4 . Advancing machines as a service Blockchain accelerates the possibilities of using an innovative pay-per-use model for machinery , often known as machines as a service ( MaaS ). In this model , instead of selling production equipment , a machinery provider charges for the equipment ’ s use on the basis of the output that it generates . For example , instead of selling a compressor , the machinery provider sells compressed air by volume . By relying on MaaS instead of owned machines , manufacturers can avoid large upfront investments and can easily upgrade equipment to gain access to the latest technology . If applied correctly , the MaaS model will allow manufacturers to scale their production flexibility effectively .
5 . Enabling machine-controlled maintenance Blockchain can support new maintenance approaches , like automated service agreements and shorter maintenance times . These innovations are necessary
to manage the greater complexity and technological sophistication of advanced production machinery . In order to facilitate outsourced maintenance , users append service agreements and installation documentation related to each device to the blockchain record , creating a digital twin of the device . Blockchain technology can then allow for the automated execution of and payment for scheduled maintenance . A machine that requires maintenance can trigger a service request and generate a smart contract for the work or for a replacement part . Upon fulfilment of the order , payment processing happens automatically . In addition , immutable documentation of the maintenance
