ABSTRACT
Big data has been a game changer of machine learning. But, big data is a form of centralized version of data only available and accessible to the technology giants. A way to decentralize this data and make machine learning accessible to the smaller organizations is via the blockchain technology. This peer?to?peer network creates a common database accessible to those in the network. Furthermore, blockchain helps in securing the digital data and prevents data tampering due to human interactions. This technology keeps a constant track of the document in terms of creation, editing, etc., and makes this information accessible to all. It is a chain of data being distributed across many computers, with a database containing details about each transaction. This record helps in data security and prevents data modification. This technology also helps create big data from multiple sources of small data paving way for creating a well serving artificial intelligence model. Here in this manuscript, we discuss about the usage of blockchain, its current role in machine learning and challenges faced by it
ABSTRACT
This research paper revolves around several factors that affect cryptocurrency and its efficiency shortly. Many great scholars have talked differently about this concept. To find where cryptocurrency is bound to be, a survey was conducted with necessary questions and a total of 200 responses were received which in turn, helped us to analyze and interpret various economic and social factors impacting its standing in the business sector. Certain limitations and suggestions were generated at the end of the research analysis, followed by the conclusion. It also explores the users' confidence in dealing with cryptocurrency in a time when the usage of such virtual cash was not fully managed and regulated. Besides, the paper is aimed to measure the spread of cryptocurrency use to have a clear photo from the practical view. The paper additionally analyses how certain remarkable international locations have responded in terms of recommendations
ABSTRACT
Os problemas socioecológicos são complexos e multidimensionais, envolvendo pelo menos a dimensão ambiental, social, econômica, política e institucional. Os problemas relacionados ao uso múltiplo dos recursos hídricos, a revitalização de bacias hidrográficas e a recuperação de rios urbanos têm colocado novos desafios para a sociedade, os quais requerem soluções inovadoras. Algumas soluções propostas, como a adoção de esquemas de Pagamento por Serviços Ambientais (PSA), têm por objetivo incentivar que as pessoas adotem ações direcionadas para resolver problemas específicos em troca de incentivos econômicos. Mas essas soluções possuem limitações relativas a continuidade das ações após o suprimento dos incentivos. Os PSA tradicionais são baseados na moeda oficial de um país e, consequentemente, podem ser interrompidos na ocorrência de crises econômicas. Nesse sentido, o objetivo principal deste trabalho é apresentar e discutir uma proposta geral de gestão para a Bacia Hidrográfica do Rio Jundiaí baseada na adoção de uma moeda complementar criada com suporte da tecnologia do blockchain. A moeda complementar é a criptomoeda denominada Aqua que visa incentivar ações, por exemplo, como a recuperação das áreas de proteção ambiental em áreas rurais, assim como, ações ambientais em áreas urbanas. A criptomoeda Aqua busca exercer a função de meio de troca e sua circulação ocorrerá somente dentro da rede de usuários que a aceitarem. Visando evitar o efeito negativo de ações especulativas, recomenda-se que a criptomoeda Aqua não seja conversível em reais ou outra criptomoeda.
Socioecological problems are complex and multidimensional, involving at least an environmental, socio, economic, political and institutional dimensions. Proble-ms related to multiple uses of water resources, watershed revitalization and urban river recovery have placed new challenges on society and require innovative solutions. Proposed solutions, such as payment for ecosystem services (PES), aim to encourage people to adopt actions to solve specific issues in exchange for economic incentives. These solutions have limitations related to continuity of actions after the economic incentives cease. Thus, the main goal of this paper is to introduce and discuss a proposal to manage the Jundiai River Watershed that includes the adoption of a complementary currency created with blockchain technology, the Aqua. The main purposes of this cryptocurrency arethe recovery of riparian forests in rural zones and environmental actions in urban areas. The cryptocurrency Aqua would act as a medium of exchange and circulate only within the network of establishments that accept it. Seeking to avoid the negative consequences of speculative actions, we recommend the Aqua is not convertible into Reais or other cryptocurrencies.
