In the Italian legislative process, documents exchanged between institutions such as the Senate, the Chamber of Deputies, the Prime Minister's Office, and the Ministry of Justice are not managed through a unified database system. This fragmented structure — required by the constitutional imperative to maintain separation of powers and by security and redundancy concerns — produces substantial inefficiencies in document exchange, traceability of legislative history, and public accessibility of regulatory information. This study examines whether blockchain technology can at least partially address these inefficiencies. Building on the xLeges project, an avant-garde P2P architecture for the electronic transmission of legislative documents developed since 2014 under the Italian government's Normattiva programme, the research analyses how blockchain properties — immutability, transparency, decentralisation, and security — can enhance interoperability among institutional actors, provide tamper-evident versioning of legislative acts, and facilitate document retrieval by both institutional operators and citizens. The paper assesses the technical and legal feasibility of such an implementation and draws on comparative analysis of blockchain applications in other jurisdictions.
