Cache header validation point (in case of crash) #4518

Feature Request

Is your feature request related to a problem? Please describe.

When using CKB with assume_valid, currently the header verification always starts at block 0. In the case of a crash, header validation begins at block 0 again

Describe the solution you'd like

While header validation is ongoing, cache in the ckb node the latest header that has been verified, so in the case of a crash the node can start at the latest point

Great idea! As the number of blocks increases, the time consumed by Header Sync is also increasing significantly. CKB is planning to use the Light Client protocol to replace the Header Sync process to address this issue.
