This normative paper conceptualizes an alternative for the current scientific peer reviewing and publication system. Based on design science research methodology, we propose a distributed peer-to-peer network and transactional data base system (APOLLO) and a cryptocurrency (APL). We conceptualize a market for peer-to-peer reviewing and publishing of research contributions and associated assets ...
