Distributed file storage startup Storj Labs is the latest blockchain service provider to join Microsoft’s Blockchain-as-a-service (BaaS) offering.

In a blog post today, Storj revealed the news while providing an overview of how it creates a decentralized market for unused disk space, enabling it to be bought and sold for its native cryptocurrency SJCX.

The announcement follows the March news that Microsoft had added Augur, BitShares, Lisk and Syscoin to its development testbed.

Microsoft has previously indicated that it does not intend to limit the number of blockchain providers accepted into the testing version of its BaaS service.

A more formal certified offering would likely be released this spring, at which time technology providers involved are expected to pass a more stringent review, the company has said.

Founded in 2014, Storj raised some $500,000 worth of bitcoin in a public crowdsale that year.
