Shared manufacturing allows individuals to participate directly in manufacturing processes through peer-to-peer collaborations. In this thesis, we focused on the concept of shared manufacturing protocol based on blockchain technology using peer to peer communication. We present scalable framework for blockchain-based shared manufacturing that is solely relying on the use of smart contracts. Next, we propose our improvement of the protocol in which we propose the use of peer-to-peer communication in combination with smart contracts. With the proposed framework, we aimed at optimizing the protocol from a time and financial point of view. We implemented and tested both implementations of the protocol. For peer-to-peer communication we used Ethereum based Whisper protocol. The results confirmed that with the use of peer-to-peer communication the protocol can be sped up and can further decreases congestion of the blockchain network.
