Wild Card's description 
P2P (Peer-to-Peer) is a technology that fosters self-deployment and self-organisation, thus, it is reducing operational costs, while it achieves optimised resource utilisation for the deployed applications and services.Therefore P2P network became the predominant technology for the data sharing, storage and management worldwide. Everybody counts on that that the data are situated somewhere in the net, but nobody takes care where exactly it is and wheather it is infallible and secure enough. Nevertheless, potential failure of such system, techical or intentional, may lead to irretrievable loos of data in global scale.
