i had an idea that if I were a US bank I would create a USD token on Ethereum that would be redeemable at my bank (or my network of banks). A eUSD token would created via smart contract and be pegged to the dollar and thereby tradable on the Ethereum network. Individuals and business could then do business in USD (or any fiat of choice for that matter. Obtainable on an Ethereum exchange or through said bank(s)). Other implications: An accounting firm could create a smart contract that calculates and or files my taxes. A business structure (LLC, IPO etc) in can be written into a smart contract. And so on.

Ah, the magic trustless dollar-pegged digital token. Many tales have been spoken of them, but none stand up to close scrutiny. You need to solve this problem before basing anything else upon it.
