Lets discuss how we can make Bitcoin work for 7 billion people here on EARTH before discussing how to export it to other planets and galaxies

Im afraid the architecture of bitcoin has its limitations if we reach millions of daily users.

Thats the problem, there is too many people on earth to mine Tongue

.. Mars only have whoever that manage to land...

Actually if something like a gem was found in abundance, it wouldn't have much value anymore.
The real scalable materials are those with an actual use, and even those only up to their saturation limit.

I think in the first few years energy on mars could be dirt cheap, in the time mars is collonised fusion energy will be available, and on mars there are no enviromental activists and the like, so produce energy, and dump the radioactive waste in the next hole. And deuterium looks like to be more common on mars.

Mining Bitcoin on Mars is totally infeasible, as almost all blocks mined on Mars will be orphaned by the time they reach Earth. I have talked about a solution before:

Quote from: Foxpup on September 09, 2013, 08:06:05 PM

Each planet will have its own locally-mined cryptocurrency (Marscoin, etc), which each have a floating exchange rate to the original Earth-based Bitcoin. Marscoins and bitcoins can be directly traded for each other in order to settle interplanetary trade balances, the only issue is the speed-of-light delay for confirmations (which is unavoidable no matter what). Naturally Bitcoin can't be mined on Mars and Marscoin can't be mined on Earth, but that's not important.

An interplanetary coin with a block target of several Earth days (to allow interplanetary mining) is also a possibility for interplanetary trade or as a solar-system-wide reserve currency, but probably not necessary as long as the planetary coins can be freely traded, in which case it's likely that Bitcoin will become the solar-system-wide reserve currency (making all previous price predictions seem hopelessly pessimistic).

Yeah that's what I was thinking - thanks!

If you could use quantum entanglement for instantaneous communication,

then we could send our mining computer into a black hole or somewhere else with massive distorted space time...
for the miner, time may pass at a different rate.. maybe much faster than on earth.. yet you are still getting instantaneous communication..
so.. on earth 10minutes have passed, but the miner has had 5 years to mine blocks in that short period...

Forget about Mars coin, there wont be humans on Mars for decades. But we can have bitcoin in space around the world to make the vision of a free and untouchable internet become reality.

My vision is that we build 1000s of tiny satellites with the following functionality:
-mesh networking
-communication with earth and neighbour satellites
-bitcoin mining hardware onboard
-hosting of websites

These devices can enable a free and uncensored internet in countries like China, it will be slow but it will be work and will be hard to stop unless they shoot down 100s of satellites over Asia.

Incidentally, if mining stops, Bitcoin dies, given it's the only method of propagating transactions. I still don't think it'll be around when Mars is colonized - only because of how long it will take.

so i have another question. if its imposable for entangled particles to transfer information, how could you ever design a test that would show whether two particles were entangled or not. wouldn't that test require that they transfer some sort of information between each other?

You can't tell whether two particles were entangled without knowing the state of both of them. And you can't know the state of a distant particle without measuring it and transmitting the results of that measurement across that distance, which can't be done faster than the speed of light.

k that also makes sense

you would just measure it and when it is in a state than it is a 0 and when it is in superposition than it is a 1.

I am not even able to comprehend the degree of confusion that could provoke such a statement. To measure something means to determine its state. A particle or system of particles is always in some state or another after you measure it, by definition. Superposition can only exist as long as no measurement is performed.

that makes sense. i was just basing my conclusions on what you said, not on my intricate understanding of quantum physics.

I cearainly don't know everything that is to know about quantum mechanics, but I've studied quantum mechanics and quantum field theory for more than 1.5 years now.

The problem is: you can enforce a particle that is in a superposition of 2 states to bee in one of the 2 states over great distances, but you don't get to choose which of the states it gets into.

When your communication partner measures the particles, he can't distinguish between particles that were forced into one state by his measurement, and particles that were in a pure state before. So no communication with quantum entanglement

Ok so maybe you didnt quite explain it properly, but according to the way you explained it you should still be able to communicate information. you would just measure it and when it is in a state than it is a 0 and when it is in superposition than it is a 1.

Nope. Not even gravity will be noted instantly. If I disappeared Earth right this instant, Martians will only notice the change in gravity after the gravitational waves arrive, coincidentally at the speed of light.

By the time humans settle Mars, the block reward would have decreased significantly and will no longer be an important factor of mining. The solution, consequently, is simple: add a "second genesis block" to Bitcoin. These blocks are identical to regular blocks, except they employ a different hashing algorithm (to prevent Earth-miners from overtaking the Mars chain), and primarily deal with transactions broadcast to Mars. Interplanetary transactions will certainly take a while, as the Mars blocks will need to be broadcast to Earth, but are seamlessly integrated into the system. Transactions limited to a single planet work as expected.

Every time a new planet is settled, new genesis blocks can be created, one for each planet.

True, whichever planet has the largest hashing power will eventually dominate. Regardless of who "wins", it's not good for Bitcoin as interplanetary currency. Only if the communication delay is negligible compared to the average block-time, will it interplanetary mining be feasible. A coin with a 24hr block-time can be mined on Earth and Mars just fine (assuming a network connection can be established of course).

Using bitcoins as interplanetary currency has been discussed here before, several times.

The only method that makes sense to me is for each planet to have their own version. Travelling from earth to Mars? Sign in to your local exchange before you go and trade some bitcoins for Marscoins. Mining bitcoins would only work for earthlings and mining Marscoins would only work for Martians.

This could get interesting when miners start hopping planets to take advantage of hashrate and price discrepencies.

You will be more profitable to do real mining on mars.

As far as I understand you could spend a Bitcoin on Mars. The light travel time means it could take up to 30 minutes to get the first confirmation, so that's not a massive problem.

But what about having miners on Mars, perhaps to speed up confirmation times for colonists.

How would the protocol fair when say a block is found on Mars and it could take nearly half an hour for it to arrive on earth?

Last I check there is no internet connection in Mars

laser beam? Huh

you mean line of sight.....yea right thats totally economical to limit internet to a 20 minute window each day.
back to reality - don't you think btc will be antiquated? I don't see humans populating mars at all...or by the time they do, bitcoin will be obsolete completely. Just cause its a thought doesn't mean it makes any sort of good sense. Mars makes sense like living on the moon does....it doesn't.

Mining Bitcoin on Mars is totally infeasible, as almost all blocks mined on Mars will be orphaned by the time they reach Earth. I have talked about a solution before:

Each planet will have its own locally-mined cryptocurrency (Marscoin, etc), which each have a floating exchange rate to the original Earth-based Bitcoin. Marscoins and bitcoins can be directly traded for each other in order to settle interplanetary trade balances, the only issue is the speed-of-light delay for confirmations (which is unavoidable no matter what). Naturally Bitcoin can't be mined on Mars and Marscoin can't be mined on Earth, but that's not important.

An interplanetary coin with a block target of several Earth days (to allow interplanetary mining) is also a possibility for interplanetary trade or as a solar-system-wide reserve currency, but probably not necessary as long as the planetary coins can be freely traded, in which case it's likely that Bitcoin will become the solar-system-wide reserve currency (making all previous price predictions seem hopelessly pessimistic).

If we can get a fast enough connection between another planet and Earth, it could be possible.

Speed of light is the "fastest internet connection" you are going to get. Which leaves you with a transmit time of between 3 and 22 minutes, depending on the orbit.

The protocol must be adjusted for the lag in time between nodes at planet A and B so they can have a chance to sync with each other.
each block will need to be at least lag_time * 2 = 1 hour for all nodes to accept the blockchain
