Stateless Client Security

Definition

Stateless client security refers to the cryptographic and architectural measures implemented to ensure the safe and verifiable operation of light clients or nodes that do not store the entire blockchain state. These clients rely on proofs, such as Merkle proofs or zero-knowledge proofs, to verify the validity of transactions and state changes without needing full historical data. This approach reduces the data burden on individual users while maintaining a high level of security. It is crucial for enhancing accessibility.
