People don't understand the sheer volume of what is shipping in Zcash 2026. Just on the protocol side - Quantum Recoverability - New shielded pool w/ Recursive ZKPs - Nullifier state growth eliminated - Proof aggregation w/ miners - On-chain Privacy preserving fee markets - Most private token holder vote ever - Fully killed shielded sync, while letting you sync from chain - Seemless, private onboarding - PQ Privacy - 3x block time speedup - 50x TPS raised - DOS vector fully eliminated - PIR to eliminate spendability delays - PIR to solve PQ addresses - PIR to eliminate lightwalletd privacy leaks

Dev (@zkDragon) and I were talking about the near-future roadmap of quantum resilience in Zcash when these new papers dropped. His team has been working to bring ML-KEM and PIR into Zcash's payment protocol, for PQ privacy!

Sean Bowe (@ebfull) and Dev (@zkDragon) recently did a whiteboard session to discuss Zcash's post-quantum roadmap: recoverability very soon, using PIR w/ the Tachyon upgrade to achieve full PQ privacy, and setting the stage for PQ soundness alongside major scale improvements.

We've been careful and thoughtful about deprecating old shielded pools. Sprout is almost 10 years old and is on the way out. Quantum recoverability means Sapling is next, and the long but necessary process must start now.

@zodl_co onboarding getting better and better! No more shielded sync when making a new wallet github.com/zcash/zcash-an… (By @czarcas7ic )

Zcash is making its most crucial components private against quantum adversaries, using cryptography that we previously hadn't dreamed of shipping in a cryptocurrency. In parallel, almost a year of design in quantum recoverability is about to pay off in our next wallet upgrades.

Zcash Network State. @zkDragon on the architecture of freedom. 100+ builders and creators. $10k+ in ZEC prizes. Onward.

@jswihart congrats to the team! 🔥

Zcash Open Development Lab (ZODL) has secured over $25 million in funding from a16z, Paradigm, Winklevoss Capital, Coinbase Ventures, Cypherpunk Technologies, Maelstrom (family office of Arthur Hayes), Chapter One, David Friedberg, Haseeb Qureshi, Mert, Balaji and others. If you aren’t familiar, Zcash Open Development Lab (ZODL) is the team formerly known as Electric Coin Company (ECC), the group that launched Zcash, and the creator of @zodl_app. The name is new, but our team has been building Zcash for a decade. A couple of years ago, my team and I set out to change the trajectory of Zcash with an uncompromising focus on the user experience for shielded ZEC. We released Zodl (then called Zashi) and have never looked back. The release of the normie-friendly wallet was the first step. Then came integrations with partners like Flexa for retail spending and Keystone for cold storage. Most recently, we worked with the NEAR team to unlock ZEC swaps through NEAR intents. It worked. The proof is in the numbers. The wallet has driven adoption of the Zcash shielded pool by over 400%, and facilitated more than $600M in ZEC swaps since October. Now is the time to build on that momentum and accelerate. In addition to Zodl, we are building Zallet, a full node wallet that will also underpin new desktop software. Ultimately, we intend to deliver a private, decentralized financial system as an alternative to legacy institutions. This funding allows us to bring these ambitions to life, without relying on Zcash dev fund grants to get there. I’m grateful for these investors who are partnering with us. These are exciting days for the ZODL team and Zcash more broadly. We’re in the dawn of a new era. We will get ZEC in the hands of billions. Download at zodl.com Onward.

Fun conversations on scaling privacy and getting post-quantum!

Zcash coin holders made their priorities clear: scaling (Tachyon) and post-quantum readiness. @zkDragon joined me for a whiteboard session to discuss how we deliver both. 0:00 - Intro 0:43 - What it takes to scale Zcash 16:40 - Rough timeline on scaling 19:15 - What it takes to go post-quantum 32:23 - Rough timeline on going post-quantum

Interpretation of the Zcash coinholder sentiment collection... (My personal view is that if coinholders strongly oppose a change, it's *really* hard to argue we should do it anyway.) 1. ZSAs are in bad shape. There is basically no support from coinholders, and I'm not sure there's enough enthusiasm elsewhere to overcome this. I'm personally not bullish about ZSAs for numerous technical reasons. I think an argument still needs to be made for including this feature in the protocol. 2. NSM (modulo fee burning) seems unpopular with coinholders too. My guess is that anything that touches this issuance gives off bad vibes regardless of its merit. I think *because* it touches issuance we should be even more deferential to coinholders. 3. Fee burning seems fine. 4. Memo bundles are broadly disliked from coinholders. Personally I don't like these. It moves us in the wrong direction: memos are not sustainable / scalable in their current form, and we shouldn't be encouraging people to use them in ways we didn't originally anticipate. I appreciate the careful attention to detail and effort put into the ZIP though! 5. Explicit fees seem fine. 6. Sprout removal seems to have more opposition than I expected. We really need to propose this to the community again, perhaps next time with a more clear timeline/warning process. Sprout users are not paying for the ongoing burden that the Sprout pool has on the maintenance of the protocol, and the pool is nearly abandoned. 7. Tachyon has fantastic support from coinholders and from most others that were polled too. Thank you! Making progress on scalability seems very important to ZEC holders and most Zcashers I've talked to. I believe the results show there is a mandate to making progress shipping a shielded pool on mainnet even without wallet support, which is how our other pools have previously been shipped. I think this kind of aggressive deployment strategy is essential to making meaningful progress on scale. More generally, I think this bodes well for other scaling-related objectives being developed such as the ideas coming from the @zkDragon camp (which I think will be vital for Tachyon's success), and so those should feel a similar amount of support here. Take this one with a grain of salt, since Tachyon is my pet project! 8. STARKs haven't quite been sold to the community yet. I haven't seen much enthusiasm for them on a technical level from other protocol devs due to concerns like security levels. Let's maybe keep iterating on this, it doesn't seem dead but it seems like an uphill climb. 9. Dynamic fees don't enjoy much support and there's genuine concern/skepticism about the mechanics design of them (as proposed.) I agree, this needs more work. 10. No real enthusiasm for consensus accounts. This is a weird one, I don't know what to think about it yet. 11. Quantum recoverability is pretty solid across the board. Great work to the ZODL crew on this.
