Ethereum will close down three testnets, following Merge

Only the Goerli and Sepolia testnets will remain operational after the much-anticipated Ethereum Merge is complete.

According to an Ethereum Foundation blog post, the Kiln, Rinkeby, and Ropsten testnets will be deprecated due to the necessity to focus resources on maintaining the two testnets that will remain operational.

However, developers would have time to prepare for their relocation before the system is entirely shut down.

Timetable for shutdowns

According to the blog post, Kiln would be the first Ethereum testnet to be decommissioned. The testnet was created to serve as a post-merge testing environment, and it will be the first to be decommissioned after the transition to a proof-of-stake network is complete.

Rinkeby is the next testnet to be decommissioned. The testnet will be shut down in the fourth quarter of this year.

Between the second and third quarters of this year, Ropsten would be available. It would be deactivated, however, one year after the Sepolia testnet successfully converts to proof-of-stake.

Further facts about the development revealed that once the blockchain update is complete, the duty of maintaining and running the two testnets would be solely the responsibility of client developers.

While Goerli will be integrated with the Prater Beacon Chain testnet, its chain will remain open for anyone interested in running a testnet validator; a new Beacon chain will be introduced to migrate Sepolia to the proof-of-stake network.

Vitalik Buterin expresses concern about centralization

In a recent interview with Fortune, Ethereum co-founder Vitalik Buterin highlighted concerns about the network’s centralization caused by the staking services provided by Lido Finance.

He said:

“I’m definitely worried. I think it is one of the bigger issues that we’re thinking about when trying to figure out how to change proof of stake in the long term. But I also think it’s important to not overly catastrophize the issue because that is what a lot of people do.”
