The crypto group on X has been dominated by outstanding 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 line with 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 fruits of six years of theoretical work. From 2008, Ben-Sasson and his collaborators had been engaged on general-purpose zero-knowledge proof expertise. Whereas they didn’t have a use case, they knew the expertise 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 mainly can persuade you that the precise factor has been achieved, even if you’re not watching and even if you don’t really see all the main points,” Ben-Sasson informed Cointelegraph’s Chain Response liveshow on X.
All the things 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. Immediately, ZK-proofs had discovered their killer use case.
“So we labored very diligently on publishing one thing that shows how this expertise can clear up one of the crucial essential issues of blockchains, which is the truth that if you’re doing a Bitcoin transaction, everybody can see the quantity, can just about work out 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 supply an answer, however Bitcoin’s code doesn’t enable for his or her inclusion because of a choice 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 conform 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 ability 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 is able to be that the Bitcoin group 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 onerous asset that’s Bitcoin,” Ben-Sasson stated.
“The expertise is prepared. All you want is a delicate fork that provides 9 traces of code, which Satoshi really launched. It’s referred to as OP_CAT. It’s very, very straightforward. If there’s a will, there’s a approach. On this case, it’s a quite simple option to give all of that goodness to Bitcoin itself.”

Distinguished 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 completely to Gemini co-founders Cameron and Tyler Winklevoss at Bitcoin Amsterdam, who defined their perception in Zcash’s potential to enrich Bitcoin.
The twins made headlines after asserting the launch of Cypherpunk Applied sciences, a ZEC-based treasury firm, following their acquisition and rebranding of Nasdaq-listed Leap Therapeutics in November.
