This paper investigated how the technology behind many of the cryptocurrencies and the Bitcoin is Blockchain Technology. Bitcoin Blockchain was the first blockchain technology in 2008 to provide as the public digital payment with no other third party or the middleman interface. The result showed that technology replaced the cash exchange method (i.e., Cryptocurrency, Digital Assets, and Distributed Ledger). Furthermore, the key main characteristics of blockchain and their potentials to technology (e.g., Decentralization, Immutability, Transparency, Persistency, Auditability, Security, and Privacy). Most of the application was built by using Blockchain Technology. Blockchain-as-a-Service (BAAS) for the enterprise (e.g., Ethereum, Cloud Storage, Supply Chain Communication, smart contract and E-Voting System). In this paper, we developed a democracy E-Voting System, that replaces the ancient mode of voting system. We tested and implemented our E-Voting system that runs with a smart contract by using the E-Wallets. After the voting is confirmed, it holds all the data of voters, ballots and transaction data. Performance analysis of the E-Voting System is theoretical and practical implications of the result are discussed.
