Storage Proofs

Storage proofs are cryptographic methods that allow a user to prove the existence of specific data within a blockchain state without requiring the full state history. These proofs use Merkle trees or other authenticated data structures to verify that a piece of information belongs to a particular block.

They are essential for cross-chain communication, where one blockchain needs to verify the state of another. By using storage proofs, protocols can avoid the need for trusted third-party oracles, relying instead on the consensus of the underlying blockchain.

This enhances the security and trustlessness of decentralized finance applications. They are a core component of interoperability solutions.
