A fully decentralized algorithm to timestamping transactions in a peer-to-peer environments

In this paper, we investigate a decentralized approach to timestamping transactions in a replicated database, under partial replication in Peer-To-Peer (P2P) environments. In order to solve problems of concurrent updates and node failures, we propose an architecture based on quorums, this architecture allows assigning a unique timestamp to each distributed transaction, to select the servers replicas and to coordinate the distributed execution of the transaction.
