Wallet types and functions from "summary" of The Basics of Bitcoins and Blockchains by Antony Lewis
When it comes to storing your bitcoins and other cryptocurrencies, you will need a digital wallet. Just like a physical wallet that holds your cash and cards, a digital wallet is a software program that allows you to store, send, and receive cryptocurrencies. There are different types of wallets that cater to various needs and preferences. The first type of wallet is a software wallet, which is a program that you install on your computer or smartphone. This type of wallet gives you full control over your private keys, which are needed to access your cryptocurrencies. Software wallets can be further categorized into desktop wallets, mobile wallets, and web wallets, each with its own advantages and drawbacks. Another type of wallet is a hardware wallet, which is a physical device that stores your private keys offline. Hardware wallets are considered more secure than software wallets because they are not connected to the internet, making them less susceptible to hacking. However, hardware wallets can be more expensive and less convenient to use compared to software wallets. There are also paper wallets, which are physical documents that contain your private and public keys. Paper wallets are immune to hacking and malware attacks since they are offline. However, paper wallets can be easily lost or damaged, and they require careful handling to ensure the security of your cryptocurrencies. Lastly, there are also multi-signature wallets, which require multiple private keys to authorize transactions. This type of wallet is often used by businesses and organizations to enhance security and prevent fraud. Multi-signature wallets can be set up with different combinations of private keys, depending on the desired level of security. In addition to storing your cryptocurrencies, wallets also allow you to send and receive payments. When you want to receive bitcoins, you simply provide the sender with your public key, which is like your account number. When you want to send bitcoins, you sign the transaction with your private key to authorize the transfer.- Choosing the right wallet is crucial to ensuring the security and accessibility of your cryptocurrencies. Whether you opt for a software wallet, hardware wallet, paper wallet, or multi-signature wallet, it is essential to understand the functions and features of each type to make an informed decision.
