News and notes about Electric Coin Company and its work on Zcash

Electric Coin Co. (ECC) has been working since June to resolve Zcash wallet performance issues that are affecting users of third-party apps Edge, Nighthawk, and Unstoppable.* All three of these mobile wallets utilize the ECC SDK.Our engineers have made progress, however, work remains — including further updates to zcashd, lightwalletd, the ECC wallet SDKs, and the ECC prototype wallet — to fully restore good user experience in the impacted apps.

NU5, the first major upgrade since November 2020, includes the launch of the Orchard shielded payment protocol, utilizing the Halo proving system to remove reliance on complex setup ceremonies.

The 5.0.0 release supports NU5 activation on mainnet, which will occur at a block height of 1687104 (May 31st), following the targeted EOS halt of our 4.6.0-2 and 4.7.0 releases on May 16th. Release binaries will be available later today and instructions on how to install can be found on our download site.

Release 4.7.0 marks a major milestone on the path to NU5.

4.6.0-2 is primarily a bugfix release that also bumps the End-of-Support height to May 16th. It backports bugfixes from v4.7.0-rc1.

We had many successes in 2021 across all of our engineering-related teams including Core, Mobile, and DevSecOps, a team comprising what was previously the separate DevInfra and Security teams. These successes included the regular cadence of releases as well as breakthrough cryptographic research, developments to move the shielded wallet ecosystem forward, operational enhancements and advancements, and a continued demonstration of our commitment to security best practices, ensuring safe and secure releases and network upgrades. 

TL;DR: The 4.5.0, 4.5.1, and 4.5.1-1 zcashd nodes will reach End of Service on or about January 10th, 2022. Prior to that time, miners must upgrade to 4.6.0-1 and all other testnet and mainnet nodes should upgrade to either 4.6.0 or 4.6.0-1.

TL;DR: The 4.5.0, 4.5.1, and 4.5.1-1 zcashd nodes will reach End of Service on or about January 10, 2022. Prior […]

As part of our due diligence, we embarked on sentiment gathering, market research and economic modeling to better understand the possibilities of ZSAs and tradeoffs of different approaches.
