I was thinking about the future of BTC and I wonder if its near-term utility will be as an irreversible medium of transfer. Basically a replacement for the wire transfer.
That's what
DigiCash. DigiCash, invented by David Chaum, was the predecessor of Bitcoin. Chaum solved the double-spending problem and the change problem, which Bitcoin copies. Bitcoin adds mining and miners as guarantors of the block chain. DigiCash was centralized. Because it was centralized, DigiCash could use existing currencies. The central service would convert anonymous DigiCash to and from some other currency at fixed rates.
DigiCash almost made it big, but Chaum blew deals with Goldman Sachs, ING, and Microsoft. One source says that Microsoft wanted to put DigiCash in Windows 95. They were thinking micropayments; a way to send a few cents or dollars cheaply.
