Cryptography Research - Zengo

Celebrating 1,000,000 Safe Customers, 0 Hacks. Learn more

ZengoX is a research group composed of researchers from academia and industry.Our goal is to take threshold cryptography all the way from theory to your mobile device (or any consumer software/hardware). We combine deep knowledge in applied cryptography and distributed systems security to push forward the usage and limits of Multiparty Computation (MPC).

Research Grants

Cryptography, security and research is at the heart of what we do. Zengo^x has received research grants from some of the leading projects in the crypto world. In addition, we received an R&D grant from the Israel Innovation Authority. We are committed to working hand-in-hand with all the builders of digital assets in order to provide the best native support and experience.

Our Projects

Battlement: A Quorum Based Design for Lightning Network Key Management

Security risks prevent entities with high liquidity from using the Lightning Network.
We propose an MPC-based solution.

Multiple Bugs in Multi-Party Computation: Breaking Cryptocurrency's Strongest Wallets.

We have uncovered and exploited 3 families of vulnerabilities in multiple open-source TSS libraries

Paper | Slides | Story (on Wired)

Social Threshold Recovery

We are exploring methods for recovering funds from threshold-based wallets.

JugglingSwap: Scriptless Atomic Cross-Chain Swaps

We are developing protocols to allow for atomic cross-chain swaps based on the gradual release of secrets.

Cryptographic Vulnerabilities in Threshold Wallets

We are identifying security vulnerabilities in threshold wallets, as well as developing solutions to overcome those vulnerabilities.

Secure Multiparty SpendAuthSig for ZCash

We are researching how to create an efficient protocol for using threshold signatures with shielded Zcash transactions.

GitHub | Paper | ZIP | Blog

This project focuses on researching how to use distributed networks for secure computation protocols.

ShareLock: Financial Privacy-enhancing

We are working on a practical, privacy-enhancing tool for cryptocurrencies which is deployable on today’s cryptocurrency networks.

The Myth of Threshold Wallets

We are researching a UC model for software and threshold wallets.
