“…Through smart contracts, each node in a data-exchange P2P network makes consensus and endorsements for each other, queries the transaction record and checks the payment bill from its local blockchain peer. Same as [100], there are also some other works [2,28,45,80] that use the storage of data on the blockchain and the use of smart contracts for secure cloud data sharing.…”

Blockchain has been widely deployed in various fields, such as finance, education, and public services. Blockchain has decentralized mechanisms with persistency and auditability and runs as an immutable distributed ledger, where transactions are jointly performed through cryptocurrency-based consensus algorithms by worldwide distributed nodes. There have been many survey papers reviewing the blockchain technologies from different perspectives, e.g., digital currencies, consensus algorithms, and smart contracts. However, none of them have focused on the blockchain data management systems. To fill in this gap, we have conducted a comprehensive survey on the data management systems, based on three typical types of blockchain, i.e., standard blockchain, hybrid blockchain, and DAG (Directed Acyclic Graph)-based blockchain. We categorize their data management mechanisms into three layers: blockchain architecture, blockchain data structure, and blockchain storage engine, where block architecture indicates how to record transactions on a distributed ledger, blockchain data structure refers to the internal structure of each block, and blockchain storage engine specifies the storage form of data on the blockchain system. For each layer, the works advancing the state-of-the-art are discussed together with technical challenges. Furthermore, we lay out several possible future research directions for the blockchain data management systems.

“…In [27], a lightweight proxy re-encryption scheme is proposed, which builds the pre-encryption algorithm and designs a certificateless protocol that remove bilinear pair and have very high performance. Qin et al [28] introduced Shamir secret sharing scheme and permissioned blockchain to eliminate the single point failure, and computed tokens cross domains to reduce communication and computation overhead on the data user side. Qin also made other work to realize access control based on different scenarios, such as [29,30].…”

The emerging of cloud data sharing can create great values, especially in multi-cloud environments. However, "data island" between different cloud service providers (CSPs) has drawn trust problem in data sharing, causing contradictions with the increasing sharing need of cloud data users. And how to ensure the data value for both data owner and data user before sharing, is another challenge limiting massive data sharing in the multi-cloud environments. To solve the problems above, we propose a Uniform Encoding and Parsing Framework (UEPF) with blockchain to support trustworthy and valuable data sharing. We design namespace-based unique identifier pair to support data description corresponding with data in multi-cloud, and build a blockchain-based data encoding protocol to manage the metadata with identifier pair in the blockchain ledger. To share data in multi-cloud, we build a data parsing protocol with smart contract to query and get the sharing cloud data efficiently. We also build identifier updating protocol to satisfy the dynamicity of data, and data check protocol to ensure the validity of data. Theoretical analysis and experiment results show that UEPF is pretty efficient.

“…As we all know, medical data contains a lot of high-definition pictures, videos and so on, so it needs a large amount of space for storage. Qin X. et al [16] encapsulated the patient's electronic record in the blockchain based on a multi-authoritative signature scheme to resist collusion attacks. However, the blockchain storage is limited, and too much data will slow down its performance.…”

A digital emergency rescue system is an effective means to achieve accurate rescue, minimize casualties and property losses. When large emergencies occur, medical institutions need to jointly participate in the emergency rescue coordination. But it is hard to share medical resource and injured information, which reduces the efficiency of recue and affects the treatment of injured person.Therefore, this paper proposes a rescue information sharing architecture based on blockchain and distributed storage, which shares data for many medical institutions. Moreover, we propose a new consensus algorithm ERBFT based on reputation models and Verifiable Random Function (VRF) to reduce communication complexity, and maintain the security of blockchain information sharing system.
