I'm really excited about this vision. ACK.
These are ambitious goals but all doable; we've done far more in much less time, just in the last six months alone. We need to work this hard for Zcash to win. And because it's worth doing, it'll be fun too!
A vision for Zcash L1, January 2027
- Scale: Achieve 200 shielded TPS
- Uses Tachyon & a 4x block size increase
- Post-Quantum:
- Unconditional Post-quantum Privacy live
- PQ Transparent
- Sapling deposit disable date set, users must go QR
- Longevity: Software wallets and hardware wallets stop breaking every NU.
Hope the community rallies around landing it forum.zcashcommunity.com/t/v… !
The folks at ZCG have voted and agreed to withdraw their (IMO, misguided) reform proposal. This effectively leaves the compromise that @zooko and I negotiated and which has received most cross-institutional support in the community.
Thanks ZCG!

Here's the compromise we struck:

New Zakura Release: 1.8.0
This release improves security by removing even more unnecessary code dependencies. Performance around block propagation, processing and mining flows has been enhanced as well. Read on to find out how we benchmarked:

We've done a very detailed benchmark of production Zcash node behavior. Zakura is crushing it in every dimension, and this release solidifies it. 😁

GGuy, one of the members of ZCG, has voiced his support for our proposed ZCG reform ZIP. Thank you, GGuy!

Zakura is dominating. There isn't a single level of the Zcash stack where it's not currently the leader in progress. Cryptography, security, performance, everything.
Enjoy the monthly recap:
Please also read @zooko's thread about this compromise proposal!
Huge thanks to @ZcashFoundation for organizing Zcon!
I wasn't able to attend, but I would have been happy to in other circumstances. IMO:
* stop organizing community-wide events in dangerous countries
* try to avoid announcing the speakers ahead of time
This is great! Sapling needs to be turned off for a while, the same way Sprout was deprecated. It's not really possible to make Sapling quantum-recoverable, so folks need to move their funds to the modern Ironwood pool.
Made a draft ZIP for turning Sapling withdraw only: github.com/zcash/zips/pull/1…
Stats at a glance:
- 1.2% of non-mining pool transactions were Sapling
- Of those, they are predominantly withdrawing
Lets get everyone into Quantum Recoverable, Formally Verified pools!
It's time to turn off the ZCG funding stream.
ZCG has over $125M in funding, and will receive millions more before the spigot is turned off. The program was never designed to handle this amount of funding.

Lots of people missed this, I think. Soon, @vizorwallet will have quantum-unlinkable swaps, and it doesn't need to wait for a network upgrade. Yet another way it leads the privacy frontier of Zcash right now.
If your Zcash wallet uses NEAR Intents, each swap you make adds your shielded address to a public ledger. A quantum computer could use this to link all your payments that share the same key.
In Vizor, each swap will get its own key to prevent this.

Wife switched to @vizorwallet because she could have a cat in a hoodie as her wallet avatar. Then she stayed because it was absurdly fast at everything.
NU7 is finally activating on Zcash! Zakura 1.7.0 activates it on height 3543405, which is the evening of November 5 for us Americans.
Blocks will occur three times faster in Zcash. Other changes like NSM funding and retiring the Sprout pool appear in this upgrade as well.
New Zakura Release: 1.7.0
This release activates NU7 on Mainnet in ~15 days. 🎉

Zakura's wallet and cryptography support libraries are integrating @ValarGroup's PIR-based tech that Tachyon depends on for its payment protocol, and some of it is immediately useful today!
Any wallet can use or even fork this code: it's free, open-source, and permissionless.
Post-quantum unlinkable swaps for Zcash, no network upgrades required.

Similarly, as we blogged about earlier this month the Zakura Common codebase is switching to a cryptography backend that is used for Tachyon. Goal is to ship this in Common 1.8.0!
tachyon.z.cash/blog/integrat…
Make your NEAR swaps post-quantum unlinkable with Zcash's current protocol.
Uses a new trick that adds a kind of "diversification" but instead of for addresses, it's for viewing keys! Using the PIR tech that @adamleetucker17 et al. have been building at @ValarGroup.
Adam also wrote an article for @ZakuraZcash's engineering blog about the technique:

This one is due to @alex_xiong_, a novel trick for decomposing large multisets for our specific purpose. Really simplified Tachyon's design.
