It’s kind of crazy to think that digital supply chains are currently more opaque than physical supply chains. But here we are. We know which garments are manufactured in Xinjiang, but we don’t know which Bitcoins are mined there.
Agreed that we need to find ways to make PoW crypto (mainly Bitcoin) more climate friendly. But another key goal for Bitcoin is fungibility which seems inconsistent with tracking the provenance of each coin. Sure, PoS doesn't have the same climate problem but it is likely to end up being much more centralized because there is no natural way to dilute the holders/stakers. Seems to me that market forces to drive down the price of renewables is the only viable option. If we can encourage / speed up those market forces, even better.
