Cryptocurrency wallets store secret keys used to digitally sign transactions for blockchain distributed ledgers, but their future goes far beyond being just a keeper of cryptocurrencies. They could one day represent your professional and financial status or even your personal identity.
A cryptocurrency wallet is a piece of software that keeps track of the hidden keys used by distributed ledgers to digitally sign cryptocurrency transactions. Because those keys are the only way to prove ownership of digital assets – and execute transactions that transfer them or in some way change them – they are a critical piece of the cryptocurrency ecosystem.
Better named “crypto wallets,” they are like blockchain car keys. The car does not work without those keys. And without them, there would be no way to show ownership of a digital asset-anything from a bitcoin to a token representing some sort of assetBetter named “crypto wallets,” they are like blockchain car keys.

What do crypto wallets do?
In addition to keeping track of encryption keys used to digitally sign transactions, a crypto wallet (or, more commonly, a digital wallet) often stores the address on a blockchain where a specific asset resides. When the owner loses that address, they will effectively lose control of their digital money or other assets according to David Huseby, security maven Linux Foundation ‘s Hyperledger Project.
Here are two main types of crypto-wallets: hardware and software (also known as cold wallets and hot wallets). Hot storage wallets are available via an internet provider such as Coinbase, one of the largest cryptocurrency exchanges providing online wallets to customers, and can be further divided into online wallets and customer-side wallets operated locally on a user’s mobile or computer.
There are also generators of paper wallets, which generate keys which can be printed out or made as QR codes.

Cold storage wallets are downloaded on a piece of hardware such as a USB drive or smartphone and reside offline. Exodus.io and Dash QT are two examples of the software for cold storage wallets. Cold storage wallets can also be bought as devices that already have the software installed on them; retailers such as Trezor and Ledger offer these kinds of devices.
Furthermore, hardware wallets can be divided into crypto assist type wallets that simply handle the keys and sign arbitrary data and are sometimes referred to as hardware security modules (HSMs). “And then there are hardware wallets that handle complete transactions that are generated and signed and then sent to the distributed ledger network,” Huseby said.
When you connect with the blockchain, the hardware can connect on the computer through the codes. Nonetheless, according to Gartner Vice President of Research Avivah Litan it is not a really nice user interface.
Hot and cold wallets – which is more secure?
Gartner recommends converting cryptocurrency to fiat money – cold hard cash, as in real dollars , euros, yen or some other currency – for safekeeping, or storing crypto keys in a cold wallet. Then the latter means making a paper copy of the keys and putting the document in a safe place like a bank security deposit box.
Paper can also be used through software as a type of wallet that creates a QR code that can be scanned to enable blockchain transactions. Otherwise, Gartner recommends using an online exchange with a wallet service that uses push technology to enforce two-factor authentication. Push technology connects the second factor to a cell phone registered;so that only an owner’s phone can approve an access request pushed out by the exchange wallet’s authentication service.
