Root Chain Anchoring

Root chain anchoring is the process of periodically committing the state or transaction hashes of a child chain to the main blockchain. This provides a permanent, immutable record of the child chain's progress and ensures that the main chain acts as the final source of truth.

By anchoring, the child chain inherits the security and decentralization of the root. This is a critical step for maintaining the integrity of the scaling solution.

It allows for cross-chain interoperability and enables users to verify the history of the child chain independently. The frequency of anchoring is a trade-off between performance and security.

More frequent anchoring increases security but also raises costs. Efficient anchoring strategies are vital for minimizing the overhead on the main chain while maximizing the protection of the secondary chain.

It is the fundamental bridge that connects the layers.
