“…In addition, the problem of index version control is considered for the first time, and two simple algorithms are developed to resolve this problem. In fact, delay has always been a thorny issue [32] in the p2p system. The experiments show that, when nodes are distributed in a local area network, the operation times of decentralized B+Tree and HashMap are acceptable.…”

The emerging decentralized storage systems (DSSs), such as InterPlanetary File System (IPFS), Storj, and Sia, provide people with a new storage model. Instead of being centrally managed, the data are sliced up and distributed across the nodes of the network. Furthermore, each data object is uniquely identified by a cryptographic hash (ObjectId) and can only be retrieved by ObjectId. Compared with the search functions provided by the existing centralized storage systems, the application scenarios of the DSSs are subject to certain restrictions. In this paper, we first apply decentralized B+Tree and HashMap to the DSSs to provide keyword search. Both indexes are kept in blocks. Since these blocks may be scattered on multiple nodes, we ensure that all operations involve as few blocks as possible to reduce network cost and response time. In addition, the version control and version merging algorithms are designed to effectively organize the indexes and facilitate data integration. The experimental results prove that our indexes have excellent availability and scalability.

“…The transfer was instant when the two peers exchanging the files were connected directly. Additionally, we reviewed a study on the IPFS performance [39], which shows that for our small file sizes, the scalability of the IPFS is sufficient. currently around 45 × 10 9 per day with peaks reaching 60 × 10 9 .…”

Freight exchanges are central to the logistics industry, as they reduce empty runs and meet spot demands. To improve their efficiency in terms of automation and enhance trust between the participants, we propose a decentralized freight exchange implemented using public blockchains. With our solution, we also address shortcomings of public blockchains, such as scalability and privacy. We present two artifacts: a general architecture for an electronic logistics marketplace (ELM) and a concrete implementation as the proof of concept for a freight exchange. The solution is implemented using two off-the-shelf public blockchains and a public distributed file system. Additionally, we investigate the implications for the general ELM model and show that an ELM based on a blockchain can be viewed as infrastructure rather than a market participant.

“…Recently, Shen et al [40] conducted the systematic evaluations of IPFS storage system by deploying real geographically-distributed instances on Amazon EC2 cloud. The authors emphasize on the data I/O operations from a client's perspective.…”

“…For example, Wennergren et al [39] mentioned that the limited bandwidth of each instance of IPFS could be one of the critical reasons for the low scalability of IPFS. The quantitative analysis [40] of systematic evaluations towards IPFS storage system indicates that downloading and resolving operations could be bottlenecks while IPFS clients are reading objects from remote nodes. Nyaletey et al [41] evaluated the scalability of the proposed BlockIPFS by varying the number of nodes.…”

Constructing globally distributed file systems (DFS) has received great attention. Traditional Peer-to-Peer (P2P) distributed file systems have inevitable drawbacks such as instability, lacking auditing and incentive mechanisms. Thus, Inter-Planetary File System (IPFS) and Swarm, as the representative DFSs which integrate with blockchain technologies, are proposed and becoming a new generation of distributed file systems. Although the blockchain-based DFSs successfully provide adequate incentives and security guarantees by exploiting the advantages of blockchain, a series of challenges, such as scalability and privacy issues, are also constraining the development of the new generation of DFSs. Mainly focusing on IPFS and Swarm, this paper conducts an overview of the rationale, layered structure and cutting-edge studies of the blockchain-based DFSs. Furthermore, we also identify their challenges, open issues and future directions. We anticipate that this survey can shed new light on the subsequent studies related to blockchain-based distributed file systems. INDEX TERMS Blockchain, distributed file systems, IPFS, swarm.
