Microsoft Azure Becomes the Battleground for Enterprise Blockchain as R3 CEV Tests Ethereum With 11 Major Banks

TL;DR

• Microsoft positions Azure as the go-to cloud platform for enterprise blockchain deployments
• R3 CEV consortium of 11 major banks completes first Ethereum-based trial on Azure
• Santander estimates blockchain could save the banking industry $20 billion annually
• Ripple CEO Chris Larsen says Microsoft’s entry “adds credibility” to the blockchain sector
• IBM, Cisco, and Intel announce competing open-source blockchain initiative

The blockchain industry reached a pivotal moment on January 22, 2016, as Microsoft made its most aggressive play yet to become the infrastructure backbone of enterprise blockchain technology. The tech giant’s cloud computing platform, Azure, served as the testing ground for a landmark distributed ledger experiment coordinated by R3 CEV, a financial innovation firm that has been assembling a consortium of the world’s largest banks.

The experiment, completed just two days earlier on January 20, involved eleven major financial institutions — including UBS and Credit Suisse — running simulated trades on an Ethereum-based private ledger hosted entirely within Azure. For Microsoft, this was more than just a successful proof-of-concept; it was validation of a business strategy that could position Azure as the default infrastructure layer for financial institutions exploring distributed ledger technology.

Microsoft’s Blockchain-as-a-Service Vision

Marley Gray, who leads Microsoft’s blockchain initiative and serves as technology strategist for financial services at Azure, made the company’s ambitions clear. “We see a huge opportunity here,” Gray stated. “Enterprise-scale and enterprise-grade infrastructure is going to be vitally important for this financial infrastructure that will be woven using blockchain over these next few years.”

Microsoft’s approach centers on offering Blockchain-as-a-Service (BaaS) within Azure, allowing banks and corporations to deploy, manage, and experiment with blockchain networks without building their own infrastructure. The company has been striking partnerships with several blockchain startups, creating a marketplace of distributed ledger technologies that financial institutions can test and compare.

The strategy is straightforward but powerful: as banks and corporations rush to explore blockchain technology, they need reliable, scalable cloud infrastructure to host their networks. Microsoft wants Azure to be that infrastructure — the backbone upon which the next generation of financial technology is built.

The R3 CEV Experiment: Eleven Banks, One Ledger

The R3 CEV experiment marked one of the most significant milestones in enterprise blockchain adoption. Eleven of the world’s largest banks completed mock trades with one another via a private peer-to-peer distributed ledger, simulating the exchange of value represented by tokenized assets.

The choice of Ethereum as the underlying technology was notable. While Bitcoin’s blockchain remains the most battle-tested distributed ledger, Ethereum’s support for smart contracts — self-executing programs that can automate complex financial transactions — makes it particularly attractive to banks looking to modernize their operations.

The experiment demonstrated that private, permissioned blockchains could facilitate real-time settlement between financial institutions, potentially eliminating days of delays that plague current cross-border payment and settlement systems. With Bitcoin trading at approximately $382 and Ethereum at roughly $1.50 at the time, the crypto market itself was still in its early stages — yet the underlying technology was already attracting the attention of the world’s biggest banks.

A Competitive Landscape Emerges

Microsoft is not alone in recognizing the enterprise blockchain opportunity. IBM, Cisco, and Intel recently formed an open-source project to develop blockchain software for corporate use, creating a competing ecosystem that could challenge Microsoft’s Azure-centric approach.

The involvement of these tech giants signals a broader shift in how the industry views blockchain technology. What began as the foundation for a niche digital currency has evolved into a potentially transformative infrastructure technology for global finance. Santander, one of the banks exploring blockchain applications, has estimated that the technology could save the banking industry $20 billion annually in back-office and infrastructure costs.

Chris Larsen, CEO of Ripple — a company whose cryptographic ledger technology is being tested by partners including Accenture — praised Microsoft’s entry into the space. Since the previous month, Microsoft has been running one of the software nodes that power Ripple’s ledger technology. “Microsoft adds credibility as to where the industry is going,” Larsen said.

Challenges and Skepticism

Despite the enthusiasm, significant challenges remain. Blockchains are not yet being put to work in any meaningful commercial way, and the mismatch between banks’ ambitious pronouncements and the embryonic state of actual blockchain deployments has led to growing criticism that the technology is overhyped.

Chris Finan, CEO of Manifold Technology — which is testing its blockchain software with the Royal Bank of Canada and is also a Microsoft partner — acknowledged the gap between promise and reality. “We should be comparing ourselves with other infrastructure companies like the Oracles and SAPs of the world,” Finan noted. “We need to prove why this kind of infrastructure is more efficient.”

Why This Matters

Microsoft’s blockchain push represents a critical inflection point for the technology’s journey from niche experiment to mainstream enterprise tool. When a company of Microsoft’s stature and resources commits to blockchain infrastructure, it sends a powerful signal to both the financial industry and regulators that distributed ledger technology has moved beyond the proof-of-concept phase.

The R3 CEV experiment on Azure demonstrates that the technology works in a multi-institutional setting — even if only with simulated trades. The real test will come when these systems are deployed in production environments handling actual financial transactions. For now, Microsoft has positioned itself at the center of what could become a fundamental reshaping of global financial infrastructure.
