dARK: uma implementação descentralizada de identificadores persistentes ARK baseada em blockchain

Abstract

We present the first proof of concept of a technology that could be thebasis for a decentralized, low-cost service for assigning/resolving persistent ARKidentifiers. This is the basis for an open, community-driven project promoted by IBICT(Brazil) and LA Referencia/RedCLARA with the long-term goal of providing anopen/non-centralized persistent unique/duplicate identifier factory and resolutionservice for the global Open Science ecosystem based on permissioned publicblockchain technology. Some of the motivations for this work are: (i) The need for notonly persistent, but unique/deduplicated identifiers in order to build better researchgraphs, indicators and research evaluation data; (ii) Lack of coverage of PIDs inrepositories of the Global South mainly due to the costs that these services representfor institutions; and (iii) Most persistent identifier systems are based on centralizedmodels, depending on a few agencies that support the service infrastructure. TheARK identifier has emerged as a viable alternative low-cost solution due to thepossibility of implementing internal providers for the global resolver. dARK is an ARKimplementation based on institutional blockchain nodes, the data is owned, storedand controlled in a distributed manner by all the organizations maintaining thenetwork, without the need for intensive use of computing resources.
