+        <h2>Unspent Transactions Output (UTXO)</h2>
+        <p>The Unspent Transaction Output (UTXO) model is fundamental to Bitcoin's transaction process. It refers to the Bitcoin that is available for spending after previous transactions have been completed. Each UTXO represents a specific amount of Bitcoin that can be used in future transactions. This model not only helps maintain the integrity of the blockchain by ensuring that coins cannot be double-spent, but it also allows for a clear and precise accounting of Bitcoin’s availability. Understanding the UTXO model is essential for anyone looking to engage with Bitcoin transactions effectively.</p>

         <h2>Issuance</h2>
         <p>Bitcoin issuance refers to the creation of new coins, which occurs through a process called mining. New Bitcoins are generated as miners solve complex mathematical problems to validate transactions on the network. This structured issuance is capped at 21 million coins, making Bitcoin a deflationary asset. Understanding Bitcoin's issuance helps you appreciate its scarcity and how it differs from traditional currencies, which can be printed without limit. This unique system ensures that Bitcoin maintains value over time and provides a predictable monetary supply.</p>
