Blockchain platforms are frameworks that allow developers to build, deploy, and manage decentralized applications (dApps) and smart contracts. These platforms provide essential tools and infrastructure for creating blockchain-based solutions. Prominent blockchain platforms include Ethereum, which supports decentralized finance and dApps; Hyperledger for enterprise use; and Polkadot for interoperability across blockchains. Blockchain platforms offer diverse features such as scalability, security, and governance, catering to various industries, including finance, healthcare, supply chain, and more, driving the adoption of blockchain technology globally.
