# Glossary of Terms

The protocol uses specific terms to refer to different concepts.  Below are some of the terms you should become acquainted with.

#### Reaction

This is the core primitive of the RARA protocol. Reactions are one-time use ERC-1155 tokens that power curation in RARA.

#### Maker

A maker is the address that owns an NFT that is [registered](https://docs.rara.social/protocol-features/register) as a reaction in the protocol. 

#### Creator

A creator is the address that minted and created an NFT. 

#### Curator

A curator is the address that [reacts](https://docs.rara.social/protocol-features/react) to curate NFTs into the protocol. Spending a reaction on an NFT is the act of "Curating".

#### Taker

A taker is the address that owns an NFT that curated with Reactions. 

#### Referrer

Any application can integrate the RARA protocol as a referrer as further detailed in [Optional Curation Incentives](https://docs.rara.social/protocol-features/optional-curation-incentives).
