Abstract

As a core technology that triggers a wave of disruptive revolution, the application of blockchain technology in the financial sector will potentially change the conventional transaction process and record-keeping methods, and thus significantly reducing costs and improving efficiency. Due to blockchain’s security, transparency, and non-tampering characteristics, the trust model between financial systems will no longer rely on intermediaries, and many businesses will be “decentralized” to realize real-time digital transactions. Ethereum is the well-known Turing-complete open-source blockchain platform where all computable logic operations can be implemented based on Ethereum smart contracts. Numerous innovative blockchain applications and innovative products of startups are growing up on it. The previous chapters have reviewed the core principles and development practices of Ethereum in detail. This chapter will concentrate more on the actual procedure by introducing two Ethereum-based practical applications: generic points system and electronic coupon system. The generic points system develops DApp applications directly on the underlying platform of Ethereum and calls the methods of smart contracts through the web3.js interface provided by Ethereum to send transactions or read data and display them to users on web pages, while the electronic coupon system, the overall architecture of which is a Java Web Project with the SSM framework, introduces blockchain technology at the application layer, independently encapsulates the interface tools for interaction with the Ethereum platform, uses the platform and the database to cooperate and store data, and develops smart contracts to record the actual backend business logic as transactions on the blockchain.
