BitTorrent Inventor Bram Cohen Will Start His Own Cryptocurrency (torrentfreak.com) 104
Bram Cohen, the creator of BitTorrent, has showed deep interest in cryptocurrency in the past, and now it looks like he is going to start his own. From a report: Without going into technical details, Cohen believes that Bitcoin is wasteful. He suggests that a cryptocurrency that pins the mining value on storage space rather than processor time will be superior. In an interview with TorrentFreak's Steal This Show, Cohen revealed that his interest in cryptocurrencies is not merely abstract. It will be his core focus in the near future. "My proposal isn't really to do something to BitCoin. It really has to be a new currency," Cohen says. "I'm going to make a cryptocurrency company. That's my plan." By focusing on a storage based solution, BitTorrent's inventor also hopes to address other Bitcoin flaws, such as the 51% attack. "Sometimes people have this misapprehension that Bitcoin is a democracy. No Bitcoin is not a democracy; it's called a 51% attack for a reason. That's not a majority of the vote, that's not how Bitcoin works."

That's exactly how Bitcoin works.
If you control more than 50% of the nodes storing the blockchain, you can manipulate the currency to your heart's content.
If you do it in such a way that someone notices, people will fork the blockchain. Forking the blockchain has already happened due to other issues. And it went about as smoothly as anyone could have hoped for.

This is correct. If you have 51% of the hashing power for a period of time you can double spend (ie spend your bitcoin; take it back and spend it again - the BTC version of counterfitting). Of course if you do that you devaluate the value of BTC
However, BTC is getting too centralized. One of the basic premises behind BTC was that anyone and everyone can mine to one degree or another with their CPU. With the advent of ASICS that's no longer the case.
Only with CPU only hashing (ok, if you insist, GPU only hashing) will Bitcoin come close the ideal that everyone is a node and everyone has a roughly comparable stake.
Even if I have 100,000 CPUs and you only have one we'll be more "equal" than now where you have one CPU versus people with ASIC farms.

The answer is No.
here's why:
Any(one)thing that can be done on a CISC can be done on an ASIC.
If you had an algorithm that say used the L1 cache to do some funky physics based transform (nevermind that this is a *bad* idea because new steppings will change the device physics) then you could design an ASIC that had only enough compute to run the L1 cache and devote the rest of the ASIC die to having 40 or 50 L1 cache fields.

If the switch happened *after* the ASIC was created then yes.
If the algos are all defined then I just build an asic that does the following:
get input
switch (input.algo){
case Algo1: { foo();break;}
case Algo2: { bar();break;}
case AlgoN: { doN();break;}
default: {awNuts();}
};
put output
Sure the ASIC is bigger (and costlier), but each of those algos is a hardware implementation optimised for nothing else.
An ASIC is (basically) a slice of a RISC that does what you want with nothing else.
In fact you can think of a RISC as an ASIC implementation of CISC.

Owning the network and owning the hash power are separate things.
If you own the network, then you can lie to other nodes about stuff. Other nodes would be like "WTF?" and the network would split. But that's not automatic, and until people can trace back and find out which nodes are janky, you can profit in the chaos.
This sort of attack needs storage and network resources, not computational resources. For a successful attack giving you a usable time window in which to take action, you would want the network to be as distributed as possible.
With hashing power you can "change the order of transactions", sure, but as others have pointed out that means you can spend BTC you don't have, fuck other transactions, etc. This is the attack everyone worries about because the Chinese ASIC farms basically control Bitcoin at this point. But they're not controlled by a single entity and any shenanigans would again be met with a fork.

51% would be a majority of the vote. That's how Bitcoin works. It's still a democracy. Democracies can use majority voting vs plurality voting, include runoffs until a majority is reached, or some manner of supermajority.
Have you considered that maybe, just maybe, democracy has more to do with who can vote than where you set the finish line?

I believe what he's trying to say is that a majority when weighted by mining power isn't the same as a majority when weighted equally (i.e. one human per vote). In that sense it is fairly different from traditional conceptions of democracy and closer to plutocracy.

Sorry Bram, but you are missing the point. Hashing is used in bitcoin precisely because it is useless. It can't be faked, and it can't be stored for later. It is an irrevocable commitment right now.
I wish you luck with monetizing distributed storage, or decentralized distribution, or whatever your new project ends up as. But the design of bitcoin is not a programming challenge for you to solve. It is a carefully interlocked design, made by someone (or some people) who has (or have) a far beyond average understanding of money and cryptography.

Well, I'm not defending Bram on his quest, but I would say that based on this presentation [stanford.edu] at least he seems to know enough to know that he doesn't know how to do it yet (which is one step above those that don't even know what they don't know yet)...
