In Proofs, We Trust – Part 1

Here, we explore the concept of proof systems, which allow parties to convince each other by sharing verifiable evidence. It is extremely unlikely that anyone reading this document has stood in the presence »

Zero Knowledge Proof of Age Using Hash Chains

We demonstrate a zero-knowledge proof of age protocol that could be easily implemented on a proof of process network. In a recent post, we outlined a technique of proving that a hidden value »

Zero-Knowledge Proof of Balance: A Friendly ZKP Demo

Here at Stratumn Research we are currently applying various cryptographic primitives to allow participants finer control over their confidential information, even when it is shared in some way. Our general approach is to »

Zero-Knowledge Explained – Part 1: Use Cases

With a zero-knowledge protocol, sharing proofs without data and the selective disclosure of information offer possibilities for businesses to work together in an interconnected world Innovation: Gradual and Sudden Whether in the fields »

Beyond Decentralization: Prover-Verifier Systems

Richard Caetano and I presented Stratumn research on Proof Systems at the Ethereum Developer Conference in Paris on 18th of February, 2017. It was titled, "Going Beyond Decentralization with Prover-Verifier Systems." This post »

Breaking out of Distributed Ledgers

When thinking about “revolution”, we can picture how a wheel turns. By starting with some momentum, we turn through the first 180 degrees as we accept the status quo. Then, turning through the »
