Ethereum's Kiln merge testnet will be shut down during the week of September 12, 2022, as The Merge upgrade approaches. The announcement also mentions that other testnets Ropsten and Rinkeby are being deprecated as part of the transition.
Ethereum's Ropsten testnet has set a Terminal Total Difficulty (TTD) of 50000000000000000 for its transition to Proof-of-Stake. Stakers and node operators must manually configure their execution and consensus layer clients before June 7, 2022.
Ropsten testnet became the first longstanding Ethereum testnet to undergo The Merge transition. A new Ropsten Beacon Chain was launched on May 30, 2022, with the network scheduled to upgrade to merge-compatible protocol rules (Bellatrix) at slot 24000 on June 2, 2022.
The Ethereum London upgrade is ready for testnet deployment, launching first on Ropsten at block 10499401 around June 24, 2021. This follows the recent Berlin upgrade that was activated on the Ethereum mainnet a few months prior.
Ethereum's Berlin upgrade is scheduled for deployment with Ropsten testnet upgrading on March 10th and mainnet on April 15th. Node operators must upgrade to Berlin-compatible versions before the deployment dates to maintain network compatibility.
The Ethereum network is scheduled to undergo the Byzantium hard fork at block 4,370,000, expected to occur between 12:00-13:00 UTC on October 16, 2017. The Ropsten test network already successfully completed the hard fork on September 19th at block 1,700,000.
The Ropsten Ethereum testnet is being officially shut down in the coming weeks due to declining infrastructure support and validator participation. Most remaining validator nodes will cease operations as part of the planned deprecation process.
Ethereum is deprecating several testnets including Ropsten, Rinkeby, and Kiln following the network's transition to proof-of-stake. The Gray Glacier upgrade was scheduled for block 15,050,000 in June 2022, with testnet shutdowns planned for Q4 and after mainnet's merge completion.
