Blockchain systems (more precisely Distributed Ledger Technologies(DLTs)) represent a different digital ecosystem compared with traditional computer systems. One major difference are the performance and scalability factors which will be discussed and analytically investigated in this paper. Indoing so, we provide guidance for defining a research agenda focusing on the investigation of the crucial role of scalability for DLT systems. System performance - measured in terms of (1) consensus response time (blockchain network latency or time to convergence/agreement); (2) number of transactionsper second or throughput, and (3) computing (and power) resources consumed - can be understood by considering the design dimensions of a DLT system, namely: (i) the type of DLT system needed from a requirements perspectivewhich in turn determines; (ii) the complexity of the consensus protocol used; (iii) the topography of the anticipated traffic flow on the network; (iv) the performance and complexity of the domain-specific language that implementssmart contracts; and (v) by the anticipated growth in size and complexity of the distributed ledger itself.Blockchain systems (more precisely Distributed Ledger Technologies(DLTs)) represent a different digital ecosystem compared with traditional computer systems.
