State Management
As a sovereign rollup, ABC Stack's state management differs fundamentally from traditional L2s. While L2s must commit state roots to Ethereum for settlement purposes, ABC Stack chains maintain and validate their state independently, posting only transaction data to Celestia.
The key aspects of this state management approach are:
Independent State Validation: Full nodes validate and maintain the complete state of the chain without requiring external settlement verification. Sovereign rollups handle their own state transitions.
Data Availability: Rather than settling state on Ethereum, ABC Stack relies on Celestia's data availability layer to ensure transaction data remains permanently accessible. This provides the foundational security guarantee for state validation, as Celestia ensures all nodes can access the data needed to verify and reconstruct the chain's state.
Optional Modular Bridge Architecture: State can be verified by external bridges if needed, but this is decoupled from core state management. Developers can pick whatever bridge they want without constraining the chain's state management.
