> Documentation for connecting to and operating on the Malbec Labs / DoubleZero network — validator and tenant setup, multicast, rewards, geolocation, and contributor operations.

## Welcome

- [Welcome](https://docs.malbeclabs.com/index.md): DoubleZero is a high-performance decentralized protocol and network optimized for distributed systems like blockchains, offering optimized transmission and pre-processing of distributed systems data.

## Quick start
