The geth client communicates with the blockchain by way of a full node. A full node is a program that fully validates transactions and blocks. Every full node in the Ethereum network stores a complete copy of the blockchain, in addition to maintaining a real-time transaction relay network. The geth client interacts with full nodes in order to relay transactions and blocks between each other.

Q: What is the default way of connecting to a Geth client?

A: The Geth client can be connected to via various means, depending on how it is configured. By default, the Geth client will attempt to connect to other Geth clients on the same network via the IPC RPC interface. Alternatively, the Geth client can be configured to connect to other Geth clients via the JSON-RPC interface over HTTP or WebSockets.

Q: How do you interact with the Geth node?

A: There are a variety of ways to interact with a Geth node. The most common way is to use the command line interface (CLI), which is included in the Geth distribution.

Alternatively, you can use one of the many third-party tools that have been developed to work with Geth. These include graphical user interfaces (GUIs) and programming interfaces (APIs).

Q: What is Geth in blockchain?

A: Geth is a program that implements the Ethereum protocol. It is written in the Go programming language and is licensed under the GNU LGPLv3. Geth is used to interact with the Ethereum network, including deploying and interacting with smart contracts.

Q: How does Ethereum light client work?

A: Ethereum light client is a client that can synchronize with the Ethereum network without having to download the entire blockchain.

The light client uses a simplified version of the blockchain called a trie, which only stores the part of the blockchain that is relevant to the user.

The light client also stores a small amount of data called a bloom filter, which allows it to quickly determine which parts of the blockchain are relevant to the user.
