In this article, we will explain what is new in Bitcoin Core 0.7.0, the latest version released in September 2012, and how to download, install and use it on your computer.

Introduction

What is Bitcoin Core?

Bitcoin Core is the original software created by Satoshi Nakamoto, the anonymous creator of Bitcoin, in 2008. It was initially called Bitcoin-Qt, and later renamed to Bitcoin Core in 2013 to avoid confusion with the cryptocurrency itself.

Bitcoin Core is an open source project that is maintained by a group of volunteer developers who contribute code, review changes and test new features. Anyone can join the project and suggest improvements or report bugs.

Bitcoin Core has several functions:

• It runs a full node on the Bitcoin network, which means it downloads and stores the entire blockchain (the history of all transactions) and verifies every transaction and block according to the consensus rules.

• It provides a graphical user interface (GUI) that allows users to create and manage their own bitcoin wallets, send and receive bitcoins, view their transaction history and balance, and adjust their settings.

• It also provides a command line interface (CLI) that allows advanced users and developers to interact with the Bitcoin network programmatically, create raw transactions, run scripts, use RPC commands and more.

• It supports mining bitcoins using the CPU or GPU of the computer, although this is not recommended due to the low profitability and high difficulty.

• A new network code that reduced the bandwidth usage by up to 40% and improved the connection stability and security.

• A new wallet encryption feature that allowed users to encrypt their private keys with a passphrase and prevent unauthorized access to their funds.

• A new UPnP (Universal Plug and Play) feature that enabled users to automatically configure their routers to accept incoming connections from other nodes on the network.

• A new bloom filter feature that allowed lightweight clients (such as mobile wallets) to request only relevant transactions from full nodes without compromising their privacy.

A new testnet mode that allowed users to run Bitcoin Core on a separate network for testing purposes without affecting the main network.</. How to Download and Install Bitcoin Core 0.7.0

• You can choose the destination folder where you want to install the software, or use the default one.

• You can also choose whether you want to create a desktop shortcut or a start menu entry for Bitcoin Core.

• You can also choose whether you want to run Bitcoin Core at startup or not.

• The setup will install Bitcoin Core and its dependencies, such as OpenSSL, Berkeley DB, Boost and Qt.

• The setup will also create a data directory where Bitcoin Core will store its configuration files, wallet files and blockchain data.

• The default location of the data directory is C:\Users\YourUserName\AppData\Roaming\Bitcoin, but you can change it by editing the bitcoin.conf file in the data directory.

• The setup will also create a firewall rule that allows Bitcoin Core to communicate with other nodes on the network.

• The installation process may take several minutes, depending on your system specifications and internet speed.

• Once the installation is complete, you can launch Bitcoin Core from the desktop shortcut or the start menu entry.

• You will see a splash screen that shows the version number and the progress of downloading and verifying the blockchain.

• You may also see a warning message that asks you to encrypt your wallet with a passphrase to protect your bitcoins from theft or loss.

• You can choose to encrypt your wallet now or later, but it is highly recommended that you do it as soon as possible.

• To encrypt your wallet, go to Settings > Encrypt Wallet and enter a strong passphrase that you can remember.

• You will need to enter this passphrase every time you want to send bitcoins or access your private keys.

• If you forget or lose your passphrase, you will lose access to your bitcoins forever, so make sure you back up your wallet file regularly.

• To back up your wallet file, go to File > Backup Wallet and save a copy of your wallet.dat file in a secure location, such as a USB drive or a cloud storage service.

• To export your private keys, go to Help > Debug Window > Console and type the command dumpprivkey followed by your bitcoin address.

• You will see your private key in the WIF (Wallet Import Format) which is a base58 encoded string that starts with a 5.

• You can copy this string and save it in a text file or print it on a paper wallet.

• You can also import your private keys to another wallet software or service, but you should only do this if you trust the provider and if you delete the original wallet file afterwards.

• To import your private keys, go to the wallet software or service that you want to use and follow their instructions on how to import private keys.

• You may need to scan a QR code, enter the WIF string or upload the wallet file.
