A Blockchain-Based e-Government Service for Quantity Surveyors

In Spain, quantity surveyors are entitled to carry out official cadastral surveys, attestations, and certificate issuing according to a well-defined professional code. The Official Associations of Quantity Surveyors and Technical Architects (COAATs) are responsible for endorsing the documentation related to actions performed on buildings. An e-platform that enables immutability, traceability, and a unique property record among all the Spanish COAATs, with an affordable cost, is essential to streamline the involved processes.
