Buterin’s Bold Vision: Zero-Knowledge Proofs Could Revolutionize Social Algorithms
Ethereum co-founder Vitalik Buterin just dropped a bombshell proposal—what if we used zero-knowledge proofs to rebuild social media from the ground up?
Forget 'trust us' with your data. The pitch is simple: let users prove things about themselves—their reputation, their credentials, their membership—without revealing a single private detail. Algorithms get the verification they crave; you keep your life locked down.

Imagine a recommendation engine that doesn't need to hoover up your location, contacts, and browsing history. Zero-knowledge proofs could let it confirm you're in a relevant demographic or have certain interests, all while your actual identity stays anonymous. It turns the current surveillance-for-engagement model on its head.
Bypassing the Big Tech Middleman
This isn't just a tweak—it's a potential architectural overhaul. Social platforms currently act as centralized data custodians, a massive honeypot for hackers and regulators alike. Buterin's concept suggests a path where the platform never holds the raw data in the first place. It cuts out the liability—and the creepy ads that fund those lavish campus perks.
A Cynic's Corner
Of course, the finance world will immediately try to tokenize it. Get ready for the 'ZK-Social-Fi' narrative to pump some obscure coin 300% before anyone even builds a working prototype. Because why solve human connection when you can just create a new speculative asset class?
The idea is provocative, technically audacious, and perfectly timed. As public trust in big tech erodes daily, Buterin is sketching a blueprint for a social web that might actually deserve the word 'social.' Now, who's going to build it?
Zero-knowledge proofs as a tool for algorithm accountability
Under Buterin’s proposal, platforms WOULD produce cryptographic proofs that algorithmic results align with preset goals. He proposed that the creation time of content and the timestamp of engagement could be recorded using blockchain to minimize the risk of censorship, suppression, or retroactive manipulation of content.
I would go further. ZK-prove every decision made by the algorithm (ideally have content and likes/RTss timestamped onchain so the server can't censor or lie about time), and commit to publishing the full algorithm code with a 1-2 year delay.

To alleviate concerns about intellectual property and system security, Buterin suggested that the full algorithm code should not be released immediately, but rather after a delay of one to two years.
The discussion gained attention following Buterin’s comments on what he referred to as coordinated attacks against Europe on social platforms in public. In follow-up exchanges, he warned that allowing a platform to become a symbol of free speech worldwide, yet opening it up to large-scale, coordinated harassment, could result in a long-term backlash against open discourse.
The larger debate also brought into focus concerns over automated amplification. Participants noted the potential for AI-driven bot networks to generate large volumes of synthetic engagement, suggesting that “more speech” is often insufficient to counter harmful narratives.
Combining ZK proofs with other cryptographic systems
In addition to social algorithms, Buterin has proposed placing zero-knowledge proofs on top of other cryptographic algorithms, such as multi-party computation (MPC), fully homomorphic encryption (FHE) and trusted execution environments (TEE).
Among such applications, he has singled out voting systems, where coercion and privacy resistance are paramount to the safety of participants in blockchain-based governance. To ensure the security of the people who make the decisions, blockchain communities have already studied the ZK-based voting models, and they are becoming more and more popular among people who are interested in privacy-sensitive systems. This layered architecture is expected to reduce the risks that would be experienced if the cryptographic tools were implemented in isolation.
Adoption, technical progress, and ongoing risks
There has been a huge adoption of zero-knowledge technology. As of 2025, the total value locked in protocols built on ZK was more than $28 billion. ZK rollups have also been used by major institutions, like Goldman Sachs, Sony, and Deutsche Bank to secure transactions, verify NFTs, and compliance-related operations as well.
Over $ 100 billion worth of transactions using stablecoins is now being carried out on ZK rollups, with a huge portion represented by the stablecoins USDT and USDC.
Technically, the set of protocols written by Buterin, known as the GKR protocol codes, has made the verification of complex computations more efficient, allowing full nodes to be run by ordinary users using standard hardware.
