Tuesday,9 in February 2021 The Blockchain Network as a Tool for Social Responsibility and Development of South America In the last years, we have seen a significant increase in the development of the blockchain network around the world. Blockchain is a ledger of decentralized transactions maintained by a shared database system that are linked in a peer-to-peer network. Blockchain, therefore, is the name given to the data structure behind, for example, cryptocurrencies, such as the Bitcoin. However, although the most common type of transactions made on the blockchain network is in the form of money, there are many other possibilities fields for its use, such as energy, logistics, healthcare, food industry, and copyright protection. As a result, the impact of an eventually grow in the blockchain network in Latin America is of significant relevance. The blockchain market has been growing exponentially in Latin America. In June 2019, the Brazilian startup Rhizom developed the first blockchain network fully written in Latin America, with the goal of connecting companies from different countries of the region to benefit from the new technology. In addition, in 2013 the Latin American Bitcoin & Blockchain Conference (LABITCONF) was created in order to bring together the best minds in the blockchain industry, to convey and discuss the keys to a prominent future of the area in the region. The last conference was held in Uruguay, during the last December, with the participation of important industry players from more than 20 countries, including members of governments and CEOs of several blockchain-related companies. The growth of the blockchain network in Latin America comes at a pertinent moment for the region. During the last years, the world has seen alarming waves of protests throughout several Latin America countries, such as Brazil, Chile, Bolivia, Venezuela, Colombia, and Ecuador. Beyond others, Latin America citizens’ complaints are regarding the large corruption network inside government bodies. Acts of corruption are facilitated due to the centralized monetary system, where malicious people who know how the system works manage to control it and manipulate it according to its own interest, due to the difficulty of verifying the legitimacy of large and complex transactions. The blockchain system helps in solving this major issue since, as the name predicts, every transaction made is registered in blocks. A certain transaction will only be legitimate when the shared network verifies it and compares this specific transaction to its digital past- or “blocks”-, and confirms the licit track. Moreover, different Latin American countries, as many other states of the planet, have distinct currencies, with divergent bureaucratic systems, making the interaction between countries’ systems harder to make. This creates an anomaly, where simple transactions are done in a ridiculously slow speed, with a significant amount of taxes and fees. Differently, the blockchain network has a singular system of communication, fast and effective, in a more transparent and clear structure. Developing countries are doubtlessly positively impacted by the use of blockchain technology, where it helps to (re) build a stronger feeling of trust between different society parts. In addition, due to its decentralized public owned network with a shared infrastructure, it is not influenced by corrupt politicians. The enlargement of the blockchain network as a tool for social responsibility and development is of immense importance as part of better development of Latin America countries, with the potential to reach, in a relatively short period of time, great impacts for the region and for the other parties involved in the process.
