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:

New Zakura Release: 1.7.0
This release activates NU7 on Mainnet in ~15 days. 🎉

Scaling Zcash to Visa-level throughput requires a next-generation networking stack. We're excited to share P2Pv2, which you can try out today in Zakura!
Here's our plan for quantum-safe, unlinkable, rotating taddrs. Possible with Zcash, today.
While others are worrying about the viability of rotating transparent addresses, we're already solving linkability.

We've created an NU7 dashboard so you can monitor Zcash's next network upgrade live, along with a testnet faucet and a simple guide for participating with Zakura.

New Zakura Release: 1.5.0
Miners benefit especially from this release: faster block commits, steadier mining templates, less work during template construction, and better handling of edge cases. Experimental P2Pv2 also gets reliability improvements.

We're happy to see Zakura's optimization work being adopted and fortified elsewhere in the Zcash ecosystem! We strongly advocate permissive, open-source licenses for Zcash cryptography and protocol code.

NU7 is coming! All of the Zcash development orgs have come to unanimous agreement about the contents and timeline of our next network upgrade, following the sentiment collection results earlier this week.
Activation approximately November 5.

Thanks to Tachyon's @MariusMargulus, the new zk-SNARK prover in Zakura (and also in @vizorwallet) is the first Zcash prover with a machine-checked Lean proof of statistical honest-verifier zero-knowledge.

Zakura Common 🌸 is a new cryptography stack for Zcash, built to make shielded operations significantly faster.
Wallets can integrate its libraries to improve UX with faster proving, verification and syncing!

New Zakura Release: 1.4.0
Latency reductions across the board. Faster block propagation. Fast proving for block templates that use shielded coinbase (for mining pools).
And on an iPhone 17, proving is now 21x faster overall since Zakura started!

Behold, @zkDragon's legendary tour of Zcash's cryptography code.
675% faster in 24 days, on a desktop. 2-3x those gains on recent iPhones.
The COINBASE_MATURITY rule applies to transparent coinbase outputs, but not to shielded outputs. You can spend your newly mined ZEC immediately -- as long as you mine to a shielded address!
Zakura makes that way more practical by speeding up shielded coinbase getblocktemplate!

it takes a while to safely accelerate such an important and established project.
We MUST be conservative and careful.
While 25s is still painfully slow, the rate of improvement is the important thing. We are clearly getting better at shipping weirdly reliable and performant software.
Much lower is very possible given the appetite.
we simply need to stay hungry. Zcash can and should have SoTA everything.

It looks real. @ZakuraZcash crushed the orphan rate for Zcash.
Saving the miners ~$1,000 a day in wasted electricity...
We need more nodes! All the relevant costs (cpu, ram, disk space, bandwidth) have never been cheaper for zcash!
Run a @ZakuraZcash node off a pruned snapshot today!
New Zakura Release: 1.3.0
This release integrates our recently-announced Zakura Common cryptography stack. It also introduces a new consensus engine for our P2Pv2 stack which will improve Zcash network security and throughput.

We've upgraded CipherScan's memo decryption using @ZakuraZcash Commons.
1.5x faster trial decryption, fully client-side, your viewing key never leaves your browser.
