What is Retrieval Miner (Filecoin)?

Retrieval miners, along with storage miners, are the two key components that make up Filecoin's decentralized market structure. The Filecoin network benefits three main groups of users: (1) Retrieval miners who receive tokens by serving data, (2) storage miners, who receive tokens by providing storage, and (3) clients who pay to store and retrieve data. The retrieval market is built off-chain, and is powered by retrieval miners who help transmit data back and forth.
