Microsoft has been a major player in the development of blockchain technology. The company has been involved with Ethereum since its early days and has even developed its own blockchain-based platform, called Azure Blockchain Services.

However, Microsoft does not own Ethereum. The Ethereum Foundation, a non-profit organization that supports the development of the Ethereum protocol, is the primary steward of the Ethereum network.

While Microsoft is a major contributor to the Ethereum ecosystem, it does not have control over the network in the same way that it does with other platforms like Windows or Azure.

Microsoft’s involvement with Ethereum is largely due to its interest in blockchain technology and its potential applications. The company has been working on several blockchain-based projects, including a decentralized ID system called Identity Overlay Network (ION) and a digital rights management platform called Content Guard.

Microsoft’s interest in Ethereum is also evident in its recent partnership with ConsenSys, a leading Ethereum development studio. The two companies are working together to develop tools and services that will make it easier for enterprises to build and deploy decentralized applications on the Ethereum network.

While Microsoft does not currently own Ethereum, it is clear that the company is heavily invested in the success of the platform. With its deep understanding of blockchain technology and strong partnerships within the Ethereum community, Microsoft is well positioned to play a major role in shaping the future of this promising technology.
