Bitcoin (BTC)</strong></a>, use inputs and outputs for their transaction mechanics.</p>\n<p>Cryptocurrency transactions are completed using inputs and outputs. Inputs are addresses that the cryptocurrency is sent from at the start of the transaction, and the output is the address of the final destination.</p>\n<p>During cryptocurrency transactions, the wallet does not send out only the specific amount. Instead, assets linked to the particular wallet address are converted into the input. Any unspent assets are returned back to the initial wallet as unspent transaction output. UTXO can be used in other transactions in the future.</p>\n<p>If person A has 50 BTC and decides to send 10 BTC to person B, they must first unlock the 50 UTXOs in the wallet. All 50 coins are used as the transaction input. The transaction forwards 10 BTC to person B. The remaining 40 BTS return to the wallet belonging to person A as new UTXOs. Person B&rsquo;s wallet now contains two separate UTXCOs &ndash; the previous balance and the additional coins sent by person A.</p>\n<p><a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-validator/">Validators can verify that a transaction is valid if the total number of inputs is equal to or higher than the number of outputs<strong>.</strong> This mechanism ensures that users do not <a href=https://www.bitdegree.org/"/crypto/learn/crypto-terms/what-is-double-spending/">double-spend their assets.</p>","level":"easy","meta_title":"What is Unspent Transaction Output (UTXO)?

In essence, <strong>UI determines how your website or application appears to the visitor both in its functionality and appearance.</strong> It includes a wide range of elements such as the layout of your website, color scheme, call-to-action buttons, various functions, and much more.</p>\n<p>In case your user interface is not up to par, the users can leave your website without even checking out what&rsquo;s on it.</p>\n<h2>Why is User Interface Important?</h2>\n<p>UI is just like the first meeting between a user and a website. In order to leave a good first impression, the interactions should be smooth, the visuals should be appealing, and the website should be easy to navigate. In essence, make sure your UI is as effortless as possible.</p>\n<p><strong>A great user interface has a</strong> <strong>chance of vastly improving your conversion rate</strong> which defines the percentage of visitors that completed your desired action within the website or application.</p>\n<p>On the other hand, the issue with a bad UI is that users probably won&rsquo;t inform you that it&rsquo;s difficult to navigate through your website or application. Often times it&rsquo;s because they don&rsquo;t understand it themselves. They just know that it didn&rsquo;t do what they wanted, so, they left.</p>\n<p>If visitors leave because of bad UI, chances are they won&rsquo;t come back again.

At the end of the day, <strong>UI needs to be user-friendly, intuitive, and appealing to the eye</strong> while keeping in mind the image of the brand.</p>\n<p>One of the main rules of a great user interface is that the user is able to understand what your application is about and how to use it within 5 seconds. In other words, the UI should feel somewhat invisible to the user where the interaction is so smooth that they don't have to waste a single second.</p>\n<p>Here are some guidelines to create a great user interface:</p>\n<ul>\n<li><strong>Simplicity is key</strong>. Don&rsquo;t overflow the interface with unnecessary content or lines of text. Think of your favorite website, chances are it&rsquo;s simple and straightforward, and that is exactly what makes it fun to use.</li>\n<li><strong>Establish what your visitors will be searching for</strong>, and use that information to drive conversions. Remember that everything your visitor is looking for should be a click or two away.</li>\n<li>Make sure to <strong>utilize the navigation bar on the top of the website</strong> to provide straightforward instructions to your website visitors. Don&rsquo;t forget that the right visual design (color scheme, font, size, etc.) can help to draw attention.</li>\n<li>Check if your UI is <strong>mobile-friendly</strong>. Especially in cases where the target audience of the website uses smartphones and tablets for browsing.</li>\n</ul>","level":"hard","meta_title":"What is User Interface (UI)?

What is Unspent Transaction Output (UTXO)?

Unspent Transaction Output (UTXO) MEANING:
Unspent Transaction Output (UTXO) - the unspent cryptocurrency that returns to the wallet after a transaction.
Easy
1 minute

Let's find out Unspent Transaction Output (UTXO) meaning, definition in crypto, what is Unspent Transaction Output (UTXO), and all other detailed facts.

Unspent transaction output (UTXO) is the leftover output from a cryptocurrency transaction that was not used as input. Many cryptocurrencies, including Bitcoin (BTC), use inputs and outputs for their transaction mechanics.

Cryptocurrency transactions are completed using inputs and outputs. Inputs are addresses that the cryptocurrency is sent from at the start of the transaction, and the output is the address of the final destination.

During cryptocurrency transactions, the wallet does not send out only the specific amount. Instead, assets linked to the particular wallet address are converted into the input. Any unspent assets are returned back to the initial wallet as unspent transaction output. UTXO can be used in other transactions in the future.

If person A has 50 BTC and decides to send 10 BTC to person B, they must first unlock the 50 UTXOs in the wallet. All 50 coins are used as the transaction input. The transaction forwards 10 BTC to person B. The remaining 40 BTS return to the wallet belonging to person A as new UTXOs. Person B’s wallet now contains two separate UTXCOs – the previous balance and the additional coins sent by person A.

Validators can verify that a transaction is valid if the total number of inputs is equal to or higher than the number of outputs. This mechanism ensures that users do not double-spend their assets.
