# Overview

Mezo is a Layer-2 blockchain built on top of Bitcoin with the goal of making Bitcoin productive in day-to-day finance. 

It is EVM-compatible, which means it can host decentralized apps (dApps) and smart contracts in a system that developers and users already understand.

You can find a block explorer for mainnet at <https://explorer.mezo.org/>

Here are links to Mezo's website if you want to explore their [user documentation](https://mezo.org/docs/users/) or [developer docs](https://mezo.org/docs/developers/).
