The article is a little on the slop side, but the fact of what they are doing is cool: Vinteum got a group of people working in Bitcoin together to learn, talk, and think about mining for five days.

From August 24 to 28, we gathered a small group at Casa21, Vinteum’s hacker house in São Paulo, for a week-long Deep Dive on Bitcoin mining. Deep Dives are technical gatherings where fellows, grantees, researchers, and experienced contributors spend several days studying a part of the Bitcoin stack together.

This is a cool idea and I think we could probably befit from a lot more of it:

If we want to support work in these areas responsibly, understanding isolated repositories is not enough. We need to understand how the different parts of the mining stack fit together, where their assumptions and interfaces meet, and the problems miners, pools, firmware developers, node developers, and protocol designers are actually trying to solve.

It's particularly enheartening to see this happening outside the US. Imagine if we have robust groups of developers in regions all over the world regularly taking up topics like this to try to sharpen their own understanding to help the industry see things with fresh eyes.

If this sort of practice was normal, I wonder if a group that was looking at hardware wallets would have caught something like the Coldcard vulnerability.
