How to configure bitcoin core
Recent reports of a false postive virus signature in the block chain and an inappropriate response by Microsoft antivirus software reinforce this point. This guide shows how to install and run Bitcoin Core on a clean Ubuntu Ubuntu does not yet come pre-packaged with Bitcoin Core. Compiling from source offers one option, but involves many steps. A more direct route is to install a precompiled binary from the command line.
The method described here uses Terminal, an application into which text-based commands can be issued. Take a moment to become familiar with how Ubuntu mitigates the risks. This last command may take some time, during which both Bitcoin Core and all of its dependencies will be installed. Prerequisites Ubuntu does not yet come pre-packaged with Bitcoin Core. Searching for the Terminal application. This contains a list of your public keys, they appear as a long string of characters.
Here is the Bitcoin Address public key that Bitcoin Core generated for me: At this point you are ready to accept bitcoin. You can share this address with anyone you want to receive money from. Depending on the sending wallet the transaction will appear instantly or it may take a few minutes. In this case it took about 15 seconds to show up, and a little notification popped up to let me know to check my Bitcoin Core wallet.
The transaction will appear as pending until Bitcoin Miners confirm the transaction. To confirm a transaction, miners have to find a new block which happens roughly every 10 minutes. Most wallets accept a transaction after block confirmations, so the funds are completely available after minutes. Some wallets will let you spend the bitcoins after only 1 confirmation, but it is best practice to wait for at least 3 blocks.
You can track the progress in from the transactions tab. You do not need to leave Bitcoin Core open until the bitcoin is available, miners will confirm the transaction for you even if you close the program.
If you use bitcoin regularly it can be difficult to keep track of your transaction history by seeing only public keys, so you may want to create a new bitcoin address for different purposes and label them. Go back to your receiving addresses and create a new address with a label. You can create as many new addresses as you want. Some people choose to create a new address for every bitcoin transaction. As you can see the transaction comes in labeled instead of the random generated string.
This makes it very easy to accept bitcoin as payment, simply by generating a new labeled address anytime you want to accept bitcoin. You can also see that the first bitcoin transaction has been confirmed and the 0.
If you are a merchant or service provider that is accepting bitcoin, you can use the Request tab to ask for a specific amount of bitcoin. This will generate a QR code that people with a mobile phone wallet can scan to quickly send the desired bitcoin to your wallet. You should use specific information so that later you can look back and know where you got that bitcoin from.
Click request payment and the QR code will be generated. By default it will tell them to send 0. It will generate a QR code that scans directly to a public key. If you save or print out the QR code, you can shutdown your bitcoin core wallet and accept bitcoin anywhere in the world simply by showing people the QR code image. You can check the balance of your bitcoin address from any computer without opening the bitcoin core wallet and verify any bitcoin transaction that you are expecting from somebody simply by knowing the public key.
