'How I lost £25,000 when my cryptocurrency was stolen'
A cryptocurrency wallet is a piece of software that keeps track of the secret keys used to digitally sign cryptocurrency transactions for distributed ledgers. Because those keys are the only way to prove ownership of digital assets — and to execute transactions that transfer them or change them in some way — they are a critical piece of the cryptocurrency ecosystem.
Better known as "crypto wallets," they are like the keys to the blockchain car. Without those keys, the car won't run.
And without them, there would be no way to prove ownership of a digital asset - anything from a bitcoin to a token representing some kind of asset.
Not only does a crypto wallet or more generically, a digital wallet keep track of encryption keys used to digitally sign transactions, it also stores the address on a blockchain where a particular asset resides. If the owner loses that address, they essentially lose control over their digital money or other asset, according to David Huseby, security maven for the Linux Foundation's Hyperledger Project.
There are two main types of crypto wallets: hardware and software also known as cold and hot storage wallets, respectively. Hot storage wallets are accessible via an internet service such as Coinbase , one of the largest cryptocurrency exchanges that supplies online wallets for users, and can be further segregated into online wallets and client-side wallets managed locally on a user's computer or mobile device. There are also paper wallet generators , which create keys that can be printed out or rendered as QR codes.
Cold storage wallets are downloaded and reside offline on a piece of hardware such as a USB drive or a smartphone. Cold storage wallets can also be purchased as devices with the software already installed on them; these kinds of devices are sold by vendors such as Trezor and Ledger. Hardware wallets can be further divided into crypto-assist type wallets that simply handle the keys and signing of arbitrary data and are sometimes called hardware security modules HSMs.
When you communicate with the blockchain, the hardware communicates through the codes on the device. A cold storage wallet is innately more secure than a hot wallet because it's not connected to the internet. Most cryptocurrency attacks have occurred when a hacker hits an online wallet service and transfers the secret keys to their own wallet — essentially transferring the associated funds, as well, according to Litan.
In , for example, the Japanese online crypto exchange Mt. Many smaller thefts have taken place over the past five years, mostly through the hacks of online wallets. This is the primary reason we recommend not storing any cryptocurrency balances in online wallets," Litan wrote in a research note earlier this year.
Gartner recommends converting cryptocurrency into fiat money — cold hard cash, as in real dollars, Euros, Yen or some other currency — for safe-keeping, or storing crypto keys in a cold wallet. The latter then means making a paper copy of the keys and storing that paper in a secure place such as a bank safety deposit box. Paper can also be used as a type of wallet through software that creates a QR code that can be scanned to enable blockchain transactions.
Otherwise, Gartner recommends the use an online exchange with a wallet service that enforces two-factor authentication through push technology. Push technology binds the second factor to a registered mobile phone, so that only an owner's phone can approve an access request pushed out by the exchange wallet's authentication service.
Centralized wallet services have been lucrative targets in the past because hackers could make off with millions of dollars' worth of cryptocurrency in just a few minutes.
But cryptocurrency hackers have also successfully stolen the SIM identity of a mobile phone with a phone-based wallet on it, according to Huseby. It's important to recognize that determined criminals can circumvent most phone authentication techniques using a variety of methods, according to Gartner.
These include "SIM swaps," where a thief registers an existing number to his or her phone, so that push notifications or messages are sent to that phone, instead of to the legitimate owner. Hackers do this typically through social engineering of mobile phone customer service representatives, Gartner's report said. There have also been thefts of cryptocurrency via malware planted onto a cryptocurrency owner's device, allowing their secret keys to be stolen. Most people are not familiar with the levels of security and paranoia that is required to truly defend against people determined to steal your keys.
The main problem with a cold wallet, however, is if you haven't backed up the information on it or stored a hard copy of it somewhere secure — and you lose that device — you lose your digital assets for good.
Simply put, you no longer know where your cryptocurrency resides on a blockchain or have the keys to authenticate that you are the owner. Hot storage wallets, in contrast, have the benefit of service provider support. If you lose your access code to the wallet, there are challenge-and-answer questions that will allow you to recover them. Conversely, there are limited methods for recovering private keys in a cold storage wallet that has been lost, and they are generally not easy to use.
For example, Coinbase allows users a restore mechanism that consists of 24 random word recovery phrase users are supposed to record when they create their wallet. Blockchain ledgers work based on a trustless consensus mechanism, meaning you don't need to know the person or people you're transacting with on the ledger.
A distributed ledger will trust any transaction properly signed by a valid secret key. That's why protecting keys is so important. While the vast majority of crypto wallet applications are used to store cryptocurrencies such as bitcoin, Ethereum, Ripple or Litecoin, the software can also store the keys to fungible and non-fungible digital tokens representing goods, financial assets, securities, and services. For example, a token stored in a crypto wallet could represent concert or plane tickets, unique artwork or goods in a supply chain — virtually anything with a digital value attached to it.
All distributed ledgers with decentralized consensus mechanisms rely on the capability security model , which means possession of an encryption key — proven with a digital signature over a transaction — authorizes the action the transaction represents. For Bitcoin, the transactions just transfer bitcoins to another encryption key and therefore to another owner. For things like a supply chain, they sign transactions that track the asset being managed e. In the future, a new, "trustless" global economy could be based on blockchain and crypto wallets that enable everything from individual financial or professional histories, tax information, medical information, or consumer preferences to corporations maintaining employee or partner digital identities and controlling application access.

A crypto wallet is a secure, digital wallet for your cryptocurrency. It also allows you to securely send and receive these and other types of cryptocurrencies. There are different types of crypto wallets available, including mobile apps and wallets that look like USB sticks. Although there is some variation, most function in a similar way by storing private key pairings that allow you to sync your wallet across multiple devices to send and receive cryptocurrency. You should definitely know how to use and set up a crypto wallet before you make your first cryptocurrency purchase. Broadly speaking, crypto wallets come in either software or hardware forms. Though each kind functions a bit differently, they are all designed to allow you to securely access any cryptocurrency you own.
