<p> Non-Fungible Tokens (NFTs) do hold the promise of providing Web3 with the opportunity for self-sovereignty of users’ physical assets. In this paper, we propose a generic NFT architecture for Web3. The architecture supports the rapid development of the upper application environment and automated value mapping of the underlying physical asset environment. To connect these two environments, a generic connecter has been designed to provide flexible storage for mapping data management, and to support universal cross-chain transactions. With these features, the values of heterogeneous physical assets can coexist in a unified Web3 world, and rich value transfer services can be developed on demand. This paper discusses the background of the proposed architecture, the open problems and our initial solution, as well as our design principles and advantages, and finally validates this novel NFT architecture. </p>

“…Where intra-chain denotes transactions within a single blockchain and cross-chain denotes transactions between users of heterogeneous blockchains. The results show that the maximum throughput of cross-chain is 727 transactions per second (tx/s) without the sharding scheme [13]. Intrachain transaction throughput is on average 1.2x that of crosschain as there is time-overhead for cross-chain transmission and verification.…”

<p>Non-Fungible Tokens (NFTs) do hold the promise of providing Web3 with the opportunity for self-sovereignty of users' physical assets. However, existing NFT marketplaces lack a generic design that allows the value of assets to flow efficiently. In this paper, we propose a generic NFT architecture for Web3. The architecture supports the rapid development of the upper application environment and automated value mapping of the underlying physical asset environment. To connect these two environments, a generic connecter has been designed to provide flexible storage for mapping data management, and to support universal cross-chain transactions. With these features, the values of heterogeneous physical assets can coexist in a unified Web3 world, and rich value transfer services can be developed on demand. This paper discusses the background of the proposed architecture, the open problems and our initial solution, as well as our design principles and advantages, and finally validates this novel NFT architecture.</p>

“…Tang et al designed a reputation-based consensus protocol (R-PBFT) using mixed reputation values, which improved transaction throughput and fault tolerance based on the PBFT algorithm [19]. Tang and Wang et al proposed an improved PBFT algorithm for blockchain high-frequency transaction scenarios (tPBFT), which optimized the pre-preparation and reply phases of the PBFT algorithm by introducing a trust-fair scoring mechanism [20].…”

This study proposes an improved Byzantine fault-tolerant consensus RB-BFT based on the reputation model to address the problems of low reliability of primary nodes and high communication complexity in the practical Byzantine algorithm (PBFT). First, this algorithm establishes a dynamic reputation model of nodes to distinguish honest and malicious nodes in the system, lowering the likelihood of malicious nodes being chosen as primary nodes and increasing the dependability of primary nodes. Second, the algorithm introduces supervisory nodes for information supervision while reducing the centrality of the system. Finally, this algorithm improves the consistency protocol of the PBFT algorithm by optimizing the process of mutual communication between nodes in the preparation and commitment phases, which reduces the algorithm communication complexity from O(n2) to O(n). Theoretical and practical studies reveal that the RB-BFT algorithm enhances performance and reliability greatly.
