Governments spend plenty of resources and time on registering and managing the taxes of their citizens. Thanks to the use of blockchain technology, many proofs of concept are being implemented with which to automate processes such as those associated with the land registry. One of the problems of blockchain-based systems is the type of blockchain network to be used. Besides, legal problems arise due to the use of smart contracts that govern the platform. Also, the transparency provided by these blockchain-based systems can collide with the users' privacy rights. The present work focuses on providing solutions to those problems and on applying them to the Spanish land registry, by making use of stealth addresses, token ring signatures, and a permissioned network administrated by the Spanish state.
