-For a specific data NFT, multiple ERC20 datatoken contracts can exist. Here's the main concept: Owning 1.0 datatokens grants you the ability to **consume** the corresponding dataset. Essentially, it acts as a **sub-license** from the [base IP](../../discover/glossary.md#base-ip), allowing you to utilize the dataset according to the specified license terms (when provided by the publisher). License terms can be established with a "good default" or by the Data NFT owner.

License terms can be established with a "good default" or by the Data NFT owner.
 
 The choice to employ the ERC20 fungible token standard for datatokens is logical, as licenses themselves are fungible. This standard ensures compatibility and interoperability of datatokens with ERC20-based wallets, decentralized exchanges (DEXes), decentralized autonomous organizations (DAOs), and other relevant platforms. Datatokens can be transferred, acquired through marketplaces or exchanges, distributed via airdrops, and more.
 
-You can [publish](../../discover/glossary.md#to-publish) a data NFT initially with no ERC20 datatoken contracts. This means you simply aren’t ready to grant access to your data asset yet (sub-license it). Then, you can publish one or more ERC20 datatoken contracts against the data NFT. One datatoken contract might grant consume rights for **1 day**, another for **1 week**, etc. Each different datatoken contract is for **different** license terms.

 Furthermore, Ocean Protocol recognizes that different data assets may have distinct pricing needs.

 With the fixed pricing model, you have the power to set a specific price for your data assets. This means that buyers interested in accessing your data will need to pay the designated amount of configured tokens. To make things even easier, Ocean automatically creates a special token called a "datatoken" behind the scenes.&#x20;
