Nodes are the “knots” of the blockchain systems interconnected to create the distributed network and secure it. One node can be launched on one separate device or be a part of the software-hardware complex where the node is allocated alongside others. There are a lot of types of nodes: Web3 industry has light nodes, archival nodes, mining nodes, masternodes, and others. Each has its own specialization in transferring information through the network.
The best way to get the API for your needs is to read the documentation of the dedicated blockchain. There are lots of APIs available for different needs: Websockets, Rest APIs, Payment Processing APIs, Simple Query APIs, Blockchain Data API, and so on. RPC Fast, as nodes as a service, provides you with all the functionality of the selected network with the help of a blockchain API. Thus you can simply connect it with your project.
Depending on the type of node, each node has its own functions, states, and work procedures. But all-in-all, even blockchain nodes for sale exist to validate transactions and store the information about transactions. Nodes are unique tools of distributed systems as each of them stores the whole information about their network. With each new transaction in the blockchain, all nodes are updating at the same time to keep their information fresh.
This type of architecture is a distributed network that keeps the data about all events that happened inside each node that participates in it. With such distributed architecture, the environment is pretty secure yet transparent and trustable. This technology is often applied for financial tools, but it’s gone far beyond in other industries now.
Any blockchain Application Programming Interface (API) is a developer’s tool to get access to the functionality of blockchain and implement it into any other project. Depending on the API itself, the access might be direct or limited with some kind of service interface that’s built upon the API. RPC Fast is the fastest API-based node-as-a-service blockchain industry deserves.
