ABSTRACT
The participants in the blockchain network have some roles and responsibilities that require an attentive governance structure for achieving an efficient balance of security and access. So, on a broader scale, there are two types of blockchain: permissioned and public blockchains. Businesses are attracted by the in-built security protection features that blockchain networks offer, and are keener to migrate existing systems to blockchain-based solutions to improve their security. The distributed structure of a blockchain system favours business continuity and in-built security in the network itself by removing single points of failure. When considering the protection of data and source code stored in the blockchain, critically the blockchain network topology must be considered. Blockchain systems provide in-built features to reduce cybersecurity risks and to avoid cyber-attacks. The blockchain network has distributed topology which provides resistance to cyber-attacks and business consistency.
