(2023-12-20) Barbosa, Lucas dos Santos; Carazza, Luís Eduardo Barbosa; http://lattes.cnpq.br/1625397086677760; http://lattes.cnpq.br/6178087346414083
The Bitcoin attempts to challenge the fiduciary system by solving various problems associated with the centralized model. However, due to the blockchain's limited processing capacity, scalability issues abound. As a result, users are exploring alternative options to Bitcoin, including the Lightning Network (LN), a solution that offers fast and economical transactions. However, the Lightning Network is highly centralized and controlled by a handful of entities, raising concerns about privacy, security, rate adjustments, and government regulation. An alternative and popular approach is to engage in Bitcoin contracts through brokers, banks, payment institutions, and custodial wallet companies. While this method is more convenient, it raises privacy and fractional reserve issues. It is concluded that these applications of bitcoin contradict the principles outlined in the white paper and push the currency towards a fiat money model. In light of this, it is necessary to educate users about the benefits of using bitcoin in a decentralized way, encouraging the practice of peer-to-peer (P2P) transactions and self-custody storage.

The document also aimsto understand the potential changes in the economy from the use of such currencies, given that one of its main features is the alleged anonymity of users. Since there are no banks or governments centralizing operations, if a crime or infringement is committed, it is virtually impossible to track down, allowing many criminal organizations to see this kind of attractive trade. The lack of specific regulation laws also makes it difficult for users to enter, increasing the risk of investment. Yet despite thesefactors, virtual currencies still have a number of advantages that make them so popular and profitable, lower rates than traditional currencies, rising valuation, less bureaucracy, validity in any territory. These advantages offered to the user cause cryptocurrencies to be created, each serving a different audience. At the end of the course, the main barriers to the regulation and reliability of cryptocurrencies were raised and analyzed. Is this the new form of global negotiation, legal in all countries? Does this new way of transaction have the power to replace the ways transactions currently take place?
