It's possible. There's no tool to do it, though.

Okay thanks. And that will then be all orphans that occurred network wide, not just local ones.

No, it's just local ones. There's no way to get all network-wide orphan blocks. Some might only spread to a few dozen peers.

Interesting, so there is no one true block chain, except for the core. They are distinguishable by their orphans.

Is it possible to "combine" two different block chain data sets, i.e. have the orphans (and other diff. data) added to a new chain containing both sets of information?

They're stored in your block database forever. You'll see them along with the other blocks if you use -printblock or -printblocktree.

Hoping there might already be something like block explorer to analyse them. I'd like to get timestamps out of them and the blocks occurring before and after orphans.

I haven't seen anything browsable, but they do happen, and they are generally resolved within 1 or 2 blocks.

So is there no record kept of them?

The debug.log prints a "REORGANIZED" message for the nodes that were working on the orphaned chain, correct?

Are these the same as the "Invalid" blocks that the pools sometimes report?

Anybody got a database or similar of orphan blocks?

How often are they occurring, (have they occurred)?

Time to solve for following blocks, chain reorganisations, etc?
