Again, what do you think about commodity-backed cryptocurrencies, maybe a silver-backed, gold-backed, a cryptocurrency backed by a basket-of-goods? Do you think they can outshine other cryptocurrencies that are only based on mere fundamentals?
I am not sure if a commodity-backed cryptocurrency could be a reality in a trustless manner. If it could, it'd be awesome imo. But the separate investment in gold & silver has its beauties - you do not get that feeling of holding a beautiful coin in your hand with BTC (there are physical BTCs, but that still doesn't make BTC be 100%
physical).
I'm not sure they could outshine Bitcoin, for example. The way I see it, it's going to probably remain the king for a very long time due to the fact that it's been proven to work as it was intended to and it's been successful through lots of different attempts.
In a crisis where barter becomes a thing and internet connection is still affordable, Bitcoin could thrive easily due to its transparency and immutability. Gold could be faked, you'd have to trust someone else's words as you can't check whether the coin is 99.99% gold or not. I don't think backing a crypto with gold would give it many advantages overall.
Here comes the problem: that is only if you already have the knowledge inside your head or bought the necessary stuff. But in case of an internet outage, +95% of the people wouldn't have any option to make use of their coins. If internet fails, people will probably have way more important things to care about than purchasing bicycle generators.
I find local Blockchain/Bitcoin interesting (not in that links^ page). It should be possible to build something that can be used locally and later sync with World's Blockchain whenever there is internet. Whether it takes 2year to find internet for synching shouldn't be a problem as long as the data is well decentralized, fool-proof, secure etc
Another interesting idea is to create a physical Blockchain/decentralized-system that is totally independent of the internet.
So after 2 years of having no internet, would you trust the blockchain you'd get connected to? Would they trust us? Because at one point, someone could maliciously revert the blocks to their own advantage and give you a connection to their own version of the blockchain.
What if someone uses a device offline to send you 10 BTC and then goes to a place where there is internet connection and sends the same amount to a different address, but online and from another device? You would have no idea their BTC were double-spent and once the blockchain goes live.. oh well, your 10 BTC would become obsolete.
