Hi, all

As we all know that Bitcoin users can have more than one Bitcoin addresses.

I am looking for every possible ways to group addresses based on their ownership.

After doing some research about this topic. There are currently two popular heuristics.

--------------------------------------------------------------------------------------------------------------------

Heuristic1: Grouping all the input addresses of transactions to the same cluster.

Heuristic2: Grouping the change addresses (shadow addresses) to the same cluster of the input addresses.

--------------------------------------------------------------------------------------------------------------------

What I want to do is to develop another heuristic. So far I am thinking to group addresses based on its transaction patterns.

Such as peeling chain, or the addresses that distributed bitcoin to many other addresses and converge in the end.

Is there any other transaction patterns that we can identify its ownership?

It is just the initial idea. Any idea, advice or relative works would be appreciated
