Network Extensions

Definition ∞ Network extensions refer to auxiliary components or protocols that augment the functionality or capacity of an existing blockchain network. These extensions can include layer-2 scaling solutions, sidechains, or specialized modules designed to introduce new features or improve performance. By adding network extensions, blockchains can enhance their utility and address limitations inherent in their core architecture.
Context ∞ The development and adoption of network extensions are critical for the scalability and interoperability of blockchain technology. Solutions like optimistic rollups and zero-knowledge rollups are being implemented to increase transaction throughput and reduce fees, thereby broadening the accessibility of decentralized applications. The security and decentralization implications of various network extensions are subjects of ongoing technical and community deliberation.
