"Hey guys, I just got my morning cup of coffee in, and I'm still trying to wrap my head around this - it looks like a dev just pushed a commit to the main Bitcoin repo that supposedly enables a new 'opt-in' stealth address feature. From what I've gathered, this means users can now create temporary, non-linkable addresses for their transactions, which could have huge implications for on-chain privacys. Has anyone else seen this and have any thoughts on the implications?"
