The crypto neighborhood on X has been dominated by distinguished figures advocating for the adoption of Zcash as privateness turns into more and more threatened by governments and regulators.
Whereas the Winklevoss twins, Naval Ravikant, and Balaji Srinivasan again the adoption of Zcash (ZEC), its success might spur the Bitcoin ecosystem to push for extra privateness options by revisiting the reactivation of OP_CAT, in accordance to Eli Ben-Sasson, founding father of StarkWare and a famend mathematician who helped pioneer zero-knowledge proofs.
Zcash was impressed by Bitcoin
In 2014, Ben-Sasson and his co-authors printed “Zerocash: Decentralized Nameless Funds from Bitcoin.”
The white paper was the end result of six years of theoretical work. From 2008, Ben-Sasson and his collaborators had been working on general-purpose zero-knowledge proof know-how. Whereas they didn’t have a use case, they knew the know-how was extremely highly effective.
Zcash has been trending on Crypto Twitter for months.
Not many know the backstory behind the most important cryptocurrency within the privateness area.
We’re chatting to @EliBenSasson concerning the historical past of @Zcash and the ZK tech behind it.

“We knew zero-knowledge proofs clear up two issues: scalability and privateness. They provide integrity. They principally can persuade you that the appropriate factor has been accomplished, even while you’re not watching and even while you don’t truly see all the small print,” Ben-Sasson advised Cointelegraph’s Chain Response liveshow on X.
Every part modified in 2013 when Ben-Sasson gave a chat on ZK at one of many earliest editions of the Bitcoin convention.
“I received off the rostrum and a bunch of very influential Bitcoin OGs, like Greg Maxwell and Mike Hearn, got here up and stated, ‘OK, the place’s the tech? When can we use the code?’ And I requested them, ‘Why do you want it?’”

These early Bitcoin (BTC) builders and advocates outlined a number of ways in which Bitcoin may benefit from the brand new methodology. All of the sudden, ZK-proofs had discovered their killer use case.
“So we labored very diligently on publishing one thing that shows how this know-how can clear up one of the vital necessary issues of blockchains, which is the truth that while you’re doing a Bitcoin transaction, everybody can see the quantity, can just about determine who paid whom and the way a lot.”
This transparency, whereas by design, means that there’s an inescapable aspect of transparency when utilizing Bitcoin. ZK-proofs provide an answer, however Bitcoin’s code doesn’t enable for his or her inclusion due to a call made by Satoshi Nakamoto a few years in the past.
Why OP_CAT holds the important thing to privateness on Bitcoin
Ben-Sasson stated that Bitcoin can nonetheless have native privateness and infinite scalability if builders can agree to reinstate OP_CAT, a Satoshi-era OP_Code that Bitcoin’s creator disabled in 2010.
He additionally famous that Zcash’s resurgence in 2025 might function a possible catalyst for Bitcoin’s push for privateness.
There have been whispers of Bitcoin hodlers swapping BTC for Zcash 🤔🔏
Why? As a result of some Bitcoiners need to have the opportunity to transact with extra privateness.
BUT Bitcoin can nonetheless have NATIVE privateness and scale. @EliBenSasson explains how ZK-proofs and OP_CAT maintain the important thing 🗝️👇

“I hope that one consequence of this could be that the Bitcoin neighborhood turns into extra open to issues like OP_CAT and OP_STARK in order that it could have post-quantum safety, privateness, scale and programmability for this lovely arduous asset that’s Bitcoin,” Ben-Sasson stated.
“The know-how is prepared. All you want is a delicate fork that provides 9 traces of code, which Satoshi truly launched. It’s known as OP_CAT. It’s very, very simple. If there’s a will, there’s a manner. On this case, it’s a quite simple manner to give all of that goodness to Bitcoin itself.”

Outstanding Bitcoiners on social media have largely stayed away from the Zcash narrative, and there has but to be any actual dialog about methods to enhance privateness when utilizing Bitcoin for funds.
Cointelegraph additionally spoke solely to Gemini co-founders Cameron and Tyler Winklevoss at Bitcoin Amsterdam, who defined their perception in Zcash’s potential to complement Bitcoin.
The twins made headlines after saying the launch of Cypherpunk Applied sciences, a ZEC-based treasury firm, following their acquisition and rebranding of Nasdaq-listed Leap Therapeutics in November.
