This code is stored on a <strong>blockchain<\/strong>, a decentralized and immutable ledger.<\/p>\n<p>The process begins when two or more parties agree to the terms outlined in the smart contract. These terms are then translated into code and deployed to the blockchain. Once deployed, the contract becomes automatically executable based on predefined conditions.<\/p>\n<p><strong>Triggers<\/strong> initiate the execution. These could be anything from a specific date and time to the receipt of funds or the fulfillment of other contractual obligations. When a trigger is met, the <strong>blockchain<\/strong> automatically executes the predetermined actions specified in the contract&#8217;s code. <\/p>\n<p>This automation removes the need for intermediaries, reducing costs and increasing efficiency. Because the code resides on a <strong>decentralized ledger<\/strong>, it&#8217;s transparent and tamper-proof, fostering trust and accountability among all parties involved.<\/p>\n<p><strong>Crucially<\/strong>, smart contracts operate based on pre-defined logic; they can&#8217;t be altered once deployed (unless explicitly programmed to allow for modifications). This immutability ensures the integrity and reliability of the contract&#8217;s execution.<\/p>\n<p>In essence, smart contracts utilize <strong>blockchain technology<\/strong> to automate the execution of agreements, eliminating the need for intermediaries and increasing transparency and trust.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Popular_Platforms_for_Smart_Contracts\"><\/span>Popular Platforms for Smart Contracts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure class=\"wp-caption aligncenter\"><img decoding=\"async\" src=\"https:\/\/kazu.co.id\/crypto\/wp-content\/uploads\/2024\/12\/Popular-Platforms-fo.webp\" class=\"size-full\"><figcaption class=\"wp-caption-text\">Popular Platforms for Smart Contracts (Image source: www.blockchain-council.org)<\/figcaption><\/figure>\n<p>Smart contracts, self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code, rely on specific platforms for their execution.
