Ethereum simply reached an enormous milestone. On Wednesday June eighth, an Ethereum testnet named Ropsten efficiently transitioned from its Proof-of-Work (PoW) consensus mechanism to the Proof-of-Stake (PoS) mannequin, taking us one step nearer to the mainnet model.
The Merge is seen as a very powerful improve to the Ethereum blockchain because it delivers on greater than six years of effort. Ethereum’s blockchain merge goals to mix the ETH2 Beacon Chain and the Ethereum mainnet, transitioning the community from PoW to a PoS-based consensus mechanism.
The Merge was adopted and celebrated on-line with a livestream occasion. ETH builders will deploy the change on the Goerli and Sepolia testnets to make sure the Merge is sound earlier than conducting it dwell on the mainnet.
The Ropsten network just merged!

The Ropsten Merge
Named after a Stockholm metro station, the Ropsten testnet is a pre-configured PoW Ethereum check community, created round 2016 for builders to check Ethereum-related purposes. As it’s the solely simply accessible PoW testnet, and is ready to host all the primary ETH purchasers, Ropsten offers a really correct testing floor for the primary Ethereum chain, having proved itself helpful to devs testing their code previous to committing it to the mainnet.
Most not too long ago Ropsten can boast proving that Ethereum can transfer from PoW to PoS after a profitable check of the merge on June eighth 2022, marking a giant step within the cryptosphere in direction of a more moderen, higher, shinier Ethereum.
How did we get right here? That is the results of an effort spanning six years, and the ultimate achievement that made it potential to maneuver to testnets have been the shadow forks.
One other degree to ‘The Merge’ testing began in April of this 12 months with the usage of six ‘shadow forks’ – which sound like, however are usually not, cutlery utilized by darkish lords. A shadow fork is made when a brand new developer community is created from the fork of an lively community, however with solely a small variety of nodes, used as an instance how nodes will react within the hardest potential situations.
A shadow fork is just like a testnet, however holds a replica of a separate community, both from one other testnet or the Ethereum mainnet, as an alternative of getting its personal state. As a result of these shadow forks can be utilized to practise a merge to PoS whereas sustaining mainnet transactions and different mainnet state knowledge, they’re proving to be a key instrument within the preparation for the actual life merge.
After the shadow fork exams, it may be mentioned that Ethereum has handed a serious check part with a profitable merge. A problem that got here up was with block proposals not being optimum, which the dev groups are wanting into for the following exams.
The Goerli and Sepolia testnets
So, what’s subsequent? Effectively, two extra merges on the following testnets.
Sooner or later in 2022, the Ropsten testnet will probably be retired, giving method to two different testnets named Goerli and Sepolia the place the following part of testing will go down.
The Goerli Ethereum testnet, created in November 2018, is subsequent in line because it’s a very good illustration of the complexity of the mainnet and can present the related threat.
Because the penultimate step within the merge course of, Sepolia testnet created in October 2021, is by far the perfect copy of the Ethereum manufacturing surroundings and is the essential acceptance check for accepting the merge course of for the mainnet.
What’s subsequent for Ethereum?
After the success on the Ropsten testnet, and the work accomplished with the shadow forks, it’s simple to visualise the Ether devs arduous at work checking diagnostics and bug searching, and we will say with confidence that this profitable merge check will result in the following part of testing, with Goerli and Sepolia testnets up subsequent.
We wish to congratulate everybody engaged on this momentous process and applaud your efforts!
As to the long run, the timeline for additional exams and the ultimate merge is as murky as ever, however we will all hope that quickly sufficient, the time period ‘Wen Merge’ may be the most recent piece of crypto tradition historical past.
