# Peer

## Introduction

A Peer is a Network entity that maintains ledgers and runs chaincode containers in order to perform read/write operations on a ledger they maintain. Peers are owned by Organizations, and act as an Organization's endpoint to transact on the Channels to which they are connected to.
