Scalability 

Commonly used in financial services and data science, the ability to increase in size. In crypto, this refers to a blockchain network’s ability to process more transactions per second without sacrificing network security. Initial iterations of Bitcoin and Ethereum were not optimized for scalability, hence why currently Ethereum processes 15-20 tps and Bitcoin only 7 tps! However, recent years of increased network demand and transaction volume has demonstrated a need for scalable solutions to further avoid bottlenecking user transactions or creating exorbitant transaction fees on the network.
