Abstract: The advancement of blockchain innovation has prompted the making of decentralized applications (DApps), which permit client collaboration without the utilization of mediators. One of the most generally used blockchain stages for making DApps is Ethereum, which conducts business utilizing its own cash, Ether. Using Metamask, React.js, Node.js, and Solidity, we demonstrate the design and implementation of a decentralised system for Ethereum transfer in this paper. Our technology allows users to safely move Ether between accounts without the usage of intermediaries. We use React.js and

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

Abstract: Charity is an act of kindness, wherein a person who has financially more than enough of what he needs contributes part of his surplus earnings for the fulfillment of the needs of folks who are much less capable. The charity organizations lack transparency and the supervision of them is difficult to achieve, which has a negative impact on the willingness of the people to donate. Blockchain as an underlying technology provides a new solution for the charity system in terms of technology. This project proposed a charity system (D-Donation) based on blockchain technology and expounds the

A user-friendly program called “Mini Wallet for Sending Ethers” was created to make utilizing private keys to send ethers (ETH) between wallets easier. This application, which prioritizes user-friendliness, enables users to connect to their Ethereum wallets—including well-known choices like MetaMask— via the Infura API. It enables customers to effectively manage their Ethereum transactions by reducing crypto currency transactions to a few clicks, doing away with a requirement to browse complicated wallet interfaces. Notably, the program guarantees the security and integrity of transactions by
