# Overview

Hedera is a fully open source, proof-of-stake, public network and governing body for building and deploying decentralized applications. 

It offers developers three primary services: Solidity-based smart contracts, consensus, and token services.\
\
It is considered a Layer 1 network and has its own native cryptocurrency HBAR.\
