Problem

Block header items are not correct for current blocks (Cancun era), this would lead to incorrect block hash recreation.

Solution

See this post, scroll to bottom: https://ethereum.stackexchange.com/questions/163229/how-to-verify-block-hash-post-merge-block-15-5m.

My concern is that the generateRandaoProof() is incorrect, because it does not match what I found to be the correct block header items needed to recreate the block hash from a block header.

[qizhou]

The block hash should be correct, and generateRandaoProof() misses some fields introduced in Cancun. A quick fix in #85 will add these field in the header.

Another fix #90 is merged to handle the zero number correctly.
