Visa Deepens Blockchain Involvement With Tempo Network Validator

“The launch underscores Visa’s commitment to running critical blockchain operations in-house and strengthening the foundations of onchain payment innovation,” the company said in a Tuesday (April 14) news release.

Visa’s move is part of a larger expansion of Tempo, a blockchain designed for agentic commerce and real-time payments. In addition to Visa, Stripe and Standard Chartered’s Zodia Custody have also become external validators, the release said.

“We’ve spent years building our expertise in blockchain, and now we’re expanding that work by running critical blockchain infrastructure ourselves,” said Cuy Sheffield, Visa’s head of crypto.

“By operating a validator on Tempo, we’re extending Visa’s commitment to reliability, security, and trust into blockchain networks – supporting the development of stablecoin payment systems that meet the high operating standards our clients and partners expect.”

According to the release, Visa’s validator node was configured and managed in-house, after six months of joint work with Tempo’s engineers to integrate Visa’s secure infrastructure with the Tempo network.

“This approach places Visa at the core of transaction validation and supports the overall security of the network,” the company said. “By operating as an anchor validator during this initial phase, Visa is helping ensure Tempo operates with the reliability, resilience, and performance required for emerging payment use cases.”

As PYMNTS wrote earlier this month, Visa is part of a larger group of Fortune 500 companies running their own validator notes on blockchain networks.

“The analogy most often used is that validators are the ‘servers’ of blockchain networks,” that report said.

“That framing may be directionally helpful but is ultimately incomplete. Unlike traditional servers, validators are not owned by a single entity; they operate within decentralized systems, enforce protocol rules and are economically incentivized. In doing so, they can shape transaction throughput, fee dynamics and network security.”

By running validators, companies insert themselves into the transaction validation process. They get insights into network performance, influence over governance decisions in some protocols, and, crucially, access to new revenue streams. In proof-of-stake systems, validators can be rewarded for securing the network, usually in the form of newly issued tokens and transaction fees.

“For CFOs, this represents a departure from the traditional cost-only view of infrastructure. Validators can be profit centers, albeit with volatility tied to token prices and network activity,” PYMNTS wrote. “The decision to operate one is therefore not just technical; it is an allocation of capital with expected returns, risks and operational overhead.”
