This post was written by the AnonKlub team. One year and half ago, we embarked on an ambitious journey to explore the potential of zk-ECDSA in bringing enhanced privacy to the Ethereum ecosystem. This research initiative was introduced to the community through a blog post detailing the state of zk-ECDSA and its promising applications. As our research progressed and we began to develop practical implementations, our project evolved and was eventually rebranded as AnonKlub. This name change ref...

This post was written by Brechy. Thanks Nam Ngo for the feedback and review! Secure multi-party computation (MPC) enables a group of participants to collaborate on a specific task that requires their data as input, ensuring the privacy of their inputs and the correctness of the output.This allows performing operations on private information without disclosing it or involving a trusted third party. The only data each party receives is the function's result. There are several MPC protocols...

We are excited to share some updates on our road to building a zkEVM, as we generalize our exploration towards the design and implementation of a general-purpose zkVM. Zero-knowledge research and development in the broader Ethereum ecosystem has been bearing wholesome fruits over the past three years. That came after years of vibrant ideation with an uncompromising approach to security, building on the shoulders of giants of the prover-verifier computational model in computer science and cryp...

If you’re new to Anon Aadhaar make sure to read our initial announcement post.Introducing Anon Aadhaar v1.0.0Anon Aadhaar is a protocol that enables Aadhaar holders to prove their identity anonymously. It works by verifying the Aadhaar card's issuer signature, which is issued by the Indian government in formats like PDF, XML, and Secure QR code. These digital versions are signed using RSA, involving a pair of keys: a private key for signing...

This post was written by kichong with helpful feedback and comments from sinu and jmall. MPC, FHE, iO. If these combinations of letters make little sense to you, then you’re in the right place. This post attempts to review, at a high level, the world of programmable cryptography beyond the borders of zero-knowledge (ZK). The intent is to expose people to the idea that ZK is only one part of a constantly shifting landscape of cryptographic primitives, techniques, and protocols. And what remain...

This post was written by George Wiese and Artem Grigor. After Zero Gravity's 1st place finish at ZK Hack Lisbon in April, PSE recognized the potential of the Zero Gravity project and provided a grant for further research in the ZKML area. It's been an incredible journey since our team first ventured into the world of zero-knowledge proofs for Weightless Neural Networks (WNNs) at the ZK Hack Lisbon event. For an in-depth look at where we started, we recommend checking out Ben's ...
