Mittels Blockchain und IoT zum Decentralized Autonomous Building

Smart contracts are becoming increasingly important. They enable the unchangeable mapping and independent processing of legal contracts on an underlying blockchain technology. With the programming language Solidity, Ethereum offers a basis for Smart Contracts, on which many applications are developed and operated. This article looks at applications in the field of digitisation of the building industry and examines how autonomy of buildings can be achieved using Smart Contracts, Blockchain, and Internet of Things. Various aspects of the life cycle of a building from planning to construction to operation are considered and described by means of concrete application ideas as well as already existing implementations. The concluding discussion points shows open problems and gives an outlook on possible further developments.
