The testnet Ethereum Merge has been completed successfully on the Ropsten testnet, and developers are now focused on the final merge in late Q3 or early Q4 2022.
Ethereum’s testnet has successfully migrated to the new Proof-of-Stake (PoS) consensus algorithm. This means that Ethereum has completed its first step towards a PoS future.
The next step will be to execute a final merge of the Ethereum testnet on Ropsten with the mainnet. This is scheduled for late Q3 or early Q4 2022, when developers will begin working on sharding after the transition to PoS is complete.
Sharding refers to a process in which transaction histories can be separated into individual shards that can be processed at different speeds and in parallel, allowing for greater scalability in terms of throughput and transaction volume.
Following this transition, developers will turn their attention to sharding.
Ropsten’s testnet, also known as Ethereum’s first dress rehearsal for the impending Merge, which will see the present Ethereum mainnet merge with Beacon’s Proof of Stake system, successfully completed the Merge yesterday.
Parithosh Jayanthi, a developer at the Ethereum Foundation, said that the Ropsten testnet met the TTD of 500000 000 000 000 000 at roughly 16:00 UTC on Wednesday, and the chain was merged thereafter.
According to the creator, the Ropsten testnet was “nearly” bug-free, although he did identify a few bugs that needed to be addressed. In addition, “some client pairs timeout while generating a block and propose with 0 transactions,” which would decrease the chain’s throughput. “This was also seen in shadow forks! Fixes are on the way! “.
There are a few more weeks of monitoring ahead of time to ensure that “no client pairings get out of sync,” according to the engineers.
Goerli and Sepolia are the next two testnets slated to undergo mergers before the main merge. Though the number of users may rise, the merger will have no effect on Ethereum’s transaction performance, meaning no change in the average transaction cost.
