Hello! I would like to nominate 0xPARC, a community organization that has developed educational resources, tools, and implementations of ZK cryptography including:
- https://learn.0xparc.org/
- https://zkrepl.dev/
- GitHub - 0xPARC/circom-ecdsa: Big integer arithmetic and secp256k1 ECC operations in circom
Additionally, 0xPARC has supported the developers of projects like Dark Forest (https://zkga.me/), Succinct (https://succinct.xyz/), Axiom (https://axiom.xyz/), and Personae Labs (https://personaelabs.org/) in creating public good software that has been shared with the wider community.
