The possibilities for expanding a digital currency and a crypto network are called scaling or scalability. This is not just about the growth potential of the network, but also about the system capacities as the security of a blockchain and comparable crypto networks.
Scalability is a fundamental component of the Blockchain Trilemma. In a Blockchain, the points decentralization, security and scalability are always in conflict, but all are important. The more scalable a blockchain is, the more centralized it usually is.
