Rollup Scaling

Definition ∞ Rollup scaling refers to a class of layer-two scaling solutions designed to increase transaction throughput on blockchains. Rollups bundle numerous transactions off-chain, generate a cryptographic proof of their validity, and then submit a compressed summary to the main blockchain. This method significantly reduces the cost and increases the speed of transactions.
Context ∞ The ongoing development and adoption of rollup technologies are a primary focus in the scaling debate for major blockchains like Ethereum. News regarding new rollup implementations, their interoperability, or their performance metrics is crucial for understanding the future capacity and cost structure of decentralized applications. The competitive landscape among different rollup designs also warrants attention.
