Visa is actively running a validator node on Tempo, an emerging blockchain network - to help advance secure, scalable blockchain infrastructure for payments.
Visa also recently announced its role as a Super Validator for the Canton Network, to help bring privacy-preserving onchain payments to regulated institutions.
Before diving into why validator nodes matter, let’s start with the basics: what they are, who can operate them, and why they’re essential to blockchain networks.
Tempo
Visa’s work on Tempo, a purpose-built blockchain for stablecoin payments, represents a deeper level of participation that further strengthens Visa’s expertise in operating blockchain infrastructure. Unlike many other networks where validator operations are outsourced by the validator entirely to third parties, Visa manages its Tempo validator node in-house, giving Visa end-to-end visibility into network performance and resilience.
Tempo is designed for high throughput and low latency - making stablecoin payments feel as familiar and frictionless as traditional transactions.
By running validators for public blockchains, Visa is helping shape how stablecoin networks operate at scale, how they integrate with existing settlement systems, and what it takes to meet the reliability and compliance standards of global payments.
Canton
After spending significant time operating a node on Tempo in testnet, before launching on Tempo mainnet, Visa recently announced it will also serve as a Super Validator on the Canton Network. Canton is a privacy-preserving blockchain built for regulated financial institutions.
As a Super Validator, Visa will help clients who choose to run and secure operations on the Canton Network, applying the same trusted and reliable standards it uses to operate critical payment systems today. Institutions can experiment with and scale stablecoin payments, settlement and treasury use cases without changing how they already manage risk, compliance and operations.
This role contributes payments expertise and operational reliability to a blockchain environment where regulated institutions can transact and collaborate with the privacy and controls they expect.
Why Visa is running a validator node
Visa’s decision to run a validator node is guided by a few consistent goals:
Strengthening critical blockchain infrastructure
Accelerating responsible adoption
