Hello. I'm trying to figure out a short way to describe bitcoin to laypeople in a document. So far I've got this. What do people think? And are there any ideas for good descriptions?...
Bitcoin is a decentralised electronic currency which is not backed by any other currency as it is a stand-alone currency traded against other currencies.
Bitcoins are traded using a peer-to-peer decentralised network over the internet. Bitcoin does not rely upon banks or clearing houses; instead the electronic transactions are guaranteed mathematically without needing trust in a third party.
This works because the bitcoin software stores secret keys which allow people to access their money and nobody else. People can send bitcoins to each other using bitcoin addresses. Bitcoin addresses are analogous to bank account numbers, such that money can be sent to them.
Bitcoin uses a proof-of-work system to prevent people from spending the same money several times. Transactions are stored alongside proof that a required level of work was completed to store these transactions. This required work makes it practically impossible to reverse transactions and spend the same money more than once.
People who do this work are referred to as “miners”. These miners receive newly generated bitcoins as a reward for processing transactions, hence this activity is described as “mining bitcoins”. The reward miners receive will go down over time because the amount of total bitcoins created will never exceed 21 million, but miners also receive transaction fees included in transactions which provides an additional incentive to process transactions.
Below is a graph showing the total amount of bitcoins created over time which the software is designed to follow:
Bitcoins can be generated or “mined” by anyone with the appropriate computer software, but to trade bitcoins people do not need to mine them; instead people can buy bitcoins online or trade goods or services in exchange for them. Then people can proceed to make purchases in bitcoins using various computer applications or web-apps. These applications provide bitcoin "wallets" and addresses which allow people to send and receive bitcoins. "wallet" is a term which is used to refer to the place where bitcoins are accessed. It may be easy to think of a bitcoin wallet as being like a bank account.
The key benefits to using bitcoin are:
* There is no third party risk because people own their bitcoins directly through the secret keys.
* Transactions are irreversible (No chargebacks).
* Transactions are typically free at the present time.
* Nobody has to share sensitive financial details unlike with credit/debit card payments.
* Bitcoin creation is limited and predictable.
* Payments can be made globally over the internet.
