The COTI network is comprised of several core components:

  1. Full Nodes: These nodes are responsible for validating transactions and ensuring the integrity of the COTI blockchain network. They act as the decentralized foundation of the network.

  2. Sequencer: This component processes transactions (TXs) and organizes them into blocks. It coordinates transaction flow and ensures orderly addition to the chain.

  3. Executors: Two separate executors that process blocks in a MPC manner:

    • Red Blocks: incoming blocks processed from the sequencer to the executors.

    • Black Blocks: outgoing blocks processed from the executor to the sequencer.

  4. GC Manager: Stores the generated garbled circuits in data warehouse, these circuits are used by the executors for on-chain computation.

  5. Garbler: Generates garbled circuits that are stored into the DB Manager to be used later on during on-chain computation.

The network uses a multi-tier architecture to optimize transaction flow and ensure scalability, with the sequencer bridging full nodes to the execution layer and the database manager and garbler handling persistence and post-processing.
