Bitcoins have all the desirable properties of a money-like good. They are portable, durable, divisible, recognizable, fungible, scarce and difficult to counterfeit. Bitcoin can also be a store of value , some have said it is a "swiss bank account in your pocket". Bitcoin is a peer-to-peer currency.

Peer-to-peer means that no central authority issues new money or tracks transactions. These tasks are managed collectively by the network. Bitcoin uses public-key cryptography , peer-to-peer networking, and proof-of-work to process and verify payments. Bitcoins are sent or signed over from one address to another with each user potentially having many, many addresses. Each payment transaction is broadcast to the network and included in the blockchain so that the included bitcoins cannot be spent twice.

After an hour or two, each transaction is locked in time by the massive amount of processing power that continues to extend the blockchain. Using these techniques, Bitcoin provides a fast and extremely reliable payment network that anyone can use. Create a wiki account and get it activated. Jump to: navigation , search.

Bitcoin is P2P electronic cash that is valuable over legacy systems because of the monetary autonomy it brings to its users. Bitcoin seeks to address the root problem with conventional currency: all the trust that's required to make it work -- Not that justified trust is a bad thing, but trust makes systems brittle, opaque, and costly to operate.

Trust failures result in systemic collapses, trust curation creates inequality and monopoly lock-in, and naturally arising trust choke-points can be abused to deny access to due process. Through the use of cryptographic proof, decentralized networks and open source software Bitcoin minimizes and replaces these trust costs. Bitcoin Transactions are: Permissionless and borderless.

The software can be installed by anybody worldwide. Bitcoin does not require any ID to use making it suitable for the unbanked, the privacy-conscious, computers or people in areas with underdeveloped financial infrastructure. When used with care bitcoin can support strong financial privacy. Nobody is able to block or freeze a transaction of any amount.

Transactions can be made almost as fast as data can travel over the Internet. Fees can be very very low. Irreversible once settled, like cash. Online and available 24 hours a day, days per year. Stored Bitcoins: Cannot be printed or debased. Bank transfers are the most popular mode of payment. The use and trade of Bitcoin is legal in the majority of countries in the world, however, because it is a deregulated marketplace, governments are concerned about its potential threat as a tool for money laundering.

Although mining and exchanging are questionable in terms of legality, it is known to be legal for users who exchanges bitcoins for goods and services. Using a blockchain ensures security and manages digital relationships as part of a system of record.

A distributed ledger is a database, digitally recording transaction information using cryptography, making it secure and unforgeable. There are several differences between a blockchain and a database, including the level of control. Blockchains are under a decentralized control, whereas a centralized database creates a dependent relationship between users and administrators. Users tend to prefer confidentiality, which is better achieved through a centralized database. Performance also differs, as a centralized database is able to compute information faster than blockchains.

Given that Bitcoin was the first cryptocurrency to surface in the market, the other digital currencies that emerged are referred to as altcoins. Make Kitco Your Homepage. Login Sign Up Refresh Page.
