Balaji Srinivasan has distilled 15 years of crypto experimentation all the way down to a stark declare: after Bitcoin, solely two core protocol breakthroughs actually matter—Ethereum for programmability and Zcash for privateness.
In a wide-ranging look on Mert Mumtaz’s “Speed up with Mert” podcast, Srinivasan argued that the trade has already accomplished the “programmability period” and is now getting into a decisive section the place privateness and zero-knowledge cryptography develop into central to crypto’s mission. “The 2 main improvements on Bitcoin have been programmability within the type of Ethereum and privateness within the type of Zcash,” he mentioned.
From Bitcoin To Programmability To Zcash
Srinivasan breaks crypto’s historical past into three arcs. First, Bitcoin merely needed to show that non-sovereign, cryptographic cash may work in any respect. Then, Ethereum generalized that right into a programmable platform with good contracts, stablecoins, NFTs, DEXs and on-chain capital markets.
By now, he argued, that second section is successfully validated. “We now have scalable on-chain good contracts that may assist [a] massive variety of customers, massive numbers of transactions with finality. There’s a number of good chains. It really works. It runs 24/7,” he mentioned, noting that crypto is already functioning in creating markets: “In Bolivia, they quote costs in Tether. In Nigeria, they save in Bitcoin. These items is not principle. It’s truly there.”
The following section, he says, is privateness by design. “Now the following eight years… privateness,” Srinivasan mentioned. “Taking all the pieces we simply did and encrypting it utilizing ZK.” That features ZK-based KYC (“ZKYC”), privacy-preserving DEXs, and good contracts that reveal solely the minimal needed data. He pointed to trade work exhibiting how conventional KYC may very well be replicated with zero-knowledge proofs: “If you happen to nail ZK then you may substitute all the [compliance] system.”
That is the place Zcash issues: not as a advertising and marketing model, however as the primary mainstream proof that superior zero-knowledge privateness will be embedded on the protocol degree. Ethereum represents programmability; Zcash represents privateness. In Srinivasan’s framing, the longer term is about merging these concepts—Ethereum-style expressivity with Zcash-style cryptographic concealment—throughout L1s, rollups and application-specific programs.

Srinivasan pushed again exhausting on the concept crypto is now primarily a speculative or business enviornment. “Crypto isn’t simply in regards to the business half,” he mentioned. “It’s in regards to the ideological half. It’s about the truth that the banks have failed. It’s in regards to the reality the political system has failed. It’s about the truth that we want an exit. It’s about the truth that we want self-sovereignty. And the lacking a part of that’s privateness.”
He in contrast this to the way in which Christmas is usually defended by non secular believers as greater than purchasing and Santa. “Keep in mind the rationale for the season” turns into, in his telling, a reminder that crypto’s “season” is about exit and self-sovereignty, not simply yield, DeFi and token costs. Privateness, he argued, is what reconnects fashionable “business crypto” to these authentic cypherpunk and anti-censorship roots.
Notably, Srinivasan is a long-time advocate for ZK primarily based applied sciences. In November 2024, he wrote through X: “Sure, Zcash is nice and it’s already match for goal. One can proceed utilizing it for personal transactions. However ZK is to encryption what the transformer is to AI. It generalizes many particular case hacks into a brand new compute paradigm. We’ll get a ZK economic system. So we do need a chain with ZK primitives along with a easy Zcash-like chain.”
At press time, ZCash traded at $501.59.
