Shed Light

The global popularity of digital cryptocurrencies and research in a decentralized system have led to the foundation of blockchain, which is fundamentally a public digital ledger to share information in a trustworthy and secure way. The concept and applications of blockchain have now spread from cryptocurrencies to various other domains, including business process management, smart contracts, IoT, and so on. Cryptocurrency is a mechanism designed to work for the online secure payments system using cryptography. Cryptography maintains confidentiality, integrity, and authentication. Cryptocurrency has come as a novel way of making payments that keep all the transactions secure and safe, which avoids any type of intermediaries such as a bank. This chapter will shed light on the concept of blockchain technology, security, and its applications in various domains.

Process Execution

First come, first served: Critical choices between alternative actions are often made based on events external to an organization, and reacting promptly to their occurrence can be a major advantage over the competition. In Business Process Management (BPM), such deferred choices can be expressed in process models, and they are an important aspect of process engines. Blockchain-based process execution approaches are no exception to this, but are severely limited by the inherent properties of the platform: The isolated environment prevents direct access to external entities and data, and the non-continual runtime based entirely on atomic transactions impedes the monitoring and detection of events. In this paper we provide an in-depth examination of the semantics of deferred choice, and transfer them to environments such as the blockchain. We introduce and compare several oracle architectures able to satisfy certain requirements, and show that they can be implemented using state-of-the-art blockchain technology.
