State-governed blockchain for public procurement smart contracts

In many sectors like energy, transportation, social protection, health or education, public authorities are principal buyers spending an OECD average 14% of GDP through public contracts. Public procurement regulation has already developed electronic procurement proceedings like e-envoicing and e-payment methods, and the European Union is dedicated to go further on e-procurement. As an answer to the recent technology developments in supply chains, a logical step is to move the public procurement contracts from paper-basis to blockchain. Is it a vision or possible reality to introduce smart contracts to the world of public procurement? What advantages and obstacles can we see rising from this transformation? The paper is searching for answers but also raises even more questions.
