We're excited to announce the launch of our new product, Lock-Keeper! Where most cryptographic solutions are complicated and used to protect large-value digital assets, Lock-Keeper is a flexible, multi-layered digital asset management system that provides a...

We’re excited to announce a $9 million strategic partnership with blockchain gaming company, Forte, a leading provider of blockchain solutions for game publishers, to support its adoption of cryptographic technologies, including multi-party computation (MPC) and zero-knowledge proofs.

Today, we’re proud to announce that we are working to bring the zkChannels protocol to the Tezos blockchain. zkChannels is a chain-agnostic anonymous off-chain protocol that enables cheap and private value transfer between a customer and merchant.

In this post, we will provide a short background on multi-party computation and garbled circuits, explain how we utilize MPC techniques to build private payment channels and discuss how we chose an appropriate software framework to implement our MPC protocol.

Today, we proudly present zkChannels, a layer two protocol that enables privacy-preserving, off-chain Bitcoin and Zcash payments between customers and merchants. The protocol implementation is available on Bitcoin’s simnet and private testnet.

Blockchain-based cryptocurrencies like Bitcoin have privacy, scalability and latency problems that limit their use as a medium of exchange. Payment channel protocols such as the Lightning Network address these scalability and latency issues by using the blockchain to escrow funds and resolve disputes while moving the bulk of transactions “off-chain.”
