the Ropsten test network will close permanently in December


Following the arrival of The Merge, the Ropsten testnet is revealed to be gradually abandoned and no longer fulfills its role as a clone of the mainnet. Consequently, the latter will be phased out by December 31. The Rinkeby testnet will be next on the list and is expected to shut down by mid-2023.

The Ropsten testnet soon to be forgotten

According to what the Ethereum (ETH) blockchain development teams announced last June, the Ropsten testnet will close in the coming weeks.

“The vast majority of the remaining validator nodes will be shut down during the period from December 15 to December 31, 2022. After that, Ropsten will no longer be supported by customer, testing, or infrastructure teams. »

The Rinkeby testnet as for him should be the next to terminate his services. The latter will remain active until mid-2023 so that users and developers can migrate to the Goerli or Sepolia testnets, which will remain active and continue to serve as a sandbox for future updates.

Much like Ropsten, Rinkeby became obsolete following the arrival of The Merge update last September on the Ethereum blockchain, moving the network from proof-of-work (PoW) to proof-of-stake (PoS).

Therefore, the developers have – rightly – gradually lost interest in these 2 networks. For information, the block explorer Etherscan no longer supports these 2 testnets since last October.

Sharding, Ethereum’s next step

The next major update to the Ethereum blockchain will focus on sharding, a big step which should finally reduce network transaction feeswhich are a really big barrier to wider adoption.

Last I heard, Ethereum developers have included EIP-4844 “proto-danksharding” to their “considered for inclusion (CFI)” listwhich means that they are currently working on setting it up on the mainnet.

We can therefore expect that EIP-4844 is included in the Shanghai update or shortly thereafter. However, as with any development schedule, it is quite possible that some unforeseen delays may occur, as we have seen for The Merge update.

This new feature, which hides the technical term “shard blob transaction”, will also benefit overlay networks such as Arbitrum or Optimism (OP). Indeed, although the latter already benefit from much lower transaction fees than Ethereum, the latter should still be greatly reduced following this update.
