Introducing the Governor V2: Improving Transaction Efficiency with Wormhole
Wormhole, a leading interoperability platform, has introduced the Governor V2, a flow-canceling Governor mechanism designed to address congestion issues and enhance transaction efficiency across its supported blockchains. This new feature focuses on net flows to minimize delays and improve transaction throughput while maintaining security.
The Need for a Flow-Canceling Governor Mechanism
Wormhole’s existing rate-limiting mechanism, the Governor, sets a ceiling on the total USD-denominated outflow of a chain within a 24-hour period. However, as usage increases, many chains often reach their Governor limits, leading to delays and user dissatisfaction. This congestion is primarily caused by non-fraudulent activities such as arbitrage and settlement, which utilize Governor limits, reducing their effectiveness in risk mitigation.
Flow-Canceling Design
The flow-canceling Governor mechanism aims to tackle these challenges by considering both inflows and outflows. Here’s how it operates:
- Measuring net flow: The Governor now accounts for inflows along with outflows, reducing limit utilization when assets flow into a chain, effectively canceling out the outbound flows that initially increased it. Only net flows (the difference between inflows and outflows) will be restricted.
- Net flow handling: Transactions with zero net flow, like when users transfer a fixed amount of assets in and out of a chain, will no longer consume Governor limits under this new approach.
- Reputable assets: Initially available for a select group of stablecoins, the flow-canceling feature enables improved net flow management while maintaining security advantages.
Benefits of the Flow-Canceling Governor
This innovative mechanism offers several benefits:
- No delays for users when the net flow is below the Governor limit for a specific chain.
- Support for increased transaction flow in both directions without raising Governor limits.
- Maintaining lower limits by the protocol, reducing risks and enhancing vulnerability protection.
- Allows participants like Guardians, Contributors, and Builders to focus on developing interoperability solutions rather than managing Governor limits.
Backtesting Analysis
Wormhole carried out a mock implementation of the flow-canceling strategy against historical VAA flows, revealing significantly lower net flows compared to a simple outbound strategy. This indicates that the flow-canceling approach will reduce potential user delays. Moreover, stablecoins like USDC and USDT account for a significant portion of Governor limit utilization, showcasing the effectiveness of applying the flow-canceling mechanism to these tokens to handle a higher transaction volume.
Conclusion
The flow-canceling Governor mechanism presents a promising solution to congestion during periods of high utilization. By focusing on net flows, Wormhole can accommodate more transactions while upholding security and liveness objectives, thereby enhancing the cross-chain experience, reducing delays, and improving overall efficiency.
