What is Cryptocurrency Hardware Wallet ?

Crypto Hardware Wallets

This is the safest way to keep Bitcoins and other cryptocurrencies? Can they be hacked? What happens if my hardware wallet is lost? Are my coins gone forever?

Before we go into hardware wallets, it's important to understand how any Bitcoin wallet works. The phrase "Bitcoin wallet" is a misnomer because a Bitcoin wallet does not really store Bitcoin. A Bitcoin wallet is a piece of software that stores passwords, which are sometimes referred to as keys in cryptography. These keys give your wallet access to the Bitcoins it has been given on the blockchain, which is a public record of all Bitcoin transactions.

When using any Bitcoin wallet, you'll come across two key phrases. The first is a Bitcoin address, which is similar to an email address and is what you provide to those who wish to pay you in Bitcoin. A private key is the second. The private key gives you access to and control over your bitcoins. In our email account analogy, consider your private key to be the password to your email account. The wallet not only stores your private key, but it also signs Bitcoin transactions on your behalf and broadcasts them to the Bitcoin network.

When you wish to transmit Bitcoins to someone else, you must show the whole network that you hold those Bitcoins before it will agree to update the transaction ledger. Your Bitcoin wallet does this by taking your requested transaction, signing it on your behalf with your private key, and broadcasting this digital signature to the network. In a nutshell, a digital signature allows you to verify ownership of a private key without having to reveal it. Cryptography, a set of complicated mathematical principles, is used to accomplish this.

This procedure is comparable to signing a cheque allowing the withdrawal of funds from your account. The wallet then broadcasts the transaction to the whole network, which verifies its legitimacy. Bitcoin miners will eventually add this transaction into the blockchain, and the transaction will be declared complete. So, how does any of this relate to hardware wallets? If my wallet is just a piece of software, why can't I keep it on my computer alongside the rest of my software? As you surely know, stealing data from a computer isn't all that difficult these days. If the machine that runs your Bitcoin wallet is attacked by malware, your private key might be exposed to malicious actors.

Hackers may be able to get access to your computer or view what's on your screen. And once your private key is revealed, you lose control of your bitcoins. They could be easily moved to wherever the hacker desires. You have two alternatives for avoiding this situation: First and foremost, make certain that your computer is malware-free. While this may appear to be a simple task, most viruses are either camouflaged as genuine software or have a method of evading detection by antivirus software.

Another approach is to utilize a wallet that is "immune" to viruses, therefore protecting your private key. This is precisely what hardware wallets are intended to accomplish. Simply defined, hardware wallets are computers with no logic other than a small screen, a few buttons, and the sole function of storing keys and signing transactions. Hardware wallets resemble miniature USB flash drives and use a simple approach to security.

This is predicated on the idea that the more complicated a technology is, the more chances hackers have to break into it. In the case of hardware wallets, the gadget is so "stupid" that hacking or infecting it is nearly impossible. Hardware wallets cannot connect to the Internet or operate complex programs due to their simplistic nature. They're merely a way to keep your private key off the internet. This method is known as "cold storage," as opposed to "hot wallets," which are devices that connect to the Internet. So, how exactly do hardware wallets work? Let's imagine you wish to use a hardware wallet to send a Bitcoin transaction.

The first thing to understand is that, because a hardware wallet can only sign transactions, it must rely on a more powerful computer to perform all other tasks, including preparing the transaction and broadcasting it to the network. To utilize a hardware wallet, you must first connect it to your computer and then download a software program that can communicate with it. This software will be known as a bridge. You can use the bridge to arrange your transaction for signing. Only extremely restricted sorts of data, such as bitcoin transactions, are allowed to transit via the hardware wallet. It takes transactions from the bridge software, signs them on the hardware wallet, and then transmits them back to the bridge program.

Your private key is never sent outside of the hardware wallet. Only the unsigned and signed transactions are sent between your computer and the hardware wallet. A hardware wallet may be used with any computer without risk of being hacked or infected due to its basic and simple design - even a public library computer or your mother's laptop:) The only thing you'll need to do to ensure the safety of your Bitcoins is to double-check that the transaction you're authorizing on the hardware wallet's screen matches the transaction your bridge application is showing on your computer. Hardware wallets are now available from over a dozen businesses, with the three industry leaders being Ledger, TREZOR, and KeepKey.

Each company offers different models with different features. If you’d like to read all about the different models on our site, there’s a link in the description below. There are many features to compare between the different hardware wallets. Some things to consider, aside from the company's reputation, include how many different coins the device can support and whether you can control it from your mobile phone as well as from your computer. Setting up a hardware wallet is fairly easy. The main thing to do is write down the set of words you’ll be given when initializing the device.

Each firm provides a variety of models with various characteristics. There's a link in the description below if you want to learn more about the many models on our site. There are several factors to consider when comparing hardware wallets. Apart from the company's reputation, you should think about how many different currencies the device can support and whether you can operate it from your phone as well as your computer. A hardware wallet is simple to set up. The most important thing to remember is to write down the set of words you'll be given when you first turn on the gadget.

These words, also known as a seed phrase or mnemonic phrase, can be used to recover any private key generated by your hardware wallet. This also implies that whomever obtains these words will have complete authority over your Bitcoin. Therefore, keep your seed phrase written down and stored safely. Before we wrap off today's session, I'd want to go through some common hardware wallet concerns and how to prevent them wherever possible. The first danger is that your equipment may be tampered with on its way to your house for the first time. To get around this, all reputable companies that make hardware wallets put a holographic label on the wallet that shows it has never been opened.

If this sticker is missing from your wallet, don't use it. While some wallets do a self-tampering test when they first start up, it's best to be careful. Always purchase a hardware wallet directly from the manufacturer's website to further reduce this danger. If you wish to buy from a reseller, contact the manufacturer first to ensure that he is an authorized and trustworthy reseller. This problem is related to the fact that your seed phrase should be made at random by your wallet when you set it up and not given to you with the device.

There's a strong reason to take all of these precautions seriously. One unlucky customer, for example, purchased a hardware wallet from a rogue seller on Amazon and received a wallet with a card holding a preloaded seed word. He was told to use this existing seed phrase to start the gadget. The consumer was not particularly tech-aware and followed the instructions, only to discover that after he transferred funds into the hardware wallet, the hacker who knew the preset seed immediately deleted them. Evil maid attacks are another risk you should be aware of. In these attacks, your hardware wallet device is stolen or hacked by people who shouldn't have access to it.

PIN protection is included in most, if not all, hardware wallets nowadays. Even if your gadget is taken, it may take a long time for the criminal to have access to your coins. If your device is taken, you should use your seed phrase to retrieve your bitcoins and transmit them to a new wallet with a different seed phrase as soon as possible. This effectively drains your stolen wallet of any cash, allowing you to maintain secure control over your Bitcoins. The "$5 wrench assault" is another uncommon but conceivable attack. If you don't hand up your hardware wallet and open it with your PIN code, someone will physically threaten to injure you with a $5 wrench. Certain wallets, such as TREZOR, allow you to add an additional layer of protection called a pass to guard against these types of physical attacks. This implies you'll be asked to enter another passcode following the PIN code.

You may, however, configure it such that various passes only display particular accounts in your wallet. Assume you have a fake wallet account with a modest quantity of coins and a genuine wallet account with the rest of your assets. When someone compels you to unlock your wallet, you may use the fake card to make it appear that the wallet only has a tiny quantity of money, preventing your whole holdings from being revealed. What happens if the wallet maker goes out of business? This is a typical concern people have about hardware wallets.

The seed phrase technology used in most hardware wallets today is cross-platform and not exclusive to any one firm. As a result, if a firm goes out of business, you can reclaim your bitcoins by entering your seed phrase into another company's wallet. As you surely know, your seed phrase is quite powerful, and it may be used to retrieve your bitcoins in a variety of situations, including if your hardware wallet is lost or destroyed. That concludes today's Crypto Whiteboard Tuesday episode. Hopefully, you've figured out what a hardware wallet is. A tiny gadget that protects your bitcoins by storing your private keys and signing transactions offline. You could still have some concerns.
