With the recent US Judge ruling (effectively a fiat declaration btw ;-) -- that Bitcoin is a "money" ...
It occurs to me that a blockchain should be able to elect for itself if its a currency or an asset!
If I created a version of Bitcoin that had say a 24-hour target block time and required 7 confirms I doubt anyone would consider it a 'money' or 'currency' if it took a week to spend.
What do you think?
anything can be a 'currency'
EG cigarettes in prison (avoid rape, to get privelidges)
vodka in russia (in exchange for favours such as paying a mechanic as thanks for mending a car)
sexual favours (in many businesses get promotions)
business discounts(electric companies offering free/discounted electric to retailers in exchange for discounts for employee's)
and bitcoin is actually pretty well described as being an asset, and free to be traded as an asset currency.
as for it being FIAT, pfft. well that means that it is a product of government, which bitcoin is not
