#blockchain Blockchain Scalability Challenges
Scalability is one of the most complex challenges in blockchain design.
As networks grow, they must process more transactions without sacrificing security or decentralization.
This is known as the Blockchain Trilemma:
Security
Decentralization
Scalability
Improving one often impacts the others.
That’s why scaling solutions are layered, modular, and continuously evolving.
Understanding scalability helps explain why no blockchain is “perfect” — only optimized for different goals.
