Blockchains (BC) and Decentralised Ledger Technologies (DLT) are being included in several real-world scenarios, not only in the financial context but also in several others, such as healthcare and supply chains. The characteristics of these technologies that encourage exchanges and transactions between participants without the need for a third party (central authority) have raised increasing interest in the application of technology to a wide range of organizational, inter-organizational and societal problems. However, even if important digital, organizational and economic transformations can be anticipated, the impact of the introduction of these disruptive technologies is not yet well studied. This project intends to analyze the organizational and social impact of the inclusion and use of Blockchain (BC), Decentralised Ledger Technologies (DLT) and smart contracts in information systems. Interviews, surveys, analysis and testing of a set of BC and DLT tools will be conducted in order to justifiably position them in the context of existing Technology Adoption Models (TAM). This project is in line with the Thematic Line 5 - Digital Transformation of the SocioDigital Associated Lab.
