App-Chains and Rollups

Architecture

App-Chains and Rollups represent distinct scaling solutions for blockchain networks, addressing limitations in transaction throughput and cost. App-Chains, functioning as application-specific blockchains, offer sovereignty and customization, enabling tailored consensus mechanisms and data structures optimized for particular use cases, such as decentralized finance or gaming. Rollups, conversely, execute transactions off-chain while leveraging the security of a Layer-1 blockchain, typically Ethereum, through data availability and fraud proofs or validity proofs. The selection between these approaches hinges on the trade-off between decentralization, scalability, and the complexity of implementation, impacting the overall system design and operational parameters.
