Find all raw headers that have same nonce

[coinscashout]

Is there a quick way to find a details of different raw headers that all have the same nonce other than manually looking (if so how)

Thanks

You could probably write a script that connects over RPC, retrieves and decodes the block headers and then compare the retrieved nonce values.

Seems like a hell of a lot of work. I was under the assumption I could search it over the net some how

It's really not hard. You don't have to decode anything - just store all the nonce values and block hashes, given by `getblock x`

Thanks mate.
