 ## Overview
 
-To publish assets on the Ocean Marketplace, publishers must provide a link(an URL) to the file. It is up to the asset publisher to decide where to host the asset. For example, a publisher can store the content on their google drive, AWS server, private cloud server, or other third-party hosting services. Through publishing, the URL of the asset is encrypted and stored as a part of DDO on the blockchain. Buyers don't have access directly to the URL, but they interact with the Provider, which decrypts the URL and acts as a proxy to serve the asset. The DDO only stores the location of the file, which is accessed on-demand by the Provider. Implementing a security policy that allows only the Provider to access the URL and blocks requests from other unauthorized actors is recommended. One of the possible ways to achieve this is to allow only the Provider's IP address to access the URL. But, not all hosting services provide this feature. So, the publishers must consider the security features while choosing a hosting service.
