Brazilian National Council of Justice performed a survey in June 2014 verifying that court-ordered government debts reached the sum of US $26.28 billion. According to Brazilian Tax Law, court-ordered government debt is named "Precatório". These payment requests issued by the Judiciary are to collect from the Federal, State, and Municipal governments. The management of "Precatórios" is under the jurisdiction responsibility of Federal and State Courts of Justice under, that is, State Courts of Justice are responsible for organizing and maintaining a single list of "Precatórios" owed by the state and by municipalities that are under its jurisdiction. These lists are ordered chronologically, except for special cases defined by Law that have payment preferences. We believe that this is an opportunity for the application of blockchain technology. Blockchain can provide a system that is simplified, decentralized, autonomous, and trustworthy. If we consider that these court-ordered government debt payment may be used for tax payment, another major advantage of a national system that simplifies trade, exchange, and partitioning of is to make this market accessible to persons and small companies, instead of the dispersed bureaucratic payment lists regulated by different standards, inducing the support of specialists. This system would not change payment order, but it would allow a national trade and use that potentially may increase economic activities related to them. Hence, in this work, we propose a simplified model for the application of blockchain technology to "Precatórios" in Brazil. Additionally, we present a strategy for designing interdisciplinary applications of blockchain services.
