Cara transfer bitcoin blockchain
You can even use paper storage to avoid having them on a computer at all. Of course, it is very important to secure and back up your bitcoin wallet. Bitcoins are a modern equivalent of cash a nd, every day, another merchant starts accepting them as payment. We know how they are generated and how a bitcoin transaction works, but how are they stored?
What you store are the secure digital keys used to access your public bitcoin addresses and sign transactions. This information is stored in a bitcoin wallet. Bitcoin wallets come in a variety of forms. There are four main types of wallet: Desktop wallets If you have already installed the original bitcoin client Bitcoin-Qt , then you are running a wallet, but may not even know it. In addition to relaying transactions on the network, this software also enables you to create a bitcoin address for sending and receiving the virtual currency, and to store the private key for it.
There are other desktop wallets too, all with different features. Hive is an OSX-based wallet with some unique features, including an app store that connects directly to bitcoin services.
Some desktop wallets are tailored for security: Armory falls into this category. Others focus on anonymity: This is where a mobile wallet comes in handy.
Running as an app on your smartphone, the wallet can store the private keys for your bitcoin addresses, and enable you to pay for things directly with your phone. One common feature of mobile wallets is that they are not full bitcoin clients. A full bitcoin client has to download the entire bitcoin block chain, which is always growing and is multiple gigabytes in size.
That could get you into a heap of trouble with your mobile service provider, who will be only too happy to send you a hefty bill for downloading over a cellular link.
Instead, these mobile clients are often designed with simplified payment verification SPV in mind. They download a very small subset of the block chain, and rely on other, trusted nodes in the bitcoin network to ensure that they have the right information. Examples of mobile wallets include the Android-based Bitcoin wallet, Mycelium, and Blockchain which keeps your bitcoins encrypted on your phone, and backed up on a web-based server. Some have special features unique to them.
Kipochi, for example, lets people use their phone numbers as their bitcoin addresses. Apple is notoriously paranoid about bitcoin wallets. Coinbase had its mobile wallet app pulled from the app store altogether in November , and this was followed in February by removal of Blockchain.
However, the new as of spring app Bity provides a simple service that links to your wallet hosted elsewhere, and lets you accept and make payments via QR code scans or manual entry of wallet keys. We have had no reports as to the quality of this app yet, so stop short of a recommendation until we have more information. Furthermore, you can still manage bitcoin accounts using a browser on the iPhone, and CoinPunk are developing such a browser-based solution, which Apple cannot ban.
Online wallets Web-based wallets store your private keys online, on a computer controlled by someone else and connected to the Internet.
Several such online services are available, and some of them link to mobile and desktop wallets, replicating your addresses between different devices that you own. One advantage of web-based wallets is that you can access them from anywhere, regardless of which device you are using.
However, they also have one major disadvantage: Blockchain also hosts a popular web-based wallet, and Strongcoin offers what it calls a hybrid wallet, which lets you encrypt your private address keys before sending them to its servers — encryption is carried out in the browser.
