Once a tower has been digitized and created as an asset in TrustOS, the use of blockchain makes it possible to easily certify and audit not only its current status, but also the history of the actions carried out on it. With the help of the Tower Automation Alliance, the digitization and traceability model on Blockchain used by Telefónica Tech and Atrebo will become the market standard for auditing this type of information and will greatly facilitate future valuation exercises of this type of infrastructure in M&A operations. The availability of this individualized traceability information will even make it possible to discriminate between the different towers and estimate higher or lower returns depending on their locations, the equipment incorporated, its state of conservation or the accumulated issues and repairs.
