According to the blog post Mr. Beiko shared on Hackmd.io, the testing of Ethereum (ETH) specs after merging on the Kintsugi testnet is proceeding as intended.

A number of bugs have been found in API specifications and hash disclosure logics. The latter was immediately fixed, while Engine API improvements will be included in the latest releases.

Specially crafted ephemeral devnets are activated for both upgrades. The “polished” Kintsugi will be replaced by Ethereum’s next testnet, Klin.

Mr. Beiko stated that Ethereum developers interested in experimenting with Kintsugi should hurry. Klin will be the last “new” testnet, while the next will be started by forking existing software.

The next All Core Devs (ACD) call will be on February 11, 2022; Ethereans will discuss Kintsugi’s results and Klin’s prospects for research and development.

Mr. Beiko also described the first post-merger Ethereum upgrade, Shanghai. (The Ethereum Foundation has decided to drop ETH1/ETH2 terminology for good.)

The most critical EIPs will be related to the implementation of new EVM functionality and several UX enhancements put in place to reduce gas costs for end users.

The BLS Precompiles module also triggers the native execution of BLS operations by Ethereum Virtual Machine.
