Polygon (MATIC) zkEVM Mainnet Beta to Launch cdk-erigon Sequencer with Eggfruit Upgrade
Polygon (MATIC) zkEVM Mainnet Beta is preparing for a major technical advancement with the launch of the cdk-erigon sequencer as part of the Eggfruit upgrade. This development promises to significantly enhance the performance and stability of the network, as reported by polygon.technology.
Key Features of the Eggfruit Upgrade
The Eggfruit upgrade, which is currently live on the testnet as of September 20, 2024, will transition to the mainnet following a 10-day timelock, concluding on September 30. This upgrade introduces several key improvements for developers:
- Increased Transactions Per Second (TPS): The new sequencer, developed by Gateway, the team behind the Ethereum Erigon client, is optimized for better transaction ordering, resulting in a more stable and higher-throughput network.
- Enhanced Stability: The upgrade aims to bring more stability to the Polygon zkEVM, allowing it to handle large volumes of traffic efficiently, similar to the Polygon PoS network.
- Double the zkCounters: The increase in zkCounters will enable more complex transactions, enhancing the network's computational capabilities.
- Deprecation of Legacy RPC Node: Following the upgrade, all infrastructure providers will need to adopt the cdk-erigon RPC Node, replacing the legacy RPC Node.
Upgrade Timeline and Maintenance
The Eggfruit upgrade is scheduled to go live on the mainnet beta on September 30 at 10:30 AM UTC. The maintenance period is expected to last approximately two hours, during which the Polygon zkEVM Mainnet Beta will experience downtime.
Developers are advised to verify the upgrade due to its impact on the PolygonZkEVM.sol consensus contract. The timelock is intended for the security and protection of all developers and users, aligning with the network’s governance model.
Verification and Preparation
Developers can independently verify the source code on GitHub to ensure it matches the deployed code on the network. Detailed instructions for verification are available on the Polygon documentation site.
Impact on Polygon CDK and Infrastructure Providers
The Eggfruit upgrade is not limited to the Polygon zkEVM Mainnet Beta. It also affects chains built with Polygon CDK, providing a significant boost in synchronization speed, up to 150 times faster.
Infrastructure providers will need to update to the latest versions once the upgrade is live on the mainnet. Preparations can begin with cdk-erigon v1.2.18, with specific version numbers to be shared closer to the upgrade date.
Actions Required for dApps
Existing dApps on Polygon zkEVM do not need to take any action when the upgrade goes live. However, developers are encouraged to use the Cardona testnet in the next ten days to observe how the upgrade improves network performance.
The Eggfruit upgrade marks a significant step forward for Polygon zkEVM, promising a more performant and stable future for the network.
