Layer 2 Composability Challenges

Architecture

Layer 2 composability challenges stem from the inherent design differences between various scaling solutions built atop base layer blockchains. These solutions, such as rollups (optimistic and ZK), sidechains, and validiums, often employ distinct data availability, execution, and settlement mechanisms. Consequently, seamless interaction and data sharing between these Layer 2 environments proves difficult, hindering the development of cross-rollup applications and limiting overall ecosystem efficiency. Addressing these architectural disparities requires standardized interfaces and protocols to facilitate interoperability and unlock the full potential of Layer 2 scaling.
