“…These access rights are specified by the owner of the group, and each group member performs operations based on the information specified. In recent years, research has been conducted to provide collaborative services where group members work together through handling shared resources on group workspaces [10,11].…”

“…Lets3D [5] is a 3D collaborative editor developed as an extension of the Three.js editor [6], which is an open source JavaScript application running on Web browsers. To provide Three.js with collaborative features, Lets3D uses the whiteboard service of C3ware [10], which enables a group of users to edit and share 3D objects and 3D scenes in real time. Lets3D also relies on the Openfire XMPP messaging server to create a group for collaborative editing and to synchronize the editing screens of the members of the group through XMPP messages.…”

“…This paper is the extension of our previous work [9]. To manage user/group information, the Openfire XMPP messaging system is used in Lets3D, and the whiteboard service of C3ware [10] is also used in Lets3D to support collaborative editing functionality. But the use of these centralized middleware might cause the single point of failure, which can be overcome by state machine replication provided by distributed consensus.…”

As 3D modeling has been popular, collaboration in 3D modeling is also getting more attention. As one of such efforts for collaboration support, Lets3D enables a group of users to edit 3D scenes in real time with the help of collaborative middleware. In this paper, Lets3D-C, a new version of Lets3D is introduced, which utilizes the Raft distributed consensus protocol. Lets3D-C is composed of two modules: editing module for 3D editing functionalities, and consensus module for supporting the robustness of collaboration in case of node or network failure, whereas Lets3D is exposed in a single point of failure due to the use of centralized middleware.

“…Since various kinds of resources generated through distributed applications are stored in the Ethereum blockchain network, it is practically impossible to forge or falsify the stored data [5]. This feature has a great advantage in analyzing the history of group work in which users share resources together, and does in analyzing the contribution factors of group members [6] [7]. Ethereum-based group workspaces can support reliable collaborative environment among group members because users' working histories of shared resources are stored in the blockchain network without falsification.…”
