Before diving into the details of Storage Proofs, it’s important to understand some key concepts:
  1. Storage Proofs: A fusion of inclusion proofs, which confirm data’s presence, and proofs of computation, which validate the execution of a multi-step workflow to attest the validity of one or multiple elements in a large dataset such as the whole Ethereum blockchain or a rollup.
  2. Block Hash: A unique identifier for a block, summarizing all its contents. It’s crucial for anchoring Storage Proofs to a specific point in blockchain history.
  3. Block Header: Contains metadata about a block, including important roots (state, receipts, transactions) used in the Storage Proof process.
  4. Merkle Trees: Data structures used in blockchains to efficiently and securely verify the contents of large data sets.
  5. Inclusion Proofs: Demonstrate that a specific piece of data is part of a larger data set (like a Merkle tree) without revealing the entire data set.
  6. Zero-Knowledge Proofs: Allow verification of information without revealing the underlying data, enhancing privacy and efficiency in blockchain systems.
  7. Turbo: A smart contract interface that simplifies the integration of Storage Proofs into applications, making cross-chain data access more accessible to developers.
  8. Historical Block Hash Accumulator: A system that allows smart contracts to access and verify historical block hashes efficiently.
  9. Facts Registry: A contract that stores and manages proven blockchain data, allowing other contracts to access this verified information.
  10. Cross-Chain Interoperability: The ability for different blockchain networks to communicate and share data securely, a key use case for Storage Proofs.
Understanding these concepts will provide a solid foundation as you explore the more detailed aspects of Storage Proofs and their applications in the following sections.
