The significant motivation behind cash is to track obligation. Actually, the obligation following nature of cash existed generally before the innovation of the principal coin. The sanctuaries of the antiquated close east used to be accountable for following and recording every one of the obligations of their close-by territories. Coins were later imagined to disentangle the organization of the rising iron age realms, who would not like to manage every sanctuary's interesting strategy for recording and taking care of obligation.
Bitcoin does not track obligation well, it is a coin. I owe you 100 piece coins and you owe fred 80 bit coins, and there are just 100 piece coins in the whole world, at that point this obligation data must be dealt with outside the square chain.
This influences me to imagine that bitcoin will never supplant the managing an account framework.
Nice remark but look at ideas like bitshares with lending, obligations etc. An obligation is just a smart contract i would say...
