Fluxos da informação orgânica e tecnologias descentralizadas Blockchain no contexto da Arquivística pós-custodial

Since the late 1980s, Archives have undergone a series of conceptual changes based on the development of new theoretical approaches to the understanding of archival document concepts and archival functions. In the context of the paradigm that has been called post-custodial, the fundamental concepts enshrined in the Archives need new interpretations for the production of meaning. In this scenario, new possibilities are introjected through information and communication technologies, which directly and proportionately impact archival methods (Cook 2012). The established archival principles, such as provenance, archival linkage, that is, organicity (Duranti 1997), are questioned, since the change promoted through information and communication technologies about the materiality of organic information also implies changes in the structure of documentary media, in the information flow and in management needs. In the context of new technologies, we focus on Blockchain, a protocol of authenticity based on the decentralization and distribution of data records in a shared preservation and authentication structure. Currently, it is used in corporate business environments as a tool for data preservation, Blockchain entails a series of problems regarding the adequacy of its procedures with regard to guaranteeing the preservation of the chain of custody of archival documents as an essential element to the maintenance of the provenance and archival links. This work has as its theme the analysis of organic information flows within the Block chain, considering the possibilities of flow mapping and the possible ruptures provoked in the archival principles. As a general objective, the characteristics of the information flows of digital archival documents preserved in a blockchain environment were analyzed. To fulfill this general objective, we have specific objectives: a) to describe the theoretical aspects regarding the blockchain, regarding applications, structures and strategies for implementation; b) investigate the conceptual bases of post-custodial archivology, in the context of technology block block technology; c) demonstrate the relevance and implications of the blockchain in mapping the flow of organic information. As methodological procedures, a bibliographic research was carried out, theoretical and of pure nature, documentary, exploratory and qualitative, based on the national and international scientific literature published in books, theses and dissertations. As a result, blockchain technology is evident in applications in the context of archival, such as encryption and tracking the flow of organic information
