Your justification for the Th/s being an issue for electricity consumption is one I have seen bounced around a bunch but other than the justification of the environment there are other issues. But, the idea of cryptocurrencies is that without some kind of artificial scarcity you will have other incentives. If you are really concerned about electricity consumption what about using a ledger technology that is designed for low resource consumption such as Sawtooth? I'm not sure how Stellar helps you in this regard. Also, why are you seeking more funding in the first place?



> I'm not sure how Stellar helps you in this regard

Stellar does not use proof of work.

AFAIK Keybase are a for-profit private company.


"Also, why are you seeking more funding in the first place?"

What is the purpose of this question? You want KeyBase, a private entity, to convince you, a stranger on the inter-webs about their plans for said funding? That's giving yourself FAR too much importance. Here's $5 bet that the company will ignore this question.


Electricity consumption is not an "artificial scarcity"


I mean that artificial scarcity is enforced by a distributed ledger system is by using the concept of a miner. The best implementation we have so far that is electricity consumption because this makes people consume electricity which costs them money. If you don't have this piece then people will subvert the proof of work some other way.

For example if you have some type of mathematical problem (the unknotting problem) to take the place of the proof of work then you have to worry that that problem is actually hard to perform. Hypothetically that problem could be quite easy and you can subvert the system by having some shortcut.

But inverting a hash is known to be hard. Through this hardness you get artificial scarcity by making people efficiently design systems to consume electricity.


i wouldn’t say that’s true at all. proof of work isn’t the only “artificial scarcity” that we can have... its paying money to compute some thing to get a vote... why not just put money for a vote? or better yet, prove that you have the means to pay a lot of money for a vote.

if you have to hold a lot of limited thing X (that’s difficult to get; eg $10m worth of ETH) on the very chain you’re securing, then that’s scarcity too.

another benefit here is that you can make a trusted network; that way you don’t have nodes coming and going, you have a group of trusted parties with their own network, and there’s less potential for a 51% attack

electricity and work isn’t the only thing that can be scarce


I think scarcity is a bit of a red herring. The key is that it has to be more lucrative to play fairly than to cheat (well, it also has to resist attacks that are simply trying to destroy the service). Proof of work by itself is not enough. It's the scaling of the difficulty to the potential gain -- the implication being that more people mining == more money to be gained by cheating.

The other thing that is compelling about Bitcoin's proof of work protocol is the ideal that every participant is equal. The whole point is to avoid the circumstance where more money means more control. Now, I think we can probably all agree that this didn't pan out -- whoever controls the big mining pools controls the system. I think that if anyone is going to go to the next level they probably have to step back and look at the problem with fresh eyes. Substituting X into "Proof of X" is unlikely to provide the solution, IMHO.
