When you hear Smart contracts, self‑executing agreements that automatically enforce terms once conditions are met on a blockchain. Also known as self‑executing contracts, they eliminate middlemen and cut costs.
Blockchain, a distributed ledger that records transactions in immutable blocks provides the trust layer that makes these contracts reliable. Without a tamper‑proof ledger, a contract can’t guarantee that the code won’t be altered. Ethereum, the leading smart‑contract platform that introduced a Turing‑complete virtual machine took this concept mainstream, allowing anyone to deploy code that runs exactly as written.
To write that code, developers use Solidity, a high‑level programming language designed for creating smart contracts on Ethereum. Solidity translates business logic into bytecode the Ethereum Virtual Machine can execute. This creates a direct link: smart contracts require Solidity (or similar languages) to be expressed, and Solidity needs Ethereum’s infrastructure to run.
Decentralized applications, or dApps, software applications that run on a blockchain instead of a centralized server, rely on smart contracts for core functionality—whether it’s token swaps, lending, or gaming mechanics. The relationship is simple: dApps depend on smart contracts to store state, enforce rules, and handle value transfers without a central authority. This makes them more resilient and transparent, qualities that traditional apps struggle to provide.
Across the articles below you’ll see how each piece fits into this ecosystem. Some posts dive into the technical side—like how Solidity code is audited—while others explore real‑world use cases, from DeFi platforms to blockchain voting systems. Together they give you a full picture of how smart contracts shape the future of finance, governance, and digital interaction.
