Rollup Connectivity

Definition ∞ Rollup connectivity describes the ability of a rollup scaling solution to interact with other blockchain networks or layers. Rollups are layer-2 protocols designed to increase the transaction throughput of a base blockchain by processing transactions off-chain and then posting a summary back to the mainnet. Connectivity refers to their capacity to exchange assets or data with the underlying layer-1 chain, other rollups, or even external blockchains. Effective connectivity is vital for maintaining liquidity and composability across the broader blockchain ecosystem.
Context ∞ Rollup connectivity is a prominent topic in discussions about blockchain scalability and the future architecture of decentralized networks. News frequently covers advancements in interoperability solutions that enable seamless asset transfers between different rollups and the main Ethereum chain. The ongoing development of robust and secure connectivity mechanisms is crucial for the adoption of layer-2 scaling technologies and the expansion of the digital asset landscape.
