A Public Blockchain API is an application programming interface that allows developers to interact with a public blockchain network. It provides a set of protocols and tools to facilitate communication between applications and the blockchain.These APIs enable functionalities such as querying blockchain data, submitting transactions, and accessing various blockchain services. Developers can easily integrate blockchain capabilities into their applications without needing to understand the underlying architecture in detail.Public Blockchain APIs are typically hosted by third-party providers or the blockchain network itself. They often offer features like wallet management, transaction broadcasting, and smart contract interactions.By using a Public Blockchain API, developers can build decentralized applications (dApps) that leverage the transparency and security of blockchain technology. This opens up possibilities for creating innovative solutions, ranging from finance to supply chain management. Overall, Public Blockchain APIs are essential tools for developers looking to harness the benefits of blockchain in their projects.
