Backend Jobs at Blockchains

OUR VISION

In the new and exciting world of the decentralized internet, otherwise known as Web3, it is an individual’s fundamental right to own and control their digital identity. To ensure that the individual is paramount in Web3, we are developing a suite of applications to enable everyone to safely engage, take part, and transact in the emerging, decentralized world of the internet. Our platform centers on Web3 Identity and leverages that identity to provide individuals with secure digital asset storage and recovery, access to decentralized finance, the ability to prove ownership of their creations, and gateways to digital interactions and experiences – all to empower and benefit every Web3 user.

We believe that the decentralized nature of Web3 creates an opportunity for everyone to challenge the digital status quo—to own and control their identity, data, finances, creations, and future. This is the chance to get it right – to rally a movement of individuals so Web3 belongs to everyone, not to trillion-dollar companies. To fulfill this vision, we are seeking dynamic people who want to join us in leading the way to this new world.
