Hey @doitian, I followed these steps for forking mainnet into devnet and it worked like a charm, thanks!
Now I want to speed up this devnet to test dCKB and NervosDAO interactions, so I followed the steps you previously suggested, but the epoch length doesn’t seem much affected by them. Currently one epoch is more than 16 minutes.
As indicated in your current answer, I didn’t change the genesis_epoch_length. To fully reproduce this issue follow the steps indicated on the Readme.
How should I proceed?
