Croquet Project has not been under active development. All further development of the technology has occurred under the Open Cobalt effort. Croquet is a software development kit (SDK) for use in developing collaborative virtual world applications. Applications created using the Croquet SDK are automatically collaborative since application objects in Croquet share a common protocol allowing them to cooperate with each other by employing the principle of replicated computation (synchronization) together with a peer-based messaging protocol. The technology is designed to facilitate such replication between peers, to greatly reduce the overhead needed for widespread deployment of collaborative virtual worlds. This efficiency, combined with
