Purpose: The aim of this article is to present the concept of Decentralized Autonomous Organizations in the context of the evolution of organizational structures. The article presents the current state of knowledge about DAOs, taking into account the principles of their functioning and the current state of development. The roles of individual actors involved in the DAO were also discussed and typical features of the DAO organization were indicated. Design/methodology/approach: The main method used in this article is a literature review supplemented with an analysis of online industry sources and reports of consulting companies. The analysis included a review of the characteristics of the DAO organization against the background of traditional structures and the ways of functioning of the DAO. Findings: The article describes the characteristics of organizations managed with smart contracts created thanks to the use of blockchain technology. The stages of the formation of DAOs and the main principles of their functioning based on the possession of digital tokens of a given organization, as well as the right to participate in voting on decisions made in the DAO, were indicated. The basic advantages and risks associated with the functioning of DAOs were also indicated. Originality/value: The originality of this article lies in the confrontation of the theory and practice of DAOs with traditional, hierarchical organizations with specific features. The current literature in the field of DAOs is not very extensive, especially in relation to the issue of organizational structures, as demonstrated in the Materials and Methods section of this article.

Group signature schemes play a vital role in protecting identity privacy of a member of a group who signs a message using the group signature. However, in the existing group signature schemes the centralized group manager has control over all the participants, and these managers can be malicious. They may take a biased decision when there is a dispute among the group members or while revealing the identity of a group member. To overcome the trust issues related to centralized group managers and to improve user privacy, a decentralized group signature scheme (DGSS) is proposed by decentralizing the role of the group manager. The proposed scheme will be more suitable for decentralized environments like a blockchain. Security analysis along with the proof of correctness is also provided for the proposed scheme. A framework for a blockchain-based e-auction protocol using the DGSS is also proposed in this paper.

Zarządzający sektorem publicznym coraz częściej poszukują nowych możliwości oferowania mieszkańcom większego pakietu świadczeń, przyczyniających się do podniesienia jakości życia. Jedną z ich jest logistyka publiczna, która posiada potencjał integracji i koordynacji działań w zakresie realizacji zadań publicznych. Jednak obawy sektora publicznego względem prywatnego wykonawstwa świadczeń ciągle jeszcze są stosunkowo duże. Wynika to nie tylko z braku zaufania do zewnętrznego wykonawstwa zadań, ale także z braku transparentności relacji między sektorem publicznym i prywatnym, znajdującym uzasadnienie w teorii agencji. Sposobem na poprawę relacji i optymalizację oferty w mieście może stanowić technologia blockchain, która jest technologią rewolucyjną i przełomową, obiecującą zmienić sposób interakcji między interesariuszami miasta. Oferuje ona nowe alternatywy nie tylko kształtowania relacji miasto-społeczeństwo, wzrostu przejrzystości sektora publicznego, ale także ułatwienia przekazywania poufnych danych bez narażenia prywatności i bezpieczeństwa. W artykule podejmę próbę oceny możliwości zastosowania technologii blockchain w realizacji zadań publicznych oraz w codziennych kontaktach sektora publicznego z interesariuszami. Staram się wskazać możliwości technologii blockchain w kształtowaniu relacji między sektorem publicznym a społeczeństwem oraz podmiotami z sektora niepublicznego, zaangażowanymi w realizację świadczeń publicznych.

Managers of the public sector are increasingly looking for new opportunities to offer residents a larger package of benefits that contribute to improving the quality of life. One of them is public logistics, which has the potential to integrate and coordinate activities in the implementation of public tasks. However, public sector concerns regarding private performance of benefits are still relatively high. This is due not only to the lack of confidence in the external performance of tasks, but also to the lack of transparency in the relationship between the public and private sectors. This is justified by agency theory. A way to improve relations and optimize the offer in the city can be blockchain technology, which is a revolutionary and ground-breaking technology that promises to change the way interactions between city stakeholders. It offers new alternatives not only to shape city-society relations, increase public sector transparency, but also to facilitate the transmission of confidential data without compromising privacy and security. In the article I will attempt to assess the possibilities of using blockchain technology in the implementation of public tasks and in everyday contacts of the public sector with stakeholders. I tried to show the possibilities of blockchain technology in shaping the relationship between the public sector and society and entities from the non-public sector involved in the implementation of public services.
