Transitioning from Goerli to Sepolia and the Upcoming Dencun Upgrade

Transitioning from Goerli to Sepolia and the Upcoming Dencun Upgrade

QuickNode is excited to help the Ethereum community transition from Goerli Testnet to the Sepolia Testnet. In tandem with the Ethereum Foundation, QuickNode will deprecate Goerli in Q1 2024, pivoting to Sepolia to offer enhanced scalability, lower gas fees, and a robust developer environment.

Key Differences Between Goerli and Sepolia

  1. Support and validation: Sepolia has ongoing support from the Ethereum Foundation and a more predictable network state due to its permissioned validator set.
  2. Network efficiency: Being newer, Sepolia offers quicker sync times and smaller storage requirements for running your own node.
  3. Token supply: Unlike Goerli, which faced token supply issues leading to test ETH gaining unintended value, Sepolia has an uncapped supply of ETH, addressing this issue effectively.

Transitioning from Goerli to Sepolia

For developers, the shift from Goerli to Sepolia is crucial. QuickNode provides easy tools to create a Sepolia endpoint and access ETH for testing. Sepolia’s streamlined and stable environment is conducive to efficient dApp development and testing.

The Dencun Upgrade

The Dencun network upgrade marks the end of Goerli as a supported Ethereum testnet. Following the Dencun activation, validator teams will gradually exit, affecting the network's stability. Developers and infrastructure providers are encouraged to migrate to Sepolia for a stable testing environment.

Dencun combines two upgrades: (1) Deneb, the name for the Consensus Layer upgrade, and (2) Cancun, the name of the Execution Layer upgrade. This upgrade will center around EIP-4844 and include a few other proposals.

For more information (along with the EIPs for the upgrade):

Highlights of Dencun:

  • EIP 4844 (proto-danksharding): Aims to scale Ethereum and lower fees for layer 2 rollups.
  • Testnet options: Sepolia for application testing, Holesky for protocol-level testing, and Ephemery for validator setup.
  • Additional technical upgrades: Include EIPs 6780, 6475, and 1153.
