Collaborative 3D modeling system based on blockchain.

We propose a collaborative 3D modeling system, which is based on the blockchain technology. Our approach uses the blockchain to communicate with modeling tools and to provide them a decentralized database of the mesh modification history. This approach also provides a server-less version control system: users can commit their modifications to the blockchain and checkout othersu0027 modifications from the blockchain. As a result, our system enables users to do collaborative modeling without any central server.
