Taiyi boost GetHeader

[zsluedem]

Describe the bug

Currently, the getHeader method of taiyi boost is not doing anything correctly. https://github.com/lu-bann/taiyi/blob/dev/bin/taiyi-boost/src/builder.rs#L93-L190

1. When taiyi-boost receive getHeader from validator, taiyi-boost should check whether the slot contains contraints.
2. If the slot contains contraints, the taiyi-boost should send a getHeaderWithProof to relay to get the proof.
3. If there is not proof or invalid proof, taiyi-boost should build the block by itself with contraints
4. If the slot doesn't contain constraints, taiyi-boost should by pass the getHeader request directly to relay

@zsluedem I think the correct flow should be as below.get_header_with_proofs can return a header for both cases( w/ & w/o constraints(with empty proofs))

    A[BN requests getHeader] --> C[Send getHeaderWithProof to relay]
    C --> E{Header received?}

    G --> | Yes | M[taiyi-boost Builds local block with constraints]
    M --> H
    E --> |Yes| H[Return header to validator]
   G --> | No | Y[EL fallbacks to local block building]

@zsluedem lets close this?

Why . I thought you agreed with me in tg?

Yeah we can let taiyi-boost receive blocks from non-preconf block builder in future. We can close this since this is not a bug.

[zsluedem]

It is a bug. The taiyi-boost could not handle this situation and failed to build the block

I see, could you show the logs?
