Ethereum (ETH)’s Ropsten public testnet, which allows for blockchain development testing before deployment on the mainnet, is estimated to undergo “the Merge” on June 8 before the Ethereum blockchain can switch to proof-of-stake (PoS) consensus.
Ropsten Testnet Merge Set for June 8
According to the Merge testnets page on GitHub, Ethereum DevOps engineer Parathi Jayanathi submitted a pull request for the Ropsten testnet Merge configuration code on Monday, suggesting that the code is ready to be implemented.
The specific testnet is seen as the best replication of the Ethereum Mainnet as it follows a similar network structure, enabling developers to conduct realistic deployment testing before making updates to the actual mainnet.
The Merge will mean the end of proof-of-work mining on the Ethereum network to a more sustainable proof-of-stake model.
Merge Goes Through Two Steps
The Ropsten public testnet undergoes the merge in two steps. First, a genesis version of the consensus layer is created which is slated to happen on May 30. Following that, the Ropsten testnet goes through the merge.
“Merging Ropsten is a huge testing milestone towards Ethereum’s mainnet merge later this year,” said Preston Van Loon, an Ethereum core developer at Prysmatic Labs.
Another core developer said last week that the Sepolia and Georli testnets could be set for trial Merges as well.
