What Is a Cold Wallet?

A cold wallet works offline to store bitcoins and other cryptocurrency. With a cold wallet, often referred to in the past as cold storage the digital wallet is stored on a system that isn’t accessible to Internet, thereby shielding the wallet from unauthorised access, cyber hacks, and other vulnerabilities that a system connected to the internet is vulnerable to.

These methods of storage are great for individuals who invest, however, cryptocurrency exchanges and companies involved in the crypto industry also make use of this type of wallet. Cold storage can also refer more broadly to other types of storage methods for non-active data such as documents for regulatory compliance, video, photographs and backup information.

Principal Takeaways

The majority of cryptocurrency wallets are digital but hackers can sometimes be able to access these storage devices despite security measures designed to guard against the theft.
Cold wallets are a method to hold cryptocurrency tokens on a separate account.
By using a cold wallet the cryptocurrency owners aim to prevent thieves from being in a position to access their funds through traditional means.

Why do you need the Cold Wallet?

When a savings, checking and credit card account linked to the traditional bank is compromised, the bank is in a position to pay the lost or stolen money back to the account owner. However, if your crypto account or wallet is compromised and your coins have been taken, the account owner is not able to retrieve their money. The reason for this is that the majority of digital currencies aren’t centralized and don’t have the support of a central bank or government. Thus, cryptocurrency investors need to be cognizant about the measures required to safeguard their crypto tokens. This is why there is a need for a secure and secure medium to store bitcoins and altcoins.

A bitcoin wallet is associated with the private and public keys of the bitcoin owner. All storage options for cryptocurrency require the protection of these keys because they grant access to funds in the wallet. A cryptocurrency owner’s private key is a distinct string of alphanumeric characters that is required for access to the crypto assets for the purpose of spending. The public key can be compared to a name for an account or an email address. It helps identify the location of the coins being transferred through the bank account.

Two individuals who make a purchase using a cryptocurrency such as bitcoin, in which one is both a seller and buyers, will need to share their public keys with one another for the purpose of completing the transaction. The purchaser of the product or service transfers the required amount of bitcoins seller’s disclosed address for payment, and the blockchain confirms the authenticity of the transaction and proves that the seller really has the money to make the payment. When the payment has been transferred to the address, the receiver is able to gain access to the funds via their private keys. Therefore, it is important that private keys be secured because in the event of theft, bitcoins or altcoins could become stolen and used to access your address, without authorisation.

Cold vs. Hot Wallets What’s the difference?

There are a variety of methods for keeping cryptocurrencies. In addition to cold storage, one of the other most well-known methods is described as “hot storage.” Hot wallets are those that are always connected to the internet, such as the wallet app and the wallets supplied through cryptocurrency exchanges. What are the benefits of cold vs. hot storage for cryptocurrency?

Cost: When it comes to cost, hot wallets generally beat out other wallets. Most of the hot wallets are cost-free. Cold wallet options range between free (in an instance of paper wallet as explained below) to up to $100 to $200 for various types of hardware wallets.
Experience of the user: Since they are already connected to the internet, hot wallets tend to be the most convenient to users. There is no further step of connecting the account online to make it easier for users to transfer tokens.
Security: The main reason cold wallets enjoy advantages against hot ones is in security. Hot wallets are very secured, due to various security measures for cryptography. However, they’re not as secure as the security of cold wallets in general.

To address the problem of deciding between a hot and cold wallet for storage method, many cryptocurrency investors utilize both. It is normal to store just a portion of your cryptocurrency tokens in a hot wallet , to facilitate easy transactions, as well as to store the portion of your assets in a safe cold wallet.

What Can Cold Wallets Prevent Theft?

Private keys that are stored in a wallet connected to the internet are vulnerable to the theft of data via networks. With a hot wallet, all functions needed for completing a transaction can be done by a single online device. The wallet generates and keeps private keys, and digitally authenticates transactions with private keys, and then broadcasts transactions that have been signed to the network.

The issue is that, once the transactions signed by the parties have been posted online, a hacker who is scouting the networks could become aware of the private key used to sign the transaction.

How Does Cold Storage Work?

Cold storage resolves this issue by signing the transaction with the private keys in an offline setting. A cold storage method shouldn’t be able to communicate with other electronic devices except if it’s physically connected into the device that you are accessing the keys.

The transaction is temporarily transferred to an offline wallet kept on a device like an USB drive, compact disk (CD) or paper, hard drive or an offline computer. There, it is digitally signed before being sent to an online network. Because the private key will not connect to any online servers during the process of signing in the event that an online hacker discovers this transaction will not have access to the private key used for the transaction. In exchange for this added security, the process of transferring into and out of a cold-wallet device can be a bit more difficult than that of hot wallets.

As an example, if you are a crypto-investor and have tokens in a physical wallet (see below for more details) an exchange of cryptocurrency to receive new tokens might be like this:

The user connects the physical wallet of the device with an internet-enabled computer.
The investor chooses for receiving tokens. The device creates an address that facilitates the transaction.
The sender initiates a transfer of tokens to the address generated above.
The buyer disconnects the hardware wallet, which contains the public and private keys. The information remains inaccessible.

Paper Wallets

The most basic kind that cold storage can be found is in a paper wallet. A paper wallet is simply the name of a document with public and private keys written on it. If it is the bitcoin paper wallet a bitcoin holder can print the document using the bitcoin paper wallet online tool with an offline printer. The paper wallet or document usually has a quick response (QR) codes embedded in it , allowing it to be easily scanned and signed in order to conduct a transaction.

The drawback of this option is that if the wallet is lost, rendered unreadable or destroyed, the user is not able to access the account that holds their funds. If you decide to use this method, be sure to keep a safe container or a secure storage solution for the paper wallet.

Hardware Wallets

Another kind that cold storage can be a hardware wallet that utilizes an alternative device, such as a smartcard, to generate public keys in offline. The Ledger USB Wallet is an example of hardware wallets that use smartcards to secure private keys. Other popular hardware wallets include TREZOR as well as KeepKey. The device appears and works similar to it’s a USB drive. A computer and an app that runs on Chrome are needed to save the private keys in a secure, offline location. You can choose anything from a standard USB storage drive to a more advanced one that comes with a battery Bluetooth, software, and other features. Similar to a paper wallet it is essential to store the USB devices and smartcards in a secure place, as any damage or loss could result in the denial of access to user’s bitcoins.

Air-gapped devices do not have a connectivity capabilities and are less secure than devices that connect wirelessly. You can buy physical wallets that are commercially available from retailers and retailers; many are waterproof and virus-proof. A few allow multiple-signature (“multi-sig”) transactions. Multi-signature is a signature for cryptocurrency method with more than one person to authorize a transaction using private keys.

Sound Wallets

Sound wallets can be a mysterious and expensive way to store your keys, contingent on your chosen medium. Sound wallets require encryption while recording the keys of private individuals on sound files that are stored on products such as CDs or vinyl disks (records). The code contained in these audio files can be deciphered using a spectroscope or high-resolution spectroscope.

Deep Cold Storage

Inscribing your hardware wallet into your safe is secure however it’s not considered to be deep cold storage as it’s simple for you to access. Deep cold storage refers to any technique that is unpractical and requires time and effort to retrieve your keys. This could include placing your hardware wallet into an outdoor container that is waterproof and then burying it 6 feet deep in your backyard, to using a third party service which stores your crypto keys in a vault which requires numerous steps to access.

In the garden, burying your keys into the garden is not without its disadvantages which include lots of digging and having to remember where you buried them at the time, but neither does the vault service that is ultra-secure. Vault services generally require identity as well as proof of address or some other proof of identity. In addition, it could take a few hours or days to get access to your keys depending on the location where they’re physically stored.

Funds held in cryptocurrency in deep cold storage aren’t readily accessible for transactions.

Offline Software Wallets

Additionally, those looking for cold storage options may also consider offline software wallets. They are similar to hardware wallets, but are a more difficult process for novice users. An offline software wallet splits a wallet into two accessible platforms: an offline wallet which contains private keys as well as an online wallet with the public keys stored. The online wallet creates new transactions that are not signed and forwards the address and details for the customer to the receiver or the sender at the other end of the transaction. The unsigned transaction gets moved to an offline wallet, and then signed using the private key. The transaction that has been signed is transferred back to the online wallet, which broadcasts the transaction to the network. Since the offline wallet does not get hooked up to the web, its private keys are secure. Electrum as well as Armory are often quoted as the best offline software wallets available in the crypto economy.

Cryptocurrency users should ensure that the wallet they choose is compatible with the coins they trade in, as there are not all wallets that support all currencies.

However, Coinbase provides a vault to all customers, which is able to store private keys and keep them in a secure offline location. Institutions can use the exchange provides cold storage via Coinbase Custody, a third-party fiduciary with offline storage.

Why Do We Need Cold Wallets?

Cold wallets are ways to keep cryptocurrency tokens in a safe place to block cybercriminals from being in a position access the accounts of the owner using traditional internet-hacking means.

How Does a Hot Wallet compare to a Cold Wallet?

They are typically completely free, meaning they cost less than cold ones however, they provide less protection against theft and unauthorized use than cold wallets. Since they’re already connected to the internet hot wallets are able to be the most convenient option for usersas there’s no extra step to connect the wallet online in order to transfer tokens.
