Scalability Constraints

Definition ∞ Scalability constraints refer to limitations in a blockchain network’s ability to process a large number of transactions quickly and efficiently. These constraints often lead to high transaction fees and slow confirmation times during periods of heavy network usage. They represent a significant barrier to widespread adoption of decentralized applications. Overcoming these limits is a primary focus for blockchain development.
Context ∞ News frequently reports on scalability constraints as a central challenge for major blockchain networks, impacting user experience and development. Debates often focus on various proposed solutions, such as Layer 2 protocols, sharding, or different consensus mechanisms. The ongoing pursuit of greater scalability is essential for blockchain technology to support global demand.
