📚 Blockchains are decentralized networks made up of many nodes.
However, most users and applications do not connect directly to every node in the network.
Instead, they communicate with the blockchain through a system called RPC.
RPC stands for Remote Procedure Call.
It is a method that allows applications to send requests to a blockchain node and receive data in return.
Through RPC, wallets, websites, and decentralized applications can interact with the blockchain.
They can request information such as account balances, transaction history, or send new transactions to the network.
Here are the key ideas behind RPC.
1️⃣ Connects applications to the blockchain
RPC allows software like wallets or dApps to communicate with blockchain nodes.
2️⃣ Sends requests and receives data
Applications can ask for information such as block data, balances, or transaction status.
3️⃣ Allows users to submit transactions
When you send crypto using a wallet, the request is usually transmitted through an RPC connection.
4️⃣ Makes blockchain interaction possible
Without RPC services, most applications would not be able to interact easily with blockchain networks.
A simple example can help explain this idea.
Imagine a customer ordering food from a restaurant.
Instead of going directly into the kitchen, the customer gives the order to a waiter.
The waiter delivers the request to the kitchen and then brings the food back to the customer.
RPC works in a similar way.
Applications send requests to a blockchain node through RPC, and the node returns the requested information.
This system allows millions of users and applications to interact with blockchain networks smoothly.
