- Ropsten, Ethereum’s Longest-running proofof-work testnet, now proof-of stake It In the fourth quarter 2022, it will be closed.
- Rinkebya geth-based proof of authority network I won’t do it Transition to proof-of stake and the transition will be completed in the second and three quarters of 2023.
- Users Developers and architects are encouraged to migrate. Goerli Or Sepolia Test as soon as you can Ethereum In a context after merger. After The merger Rinkeby It will not happen. provide a test environment that is suitable for the Ethereum mainnet. Unplanned The application of mainnet updates to obsolete testnets is not possible.
Ethereum Many testnets are available to developers and users for testing before you interact with the mainnet. These These copies are in effect duplicates of the Ethereum In which mainnet Ether These tokens and any other tokens have no worth. They Developers of tools, protocols, infrastructure and applications can make changes to their products or to the protocol. In a low risk environment, before moving on to the main networks.
That Moreover, testnets are fully-featured blockchains. Their history and status will grow over time. This It will eventually become more difficult to manage nodes and keep them running. For This is why some testnets get periodically cancelled. This Last year, the Pyrmont Beacon Chain Test Network And more recently, with Kovan Execution Layer Testnet.
With The Merge With the close of the year, client developers have decided that they will deprecate additional testnets to allow them to concentrate their efforts on properly maintaining only two of these for long-term success. Goerly Sepolia.
Alert: Kiln, RinkebyAnd Ropsten Testnets have been deprecated.
Testnet Timeline for Closing
Although these testnets are now deprecated, developers and users have plenty of time to plan for their move before they are fully closed. Kiln, Ropsten Rinkeby According to the following timeline, they will be removed.
Furnace: After The Mainnet Merger
The Kiln The testnet was established in 2022 as a post-merger environment. It will be shut down soon after. Ethereum Transition to proof-of stake for mainnet, which is planned for the second half 2022.
Developers Currently using Kiln As a test/test environment, should migrate to Goerli Or Sepolia.
