Implementing effective regulation of blockchain transactions has become a research hotspot in recent years. However, most of the current regulatory schemes are customized for specific blockchain applications and lack versatility and scalability. Meanwhile, these schemes cannot guarantee fairness due to the non‐disclosure of regulatory policies and regulatory processes. To address these issues, a scalable policy‐based regulatory architecture (SPRA) is proposed for blockchain transactions that separates regulation and application to provide sufficient scalability. SPRA is a four‐layer model (permission layer, regulation layer, bridge layer, and business layer). A regulatory policy description language (XRPL) is designed to define the regulatory rules and specifications for interoperability between the layers. A decentralized jury mechanism (JuryBC) based on the Shamir threshold secret sharing algorithm and Pedersen commitment is proposed at the regulation layer to avoid regulatory arbitrariness and unfairness. We also construct a secure and efficient regulatory data sharing scheme (RDShare) at the business layer using an attribute‐based encryption algorithm. The key parameters in both JuryBC and RDShare can be specified in the regulatory policy to suit different application scenarios. Finally, the security of the architecture is analyzed and the feasibility and scalability of the architecture through simulation experiments are demonstrated.

Blockchain technology is based on the idea of a distributed, consensus ledger, which it employs to create a secure, immutable data storage and management system. It is a publicly accessible and collectively managed ledger enabling unprecedented levels of trust and transparency between business and individual collaborations. It has both robust cryptographic security and a transparent design. The immutability feature of blockchain data has the potential to transform numerous industries. People have begun to view blockchain as a revolutionary technology capable of identifying "The Best Possible Solution" in various real-world scenarios. This paper provides a comprehensive insight into blockchains, fostering an objectual understanding of this cutting-edge technology by focusing on the theoretical fundamentals, operating principles, evolution, architecture, taxonomy, and diverse application-based manifestations. It investigates the need for decentralisation, smart contracts, permissioned and permissionless consensus mechanisms, and numerous blockchain development frameworks, tools, and platforms. Furthermore, the paper presents a novel compendium of existing and emerging blockchain technologies by examining the most recent advancements and challenges in blockchain-enabled solutions for a variety of application domains. This survey bridges multiple domains and blockchain technology, discussing how embracing blockchain technology is reshaping society's most important sectors. Finally, the paper delves into potential future blockchain ecosystems providing a clear picture of open research challenges and opportunities for academics, researchers, and companies with a strong fundamental and technical grounding.

The metaverse is a promising internet and social formation that aims to achieve a high level of synchronization and indivisibility between the virtual and physical worlds. In the ultimate stage of metaverse, a natural person acts as an avatar not only to conduct all kinds of activities across time and space in the virtual world but also to sense and change the physical world. Therefore, a genuine avatar serves as a trust anchor and is crucial for the organized advancement of the metaverse. Self-Sovereign Identity (SSI) is regarded as the promising scheme to build trust foundation for the metaverse, since it takes the trust anchor from a third-party organization back to a user, compared with the traditional digital identity management. Although the state-of-the-art SSI schemes already have appended the abilities of sybil-resistance, accountability, revocation or recovery, they suffer from privacy leakage and internal corruption due to a centralized authority involved. Futhermore, they failed to take into consideration high synchronization and indivisibility in metaverse. In order to construct a reliable and secure trust anchor for metaverse, a new self-sovereign identity scheme (NSSIM) with sybil-resistance, full lifecycle synchronization and joint accountability is proposed in this paper. Specifically, a genuine avatar generation protocol which provide one-to-one bound to a natural person is designed to achieve the sybil-resistance without violating privacy. And, an avatar behavior paradigm is devised to fulfill the full lifecycle synchronization between an avatar and the corresponding natural person, as well as protect his identity privacy. Furthermore, a joint accountability procedure is proposed to conduct fair, public and conditional regulation over avatar behavior paradigms. Finally, we analyze the security, properties of our scheme and conduct detailed experiments in term of the cost of computation and storage. The security analysis results indicate that our scheme resists all the known attacks. Compared with the state-of-the-art SSI schemes, our scheme fulfills all the SSI properties and the extensive experiment results show that the computation cost is small and the storage cost for privacy protection is acceptable.
