What do I need to use Ujo?

In order to get started you need a computer or laptop with the most up-to-date version of Chrome, Firefox, or Brave browser. Additionally you'll need MetaMask, a digital wallet service, loaded with ether. To acquire ether, please see the section 'How do I get Ether, the digital currency?' below.


The Ujo platform uses blockchain technology to create a transparent and decentralized database of rights and rights owners, automating royalty payments using smart contracts and cryptocurrency.

Decentralized File Storage

Decentralized and distributed file storage systems enable redundant data that is fault-tolerant, resilient, censorship-resistant, and self-sustaining due to built-in incentive systems. Technologies such as the InterPlanetary File System (IPFS) and Swarm use peer-to-peer networks to transmit information eliminating the need for the fragile and siloed databases of centralized service providers today. Data is content-addressable meaning it can be retrieved using a cryptographic hash of the data itself rather than the location of a specific entity's server, lending to a fast and future-proof metadata and media file storage.

Metadata - Constellate

An open, global database of rights-holders and their works allows service providers to more easily license the works for myriad use cases. In order to do so, a modern, machine-readable, content-addressed metadata standard is required. Constellate incorporates the collaborative COALA IP specification, extended to interface with Ethereum ontologies (EthOn).

Licensing + Payments - Ethereum

Ethereum is utilized to build out flexible & modular licensing systems. Enabling automated payments to rights holders based on licenses they design themselves in our friendly and easy-to-use interface. It can be extended to incorporate a wide range of additional functionality: programmatic contracts, variable pricing, payment routing.

Persistent Identity - uPort

Artists spend years putting effort into their creative work, and fans with curating their collections. With the digital age, a service can shut down and take all of that away. Ethereum, the same system that allows for flexible licensing, also allows us to ensure that artists don't lose control of their identities, their fans, and the work they have created.
