Blockchain platforms are frameworks that enable the creation, deployment, and management of decentralized applications (dApps) and smart contracts. These platforms, such as Ethereum, Binance Smart Chain, and Solana, provide developers with the tools and infrastructure needed to build blockchain-based solutions. They offer features like security, scalability, and interoperability, allowing businesses to integrate blockchain technology into their operations. Blockchain platforms support various industries, from finance to supply chain management, and help businesses create secure, transparent, and efficient solutions.
