DREAM Paper

This work introduces DREAM, a novel construct that enables deletable content in otherwise immutable, decentralized storage systems such as Swarm. The paper contributes a new deletion model that is based on access revocation and presents a mechanism that allows data-sharing users to grant and later rescind access to specific data to specific consumers. The solution leverages Swarm’s distributed storage architecture to introduce a distributed one-time pad mechanism realized by a network protocol.
