摘　　要：As a disruptive technology,the blockchain is continuously finding novel application contexts,bringing new opportunities and radical changes.In this paper,we use blockchain as a communication infrastructure to support multi-party business processes.In particular,through smart contracts specifically generated by the mentioned business process,it is possible to derive a trustable infrastructure enabling the interaction among parties.Moreover,the emergence of different blockchain technologies,satisfying different characteristics,gives the possibility to support the same business process dealing with different non-functional needs.In this paper,we propose a novel engineering methodology supported by a practical framework called Multi-Chain.It permits to derive,using a model-driven strategy,a blockchain-based infrastructure,that can be deployed over a specific blockchain technology(e.g.,Ethereum or Hyperledger Fabric).The objective is to permit the single definition and multiple deployments of the business process,to deliver the same functionalities,but satisfying different nonfunctional needs.In such a way,organisations willing to cooperate can select the multi-party business process and the blockchain technology they would like to use to satisfy their needs.Using Multi-Chain,they will be able to automatically derive from a Business Process Modelling Notation(BPMN)choreography diagram a blockchain infrastructure ready to be used.This overcomes the need to get acquainted with many details of the specific technology.
