Abstract: The use of e-commerce to enhance consumer relationships is becoming increasingly important in the information society. The constant development of technologies allows existing platforms to benefit from their characteristics; however, these advancements also bring various legal issues that must be addressed to protect users' interests and rights. Blockchain technology is revolutionizing B2C electronic relations due to its transnational nature, decentralization, guarantee of trust, immutability, and one of its most distinctive functionalities: smart contracts. These agreements are characterized by their automation and self-execution, features that can conflict with existing consumer and user legislation. Additionally, the opportunities provided by Blockchain, such as allowing users to act anonymously, may contradict regulations concerning the determination of international judicial jurisdiction and the applicable law for B2C consumer legal relationships. This work aims to analyze the applicability of smart contracts in e-commerce, particularly for B2C companies, and to study the potential issues they pose for current regulations, in order to determine whether these regulations need to be adapted for these technologies

Resumen: El uso del comercio electrónico para celebrar relaciones de consumo cada vez toma más protagonismo en la sociedad de la información. El constante desarrollo de las tecnologías hace que las plataformas existentes puedan beneficiarse de sus características; sin embargo, también traen consigo diferentes cuestiones jurídicas que deben mitigarse a fin de proteger los intereses y derechos de los usuarios. La tecnología blockchain es una de las tecnologías que viene a revolucionar el ámbito de las relaciones electrónicas B2C gracias a su carácter transnacional, descentralización, garantía de confianza, inmutabilidad y a una de sus funcionalidades más características: los smart contracts. Este tipo de acuerdos se distinguen por su automatización y autoejecución, caracteres que a priori pueden poner en riesgo la legislación existente sobre consumidores y usuarios. Asimismo, las oportunidades que brinda blockchain de cara a que los usuarios puedan actuar de forma irreconocible puede poner en jaque la normativa encargada de determinar la competencia judicial internacional y la ley aplicable a las relaciones jurídicas de consumo B2C. Este trabajo analiza la aplicabilidad de los smart contracts en el ámbito del comercio electrónico, en especial en el de empresas con consumidores (B2C) y estudiar los posibles inconvenientes que generan sobre la normativa existente a fin de analizar si es necesario adaptar la legislación a estas tecnologías

Exchange of information is a mechanism that enables tax authorities to share tax information across borders. Exchange of information curtails harmful practices such as tax evasion and tax avoidance by promoting cooperation between tax authorities. Recent world events have seen unprecedented levels of globalisation and novel income-earning structures. Taxpayers earn income from streams that were previously unavailable. These developments have led tax authorities to implement policies that focus on improved financial transparency and better multilateral cooperation. This article argues for the implementation of blockchain technology to facilitate exchange of information in South Africa. Blockchain is a ledger that records and stores information on an online network. Blockchain's features make it conducive for use in cross-border administration and exchange of tax information. Blockchain creates a platform for financial transparency because data stored on the blockchain is reliable and accurate. Tax information is exchanged in real time, thereby reducing tax authorities' administrative burden and enhancing cooperation.

Abstract Purpose: This article aims to analyze pioneering public finance initiatives based on blockchain technology, identifying the Brazilian context amid the international. Additionally, this study seeks to present opportunities for blockchain technology applications and the challenges encountered for their expansion. Originality/value: Few studies have covered the public sector, especially public finance, despite using and testing this technology in different areas. The development of these innovative applications is limited, particularly in Brazil. Design/methodology/approach: Public documents, such as reports and official websites of public agencies, associations, and institutions, were identified and selected from the unit of analysis “pioneering public finance initiatives based on blockchain technology.” Findings: Blockchain technology has been used in government projects related to research, identity, economic development, and financial services, among others. Blockchain initiatives have been led by Brazil’s financial, technology, and education/media sectors. Finding technology applications in public finance was one of the difficulties in the research. The number of projects in this category involving blockchain and the public sector is scarce in Brazil and internationally. However, this scenario has shown signs of change. Although reduced, public sector participation has increased in recent years. Blockchain has much to offer the public finance sector, but governments have been cautious and insecure about introducing the technology. It happens because of uncertainty about whether the technology is developed enough to withstand critical problems in the public system or what unique issues could arise from that technology.

Abstract Governments worldwide face recurrent challenges in incorporating environmental variables into bidding processes. In this context, sustainable public procurement is an important tool for reducing the environmental impact of public organizations. Despite the emergence of digital technologies such as blockchain, which offers potential solutions to complex public sector problems, and the existing implementation of blockchain in databases by some countries, the Brazilian government has not developed the capability to adopt such instruments to improve environmental effectiveness and efficiency. This study proposes a conceptual model for the application of blockchain in sustainable public procurement of road works to facilitate the incorporation of environmental criteria into bidding procedures. Through a content analysis of 25 bidding processes related to road works, the research mapped out key activities, providing insights to propose an integrated solution for the Brazilian National Public Procurement Portal to address environmental issues in procurement processes. The study’s main contribution lies in outlining potential applications of blockchain in public procurement to embrace environmental aspects, demonstrating the feasibility of implementing this technology. Given the emergence of new perspectives to optimize bidding process management and foster environmental sustainability in public administration, the research provides evidence that blockchain can help promote a reliable, decentralized, transparent, and environmentally sustainable bidding structure. context organizations problems countries efficiency procedures 2 activities studys s aspects technology administration reliable decentralized transparent structure
