“…Only a few countries use the digital technology to calculate and manage VAT. By combining Decentralized Storage Network (DSN) with Smart Compact (SC), a new model is offered based on blockchain technology for authentication of the transaction, calculate and approve VAT [17]. Embedded secure bitcoin payment module is designed to realize the automatic payment.…”

In the presentage, online paymentsystem is a very simple practice.But manypeople use this system to manipulate people’s money. Many are trying for finding a variety of solutions. Butthereis no way to stopthatcrime.Blockchain’syoke is a blessing.Usingblockchainisaveryeasywaytocompletea paymentwithoutmakingany mistakes.Hackerwill never find a way to do theirworkin this kindof system. OurSystem is full workedwith Blockchain.Basically, we choose blockchainas our projectbecauseit is the most secureway to do a transaction in everyonlinesystem.Thecentralbusinessmodelis basedon a database management system. Once accomplishedthe security of the transaction can no longer be guaranteed. On the otherhand, itis really expensivetoresolvepossiblefraudtransactionsby a middle man.Aiming at solving issues concerningsecurityand worthlessness,there is a proposalof a model which is completely madeofblockchainsystem.InOursystemtherearemany blocksof information of eachandeverytransaction. Wehave proposedan algorithm.The algorithm will make consumersable to transact through cryptocurrency in blockchainnetworks.It is totally different from the fiat system where consumers will be able to transact without the help of thirdpartiesand vendors can also be relievedwith theirtransaction. Thistypeof transaction will be very comfortablefor both consumersand vendors. Consumers along with vendorscan see the whole transaction date, time and everythingthatthey dealtwith when the transaction was held.

The transactional information from the mobile wallets is offloaded from the mobile device to the mobile transaction server. The transaction involves various communication standards, confidential transaction information to ensure flawless transaction of data. There exist several encryption techniques to preserve confidentiality, hashing schemes to prove the integrity, signature schemes to prove the identity in the mobile transaction using mobile wallet applications. Even though mobile wallet possesses secure algorithms, the transactions are facing security issues such as double spending, lack of dispute redressal issue, lack of forward secrecy, lack of anonymity in the transaction and security. Therefore, Blockchain based Mobile transaction Scheme is proposed to solve the security issues including integrity, double spending and improve scalability. This paper presents a strategy which implements blockchain framework by using irreversible keys for mobile wallet applications. The proposed scheme proves to be secure against the security attacks and enhances integrity and scalability compared to the existing schemes.

“…Remix provides the functions of content management, smart contract compiler, input and output, and relative parameter setting. In addition, Remix could perform the testing, debugging, and deploying of the DApp on the browser (Nguyen, 2019). Moreover, Remix is a powerful compiler and is integrated with Solidity as the execution environment, which is primarily used in building smart contracts and supports both online and offline development.…”

Ballots are often hold for fair decisions such as party theme selecting, however, the existing traditional ballot has some problems involving amount of human resources, cost of places, equipment, time and traffic, and repeated procedures. In order to solve the issues aforementioned, a ballot blockchain system is designed and implemented based on the smart contract of Ethereum. It is designed on the core blockchain technologies of the decentralized ledger technology, using a secure hash algorithm, anonymous user, incorruptible data, and adopting a public blockchain. The ballot blockchain system is implemented based on the MetaMask verification and the Remix interface development environment. The smart contract plays the role of the decision-maker for controlling ballot activities instead of numerous human tasks. All ballot transactions are recorded in the ballot blockchain permanently when the ballot completed. The aim of the ballot blockchain system is to achieve a fair, less time-consuming, secured, and transparent environment.
