This paper deals with the development (specification, implementation and evaluation)
of a web application that should act as a decentralized scientific publisher, using Blockchain
technology for intelligent contracts and hypermedia storage. The security of stored data is
a concern in many software, which has contributed to a better understanding of distributed
processes and softwares. Data storage systems that use Blockchain technology emerge as an
alternative to ensure information integrity through decentralized storage, auditing, and transparency.
Decentralized applications have proven to be more efficient, safer and cheaper. This
discussion extends to the scientific community in the scenario of publication and revision of scientific
articles. Researchers use publishing tools to publicize their work and want to gain some
control over profit, copyright, and content review. With Blockchain, solutions such as Hyperledger
and IPFS (Interplanetary File System) enabled the management of this content through
the logics of a traditional publisher in an autonomous, decentralized and secure way. This
work is the proof of concept of a broader research carried out in the GERCOM laboratory at
UFPA, the DASP (Decentralized Autonomous Software Publisher), which aims to broaden the
management of the editorial process, removing intermediates, in order to optimize the process
between the entities involved (community). The system developed in this work allows authors
to register and allows them to submit articles to the IPFS network to have their hash stored in
Hyperledger Fabric where it will be available to be evaluated by registered reviewers on the
network through the rules of the smart contract. The implementation of the code was done in
the Javascript language (NodeJS), with the help of the Dependencies: angular4, react, go-ipfs,
hyperledger-composer, the database is IPFS for hypermedia and Hyperledger Fabric for transactions,
participants and assets . The implemented system was validated through the technical
evaluation of the elaborated diagrams and by evaluation questionnaires with real users, in a
scenario that contemplates the sending, revision and publication of a scientific article, in an
intranet.
