> While this view of Bitcoin might sound like it is a betrayal of Bitcoin's original vision of fully peer‐to‐peer cash, it is not a new vision. Hal Finney, the recipient of the first Bitcoin transaction from Nakamoto, wrote this on the Bitcoin forum in 2010: Actually there is a very good reason for Bitcoin‐backed banks to exist, issuing their own digital cash currency, redeemable for bitcoins. Bitcoin itself cannot scale to have every single financial transaction in the world be broadcast to everyone and included in the block chain. There needs to be a secondary level of payment systems which is lighter weight and more efficient. Likewise, the time needed for Bitcoin transactions to finalize will be impractical for medium to large value purchases. Bitcoin backed banks will solve these problems. They can work like banks did before nationalization of currency. Different banks can have different policies, some more aggressive, some more conservative. Some would be fractional reserve while others may be 100% Bitcoin backed. Interest rates may vary. Cash from some banks may trade at a discount to that from others. George Selgin has worked out the theory of competitive free banking in detail, and he argues that such a system would be stable, inflation resistant and self‐regulating.
