Following the successful merge with Ropsten the Ethereum update moved closer to the Goelri and Sepolia Testnets
Ethereum Update Is One Step Closer, Tests On Ropsten Continue
After the Merge on Ropsten on Wednesday, Ethereum’s move from a Proof-of-Work to a Proof-of-Stake consensus mechanism is one step closer. Although a few issues were discovered, the test was overall successful.
A few clients experienced timeouts during block production and failed to validate transactions, according to a core developer on Twitter. According to Tim Beiko’s tweets, fixes for the problem are already in the works.
While tests and monitoring on Ropsten continue, ETH engineers have urged the community to help by keeping a watch out for issues.
An Important Milestone For Ethereum
The Merge simulation on the testnet represents an important milestone as developers move closer to a mainnet launch.
Ropsten is one of the oldest testnets on the Ethereum network, and the Merge simulation on the testnet marks a significant moment as developers move closer to a mainnet launch.
Ropsten’s code was coupled with code from the Beacon chain during the test to see if block production and validation would go well during the transition.
The Beacon chain is a sister chain that runs alongside Ethereum’s main network and uses an optimized PoS consensus mechanism.
Goerli, Sepolia Testnets
The Merge will take place on two critical public testnets in the coming months, ahead of the mainnet launch, which is planned to take place between August and October 2022. Within the following few weeks, Goerli and Sepolia will be subjected to tests.
According to Tim Beiko’s tweet, other testnets, such as Kiln, would be shut down before the end of the year.
With The Merge network upgrade, the Ethereum blockchain will move to Proof-of-Stake (PoS) consensus. Ethereum developers are expected to keep Sepolia, a PoW testnet, and Goerli, the current PoA/PoS test network.
Ropsten, on the other hand, will no longer be supported by the go-ethereum team. It’ll stay online as long as people keep mining on it. Even after the Merge, Prater, the current Proof of Stake test network for Beacon chain, will continue to exist.
