WARNING: This thread is somewhat off-topic for this mailing list. It's speculative, we are not working on this at all. The only reason I'm diving into it here is to give people an idea of the sorts of thought experiments we've carried out in this area in the past. Only read it if you're intellectually curious about the area of the "ultimate currency". This email has almost no bearing on the work we're going to be doing here over the next 2-3 years since the technology or infrastructure to accomplish what's outlined in this email doesn't exist yet.

I think Joseph has provided a few links, but it'll take you quite some time to go through the literature. I'm going to try and summarize the thinking in this area in the rest of this email. None of it originated in my head, I'm merely summarizing the thoughts of other people that are much smarter than I am. This line of reasoning came out of the physics and mathematics communities. Everything boils down to physics and mathematics at the end of the day. :P Ultimately, there is only one currency that holds its value throughout time and that is energy. It's the only thing you can store that will keep its value over billions of years. 1 megajoule of energy is going to do the same thing at 1 billion years from the big bang as it does at 10 billion years from the big bang. The best way that humankind has dreamed up to store energy over long timescales is storage as antimatter. Energy per unit mass: Anti-matter: 9 × 10^16 J/kg Fusion : 6.3 × 10^14 J/kg Fission : 8 × 10^13 J/kg Gasoline : 4.4 × 10^7 J/kg The technology to store antimatter at a large scale does not exist yet (and may never exist). Putting that aside, there are less dense ways than antimatter to store energy over long periods of time that doesn't invalidate this theory. Now for the leap of faith: Assume a readily available machine and energy grid that is capable of producing, storing, and retrieving anti-matter over very large time scales. If that's too much of a leap of faith for you, assume a mechanism for generating, distributing, and retrieving hydrogen gas (which does exist today on a small scale, and could be ramped up to become a global energy distribution mechanism if the economies are there to do so). The way that you earn this energy currency is by directing energy into the system (creating anti-matter or hydrogen gas), and the way that you spend the energy is by transforming it into work of some kind ("burning" the anti-matter or hydrogen gas to heat a home, power a car, etc.). So, that's the ultimate currency, but in order for the ultimate currency to be of use to humankind, you must create liquidity and to do that, you must virtualize it in some way. So, you store the reference to the amount of energy you have generated in the Internet in the same basic way that Bitcoin does, as a proof of work. Except in this case, the proof of work isn't the "amount of energy you have burned to create 25 Bitcoins", it is the "amount of energy you have stored in the global energy network". Imagine a power plant where you lease some of the power generation equipment (anti-matter traps, solar-powered hydrogen gas generators, etc.). You'd buy energy generation capacity at the plant, which would then credit your energy account for energy it creates and feeds into the global system. There would be a cryptographic protocol used (much like what Bitcoin, Ripple, or PaySwarm currently use) to assign the energy to your Internet-based energy currency account. So, after a few years, you could see something like this: Energy Account Balance: 62,342.75 MJ That number is as stable as you get as far as a currency is concerned. Since it's extremely stable, it would end up becoming the reserve currency for the world. It will always be worth the same amount today as it would be worth 2 billion years from now. Ultimately, this is where humanity is headed. This is not to say that there won't be other currencies. Humans love to speculate and take short-cuts to wealth creation. Other currencies will also need to exist to model or drive the sort of behavior we'd like to see. For example, we are still going to need to drive societies to do things (like work/save/spend) by inflating or deflating a currency like we do with fiat currencies. Like I said in the beginning of this email, this is an interesting thought experiment. We are nearing the point at which the Internet can support a global cryptographic energy currency. This could provide a universal stable currency for humankind. The piece that is missing to enable energy-based currencies is an equitable, global, uniform energy creation, storage, and retrieval mechanism. Until that happens, we're going to see people approximate energy-based currencies. Bitcoin proof-of-work is such an approximation, albeit as an accidental side-effect of the mining algorithm. So is the research that Joseph Potvin and his colleagues are doing on the Earth Reserve currency (measuring solar energy densities per unit mass of land). -- manu -- Manu Sporny (skype: msporny, twitter: manusporny, G+: +Manu Sporny) Founder/CEO - Digital Bazaar, Inc. blog: Meritora - Web payments commercial launch http://blog.meritora.com/launch/
