They contain information about the service, such as target performance level or monthly availability, and penalties for the violations of the SLA. The information about the penalties is essential because if the SP does not deliver what...
Conference Paper
The blockchain (BC) world is rapidly becoming a universe of several ledgers designed for a specific purpose, holding data previously stored (i.e., siloed) in centralized databases. The use of different BCs for the same purpose could hamper the frictionless exchange of data or value. On one hand, it is natural that there are competing implementation...
Chapter
Although the first Blockchain (BC) was proposed about a decade ago, BC achievements from a technical and functional perspective are measurable, but still face open issues. Since IFIP’s Working Group 6.6 on the “Management of Networks and Distributed System” investigated BCs in various aspects, this contribution here summarizes and clarifies key cha...
Article
As the number of blockchain (BC) platforms providing specific features increases, selecting a platform that fits all requirements needed for a specific case becomes a cumbersome task.
