ℹ️ o1js is an evolution of SnarkyJS which saw 49 updated versions over two years of development with 43,141 downloads.
This name change to o1js 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:
To update zkApp-cli, run the following command:
npm i -g zkapp-cli@latest
To remove the now-deprecated SnarkyJS package and install o1js, run the following command:
npm remove snarkyjs && npm install o1js
For existing zkApps, make sure to update your imports from snarkyjs to o1js
No need to redeploy, you are good to go!
o1js 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.
