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 in preparation for the main Ethereum blockchain to switch to proof-of-stake (PoS) consensus.
Ethereum DevOps engineer Parathi Jayanathi submitted a pull request for the Ropsten testnet Merge configuration code on Monday, which suggests that the code is ready to be implemented.
The Merge is Ethereum's long-awaited upgrade when the current Ethereum Mainnet will merge with the beacon chain PoS system.
So far, there have been multiple tests to investigate how the merge would function. Just last month, Ethereum developers began testing how the switch would work on a shadow fork.
One of the final checks would be to test how the merge would work on Ethereum's main public testnet. As such, the Ropsten public testnet is seen as the best replication of the Ethereum Mainnet as it follows a similar network structure, enabling developers to test their work in a live setting.
