This paper presents the design of a P2P data persistent platform. Durable access and integrity of the data are ensured despite massive attacks. This platform, named DataCube, exploits the properties of cluster-based peer-to-peer substrates to implement a compound of full replication and rateless erasure codes. DataCube guarantees durable access and integrity of data despite adversarial attacks. In particular, the recovery of damaged data is achieved through the retrieval of coded blocks whose integrity is checked on the fly.
