How to verify the manually block signature?

Question

Hi,

According to this: https://www.multichain.com/qa/8071/about-block-signature?show=8071#q8071 the block signature proves the identity of each block's miner. I assume that this signature is verified by succeeding confirmations?

How would we go about verifying the signature manually? We want to demonstrate to a client that that the signature can be used to prove who signed a block.

Thanks

The signature on each block stands alone, and doesn't require subsequent blocks in order to verify it. You can find a small amount of technical information on this here:

But really, you can trust the miner field in the output for getblock or listblocks, since this is based on each node's independent verification of the miner signature.
