Visa: Should Blockchains Have Embedded Privacy?

Serving as the “first major global payments company” to be named a Super Validator, Visa is joining 40 other Super Validators on Canton. 

The role entails giving Visa voting power to decide critical infrastructure, facilitating the adoption of blockchain technology at scale. The role is reserved for “highly trusted” institutions, further cementing its stablecoin ambitions. 

The Canton Network, a public network built for financial institutions, meets a market need for private transactions on shared infrastructure. 

In its capacity as a Super Validator, Visa will apply trusted and reliable standards to clients that select the Canton Network for operations. 

This allows institutions to experiment in the scaling of stablecoin operations, without compromising risk and compliance. 

Canton supports wide adoption in capital markets, acting as a powerhouse for the issuance and trading of tokenised financial assets. 

Visa’s entrance will facilitate the bridge between capital markets and payments, bringing onchain payments directly into Canton’s ecosystem. 

Rubail Birwadker, Global Head of Growth Products and Strategic Partnerships at Visa notes: “Many banks see the lack of privacy as a dealbreaker for moving meaningful activity onchain.

“By operating as a Super Validator on Canton Network, we’re bringing Visa-grade trust, governance and operational rigor that define Visa’s global network to privacy‑preserving blockchain infrastructure, so regulated FIs can bring payments onchain without having to rethink how they operate.”

Is the Canton Network really built for privacy? 

Canton has privacy “built in from the beginning” to allow financial institutions transparency that is associated with blockchain without compromising privacy expectations that financial institutions are expected to operate under. 

Eric Saraniecki, Head of Network Strategy for Digital Asset, co-creator of Canton says: “Canton was built to meet the requirements of regulated finance from day one. Visa’s participation as a Super Validator reinforces that this technology has matured beyond experimentation and into production‑ready infrastructure. Bringing payments onchain, alongside assets, unlocks the next phase of financial markets, where transactions can move with the speed of blockchain while remaining private, secure, and compliant.”

The network is designed with real-world use cases in mind, as the benefits of blockchain can’t contend with sensitive issues such as public payroll and price discovery. 

The combination of privacy in addition to the connection of applications on the network positions it as a strong leader in privacy in the blockchain landscape. 

Visa and its digital assets 

Building on its previous work with digital assets, Visa’s involvement on both a governance and payments level will ensure that the stablecoin strategy is growing. 

The business’s prior commitments to digital assets include stablecoin settlement, which it claims has a run rate of US$4.6bn, globally. 

Additionally, it released stablecoin-linked cards connecting over 130 programmes spanning 50 countries. 

Its Stablecoin Advisory Practice informs clients that include fintechs and financial institutions about stablecoin strategy and onchain capabilities. 

Visa Consulting & Analytics, who run the advisory, can aid clients to assess how their objectives align with initiatives such as participation in the Canton Network. 

It will remain “chain-agnostic” across networks that are aligned with its institutional payments-first approach.
