# System Architecture Overview

IBVM operates as a layered stack composed of the following major components:

1. Bitcoin Base Layer: The foundation that provides security and final settlement
2. Bridge Protocol: Manages the secure movement of BTC between the base layer and IBVM
3. Execution Layer: EVM-compatible environment for transaction processing
4. Sequencer Network: Orders and processes transactions before settlement
5. Prover System: Generates ZK-SNARKs to validate state transitions
6. Data Availability Layer: Ensures transaction data remains accessible

Settlement Layer: Submits compressed proofs to the Bitcoin blockchain
