What Is RPC in Ethereum?

RPC is an acronym for “remote procedure call”. It is a protocol that allows a user to interact with a blockchain network.

RPC is used by Ethereum clients to communicate with each other.

RPC can be used to query information about the blockchain, such as the current block height, the latest block hash, or the balance of a particular account. It can also be used to submit transactions to the network.

RPC calls are made over HTTP, and they use JSON-RPC format.

There are two types of RPC calls: those that require a wallet to be unlocked, and those that don’t. The former type of RPC call can only be made by an Ethereum node that has been configured with a wallet and is unlocked.

The latter type of RPC call can be made by any node, regardless of whether it has a wallet or not.

NOTE: WARNING: RPC (Remote Procedure Calls) in Ethereum can be dangerous and should be used with caution. RPC calls allow a user to interact with a remote node on the Ethereum network, making it possible to execute transactions and read blockchain data. Any malicious actor that has access to an Ethereum node can potentially control or modify the transactions and data on the blockchain. Therefore, it is important to secure your RPC connections and practice safe computing when using RPC in Ethereum.

When an RPC call is made, the node will first check if it has the required information cached. If it doesn’t, it will fetch the required data from other nodes in the network.

Once the data is fetched, it will be returned to the caller in the form of a JSON-RPC response.

The most common use case for RPC is to query information about the blockchain. For example, you can use RPC to get the current block height, or the balance of a particular account.

You can also use RPC to submit transactions to the network. Transactions are signed locally before being broadcasted to the network.

The advantage of using RPC over other methods (such as web3) is that RPC is much faster and simpler. Web3 calls have to go through a lot of layers before they reach the Ethereum network, which makes them slower.

In addition, web3 calls are often asynchronous, which can make them difficult to use.
