Shared Manufacturing is a new mode of social manufacturing based on the principles of a sharing economy. This paper presents a scalable framework for blockchain-based Shared Manufacturing that preserves the transparency and immutability characteristics of transaction records, which is critical to building trust between entities in blockchain-based systems. We define a blockchain-based protocol for the service execution according to the design principles of the sharing economy. We present a scalable integration of blockchain technology into the concept of Shared Manufacturing by employing cross-chain solutions. We discuss existing cross chain technologies regarding the requirements of Shared Manufacturing and propose hybrid approach. We compare implementations of the proposed framework on two different blockchain networks: Ethereum public network and Xdai sidechain network. We conduct user-oriented test to explore the performance (cost and time) of the implementations in realistic situations in order to justify the use of the sidechain technology. Results indicate that the implementation on the sidechains provides greater scalability than the implementation on the public blockchain network.

共享制造是一种基于共享经济原理的新型社会制造模式。本文提出了一种基于区块链的共享制造的可扩展框架，该框架保留了交易记录的透明性和不变性特征，这对于在基于区块链的系统中的实体之间建立信任至关重要。我们根据共享经济的设计原则为服务执行定义了基于区块链的协议。我们采用跨链解决方案，将区块链技术可扩展地集成到共享制造的概念中。我们讨论有关共享制造要求的现有跨链技术，并提出混合方法。我们在两个不同的区块链网络上比较了所提出框架的实现：以太坊公共网络和Xdai侧链网络。我们进行面向用户的测试，以探索现实情况下实现的性能（成本和时间），以证明使用侧链技术是合理的。结果表明，在侧链上的实现比在公共区块链网络上的实现具有更大的可扩展性。
