It is not necessary to be forcibly miners and \/ or nodes in order to use the <strong>blockchain<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The word <b><strong>wallet<\/strong> <\/b>stands for <b>&#8220;digital <strong>wallet<\/strong>&#8220;<\/b>. Its purpose is comparable to a <b>home banking<\/b>, a <b>smartphone <\/b>credit top up <b>dashboard <\/b>, or to our <b>PayPal <\/b>account that we use to buy for example on the internet: it has the purpose of transferring money, but, in this case, with the difference which allows access to the potential of the <strong>blockchain<\/strong>.<\/p>\n\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Types of wallets<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It is basically a software that allows you to buy or sell cryptocurrency. The <b>software version <\/b>is actually the most used: it can be installed on desktop PCs, laptops, tablets, smartphones or even to be consulted online from anywhere without having that particular device (computer or smartphone) at hand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, they also exist in <b>a hardware version:<\/b> for example, as <b>USB pen <\/b>, easily transportable, it can then be quickly connected to any device (PC, laptop, smartphone tablet) to complete purchases or sales in cryptocurrency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><b>Paper wallets <\/b>are very popular from the very beginning: these types of wallets require a <b>Qr-Code<\/b>, which can then be scanned by any device equipped with special software to enable a money transfer ( for example).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The use of the <b><strong>Qr-Code<\/strong> <\/b>is very developed, especially in asian countries: this easy to use tool allows it to be <b>&#8220;read&#8221; by the camera of mobile phones <\/b>or <b>tablets <\/b>(previously enabled for this type of reading). Reading this <b><strong>Qr-Code<\/strong> <\/b>allows the user to quickly <b>send <\/b>the desired sum (money) to the merchant who exposed this <strong>Qr-Code<\/strong>.<\/p>\n\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What is the wallet and its advantages for?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/affidaty.io\/blog\/en\/2019\/07\/possible-blockchain-applications\/#content\"><b>advantages<\/b><\/a> of a system of this magnitude are considerable, starting with the payment and filing speed of the receipt and\/or invoice, both on the user side and on the merchant side, allowing (for example) the operator to be able to generate a history of invoices or receipts &#8220;certified&#8221; by the <strong>blockchain<\/strong> itself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As we previously learned <a href=\"https:\/\/affidaty.io\/blog\/en\/2019\/07\/inside-blockchain-the-transaction-how-and-by-what-it-is-composed\/#content\">in the transaction article<\/a>, the <b><strong>blockchain<\/strong> <\/b>system involves the use of <b>public and private keys<\/b>. They are of great importance here too, in personal wallets. Inside the wallets they work for:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u25cf enable <b>user recognition<\/b>: if a user loses the private key he could not access his <strong>wallet<\/strong>;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u25cf start the <b>transactions<\/b>: when the user \u201cA\u201d creates a transaction, the software, starting from the private key, generates a &#8220;digital signature&#8221;, as we learned <a href=\"https:\/\/affidaty.io\/blog\/en\/2019\/07\/inside-blockchain-the-transaction-how-and-by-what-it-is-composed\/#content\">in the transaction article<\/a>;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u25cf <b>&#8220;geolocate&#8221; <\/b>the correct <strong>wallet<\/strong> with which to communicate to buy and\/or sell and\/or simply transfer money: each wallet has an address, comparable to a banking IBAN. It is an alphanumeric code which we must then use as a personal &#8220;address&#8221; to communicate to those who must send us some money.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Just above we have taken PayPal as an example: here we have our first and last name as identification, but above all our e-mail. In <strong>blockchain<\/strong>, everything is replaced by <b>alphanumeric codes <\/b>generated automatically and randomly by the <strong>wallet<\/strong> software.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To date there are no particular limits to the number of wallets a user can create, unless a rule is entered by the used <strong>blockchain<\/strong> system. Once the <strong>wallet<\/strong> has been created, we will have a platform (dashboard) with which we will be able to perform operations such as:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u25cf keep cryptocurrency; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u25cf send or receive cryptocurrency; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u25cf check the history of transactions that have been stored here. &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By connecting your <strong>wallet<\/strong> to the various e-commerce (e-bay and similar) present on the network that enable the payment and receipt of cryptocurrency, we can even use it to buy and\/or sell on the internet.<\/p>\n\n\n\n<div style=\"height:52px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Wallet: a bit of numbers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are really many wallets available on the market, only for Bitcoin we can see some examples <a href=\"https:\/\/bitcoin.org\/en\/choose-your-wallet?step=5&amp;platform=ios\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (apre in una nuova scheda)\">here<\/a> .<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At numerical levels, only for <a rel=\"noreferrer noopener\" aria-label=\" (apre in una nuova scheda)\" href=\"https:\/\/www.blockchain.com\/it\/charts\/my-wallet-n-users\" target=\"_blank\">Bitcoin<\/a> reliable sources speak of a number that exceeds <a href=\"https:\/\/www.blockchain.com\/it\/charts\/my-wallet-n-users\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (apre in una nuova scheda)\">40 million open wallets<\/a>.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/www.blockchain.com\/it\/charts\/my-wallet-n-users\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Bitcoin-statista-wallets-1.jpg\" alt=\"Wallets available on the market\" class=\"wp-image-884 lazyload\"><noscript><img decoding=\"async\" width=\"600\" height=\"347\" src=\"https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Bitcoin-statista-wallets-1.jpg\" alt=\"Wallets available on the market\" class=\"wp-image-884\" srcset=\"https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Bitcoin-statista-wallets-1.jpg 600w, https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Bitcoin-statista-wallets-1-300x174.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/noscript><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">While for <a rel=\"noreferrer noopener\" aria-label=\" (apre in una nuova scheda)\" href=\"https:\/\/etherscan.io\/chart\/address\" target=\"_blank\">Ethereum<\/a> the figure <a href=\"https:\/\/etherscan.io\/chart\/address\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (apre in una nuova scheda)\">surpasses 70 million<\/a>.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/etherscan.io\/chart\/address\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Ethereum-data-wallets-1.jpg\" alt=\"Ethereum wallet\" class=\"wp-image-885 lazyload\"><noscript><img decoding=\"async\" width=\"600\" height=\"317\" src=\"https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Ethereum-data-wallets-1.jpg\" alt=\"Ethereum wallet\" class=\"wp-image-885\" srcset=\"https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Ethereum-data-wallets-1.jpg 600w, https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Ethereum-data-wallets-1-300x158.jpg 300w, https:\/\/affidaty.io\/blog\/wp-content\/uploads\/2019\/09\/Ethereum-data-wallets-1-768x406.jpg 768w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/noscript><\/a><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Being a digital tool, all the rules that we follow with any other digital tool apply to the <strong>wallet<\/strong>, that is to pay attention to viruses and \/ or trojans that could be present on the devices we use to connect to it, whether we do it through software or through usb or <strong>Qr-Code<\/strong> (or NFC).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>wallet<\/strong> itself, leaning on the entire <strong>blockchain<\/strong> structure, is an instrument of high security, but being digital, it must be used with common devices such as a computer or a smartphone.
