<h2>Indexing</h2>
<p>Indexing in the context of cryptocurrency refers to the process of tracking and recording transactions on a blockchain network.</p>

<h2>How It Works</h2>
<p>Indexing involves creating a database of transaction data, known as an index, which is stored off-chain. This index is updated in real-time as new transactions are added to the blockchain. Indexing serves two primary purposes:</p>
<ul>
  <li>Improving transaction lookup speed: Instead of scanning the entire blockchain, users can query the index to quickly find specific transactions.</li>
  <li>Enabling off-chain computation: Indexing allows for complex calculations and analytics to be performed off-chain, reducing the computational load on the blockchain network.</li>
</ul>
<p>There are two main types of indexing:</p>
<ul>
  <li><strong>Full indexing</strong>: This involves creating an index of every transaction on the blockchain. It provides the most comprehensive data but requires significant resources.</li>
  <li><strong>Partial indexing</strong>: This approach only indexes specific types of transactions or addresses, making it more resource-efficient but less comprehensive.</li>
</ul>

<h2>Why It Matters</h2>
<p>Indexing is crucial for the scalability and usability of blockchain networks. It enables faster and more efficient transaction lookups, which is particularly important for applications that rely on frequent or complex data queries. For example, decentralized finance (DeFi) platforms use indexing to track loan positions, calculate interest, and manage other financial operations. Without indexing, these platforms would be significantly slower and less functional.</p>
