João Vicente Meyer, Lucas Machado da Palma, Jean Everson Martina · 2020
The great extension of Brazil's territory, combined with its demographics of more than 200 million inhabitants, results in a complex, slow and expensive notary system. Blockchain technologies can be of huge help in this scenario. It provides a decentralized peer-to-peer way of storing and validating documents. In this article, we start the discussion about a blockchain-based national notary system with means to store and validate the natural person's public documents. We prototype a solution, comprising of birth, marriage, divorce, and death documents/certificates. In the end, we present a comparison between the operational costs of the implemented prototype and the current notary system.
