The project has involved a study on blockchain technology to be applied in BIM projects as well as to obtain an alternative solution to the certification and digital signature processes being implemented in the Ministry of Justice. 

Blockchain is the name of a technology that enables decentralized and distributed record keeping of digital transactions.  Its use in BIM projects makes it possible to digitally sign projects, support the certification processes and provide them with capacities to protect the knowledge contained in them; and it also offers the Ministry of Justice a solution that is more efficient, cheaper, more reliable and elastic than its current solution and that would allow it to solve its performance problems.

As part of the project, a study was done of public blockchain networks and an analysis of free blockchain implementations was carried out. An application that is capable of signing documents and which can be deployed both on public and private networks was developed. A web application that can be run in a browser and that allows the hosting of BIM files in a blockchain was also developed.
