Do you have thoughts on a transition strategy that takes into account the vested interests of existing miners in the Bitcoin network?  (money, equipment, energy, location) after all, they are the ones to be tempted in a more environmental direction. At this point i am more interested in a tempting transition strategy than any secure principle... in my opinion this needs to be a slow transition over many years where hashing is phased out... Thanks for the post!

Great piece of thought provoking stuff. You are raising allot of questions i have been asking myself since the time i have been putting my interest to blockchain in great fascination. I also realy like the early comment about how we as humans have a hard time grasping the concept of money and its role in human societies. I agree with most of the points you raise, especialy how international transfer and speculation seem to be the only dominant usecases for crypto now. All the smart contract stuff may be usefull, but seem mostly unrelated to the currency or even the blockchain aspects in many cases... Ppl tend to talk about the potential of untraceable privacy coins like Monero, however i can see how the simplicity and transparancy of the Bitcoin system can create opportunities. I am working on a white paper, in an effort to put some new economic fundamentals under the bitcoin system, making it less volatile and rationalize its vallue. I call it the ypsilon project, but i think i might need some help... thanks for your post.
