I thought about a kind of recoverable-property decentralized system which makes you confident that losing private key is not a problem anymore. Just like you lose your facebook, you can easily recover it by email or phone number. But it was almost at a standstill and I gave up. Two months ago, I was working on Ethereum privacy…

Part 1. The ideas behind zkSNARKs: Zero-knowledge proof To start on journey, we need to clear a confusion that a lot of people still make about Zero-knowledge proof (ZKP) and zkSNARKs. They have connections, but are different definitions. ZKP is a method or protocol by which one party (Prover) can prove to another party (Verifier) about a true statement without revealing the statement’s value. As for zkSNARKs, zkSNARKs is a scheme running on the idea of…
