RPC

What is RPC?

In the realm of Cryptocurrency and Blockchain, RPC, or Remote Procedure Call, is a vital term to understand. It refers to a protocol used by a program or system to request a service from another program located in a different network location. The term 'remote' signifies that the procedure call is happening between two different systems or two different programs within the same system, that are networked together.

How Does RPC Work?

The way RPC works is similar to making a phone call to a friend to ask for a favor. In the context of a blockchain network, one node makes an 'RPC' call to another node, requesting it to perform a specific function. This function could be anything from verifying transactions to adding a new block to the blockchain. The calling node, in this case, plays the role of the client, while the node being called upon becomes the server. Upon receiving the RPC, the server executes the procedure and sends the results back to the client.

Role of RPC in Cryptocurrency Networks

In the context of cryptocurrency networks, RPC is used to carry out a vast range of crucial tasks. For instance, an RPC could command a node to validate a new block of transactions, or it could ask a node to provide information about previous transactions. By enabling such interactions, RPCs help to maintain the integrity and functionality of the entire blockchain network.

Conclusion: Importance of RPC

Understanding the concept of RPC is fundamental for anyone keen on delving deeper into cryptocurrency and blockchain technology. It forms the backbone of inter-node communication within these innovative systems, without which the network would cease to function effectively. Whether you're a novice in the crypto world or a seasoned blockchain developer, understanding RPC is crucial for your journey.
