Recently, mempool added a new page showcasing a dynamic and live version of b10c research on the merkle branches that miners receive from Stratum V1 Pools. Apart from payment flows, this is another great way to detect which pools are closely linked together or acting as proxies.

The new mempool site can be found under this URL: https://mempool.space/stratum

And you should see something like this (image down below), were, if you wait long enough, you'll see in real time how pools change what they are mining.

The original research by b10c can be found here: https://b10c.me/observations/12-template-similarity/

This all highlights how mining pools coordinate behind the scenes, and which pools are tied or beholden to which pools.

In short, Stratum V2 fixes this!

Let me know if you want a deeper breakdown of b10c's research report and what this all means.

May the Hash be with you!
