Kiln, The Merge public testnet is now live!. #TestingTheMerge is a Ethereum Community Initiative started by Marius van der Wijden and Parithosh Jayanthi to test The Merge.

Kiln, in simple words, means an oven, a furnace used for burning, baking, or drying something, especially one for firing pottery, calcining limestone, or baking bricks. In the context of Ethereum blockchain, it represents the testing of the Merge upgrade where developers want to thoroughly test before the mainnet release. The first public testnet, Kintsugi, was released about 3 months back, which helped setting up the ground. The popular fuzzer issue was a good learning experience for the enhancement in specs. If interested in learning more about Kintsugi, checkout blog and explanatory videos to join the Kintsugi testnet.

How is Kiln Testnet Different from Kintsugi?

Kiln is most likely the last public testnet that we will have before the merging of existing public testnets like Rinkeby, Ropsten, Goerli, and Sepoilla starts. One of the major changes introduced in Kiln Testnet is the implementation of JWT based authentication, so now between the Engine API and the Consensus Layer there is an added layer of authentication. There will be a long Proof of Work phase so that whoever wants to join can run their miners, deploy all of their contracts, and actually see what happens during the transition.

FAQs

How long will Kiln Testnet run?

Kiln Testnet will run until there are no breaking changes. If the spec is doing great with none of the client teams having any more requests or there are no more edge cases, then even if it runs for a shorter duration, that's enough.

How likely are spec changes to occur after Kiln v2?

Unless the team or developers are not able to find any major changes, then it's just going to be minor changes introduced after Kiln v2.

What is the Role of public offering like Kurtosis & Chaos engineering in the Merge?

Kurtosis is an ethereum merge module with its own github repo and we can write tests for it so if anyone is interested in getting involved writing tests using that module it will be very impactful. Chaos engineering is very impactful but will be very helpful in future. To know more about it, Click here.
