Expected behaviour

Seal blocks every 2 seconds

Actual behaviour

Doesn't seal any block

Steps to reproduce the behaviour

Running geth locally from genesis file

I see endless transaction indexing is in progress because the blocks are not sealed.

So the issue here is, the chain config contains "terminalTotalDifficultyPassed": true which indicates that the network is post-merge. With this configuration autonomous block production is disabled in Geth.

However, you should also know that Geth v1.14 will no longer support Clique network operation. It will only be supported in a limited way to allow importing old testnet blocks. If you have a Clique-based network you are supposed to transition it to proof-of-stake using Geth 1.13.x.

[0x366]

Thank you for explanation! Could you please elaborate on how to properly handle this scenario in 1.14:

I was using clique for e2e test (for every test I was spinning an empty blockchain with some preallocated contracts and basically was submitting txs and checking their receipts). It was fitting my purpose 100% as I could just auto seal new block every 1-2 seconds and dont need to run consensus client.

How to archive that in 1.14 ? Besides dropping clique and terminalTotalDifficultyPassed fields, I guess I also need to run consensus client ?

[fjl]

You can use geth --dev for testing. It can be configured with a custom genesis block if needed. See https://geth.ethereum.org/docs/developers/dapp-developer/dev-mode for more info.

@fjl Hi, I had a private network with POA consensus (use Clique). I want to upgrade Shanghai for my network, but after investigating, it doesn't support it, right? #26484 (comment)
Currently, this is my Genesis config.

How do I upgrade Shanghai for my network?
