I understand a lot mining happens with renewable resources b= ut the impact is still high. I want to get your opinion on implementing proof of stake for bitcoin minin= g in future. For now, proof of stake is still untested and not battle teste= d like proof of work. Though someday it will be. In the following years we'll be seeing proof of stake being implemented. Sm= aller networks can test PoS which is a luxury bitcoin can't afford. Here's = how I see this the possibilities: 1 - Proof of stake isn't a good enough security mechanism 2 - Proof of state is a good security mechanism and works as intended IF PoS turns out to be good after battle testing, would you consider implem= enting it for Bitcoin? I understand this would invoke a lot of controversie= s and a hard fork that no one likes. But its important enough to consider a= hard fork. What are your opinions provided PoS does work? Love from India.
