📝 Original message:Mr. Singh,
Proof of Stake is only resilient to ⅓ of the network demonstrating a
Byzantine Fault, whilst Proof of Work is resilient up to the ½ threshold.
You can explore prior research here:
https://download.wpsoftware.net/bitcoin/pos.pdf
Independent of the security thresholds, Proof of Stake requires other
trade-offs which are incompatible with Bitcoin's objective (to be a
trustless digital cash) — specifically the famous "security vs. liveness"
guarantee. 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.

📝 Original message:Bitcoin's security is derived from the energy consumption of mining, so
reducing the overall expenditure would be an objective decrease in
resilience. As a miner, your efficiency at converting energy into
hashpower is the driving factor in your profitability, so this and any
other future attempts to decrease the cost of attacking Bitcoin receives a
hard NACK from me.
If you're concerned about missing out on the subsidy or fee revenue, grab
any number of the sub-500mSAT USB miners and get access to cheap power.

📝 Original message:We need to make it so mind-numbingly simple to "run Bitcoin correctly" that
the average user doesn't find reasons to do so in the course of normal
use. Right now, Coinbase and Bitstamp are winning in the user experience
battle, which technically endanger the user, and by proxy the Bitcoin
network.
Multi-sig as a default is a start. It won't succeed unless the user
experience is simply better than trusted third parties, but we need to
start the education process with the very basic fundamental: trusting a
third-party with full access to your Bitcoin is just replacing one
centralized banking system with another.
