What is a Blockchain Wallet?
First of all, you need to keep in mind that ownership of cryptocurrency is different from ownership of the traditional currency. Cryptocurrency is not available in the physical form and is considered a group of codes.
In reality, crypto wallets don’t store the currency but act as a tool of interaction with blockchain, i.e., generating the necessary information to receive and send money via blockchain transactions.
A blockchain wallet is a cryptocurrency wallet that allows users to manage different kinds of cryptocurrencies—for example, Bitcoin or Ethereum. A blockchain wallet helps someone exchange funds easily. Transactions are secure, as they are cryptographically signed. The wallet is accessible from web devices, including mobile ones, and the privacy and identity of the user are maintained.
How Do Blockchain Wallets Work?
A crypto wallet is used to interact with a blockchain network. With a wallet, a user is able to view and manage their cryptocurrency, as well as initiate transactions. They exist in many forms, from easy-to-use online web wallets offered by leading crypto exchanges to more technically complex and secure offline, hardware-based wallets.
What all wallets have in common are keys, which are needed to access a user’s crypto assets. When a wallet is created, a pair of keys are generated, one public and one private. These lengthy alphanumeric sequences may appear similar, but their functions are drastically different.
A public key works like a bank account number; it can be shared with anybody who wants to send you cryptocurrency, much like how an account number appears at the bottom of a paper check. A private key, on the other hand, can be thought of as your bank account’s PIN code and should be carefully safeguarded. Anyone who has access to that private key will have complete control over your crypto holdings.
When a user wants to send cryptocurrency, they input the receiver wallet’s public key and the amount of crypto they want to send. The process is reversed when a user wants to receive crypto. Anytime cryptocurrency moves out of a wallet, the transaction must be “signed” using the private key. How that crucial step happens depends on the type of wallet you use.
Cold Wallets vs Hot Wallets
Internet connectivity defines a wallet in terms of hot or cold. Hot wallets are connected to the Internet and thus are less secure and pose more risks but are user-friendly. Cold wallets, on the other hand, are stored offline and don’t require internet connectivity.
A hot wallet simply means any crypto wallet that is connected to the internet. They’re easy to use, so most types of crypto wallets are of the “hot” variety. But they are more vulnerable to hackers. Because of this, it is not recommended to keep large amounts of cryptocurrency in a hot wallet.
Cold wallets are the type of wallet that is offline, or not connected to the internet. Since the only way to interact with the blockchain is through the internet, cold wallets are considered highly secure and virtually impervious to hacking. Cold wallets tend to require a bit more technical know-how, so they’re typically suited for more experienced users or those with large amounts of assets.
Hot wallets are basically the wallets that connect to the internet and generally offer lesser security. Hot wallets offer better accessibility due to their connection to the internet. They are highly user-friendly. There are several different types of hot wallets available, each with potential benefits and drawbacks depending on needs.
These are installable software packs available for operating systems. Desktop wallets utilize encryption to keep a user’s private keys securely stored on their computer hard drive.
These wallets are accessed by internet browsers. Web wallets are wallets provided by a third party, typically a crypto exchange, which offer seamless access to a user’s holdings using a web browser.
Mobile wallets allow users to quickly and securely send or receive cryptocurrency with their phone and an active internet connection.
The two most popular types of cold wallets are hardware and paper. Both are considered a highly secure way of securing your crypto.

Hardware wallets are hardware devices that individually handle public addresses and keys. It cost up to 70-150 dollars, but it is worth it. It is a battery-less device and can be connected to a PC and accessed by native desktop apps. The most popular hardware wallets are Ledger Nano S and Trezor.
