Gur Huberman (Columbian Business School) “An Economic Analysis of the Bitcoin Payment System”
Abstract : Although radically different from a traditional payment system, Bitcoin is functional and transmits value over the internet. Having fixed transaction processing capacity, it experiences service delays which motivate users to pay for service priority. These fees fund the computer servers (“miners”) which support Bitcoin. This paper models Bitcoin as a platform that intermediates between users and miners. It derives closed form formulas of the fees and waiting times and studies their properties; compares the economics of the Bitcoin payment system (BPS) to that of a traditional payment system operated by a profit maximizing firm; and suggests protocol design modification to enhance the platform’s efficiency. The appendix describes and explains the main attributes of Bitcoin and the underlying blockchain technology.
