Payments giant Square released a white paper on Friday detailing a new decentralized protocol for exchanging digital and other assets known as tbDEX.

• “The tbDEX protocol facilitates decentralized networks of exchange between assets by providing a framework for establishing social trust, utilizing decentralized identity (DID) and verifiable credentials (VCs) to establish the provenance of identity in the real world,” the company wrote in the paper’s abstract.

• In a post introducing the protocol, a TBD developer wrote that “the tbDEX protocol aims to create ubiquitous and accessible on-ramps and off-ramps that allow the average individual to benefit from crypto innovation.”

• TBD has published the white paper in GitHub so that the community can contribute.

• Square CEO Jack Dorsey, who’s also the CEO of Twitter, announced the company’s plan to create an open developer platform for a decentralized bitcoin exchange back in August. He noted that TBD, Square’s new division focused on developing non-custodial and decentralized financial services, would be building the exchange.

• Mike Brock, who heads strategic development at Square, is leading the new project. Brock has previously tweeted that “this is the problem we’re going to solve: make it easy to fund a non-custodial wallet anywhere in the world through a platform to build on- and off-ramps into bitcoin. You can think about this as a decentralize[d] exchange for fiat.”
