take so long? Attempting to assign special rights to a local authority in the rules of the global Bitcoin network is not a practical possibility. Investing time and resources on anything related to Bitcoin requires entrepreneurship. The Bitcoin protocol is designed in such a way that new bitcoins are created at a fixed rate. Mining is the process of spending computing power to process transactions, secure the network, and keep everyone in the system synchronized together. Every user is free to determine at what point they consider a transaction sufficiently confirmed, but 6 confirmations is often considered to be as safe as waiting 6 months on a credit card transaction. Bitcoin payments can be made without personal information tied to the transaction.
The answer is nothing at all, but thats actually not a bad thing.
Like most modern currencies bitcoin is not backed by gold or other precious commodities.
In fact, bitcoin is backed by peoples belief in it as a convenient, effective and fair means.
If the fact that Bitcoin is backed by the market and consequently by people, does not seem compelling. But what is Bitcoin backed up by? The answer seems to be nothing : there. Let us examine what is meant by the statement the US dollar, up until the latter half of the 20th century, was backed by gold.
Bitcoins are not actually received by the software on your computer, they are appended to a public ledger that is shared between all the devices on the network. What happens when bitcoins are lost? Bitcoin is a free software project with no central authority. Choices based on individual human action by hundreds of thousands of market participants is the cause for bitcoin's price to fluctuate as the market seeks price discovery. It can be perceived like the Bitcoin data center except that it has been designed to be fully decentralized with miners operating in all countries and no individual having control over the network. This ledger contains every transaction ever processed, allowing a user's computer to verify the validity of each transaction. Technically speaking, synchronizing is the process of downloading and verifying all previous Bitcoin transactions on the network. For new transactions to be confirmed, they need to be included in a block along with a mathematical proof of work.
