“…A peer-to-peer (P2P) storage network, IPFS is a new kind of storage technology [23]. The IPFS [24,25] is a distributed file system that was created to address the issue of excessive file redundancy. Assigning a different hash value to each file, IPFS is a decentralized and shared storage technology to divide files into several pieces that are stored on each network node.…”

Transaction volumes are growing rapidly, demonstrating how well-liked online auctions are with shoppers. Bidders can access a wider variety of products and sellers can reach a larger audience through online auction platforms. However, privacy concerns have reduced users' trust in auction platforms, and difficult disputes have caused consumers to question the fairness of online auctions, negatively impacting the market growth. The emergence of blockchain technology has brought a new approach to solving these problems. Blockchain is a new generation of information technology that is decentralized, transparent, traceable, anti-tampering, and unforgeable, following big data, cloud computing, and artificial intelligence. In this paper, we present a blockchain-based online auction solution as well as an auction protocol that uses ring signatures to guarantee anonymity. Three features summarize this essay: (1) Making use of blockchain technology to ensure that the auction transaction process is transparent, traceable, tamper-proof, and unforgeable.(2) The ring signature-based anonymous auction protocol allows for the concealment of bidders' public keys in a group of public keys. Because malicious individuals are prevented from evaluating data by tracking numerous transactions of a single public key, this significantly protects the privacy of bidders. (3) The proposed scheme promotes auction fairness and effectively resolves disputes.

Digital assets backed up by blockchain technology are termed Non-Fungible Tokens (NFTs). Every NFT is uniquely identified by its metadata, stored in the smart contract. This metadata can consist of associated images, descriptions , attributes, and other relevant details in a JavaScript Object Notation (JSON) object. Most of these NFTs are static; therefore, their metadata remains immutable. Due to rising blockchain use cases like real-world token regulation and blockchain-based ticketing platforms, a need arises to modify the existing metadata and require interaction for community engagement. Here, Dynamic NFTs (DNFTs) bring the notion of adding upgradeability and interactivity to existing NFTs. We propose a DNFT generation system built on top of decentralized oracle networks and utilizing on-chain metadata using smart contracts, which could be used as a base for future dynamic NFT generation models. Furthermore , we are bringing the web2 equivalent experience to viewable content, which can be used for ad spaces and real-time messaging in the form of NFTs. Henceforth, we are augmenting NFTs for versatile use cases, such that they are more than just static assets.

“…Additionally, IPFS has limitations in terms of handling large files or high traffic volumes, which could impact its effectiveness for applications requiring quick and dependable access to vast amounts of data. The decentralized and distributed nature of IPFS, operating as a public P2P network, raises potential legal and regulatory concerns for the storage of confidential patient information [8,9].

<p>Recent technological advancements have led to the development of new methods for managing organ donation systems, which aim to overcome the limitations of traditional centralized systems. To achieve increased transparency, security, and efficiency in the organ donation process, blockchain technology is being proposed as a replacement for these centralized systems. However, most previous works on organ donation systems have focused on using Ethereum-based blockchain solutions, which offer limited control, a fixed set of consensus protocols, and no support for concurrent executions. In contrast, our work has utilized the Hyperledger Fabric framework to develop a network model of the organ donation system. We have designed and deployed a prototype system with smart contracts using Amazon Managed Blockchain Service. Additionally, we have built a client application that uses the Fabric SDK to interact with the network and perform various actions. To evaluate the performance of our system, we conducted extensive testing using the Hyperledger Caliper benchmarking tool. In our test bench, the system achieved a peak actual send rate of 389.1 transactions per second (TPS) for creating new records and 508.4 TPS for reading records. At a send rate of 800 TPS, the system took an average of 12.16 seconds to serve a request for creating a record and an average of 3.71 seconds to serve a request for reading a record. Future work is required to extend the functionalities of the system and identify potential endorsers and managers for this type of controlled blockchain network.</p>
