​zkDatabase uses a distributed storage engine that improves the availability of data. It utilizes Zero-Knowledge Proof to ensuring the correctness of data in verifiable manner. With zkDatabase, it's allow developers to focus on developing their ideas, rather than managing the complexities of data storage and management.

​SocialCap aims to solve the challenge of verifying the authenticity of credentials in the digital world.

​Our community-based attestation protocol, complemented by a user-friendly zkApp, enables easy self validation and issuance of credentials using a transparent and repeatable process, while preserving privacy and confidentiality.

​We would like to showcase our product to the MINA community in order to gather feedback on how we can improve it and to better understand how the ecosystem can benefit from it.

​Additionally, we would appreciate the opportunity to discuss design decisions concerning the UI/UX and the overall architecture.

​We believe that these discussions could be valuable to others who are facing similar challenges that we encountered during the development process for MINA.

ZkProtest is a privacy-focused decentralized zkApp built using SnarkyJS, zero knowledge proofs, and deployed on the Mina blockchain.

It aims to enable anonymous and secure protests where participants can join and support various causes while preserving their privacy.

As a result, ZkProtest allowing users to join and support causes without compromising their personal information.

Privacy preserving, accountable, untraceable

Imagine that you could prove you have a doctor's note without revealing the doctor's details or specialization. Made a small Zero Knowledge Application to do just that!

From Kartik.
- I’m creating a smart contract that has a function which allows patients to pass in their virtual sick notes, provided by their doctors
- The smart-contract asserts a real doctor provided the sick note.

In More Detail:
Doctor Registry
- We’re first creating a registry of doctors in the leaves of a Merkel-tree. These will only be mutable by a single entity, known as the CPSO (https://cpso.on.ca taken from A doctor association in Canada) and forms the foundation of our security model/assumptions.
- We don’t highlight it in the code, but the Merkel tree would be hosted publicly in practice
Verification Process
- The patient-client would pass in a Merkel Witness for the doctor that provided them with the sick note.
- This would remain a private input
- The code/verification function checks the validity of the Merkel-Inclusion Proof by ensuring the tree root, which is currently a public state variable matches the Merkel Witness root.
- If this assertion passes, we check if the doctor’s note that is passed in was truly provided to the patient by the doctor.
- We do this by running Verify on the signature.

Imagine that you could prove you have a doctor's note without revealing the doctor's details or specialization. Made a small Zero Knowledge Application to do just that!

Mina's zkApps are smart contract applications powered by zero knowledge technology, which offer privacy, security and verifiability for users. Join the Mina community in Denver and learn about ZK, use cases, and starting building your first app during this hands-on workshop.

In part 2, I show you how I got stuck, overcame the problem and then got stuck again.😅

I managed to connect to a Metamask wallet in a frontend using react, and get all the holders of an NFT collection using alchemy.

This is a hackathon series that I recorded while participating in the MINA zk ignite builders program (cohort 0).

Check out part 1 to see how I came up with an idea for a privacy app using zk proofs (zk app).

This is part 1 of a series where I walk you through (maybe a bit haphazardly) the steps one might take when competing in an online programming competition or hackathon.

In this episode, I walk you through the ideation phase.

This was for a program called zk ignite (cohort 0) where you create blockchain apps utilising zero knowledge proofs (zk apps) on the Mina Blockchain.

Curious about Zero Knowledge Proofs but you haven't spent time learning about it yet? In this video, Jen and I present our apps that use zero knowledge proofs on the Mina Blockchain. We built these apps as part of a programme, hosted by O1 Labs, which taught how to build ZK apps on the Mina Protocol.

These apps were created with Typescript and we were both new to zero knowledge proofs and building with SnarkyJS prior to this programme.

What do you think about Zero Knowledge Proofs?

Designing simple and expressive libraries is hard, but is a worthy goal. It's too easy to accidentally add complexity. Math can fix that. Math can give us guide-rails that point us to an ideal simple and expressive design. In this talk, we'll use basic abstract algebra to guide us toward a simple and expressive animation library. We'll use animations to help us understand abstract algebra as we discover the true algebraic structure of animations. Only after thinking hard about the structure, do we begin an implementation. In the end, I'll present some examples of working with this animation library we derived over the talk.
