Ethereum Foundation Announces Kiln Testnet Shutdown

Ethereum Foundation in an official announcement on September 9 said the Kiln testnet will be shut down next week as the testnet is now deprecated. The Kiln was launched in early 2022 for testing post-merge Ethereum prior to existing testnets merging. All bootnodes and validators related to the testnet will be turned off.

“While anyone can run a node on the network, bootnodes and validators maintained by client and testing teams, as well as infrastructure providers, will be turned off at that point.”

Other Merge testnets Ropsten and Rinkeby are also deprecated. It should be shut down in Q4 2022 and Q2 2023, respectively. While the testnets will remain active after the Merge, infrastructure providers may gradually remove access to Ropsten and Rinkeby testnets with time. Ethereum’s longest-lived proof-of-work testnet Ropsten has transitioned to proof-of-stake, but client developers have decided to deprecate it.

Users and developers must migrate to Goerli or Sepolia testnets as developers decide to maintain and upgrade these testnets after the Merge. Goerli has an open validator set, useful for testing complex smart contracts, and requires more storage. Whereas, Sepolia has a closed validator set, is less used than other testnets, and requires minimal storage.

As per OKLink “Ethereum The Merge Countdown” data, the network hash rate is 885.77 TH/s. A hash rate of 872 TH/s is enough to trigger the Merge on September 15. However, the hash rate has jumped near 900 TH/s.
