Emergency Mode.”
The syncing drawback
Beginning in June 2022, the Zcash community started experiencing an enormous improve in shielded transaction quantity. This extra community load brought on a “knowledge pileup” that prevented some wallets from having the ability to sync in an affordable period of time. (The present pockets sync course of requires scanning the complete blockchain earlier than funds can be found to be spent.) If a pockets gained’t sync, a consumer can’t entry or spend their funds.
It’s an advanced problem to handle, and at minimal, it requires growing and implementing (1) a sooner algorithm that doesn’t require a linear sync of all blocks on chain and (2) tooling modifications that may give customers the power to spend funds with out having a completely synced chain. As talked about, the answer includes modifications to each part within the shielded cellular pockets stack: zcashd, lightwalletd, the ECC pockets SDKs, and the ECC prototype pockets.
What we’ve accomplished thus far
Inside weeks of figuring out the issue, ECC launched two updates to zcashd that resolved full node points, and work was underway on the SDKs. In October, we launched zcashd 5.3.0 to repair out-of-memory points, however additional public releases particularly related to those syncing points have been delayed, as ECC engineers have been pulled off process to construct zcashd 5.3.3 and 5.4.2 — essential updates that remediated vulnerabilities inherited from Bitcoin Core.
Right here’s a abstract of what we’ve accomplished, thus far, to handle pockets efficiency points:
Launched zcashd 5.1.0 and 5.2.0 in July to handle efficiency in full nodes
Launched zcashd 5.3.0 to repair various intermittent out-of-memory points
Accomplished many of the code updates and testing for zcashd 5.5.0, which implements price modifications. Be aware: customers ought to have the power to spend funds with no full pockets sync upon the discharge of zcashd 5.6.0.
Accomplished a portion of the back-end work required to help the following launch of the iOS and Android SDKs, which can embrace the primary part of an improved sync functionality.
Exiting Emergency Mode
Our prime precedence is making certain customers can entry and spend their ZEC (Zcash cash). That is elementary to our mission of financial freedom and a requirement for real-world non-public digital money.
Pace and reliability are additionally essential to Zcash consumer expertise, so we’re constructing updates that may permit customers to obtain and spend new incoming funds sooner,** and we’re implementing options that present visibility on syncing progress.
Solely after these capabilities are delivered — and once we’re assured that wallets are usually not being impacted by frequent crashes or inconsistent conduct — will we think about exiting Emergency Mode and widening our focus to incorporate different initiatives.
The desk beneath represents an estimated launch schedule to handle the pockets syncing points. Every launch is slated for supply inside a half-month window to permit for dozens of inherent dependencies. Interim releases could happen based mostly on particular necessities or dependencies all through this course of. Model numbers listed may additionally change based mostly on emergency or different unplanned impacts.
It’s necessary to notice that after these releases are made obtainable, third-party builders might have various days or perhaps weeks to implement and take a look at.
Fund availability enchancment will present the power to spend funds earlier than a pockets is absolutely synchronized.
Whereas this launch may have no rapid constructive impact on the pockets consumer expertise, it is a obligatory step towards exiting emergency mode.

Customers is not going to see the modifications to the UX till the SDK replace 0.6 (outlined beneath) goes out.
Second half of Might 2023Mobile SDK updates 0.6 (iOS & Android)This replace will embrace help for third-party app entry to fund availability and improved sync capabilities.
As soon as this replace is dwell, it will likely be as much as the person pockets builders to combine the brand new options into their utility, which can allow customers to entry their funds with out points and enhance the general Zcash consumer expertise. This may finish the emergency mode.
* Based mostly on neighborhood suggestions, Ywallet has been working properly and seems to be unaffected by excessive transaction load on the community.
** The velocity benchmark we’ve set for downgrading from emergency mode is {that a} typical Zcash consumer can obtain and spend funds at a price of a month’s price of transactions in a single hour. This isn’t an ideal measurement (use circumstances can fluctuate wildly), neither is it our finish purpose (we all know an awesome consumer expertise calls for extra), however we imagine it’s necessary to set a reference purpose for inner and neighborhood alignment. Future velocity enhancements might be deliberate as soon as the essential points are resolved.
