The Merge was Successful

Ethereum successfully migrated from Proof of Work (PoW) to Proof of Stake (PoS) on September 15th. Better understand the impact of the Merge and how QuickNode is supporting Ethereum going forward.

June 8th

Ropsten merges to Proof of Stake (PoS)

August 11th

Goerli merges to Proof of Stake (PoS)

August 29th

Addition of Ethereum Mainnet Beacon APIs

September 6th

Bellatrix Hardfork

September 15th

Mainnet successfully merged

Q4

Decommission Ropsten, Kovan, and Rinkeby

Impact on testnets
Goerli
Recommended
This is the best long-term testnet for Ethereum.
Sepolia
Supporting in Q4
We will be adding support for Sepolia in the near future. In the meantime, please move your testing to Goerli.
Ropsten
Decommissioning Q4
Official Ropsten support has been deprecated by the Ethereum Foundation. QuickNode will be decommissioning support for Ropsten in Q4. Please move your testing to Goerli.
Kovan
Decommissioning Q4
Official Kovan support has been deprecated by the Ethereum Foundation. QuickNode will be decommissioning support for Kovan in Q4. Please move your testing to Goerli.
Rinkeby
Decommissioning Q4
Official Rinkeby support will be deprecated by the Ethereum Foundation. QuickNode will be decommissioning support for Rinkeby in Q4. Please move your testing to Goerli.

What is The Merge?

The Merge is the transition of Ethereum from Proof of Work (PoW) to Proof of Stake (PoS).

The transition to POS will remove the need for energy-intensive mining process while also securing the network using staked ETH. This transition will lay the foundation for better security, scalability, and sustainability.

For more detail, you can go to the Ethereum Foundation.

How is QuickNode handling The Merge?

Methods
We added support for Ethereum Mainnet Beacon REST APIs. You can already see the methods available in our docs, they start with eth/.

Read docs
Testnets
We have outlined the impacts to testnets above, where we will continue to support Goerli in the long-term. The other testnets (Ropsten, Kovan, and Rinkeby) will be decommissioned in Q4.
Client
We are using Lighthouse as our client. In our internal testing, we found that Lighthouse provided the most consistent REST API performance across a wide variety of methods. In case of failure, we have Teku as a backup. We will continue to run Geth, Nethermind, Erigon nodes.

How will this affect the JSON-RPC responses from QuickNode?

The Merge will happen between blocks and all current JSON-RPC methods will behave in nearly identical ways, with only slight modifications to the parameters returned.

If you would like to know more about these changes, we recommend reading the official Ethereum Foundation blog post here: https://blog.ethereum.org/2021/11/29/how-the-merge-impacts-app-layer/.
