Back in October, Josh Swihart 🛡 explained why Zcash exists and why it started with Bitcoin: "Zero knowledge cryptography had been around for 30 years. Theoretical math. Academic. No practical application." "Satoshi wanted privacy for Bitcoin. Hal Finney was working on it. Scientists at Johns Hopkins, MIT, Technion figured...

VanEck CEO Jan van Eck on CNBC: “There’s something else going on within the Bitcoin community that non-crypto people need to know about. And that is: ultimately, VanEck has been around before Bitcoin. We will walk away from Bitcoin if we think the thesis is fundamentally broken. We don’t right now, but you always have to look at the underlying technology and the crypto. What the Bitcoin community has been asking itself is: Is there enough encryption in Bitcoin, because quantum computing is coming? And secondly: Is there enough privacy in Bitcoin? And so a lot of Bitcoin OGs or maxis have been looking at Zcash. Zcash is a token. It’s sort of related to Bitcoin with a lot more privacy. The kind of garbage that we got about Bitcoin four years ago was: ‘It’s used for all bad illicit behavior.’ But now everyone kind of realizes that when you move money around on the Bitcoin blockchain, you can see it. You can see it move from one wallet to another. And a lot of people are looking for more privacy.”

"I run my company on Solana, but personally I hold Zcash" Mert explains why he personally holds Zcash ($ZEC), and why he doesn't see it as a competition: "Privacy is the last peeve. It doesn't really interfere with anybody else's goals, except maybe Bitcoin." "I still run my company on Solana. But personally, I hold Zcash, because what Solana aims to do is completely different from what Zcash does." "Same with all the major chains except Bitcoin." "Why would there be only one store-of-value money in a digital world? There's no reason to be zero-sum, especially now."

There have been whispers of Bitcoin hodlers swapping BTC for Zcash 🤔🔏 Why? Because some Bitcoiners want to be able to transact with more privacy. BUT Bitcoin can still have NATIVE privacy and scale. Eli Ben-Sasson | Starknet.io explains how ZK-proofs and OP_CAT hold the key 🗝️👇 We caught up with the 'Godfather of ZK' on Cointelegraph's Chain Reaction show this week for a deep dive into the promise of zero-knowledge technology for Bitcoin and beyond. Ben-Sasson, who co-authored the ZeroCash protocol whitepaper and helped found Zcash 🛡️, said that Bitcoin can still have native privacy and infinite scalability if developers can agree to reinstate OP_CAT, a Satoshi-era OP_Code that Bitcoin's creator disabled in 2010. It turns out that Zcash's resurgence in 2025 could be the catalyst for Bitcoin's privacy push. "I hope that one consequence of this would be that the Bitcoin community becomes more open to things like OP_CAT and OP_STARK so that it can have post-quantum security, best privacy, best scale and programmability for this beautiful hard asset that is Bitcoin." Ben-Sasson said. "The technology is ready. All you need is a soft fork adding nine lines of code that Satoshi actually introduced. It's called OP_CAT. It's very, very easy. If there's a will, there's a way. In this case, it's a very simple way to give all of that goodness to Bitcoin itself." You can watch our full conversation with Ben-Sasson in the 🧵👀📺

"Satoshi knew." a16z crypto research partner Ittai Abraham on how Bitcoin solved a 40-year-old academic problem, and how its creator knew it all along: "It actually took quite a few years for people to realize that this is kind of solving a Byzantine agreement problem… a very core academic problem that has been studied for 40 years." "In that sense Bitcoin is kind of this huge revolution in how to solve Byzantine agreement. In fact, if you look at early emails from Satoshi Nakamoto, he said the core technical aspect of Bitcoin is solving Byzantine agreement."

BITCOIN RAILS #69: ZERO-KNOWLEDGE PROOFS FOR POST-QUANTUM BITCOIN | with Benedikt Bünz 🔗 YOUTUBE: 🌿 SPOTIFY: While many Bitcoiners remain hopeful the network will embrace zero-knowledge proofs for protocol-level use cases, practical adoption has remained limited outside of BitVM and a handful of experimental proposals. Most of the world’s ZKP research has circled around Ethereum and other ecosystems, where significant resources have been dedicated to advancing these systems, particularly for scaling and privacy applications. One of the most notable contributors to this research is Benedikt Bünz ☕️ — professor of cryptography at NYU and collaborator of Dan Boneh, who together inarguably form one of the strongest blockchain-applied cryptography teams in the world. The pair recently announced they’ll be leading the new post-quantum cryptography unit localhost research — the first dedicated PQ research effort within a major Bitcoin development organization. With Benedikt leading the charge on the use of zero-knowledge proofs for post-quantum mitigation, the question emerges: will the post-quantum transition be the catalyst to finally bring zero-knowledge proofs to Bitcoin's core protocol? In more detail, Benedikt and I discuss: - Why ZKPs haven’t been widely adopted by the Bitcoin technical community — and why the threat of quantum computers may change that posture going forward - How ZKPs could be used for signature batching to address larger post-quantum signatures in Bitcoin’s post-quantum era - Why Bitcoiners will likely prioritize hash-based signatures as an initial post-quantum scheme — rather than more efficient but less proven alternatives (e.g., lattice-based) - How ZKPs have evolved over the last decade and may finally be ready for Bitcoin’s strict requirements around trust assumptions - Why Benedikt and Dan are teaming up with localhost research to create the first post-quantum cryptography unit within a major Bitcoin development organization + what they hope to accomplish This episode of Bitcoin Rails is brought to you by: LayerTwo Labs LayerTwo Labs — developing research, software, and technologies for scaling Bitcoin via the integration of Drivechains (BIP 300/301) Hashi on Sui — a primitive for executing Bitcoin DeFi transactions, without having to trust a federated bridge or other centralized entity BitBox BitBox — an open-source Bitcoin-only hardware wallet, with smooth UX and no compromises on security.

BITCOIN RAILS EPISODE #24: The History of Zero-Knowledge Proofs | with ZK “Godfather” Eli Ben Sasson In 2013, computer science professor Eli Ben-Sasson | Starknet.io presented his research on zero-knowledge proofs at a small Bitcoin conference outside of Standford University. The presentation immediately sparked interest from Bitcoin Core developer Greg Maxwell—leading Eli into over a decade of sustained work advancing ZK-based solutions for blockchain scalability and privacy. Today, zero-knowledge proofs are widely considered some of the most powerful and promising cryptographic primitives for scaling—with their full potential for Bitcoin simmering just beneath the surface of active development. This episode shares Eli’s early discussions of ZKPs for scaling, the use of proofs in privacy-enhancing technologies like Zcash, the explosion of ZKPs for Layer 2s on Ethereum… and his recent return to exploring ZKPs for Bitcoin. As always, you can view this episode on YouTube or Spotify via the linktree in my bio—YouTube link in comments as well.

Z Protocol: Why We’re Bullish on Zcash as a Engine of Satoshi Plus In an interview with WuBlockchain, Z Protocol Co-Founder Kieran Dennis stated that Zcash shares a foundational architecture with Bitcoin (UTXO and PoW), mapping perfectly onto the Satoshi Plus architecture. Zcash miners can dedicate their hash rate at zero cost to secure Z Protocol, and holders can earn staking rewards through a fully self-custodial model. Furthermore, Z Protocol leverages Zcash's cryptographic primitives, such as the shielded pool, to provide total privacy preservation for the cross-application AI agent experience.

👁‍🗨Not Dead Yet | S1E2 — Eli Ben-Sasson At long last, privacy is in vogue, particularly in crypto. Running parallel to the rise in interest has been the rise of Zcash 🛡️, now even with $ZEC treasury companies forming like Cypherpunk. In episode 2 of Not Dead Yet, Robert Baggs speaks with Eli Ben-Sasson | Starknet.io. Eli is a long-time researcher of zero-knowledge proofs (the technology that underpins Zcash), the co-inventor of Zerocash protocol and ZK_STARKS, and the co-founder and CEO of StarkWare (BTCFi arc) 🥷. Timestamps: 00:00 – Intro 01:23 – Why is privacy important to you? 03:24 – Why is a lack of privacy holding blockchains back? 04:05 – Privacy is normal, so why isn’t it already normal in crypto? 06:10 – The dangers of CBDCs 09:00 – “If you have nothing to hide, you have nothing to fear” 12:53 – What are Zero Knowledge Proofs (ZKPs) and why are they important? 19:26 – What is Zcash and how does it work? 21:14 – Why is privacy suddenly trending? 23:15 – What happens if Bitcoin doesn’t address its lack of privacy? 28:03 – Can we stop a dystopian future?

Running parallel to the rise in interest has been the rise of Zcash 🛡️, now even with $ZEC treasury companies forming like Cypherpunk. In episode 2 of Not Dead Yet, Robert Baggs speaks with Eli Ben-Sasson | Starknet.io. Eli is a long-time researcher of zero-knowledge proofs (the technology that underpins Zcash), the co-inventor of Zerocash protocol and ZK_STARKS, and the co-founder and CEO of StarkWare (BTCFi arc) 🥷. Timestamps: 00:00 – Intro 01:23 – Why is privacy important to you? 03:24 – Why is a lack of privacy holding blockchains back? 04:05 – Privacy is normal, so why isn’t it already normal in crypto? 06:10 – The dangers of CBDCs 09:00 – “If you have nothing to hide, you have nothing to fear” 12:53 – What are Zero Knowledge Proofs (ZKPs) and why are they important? 19:26 – What is Zcash and how does it work? 21:14 – Why is privacy suddenly trending? 23:15 – What happens if Bitcoin doesn’t address its lack of privacy? 28:03 – Can we stop a dystopian future?

Did Epstein influence Bitcoin core development? Short answer: No. This is not how Bitcoin works. Here’s what happened: Epstein donated to MIT Media Lab…who in turn supported MIT Digital Currency Initiative…which in turn funded Bitcoin developers. These devs used to be funded by The Bitcoin Foundation (which I used to run as volunteer Executive Director) there are many devs and no dev or team had power or control over Bitcoin. Under MIT’s patronage the devs had the same deal they had with us at The Bitcoin Foundation: that they could work on the code and not have direction from the org. More importantly — how Bitcoin works is that *even if* a dev was compromised then the nodes and miners would still have to run that code to make it included in Bitcoin. So for example if I had somehow asked the devs paid by Bitcoin Foundation to “add 1000 coins for Bruce” 1) they wouldn’t have done this / it would have been counter to our agreement 2) no miners would run that code & no nodes would recognize it. It would be a laughing stock and completely rejected. Does this mean code dev is not an attack vector? No. It’s still a risk. Particularly with nation state style actors and very careful efforts to co-opt which are much more sophisticated than “give Bruce coins” or something. This is one reason I’m cautious of Bitcoin core funding - especially from actors who’ve had bad judgment in the past. I think we should be cautious of who does the dev and view it as an attack vector. Bitcoin code is transparent and has lots of eyes on it. So in this case especially there isn’t even a solid accusation, let alone evidence that MIT directed nefarious code changes. If that was an allegation the first question should be: well what code specifically did MIT direct and what proof is there and how was it harmful? I think claims around this would collapse. There’s obviously plenty to criticize about Epstein and MIT working with him — and when it comes to digital assets MIT’s work with Gensler and especially its work on CBDCs is much more suspect than the chance that malicious code was pushed through on Bitcoin. Be cautious but this is a nothing burger

Threadguy predicts this will be the first bull run in crypto history where Bitcoin doesn't participate "This is going to be the first bull run in the history of crypto where Bitcoin flat out does not participate. No role, no say, it will be minimal at best. It will be Bitcoin to $75k, Bitcoin to $80k, Bitcoin to $85k, and there will be mania on-chain." "My entire thesis is that the next cycle comes from new blood getting access to on chain through these apps. This new crowd doesn't even know what Bitcoin is. Anyone that joined because they saw Kimchi or Cented or Rasmr, they don't know what Bitcoin is. If there's a pocket of excitement and new blood in crypto, it will have nothing to do with Bitcoin, the same way Bitcoin had nothing to do with the disaster that on-chain became in 2025. You cannot have it both ways. The two have been separated for years."

Will McEvoy on why Cypherpunk went all-in on Zcash: "Cameron and Tyler have been following Zcash since 2016, when it launched. I joined up with them a little more than four years ago. We've been investing in AI, defense and longevity, and the through line is AI" "One of the core observations we made is that AI is extremely powerful from a surveillance perspective. We're in a structural decline in privacy, really since the advent of the internet. Phones, social media, comms apps, AI is just the latest step down" "Zcash was the first and largest production version of zero knowledge proofs, which Satoshi talks about early on, if something like ZK could be put into production, that would be a massive feature improvement to Bitcoin" "Privacy is a prerequisite to the Bill of Rights here in the United States. Privacy is core to being an American" "Bitcoin's great. It's what got me into the space. It's a massive technological revolution. But it's not private. That's why we launched Cypherpunk"

Tulip King puts shielded Zcash in the same “magic” category as his first experiences with Bitcoin and DeFi “You look at that shielded balance, and then you’re like, oh my god, I could send this anywhere, and nobody would know” “The only other time in crypto I’ve had that feeling was Bitcoin and DeFi” “Do the ZEC magic. Shield a little bit of Zcash” For Tulip King 🌷, using shielded ZEC creates the same kind of conviction he felt when first self-custodying Bitcoin and discovering DeFi. The product experience becomes the thesis: hold private money, transact privately, understand why it matters firsthand. His message is simple: try shielded $ZEC before forming an opinion on Zcash 🛡️.

"For every 10% Bitcoin goes down, your rate goes up 20 basis points. So even if Bitcoin goes to zero, your rate only increases by 2%. And it works the other way too" CJ Konstantinos, founder of Peoples Reserve, on how the self-repaying mortgage rate moves with Bitcoin "So, even if Bitcoin went to zero, it's just like a regular mortgage at that point, because you have no Bitcoin working for you anymore. We don't believe Bitcoin goes to zero, but if it did, that would be the consequence" "For every 10% Bitcoin goes up, we reduce your rate by 0.2%, up to a 33% LTV, a 300% collateral ratio. If your loan is $500,000 and you post $1.5 million of Bitcoin, or your original $500,000 grows into $1.5 million, we reduce your rate by 400 basis points. So if you're basic with an 8% starting rate but you over-collateralize, you get a 4% rate" "We believe over time Bitcoin will do what it was engineered to do and accrue value. Intraday volatility doesn't matter, it's a 30-day window. At the end of every month before your payment is due, we take a snapshot. So if Bitcoin flash crashes and bounces back, no change to your rate, it has to be a consistent drawdown over 30 days, and we reamortize the loan based on the collateral ratio at that time"

Grant Cardone explains why people still don't just buy Bitcoin "I think it goes back to the way the Bitcoin community explains it" "I've been looking at the asset for 13 years and I'd get turned off. I'd go into rooms and start hearing stories about how I have to have seed phrases and remember this and have this other thing, and I'm like, this is too complicated for me" "I wouldn't be in Bitcoin if somebody wouldn't have given it to me. I was given 115 pieces for a speaking gig. He literally had nothing else to give me, so I said okay, I'll take the Bitcoin, whatever that is"
