Definition ∞ State Commitments are cryptographic assurances that a specific state of a system, such as a blockchain ledger, has been recorded at a particular point in time. These commitments allow for efficient verification of data without needing to store the entire dataset. They are foundational for technologies like Merkle trees and other data structures.
Context ∞ State commitments are fundamental to the integrity and efficiency of many blockchain protocols, particularly in scaling solutions like rollups and sharding. They enable light clients to verify transactions and network state without downloading the full blockchain. Ongoing research aims to improve the efficiency and security of these cryptographic commitments.
