Funding Amount: 100k $S


Peer-to-peer (P2P) storage is a paradigm to leverage the combined storage capacity of a network of storage devices (peers) contributed typically by autonomous end-users as a common pool of storage space to store and share content, and is designed to provide persistence and/or availability of the stored content despite unreliability of the individual autonomous peers in a typically decentralized environment. Besides the basic reliability guarantees of persistence and/or availability, a feature rich P2P storage system may need to support other functional requirements depending on application needs. Some such functional requirements include:

•Transactional access, concurrency and consistency issues

•Security features such as:

◦Fine grained access control
◦Content validation (e.g., against pollution)
CrowdStore is our ongoing project to realize a security features rich persistent p2p storage centric internet infrastructure.
