Relationship with GateChain

Division of Responsibilities​

  • Gate Layer (L2 Execution Layer):

    • EVM execution environment and Sequencer based on OP Stack;
    • Responsible for fast, low-cost transaction processing and application deployment;
    • Submits batches and state roots to GateChain through Batcher/Proposer;
    • Integrates LayerZero and other cross-chain protocols to provide interoperability capabilities.

  • GateChain (Settlement + Data Availability Layer):

    • Serves as the settlement and finality source, hosting Rollup contracts;
    • Provides Blobs to store batch data/state roots (reducing costs, ensuring verifiability);
    • Security and governance provided by GT staking and validator network;
    • Responsible for treasury/governance and other economic and management functions.

Security and Finality​

  • L2 transactions are quickly confirmed on Gate Layer; finality is determined by Rollup contract confirmation on GateChain.
  • GT Staking backed validator and consensus on GateChain provides settlement security and data availability guarantees.

Fees and Economic Flow​

Transaction fees on Gate Layer are designed as a sum of two components to accurately reflect the cost of execution on L2 and data storage on L1.

  • L2 Execution Fee:

    • This fee covers the computational resources required to execute a transaction in the Gate Layer EVM.
    • It follows the standard EIP-1559 model, consisting of a baseFee and a priorityFee. This portion is the primary revenue for the Sequencer.

  • L1 Data Fee:

    • This fee covers the cost of publishing transaction data as Blobs to GateChain (L1), ensuring data security and availability.

  • Fee Flow and Governance:

    • The total fee paid by the user (L2 Execution Fee + L1 Data Fee) is collected by the Sequencer.
    • The Sequencer then pays the cost to submit data to L1 (L1 Data Fee), retaining the remainder (L2 Execution Fee) as its operational profit.
    • In the future, governance can implement mechanisms to redistribute Sequencer revenue, for instance, by directing a portion to an ecosystem treasury or using it to incentivize network participants.

Cross-Chain Interoperability​

  • The application layer achieves multi-chain asset/message interoperability through LayerZero and ecosystem bridges;
  • The security anchor for interoperability is finality on GateChain: cross-chain releases/settlements are confirmed by L1.

Availability and Verifiability​

  • Transaction batches and state roots are persisted in GateChain's Blobs and Rollup related contracts;
  • Any party can reconstruct and verify L2 state based on L1 data, meeting verifiability and audit requirements.

Operations and Observability​

  • L2 provides RPC and WS interfaces, nodes, indexing services, and Explorer;
  • Contract addresses, network parameters, and bridge entry points are centrally provided in the documentation (Get Started / Developers).
