I’ve started to deal with the technology of zero-knowledge proofs because I was curious if it was possible to create an anonymous, unhackable voting system on the blockchain. Paper-based voting (like the Elections) is a very expensive way of voting. …

A JavaScript tutorial — The technology of zero-knowledge proof and especially zk-SNARK is one of the most exciting ones in the field of crypto because of the following reasons: You can prove you have information without revealing it (for example, you can use it for anonymous voting). The proof is small and easy to…

Anonymity in voting is one of the basic requirements, but on a public network like a blockchain, it’s not trivial to implement it. Fortunately, the technology of zero-knowledge proofs (ZKP) makes it possible, but unfortunately, ZKP is a very complex technology. …

Prove Knowledge of a Private Key Without Signatures — In theory, a zero-knowledge proof (ZKP) can be constructed for any mathematical problem¹, without revealing this solution. In practice, developing a ZKP for a problem often requires the invention of a whole new cryptographic algorithm. It has no standard recipe and requires extensive and in-depth knowledge of cryptography. …

Upgrade Bitcoin’s Elliptic Curve Without a Fork and More This is the third installment of our collaboration with nChain. We would like to give special thanks to Dr Enrique Larraia for authoring the whitepaper this article is based on and helping guide the implementation. A standard payment transaction can be…

Zero-knowledge proofs are an important tool for us in decentralising ourselves. How do we maintain privacy when our platform stores data that’s globally transparent? What about scaling solutions that do work ‘off-chain’, which then needs to be confirmed by on-chain evidence? …

You’re a beginner in Cairo language, but you already knows solidity? This article will give you all the basis of Cairo (compared) to solidity in less than 3 minutes. Let’s start! What is Cairo ? Cairo is a new language for programming Starknet smart contracts. Starknet a L2 scaling solution for Ethereum. (by using…

Recently there is a rise in discussion about the potentials of ZKP — Zero Knowledge Proofs in crypto. Jumping on the bandwagon, I decided to learn circom and try to implement Conway’s Game of Life as a zkSNARK circuit, as well as use the circuit in an NFT smart contract. …
