Abstract
Nowadays, blockchain technology is expected to promote the quality control of traditional industry due to its traceability, transparency and non-tampering characteristics. Although blockchain could offer the traditional industry new energy, there are still some predictable difficulties in the early stage of its application, such as the structure of the blockchain-based system, the role of regulators in the system and high transaction fee by block packing. In this paper, we establish a pioneering quality control system for the green composite wind turbine blade supply chain based on blockchain technology. Firstly, the framework of this system is proposed to ensure that the quality of the product could not only be examined and verified by regulator, but also be monitored by other related nodes. Next, we develop a new way to store the data by hash fingerprint and the cost of transaction fees is significantly reduced in the case of a large amount of data. Then, the information on-chain method is developed to realize the data traceability of each node. At last, the tests of this system are carried out to prove its validity, the satisfactory results are obtained and information supervision and sharing role of the regulators are discussed.

Nowadays, blockchain technology is expected to promote the quality control of traditional industry due to its traceability, transparency and non-tampering characteristics
The main aim of this paper is to develop the quality control system of a green composite wind turbine blade supply chain, since few efforts have been carried out to establish this system
To the authors’ knowledge, the green composite product system based on blockchain technology which monitors the quality problem in the supply chain, the regulators’ role in blockchain based system, reducing the transaction fees of the Ethereum method, have been seldom found in the literature
Summary
The improvement of environmental protection consciousness and the promulgation of the related regulations have promoted the rapid development of new energy industries [1,2]. The work of wind turbine significantly relies on the quality of blade, which should be carefully controlled from raw material to final product in the supply chain. We propose a novel blockchain system in this paper to improve the quality control of the key nodes in the supply chain This new system develops the coordination between the regulator node and other nodes to ensure the traceability, transparency and prevention of data tampering, making the control of each node more efficient.
