Global payments giant Visa has made a significant leap in the payments industry by deploying its core infrastructure directly onto a blockchain for the first time. The company has taken on the role of “anchor validator” on the Stripe-backed Tempo blockchain—a key position that directly supports the network’s security and transparency. The move comes after nearly six months of technical integration work, marking a new chapter in Visa’s digital payments strategy.
Visa moves blockchain operations in-house
Following a technical partnership with Tempo, Visa announced that it has begun managing a validator node on the blockchain, entirely running on its own infrastructure. This transition was achieved through close collaboration between Visa’s internal teams and Tempo’s engineers. Having previously made strides in blockchain and stablecoin initiatives, Visa is now embedding its core payment infrastructure directly onto the blockchain via this partnership with Tempo.
Cuy Sheffield, head of Visa’s crypto division, emphasized that the company has been working on stablecoin technologies for over seven years. Looking ahead, Sheffield underscored the company’s focus on supporting novel payment flows, including AI-driven machine-to-machine payments.
Sheffield explained their keen interest in Tempo’s innovations and ecosystem, highlighting that the Visa CLI wallet operates on the MPP protocol—enabling AI-powered software to make Visa card payments autonomously.
Tempo, a blockchain platform backed by prominent crypto investment firm Paradigm, recently introduced its Machine Payments Protocol (MPP). Launched last month, the MPP makes it possible for AI and software agents to carry out payments for services independently. Visa’s pivotal role in Tempo’s technical infrastructure further deepens the collaboration between the two companies as they explore frontiers in autonomous payments.
A pragmatic approach to blockchain integration
Visa is now considering plans to run similar validator nodes on other blockchain networks following the Tempo integration. The company is also eyeing a “Super Validator” role on the Canton Network. By leveraging blockchain-based networks, Visa aims to gain a competitive edge in speed and efficiency while evaluating a wider range of next-generation payment infrastructures.
Stripe’s entrepreneurial push into stablecoins stood out earlier this year with its $1.1 billion acquisition of Bridge, a major player in the sector. Similarly, Mastercard expanded into blockchain by acquiring BVNK for $1.8 billion this year. These moves signal a strategic industry-wide shift by established payment giants towards stablecoins and blockchain technologies.
Cuy Sheffield pointed out that decentralization alone does not solve core challenges; instead, the true priority is to build a payment infrastructure that is programmable, fast, and demonstrably better than existing systems.
Uncertainty remains around Visa’s next stablecoin moves
Responding to questions on whether Visa plans to launch its own stablecoin, Sheffield noted that regulatory ambiguities still persist. He added that the company is in ongoing talks with the U.S. Office of the Comptroller of the Currency (OCC). Visa remains committed to working closely with its partners and networks in any potential new initiatives, moving cautiously in this rapidly evolving environment.
Experts say Visa’s deep involvement at the infrastructure level of the blockchain signals an important shift for the future of payment systems. By proceeding cautiously both on the technical and regulatory fronts, Visa sets a measured example for the payments industry as a whole.
