In modular blockchain architectures, the interface protocol between the execution layer and the data availability layer faces several version compatibility pitfalls. Backward incompatibility occurs when new protocol versions change data formats, blocking older execution layers from interacting with updated data availability layers. Security vulnerabilities linger if one layer isn’t updated, exposing the system to known attacks despite partial upgrades. Performance degradation emerges when mismatched versions fail to leverage new optimizations, reducing efficiency. Additionally, uncoordinated updates can destabilize the system, causing transaction errors. Effective version management and synchronized updates are critical to ensure seamless communication and maintain system reliability.
