# 15-3 Data Ownership : Public / Private

DonaBlock Data generated in the ecosystem are categorized in two ways by ownership:

the privately owned or the publicly accessible. For example, the purchase transaction details

of a customer are exclusively accessible by the customer and by limited, authorized parties

only, which are managed as private data. However, the open access data like deal information and sales contents are considered as public data, which are accessible by all participants or contributors on DonaBlock.

This public data includes a summary of important matters related to the products on sale to share transparent data, and it does not include any private, personal information. Private data is stored securely on a separate distributed storage, and only the reference of the data - hash or address - is stored on blockchain.
