Resumé: In recent years, Blockchain technology has been widely attracted and used in many industrial sectors, including the healthcare sector, cryptocurrencies, artificial intelligence, the government sector and internet of things etc. Blockchain has unique features such as decentralization, transparency, provenance, fault tolerance, and authenticity that are used by many systems to deploy a wide range of distributed applications that are fully distributed peer-to-peer architecture that records digital assets (e.g., transactions). Despite these attractive characteristics, one of the key limitations of blockchain is scalability; indeed, the number of transactions that can be processed per second is small and insufficient. Furthermore, decentralization is the core and the nature of blockchain, security is an essential propriety, whereas scalability is the main challenge. The key challenge is to achieve scalability, security, and decentralization at the same time.The aim of the thesis is to find an optimal approach for a trade-off between scalability and security.
