Digital cash is not useful if it must be globally halted to\nensure its security, and Proof of Work squarely addresses this concern.\n\u003e\n\u003e Above and beyond any security consideration, Proof of Stake incentivizes\nthe accumulation of wealth within a small set of actors, which is\nundesirable for the long-term health of any such network.  If we are to\nfree humanity from the tyranny of the State, we must do so by protecting\nthe rights of every individual to hold and preserve their own value,\nwithout trusting any third party.  Entrusting the health of the network to\nthe \"economic elite\" is the paramount evil with respect to Bitcoin's\nobjectives, nevermind that Proof of Work relies on energy expenditure to\nprovide its security.\n\u003e\n\u003e Sincerely,\n\u003e\n\u003e Eric Martindale, relentless maker.\n\u003e Founder \u0026 CEO, Fabric, Inc.\n\u003e +1 (919) 374-2020\n\u003e\n\u003e\n\u003e On Fri, May 7, 2021 at 6:50 PM SatoshiSingh via bitcoin-dev \u003c\nbitcoin-dev at lists.linuxfoundation.org\u003e wrote:\n\u003e\u003e\n\u003e\u003e Hello list,\n\u003e\u003e\n\u003e\u003e I am a lurker here and like many of you I worry about the energy usage\nof bitcoin mining. I understand a lot mining happens with renewable\nresources but the impact is still high.\n\u003e\u003e\n\u003e\u003e I want to get your opinion on implementing proof of stake for bitcoin\nmining in future. For now, proof of stake is still untested and not battle\ntested like proof of work. Though someday it will be.\n\u003e\u003e\n\u003e\u003e In the following years we'll be seeing proof of stake being implemented.\nSmaller networks can test PoS which is a luxury bitcoin can't afford.\nHere's how I see this the possibilities:\n\u003e\u003e\n\u003e\u003e 1 - Proof of stake isn't a good enough security mechanism\n\u003e\u003e 2 - Proof of state is a good security mechanism and works as intended\n\u003e\u003e\n\u003e\u003e IF PoS turns out to be good after battle testing, would you consider\nimplementing it for Bitcoin? I understand this would invoke a lot of\ncontroversies and a hard fork that no one likes. But its important enough\nto consider a hard fork.
