Blockchain has seen significant growth in recent years, and although it is still related by many to Bitcoin, the growth of companies and other digital currencies is visible, which has led some countries to initiate a legislative approach in order to protect companies and consumers. Thus, some countries such as Switzerland have included cryptocurrencies within existing legislation with some adaptations, others such as Estonia have used blockchain in almost all of their public services, or already accept Bitcoin as a payment currency, such as El Salvador and Germany. However, little is discussed about the situation of emerging countries, such as Brazil, which has a vast territory and its particularities, mainly because it is still a developing country. The general objective of the work is to discuss the advances and challenges in regulating blockchain technology in general, focusing on Brazil, which, as it is still a developing country, has an even more uncertain scenario for the adoption of new and disruptive technologies., which can greatly help the country’s growth and combat corruption.
