Good Afternoon,

Proof-of-stake sounds like an altcoin fork. There is no consideration that proof-of-work is insufficient or that it can be improved upon, only that it should be regulated. Imagine, you are a gold miner with larger hands so you start a mining race and mine plenty more than everyone. Pretty soon everybody is employing all their available resources just to keep up in the mining race since there are only so many carts instead of just to leisurely utilise surplus resources for an opportune find. Each block is a new gold mine. It is enough for everybody to use leisurely resources.

I have initiated conversation previously regarding a method to regulate mining, and believe whole heartedly it should happen. That is necessary for the future stability of Bitcoin as it is clear the rate of work cannot be allowed to increase at such a rate. If you search the bitcoin-dev archives you will find discussion there under my email as we search for a solution.

Subject: Re: [bitcoin-dev] Opinion on proof of stake in future

To reiterate some of the points here. My problem with proof of stake is twofold.

1. It requires permission of coin holders to enter into the system. This is not true of proof of work. You may even attempt (though not successfully) a proof of work with pencil and paper and submit the block from a regular laptop if you so choose. Whether this level of permissionlessness is necessary is up to individual risk tolerance etc. but it is definitely the default preference of Bitcoin.

2. Proof of stake must have a trusted means of timestamping to regulate overproduction of blocks. This introduction of trust is generally considered to be a nonstarter in Bitcoin. Proof of Work regulates this by making blocks fundamentally difficult to produce in the first place.

Like Jeremy, I’m always interested to learn about new attempts in consensus algorithms, but the bar to clear is very high and proof of stake to date has not proposed much less demonstrated a set of properties that is consistent with Bitcoins objectives.

 the only issue i see with a quality PoB implementation is a robust
solution to the block-timing problem.

i do think there *could* be other low-energy solutions to verifiable
timing, just haven't seen one
