ℹ️ o1js is an evolution of SnarkyJS which saw: 49 updated versions over 2 years of development with 43,141 downloads
This name change reflects the evolution of our vision for the premiere toolkit used by developers to build zero knowledge-enabled applications, while paying homage to our technology's recursive proof generation capabilities.
Your favorite functionality stays the same and transitioning to o1js is a quick and easy process:
npm i -g zkapp-cli@latestnpm remove snarkyjs && npm install o1jssnarkyjs to o1jso1js helps developers build apps powered by zero-knowledge (zk) cryptography.
The easiest way to write zk programs is using o1js.
o1js is a TypeScript library for zk-SNARKs and zkApps. You can use o1js to write zk smart contracts based on zero-knowledge proofs for the Mina Protocol.
o1js is automatically included when you create a project using the Mina zkApp CLI.
To learn more about developing zkApps, see the zkApp Developers docs.
For guided steps building and using zkApps, see the zkApp Developers Tutorials.
To meet other developers building zkApps with o1js, participate in the #zkapps-developers channel on Mina Protocol Discord.
For a list of changes between versions, see the CHANGELOG.
To stay up to date with o1js, see the O(1) Labs Blog.
