Founded in July 2021, TBD is one of Block's four business units, alongside Square, Cash App, and Tidal. At TBD, we believe in a decentralized future that returns ownership and control over your finances, data, and identity. Guided by this vision, TBD is building an open source platform and developer infrastructure that enables everyone to access and participate in the global economy.

TBD is inviting the world to join us in building and adopting open and decentralized technologies that solve real problems for real people — from next generation infrastructure that lowers the cost of global payments and enables frictionless commerce, to decentralized identity technologies that enable anyone to access and participate in the global economy.
