Blockchain is a distributed digital ledger that stores any data and can record data about the transaction of cryptocurrency and Non-Fungible Token (NFT) ownership.Recently, cryptocurrency has become the most commonly used blockchain, it provides the potential to help a large wide range of applications.People prefer online transactions for speed, convenience, and the ability to generate financial activities from anywhere while also benefiting from features such as increased security measures and digital record-keeping.In the blockchain, hashing generates the network for transactions.However, due to unexpected conditions or external attacks, transaction failures can occur and require high security.This research proposes the Edwards-curve Digital Signature Algorithm (EdDSA) based on the Proof of Work (PoW) consensus algorithm for mobile payment transfer to provide effective transaction and security.In the verification phase, the receivers utilize the sender's public key and the received signature to verify the message using the PoW approach.When compared to existing approaches like Robust Payment Routing with an Approximation Guarantee (RobustPay+) and Multiple Charges Payment Channel Network based on Routing Protocol (MPCN-RP), EdDSA-PoW achieves a better success ratio of 1.2 in 50 nodes and success ratio and fee of 0.96 and 0.10 in 200 nodes.The proposed method achieves better values of 1.5 in Average maximum fee and 39 in Average accepted payment in 50 nodes compared to existing methods like e-commerce payment, RobustPay+, and Cryptocurrency Transactionbased Graph Convolutional Network (CTGAN).
The emergence of Non-Fungible Tokens (NFTs) has revolutionized the landscape of digital art, providing artists with new avenues for creation, distribution, and monetization. This research investigates the landscape of NFT art collections featuring Asian characters, specifically Japanese kanji and Korean hangeul, on the OpenSea platform. Theoretical frameworks drawn from digital art valuation, cultural representation in art, and blockchain technology guide the analysis. Findings reveal diverse manifestations of cultural identity and artistic innovation within the analyzed collections, reflecting the intersection of tradition and modernity in Asian art. Economically, prominent artists command substantial sales volumes, while others experience more modest transactions, underscoring the growing interest in NFT art within the global market. Culturally, NFT art collections serve as platforms for preserving and promoting traditional scripts and symbols, contributing to the global dissemination of Asian cultural heritage. Technologically, the adoption of blockchain technology empowers artists to assert ownership over their creations and establish new paradigms of value and authenticity. In conclusion, this research highlights the transformative potential of NFTs in reshaping the landscape of art and culture, emphasizing the need for continued exploration and collaboration to amplify cultural voices and expand artistic horizons in the digital age.
It is observed that there are several artists who are developing marvelous products but their product needs international exposure. These artists have limited market if they are going to promote and sell product. Moreover the there is lack of premium customer in rural areas. Thus artist who lives in rural area does not get proper incentive and significance. NFT is the only way to provide such artist global market where such artists may promote their art work. With the advent of blockchain technology NFT creation and marketing has been increased. Thus there are several international; market place such as Opensea and Young parrot that allows creation of NFT over Matic, Satoshi core, Ethereum and BNB smart chain. 9NFTMANIA proposed a lifestyle that is named as NFT culture. In these culture greetings, invitations, certificates, membership card would be made in form of NFT. In this way secure transfer of digital asset could be made and this NFT would have particular value. Even if a person wants to thank someone or want to say good morning then he should transfer NFT to other person's wallet. Moreover the supply of such greeting NFT would be limited thus there remains expectation of raise in price. On other hand holder of NFT would be able to access premium web services when web 3.0 mechanisms are applied to verify NFT holder in Metaverse.

The study aims to solve the problems in auditing ciphertext data, improve audit efficiency, and increase the security of audit data in the audit server. First, the existing encryption algorithms are analyzed. Second, the searchable encryption algorithm is proposed to audit the ciphertext data, and an audit server scheme is made based on blockchain technology (BT). Finally, the two schemes are compared with the traditional audit technology. The results show that the server's inspection efficiency of the searchable encryption algorithm is higher.
Blockchain is a distributed ledger that combines technologies such as cryptography, consensus mechanism, peer-to-peer transmission, and time stamping. The rapid development of blockchain has attracted attention from all walks of life, but storage scalability issues have hindered the application of blockchain. In this paper, a scalable blockchain storage model based on Distributed Hash Table (DHT) and the InterPlanetary File System (IPFS) was proposed. This paper introduces the current research status of the scalable blockchain storage model, as well as the basic principles of DHT and the InterPlanetary File System. The model construction and workflow are explained in detail. At the same time, the DHT network construction mechanism, block heat identification mechanism, new node initialization mechanism, and block data read and write mechanism in the model are described in detail. Experimental results show that this model can reduce the storage burden of nodes, and at the same time, the blockchain network can accommodate more local blocks under the same block height.
To ensure the security of data transmission and recording in Internet environment monitoring systems, this paper proposes a study of a secure method of blockchain data transfer based on homomorphic encryption. Blockchain data transmission is realized through homomorphic encryption. Homomorphic encryption can not only encrypt the original data, but also ensure that the data result after decrypting the data is the same as the original data. The asymmetric encrypted public key is collected by Internet of things (IoT) equipment to realize the design of blockchain data secure transmission method based on homomorphic encryption. The experimental results show that the accuracy of the first transmission is as high as 88% when using the transmission method in this paper. After several experiments, the transmission accuracy is high by using the design method in this paper. In the last test, the transmission accuracy is still 88%, and the data transmission effect is relatively stable. At the same time, compared to the management method used in this article, the transfer method used in this paper is more reliable than the original transfer method and is not prone to data distortion. It can be seen that this method has high transmission accuracy and short transmission time, which effectively avoids the data tampering caused by too long time in the transmission process.
