A journal-as-a-service platform that revolutionizes the creation and management of scientific journals. Building upon and advancing beyond traditional systems like the Open Journal System (OJS), The DeSci Journals simplifies the process by leveraging web3 principles and technologies. Our platform enables communities to operate as digital cooperatives for publishing high-quality, peer-reviewed content produced by scientists and technical professionals working for companies or in Academia. By empowering collaborative creation of scientific publications through this cooperative model, The DeSci Journals ensures that contributors maintain 100% ownership of their copyrights. This approach allows content creators to have full control over their work while providing opportunities to monetize their contributions and share in the gains from their publications. By utilizing web3 primitives, The DeSci Journals enables the creation of scientific portfolio assets, allowing contributors to build and showcase their body of work in a secure and decentralized manner. This feature enhances the value proposition for content creators by providing them with tangible assets that represent their scholarly contributions. Offering a modern, decentralized alternative to legacy systems, The DeSci Journals enhances accessibility, transparency, and equity in scientific publishing. Our journal-as-a-service model streamlines journal creation and management, fostering a more inclusive and collaborative environment for disseminating scientific knowledge globally.
