Blockchain Scalability: Addressing the Trilemma for Mass Adoption

Blockchain technology has shown immense potential in various industries, but one of its significant challenges is scalability. Blockchain scalability refers to the ability of a blockchain network to handle increased transaction volumes, accommodate growing user bases, and maintain high performance without sacrificing security and decentralization. Overcoming scalability limitations is crucial for achieving widespread blockchain adoption and realizing its full potential.

Understanding Blockchain Scalability

Blockchain scalability refers to the capacity of a blockchain network to process a larger number of transactions per second (TPS), store a larger volume of data, and handle increased network activity. It involves optimizing the underlying protocols, consensus mechanisms, and infrastructure to ensure efficient performance as the network grows.
