Aleph Zero was established in early 2018 with a vision to provide the first truly scalable, decentralized, and open-sourced DLT ecosystem. After 6 years on the market, we’re confident that we’re going in the right direction.

We're building a new blockchain platform using novel protocols published in scientific papers. We work on problems in the fields of cryptography, concurrent algorithms, and distributed systems. We use a mixture of technologies, with Rust for our backend systems and TypeScript for our frontends. We have a flat hierarchy and we make collective decisions where everyone is equally heard and listened to.
