On November 9, 2015, Microsoft made a bold bet on blockchain technology that would prove prescient in the years to come. The tech giant, in partnership with blockchain startup ConsenSys, launched Ethereum Blockchain-as-a-Service (EBaaS) on its Azure cloud platform — marking the first time a major technology corporation offered enterprise-grade blockchain infrastructure to the public. The announcement sent ripples through both the traditional tech world and the cryptocurrency community, signaling that blockchain had moved far beyond its origins as the backbone of Bitcoin.
TL;DR
- Microsoft partnered with ConsenSys to launch Ethereum Blockchain-as-a-Service on Azure
- Enterprise clients could create blockchain-based smart contracts using simple templates
- Companies could deploy their own Ethereum-based currency in just 20 minutes
- The platform updated values every 15 seconds — 40 times faster than Bitcoin
- BTC was trading at approximately $311 at the time of the announcement
A Strategic Pivot Under Satya Nadella
Under CEO Satya Nadella, Microsoft had been aggressively expanding its cloud services portfolio, moving well beyond its traditional reliance on Windows and Office. The Azure platform was becoming a serious competitor to Amazon Web Services, and the addition of blockchain services represented a forward-thinking move to attract enterprise developers and financial institutions.
Marley Gray, Director of Business Development and Strategy for Cloud and Enterprise at Microsoft, spearheaded the initiative. The partnership with ConsenSys — founded by Joseph Lubin, one of Ethereum’s co-founders — gave Microsoft direct access to the most advanced smart contract platform in existence. At the time, Ethereum was still in its early stages, having launched its frontier network just months earlier in July 2015.
What Enterprise Blockchain-as-a-Service Offered
The EBaaS offering on Azure was designed to lower the barrier to entry for businesses interested in experimenting with blockchain technology. Through simple templates, companies could spin up blockchain-based smart contracts without needing deep expertise in distributed systems or cryptography. Microsoft emphasized that Bitcoin-style applications were “just scratching the surface” of what was possible when combining cryptographic security with blockchain’s reliability.
One of the most compelling features was the ability for organizations to create their own Ethereum-based digital currency in approximately 20 minutes. These private currencies could update their values every 15 seconds — roughly 40 times faster than Bitcoin’s 10-minute block time. The platform leveraged peer-to-peer networks and consensus algorithms to secure transactions, mirroring Bitcoin’s fundamental architecture while offering enterprise-grade customization.
Banks Take Notice
The timing of the announcement was strategic. Throughout 2015, major financial institutions had begun expressing serious interest in blockchain technology. Banks saw potential in using distributed ledgers for settlement, clearing, and trade finance — areas where legacy systems were slow and expensive. Microsoft’s Azure offering gave these institutions a sandbox environment to experiment with the technology without committing to the public Ethereum network.
The technology could also secure and verify the exchange of any type of data, making it relevant to industries well beyond finance, including supply chain management, healthcare records, and digital identity verification.
The Broader Crypto Market Context
The launch came during a turbulent period for cryptocurrency prices. Bitcoin was trading at approximately $311, having suffered a sharp 28% decline over the preceding seven days. Ethereum, still in its infancy, was priced at just $0.79 with a market capitalization of roughly $59 million — a far cry from the hundreds of billions it would eventually command. Litecoin traded at $2.97, and XRP sat at $0.004. The total cryptocurrency market capitalization hovered around $4.6 billion, with Bitcoin dominating at over 95% of the total.
Despite the market downturn, the Microsoft-Azure partnership represented a critical validation of blockchain technology by the mainstream tech establishment. It demonstrated that the underlying innovation extended well beyond speculative trading, offering real utility for enterprise applications.
Why This Matters
Microsoft’s Ethereum Blockchain-as-a-Service launch on Azure was a watershed moment for enterprise blockchain adoption. It predates the Enterprise Ethereum Alliance (EEA) formation by over a year and laid the groundwork for the institutional embrace of distributed ledger technology that would accelerate throughout 2016 and 2017. The partnership with ConsenSys also validated Ethereum’s potential as a platform for more than just a cryptocurrency — it was a programmable blockchain capable of supporting complex business logic through smart contracts. For the cryptocurrency industry, Microsoft’s endorsement provided credibility at a time when Bitcoin’s price was still reeling from the post-2014 bear market, and the broader public remained skeptical about digital currencies.
