Abstract: Embodiments provide a method and a system for distributing digital content. The method includes: receiving, by a content apparatus, a download request sent by a download client; determining based on the upload transaction identity and the license transaction identity, whether the download client has permission information of downloading the content file; if yes, sending the content file to the download client; after the content file has been distributed, sending a download transaction request to a content transaction processing apparatus; receiving, by the content transaction processing apparatus, the download transaction request, determining that the download information is valid, generating and sending a download transaction to a block chain processing apparatus; and adding the download transaction to a block chain. The content apparatus sends the content file only to the download client that has a download qualification, thereby restricting a distribution range of the content file.
