“…Complementary to the message transmission network built by the Internet, blockchain plays the critical role of value transmission network atop the widely used Internet. Until now, the advancement of blockchain has mainly experienced three stages [2], i.e., stage 1.0 initialized with cryptocurrency is represented by Bitcoin [3,4], stage 2.0 in the financial domain is represented by Ethereum [5], which supports Turing-complete programming languages to execute pre-agreed logic via smart contract, the ongoing stage 3.0 refers to various application fields including decentralized finance (Defi) [6], Internet of Things (IoT) [7], cyber security [8], content delivery networks [9], healthcare [10], smart city [11], metaverse [12], etc., which meet diversified and more complex real-world demands. With the blueprint and the gradual stepping into web3.0 [13] where data with semantic meanings are interconnected in a decentralized manner, blockchain sustainably shows its great potential in reshaping trust amongst individuals, and therefore, it is worth retrospectively investigating its core functionalities and primary applications.…”

Blockchain is a revolutionary technology that has reshaped the trust model among mutually distrustful peers in a distributed network. While blockchain is well-known for its initial usage in a public manner, such as the cryptocurrency of Bitcoin, consortium blockchain, which requires authentication of all involved participants, has also been widely adopted in various domains. Nevertheless, there is a lack of comprehensive study of consortium blockchain in terms of its architecture design, consensus mechanisms, comparative performance, etc. In this study, we aim to fill this gap by surveying the most popular consortium blockchain platforms and assessing their core designs in a layered fashion. Particularly, Byzantine fault tolerant (BFT) state machine replication (SMR) is introduced to act as a basic computational model of consortium blockchain. Then the consortium blockchain is split into the hardware layer, layer-0 (network layer), layer-I (data layer, consensus layer and contract layer), layer-II protocols, and application layer. Each layer is presented with closely related discussion and analysis. Furthermore, with the extraction of the core functionalities, i.e., robust storage and guaranteed execution, that a consortium blockchain can provide, several typical consortium blockchain-empowered decentralized application scenarios are introduced. With these thorough studies and analyses, this work aims to systematize the knowledge dispersed in the consortium blockchain, highlight the unsolved challenges, and also indicate the propitious avenues of future work.
