# Ethereum The Ethereum Mainnet consists of two interconnected layers: the Execution Layer and the Consensus Layer (Beacon Chain). This separation enables verification of execution-layer data through consensus-layer proofs. Every proof generated for Ethereum includes, at minimum, the BeaconBlockHeader and its BLS aggregate signature from the Beacon Chain, ensuring the consensus validity of the referenced execution block. Depending on the requested data, additional Merkle proofs from both the Beacon Chain and the Execution Layer are appended. These proof structures are designed to enable full verification of data accessible through common Ethereum [RPC-methods](https://github.com/corpus-core/colibri-stateless-doc/blob/main/specification/specifications/ethereum/ethereum/supported-rpc-methods.md). Supported proof types include: * StateRoot Proof * Storage Proof * Receipt Proof * Logs Proof * Transaction Proof * Account Proof * Code Proof * Sync Proof Together, these proofs establish a framework for stateless, verifiable access to all critical Ethereum state components without reliance on trusted RPC endpoints. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://corpus-core.gitbook.io/specification-colibri-stateless/specifications/ethereum.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
