Secure and Safe Blockchain Service Infrastructure

Abstract

The development of the online cyber society has been remarkable, and the internet has become an essential social infrastructure for various countries. However, due to the slow response to security challenges, various fraudulent and illegal uses, as well as malicious and irresponsible actions and statements, have proliferated. This paper proposes the SSBSI blockchain service infrastructure, a platform aimed at creating a safe and secure cyber society, addressing two key challenges of the current online cyber society: the strong anonymity of users, which makes it difficult to identify problematic actors and speakers, and the accumulation of personal information and privacy data by service providers, a major cause of frequent personal information leaks. SSBSI is a blockchain service infrastructure concept that incorporates mechanisms for reliable user identification, coexistence of anonymity and identifiability, and user-controlled management of personal information and privacy data. On the other hand, the EU established the EBP (European Blockchain Partnership) and started developing the EBSI (European Blockchain Services Infrastructure) for reliable public services across the EU, with some services already operational. This paper summarizes the relevant specifications of EBSI and discusses its similarities and differences with SSBSI.
