About us

cheqd is a ground-breaking startup in the space of self-sovereign identity (SSI). SSI is a new paradigm for exchanging trusted digital data related to people, companies, and things in a much more secure and privacy-preserving fashion that puts people in control of their data.

Our mission is to make digital identity more accessible, inclusive, and commercially sustainable. Our core product is a blockchain network that makes exchanging and paying for trusted data easy, inclusive, and secure. We built this core on blockchain technology, as we believe no single company should be in control of such critical Web infrastructure.

Our vision is that this new form of digital identity applies beyond just the financial industry and will be transformative for almost every industry sector imaginable. Through our network, anyone can verify identities quickly and securely with the ability for organisations to check the data to be compensated for their work.

Our differentiator is that our software rewards all parties involved in a trusted data ecosystem: from the individuals the data belongs to, the reputable organisations that issue and receive digital credentials, and the blockchain node operators on cheqd's network that facilitate value exchange in a decentralised and democratic manner.

Whilst commercial viability is key, this can't be to the detriment of inclusion, privacy and sustainability, which we will uphold as principles. Read more about our vision for new business models for digital identity .

We have published content through our blog , YouTube channel , X/Twitter , and Telegram . We are eager to engage with people who are serious about the space and, expect someone to have dedicated some time to understand what we're about when applying.
