Digital cash is not useful if it must be globally halted to ensure its security, and Proof of Work squarely addresses this concern. > > Above and beyond any security consideration, Proof of Stake incentivizes the accumulation of wealth within a small set of actors, which is undesirable for the long-term health of any such network. If we are to free humanity from the tyranny of the State, we must do so by protecting the rights of every individual to hold and preserve their own value, without trusting any third party. Entrusting the health of the network to the "economic elite" is the paramount evil with respect to Bitcoin's objectives, nevermind that Proof of Work relies on energy expenditure to provide its security. > > Sincerely, > > Eric Martindale, relentless maker. > Founder & CEO, Fabric, Inc. > +1 (919) 374-2020 > > > On Fri, May 7, 2021 at 6:50 PM SatoshiSingh via bitcoin-dev < bitcoin-dev at lists.linuxfoundation.org> wrote: >> >> Hello list, >> >> I am a lurker here and like many of you I worry about the energy usage of bitcoin mining.

I understand this would invoke a lot of controversies and a hard fork that no one likes. But its important enough to consider a hard fork.
