Distributed Ledger and Blockchain Security

What is distributed ledger technology?

Distributed Ledger Technologies (DLT), such as blockchain, are transforming industries worldwide by delivering total transparency across the global business network. A wide range of industries - from finance and insurance to medical and publishing companies, as well as government agencies – are using DLT to build decentralised transaction structures, which facilitate new business models and improve efficiency. While the transformative potential of DLT seems endless, it also represents multiple security vulnerabilities that must be addressed. Consequently, the success of the business ecosystem depends on its secure installation, configuration and use.

Why is distributed ledger and blockchain security important?

As DLT is collectively operated between the participants of a decentralised network, software which supports the specific use case must be developed to make it usable within this shared business framework. However, as with all newly developed software, after initial deployment and continuous functional extension, it can be failure prone. Flaws and errors in the design, programming and configuration are examples of typical sources for vulnerabilities throughout the life-cycle. Furthermore, unauthorised user practices for storage and sharing, as well as endpoint applications such as laptops and smartphones, also expose the network to security vulnerabilities.
