Installing Geth is relatively straightforward. This can be used to connect directly, or through a language-specific library, such as web3.js. In order for applications to connect to a running Geth instance, a JSON RPC API is exposed. The blockchain state is stored in the LevelDB key-value database. The actual Ethereum-specific module implements the Ethereum Virtual Machine for transaction processing. Whisper is a decentralized messaging protocol that allows communication between endpoints without relying on blockchain transactions. Swarm is a distributed file system, akin to the Interplanetary Filesystem (IPFS), which is aimed at storing large amounts of data cheaply and in a decentralized manner. Apart from the actual Ethereum client implementation, Geth also includes Swarm and Whisper. On top of the P2P mechanism, Ethereum Geth implements three main modules.

Eventually, every node should receive relayed messages as they spread throughout the entire network. The idea is simple but powerful: nodes on the network relay messages to other nodes that they are directly connected to, these nodes can be regarded as being their neighbours. This classic distributed systems algorithm stems from the 1980s, and models network communication based on the way epidemics or rumors spread through the population. The communication mechanisms used at this level is based on the Gossip algorithm. At the lowest level, a peer-to-peer (P2P) protocol is in charge of communication on the network, and is also responsible for discovering peers on the network. The above diagram illustrates the architecture of the Ethereum Geth client at a high level. In this article, we discuss Ethereum Geth, its architecture, and how it can be used to run an Ethereum node or light client.

While there are other clients, notably Parity, Geth can be seen as the defacto reference implementation for running an Ethereum node. However, by far the most mature implementation of Ethereum is “Go Ethereum”, abbreviated to Geth.

The goal of Ethereum has always been to provide a number of different client software implementations, written in different programming languages, that will foster a diverse ecosystem within Ethereum. Participation in the Ethereum blockchain can be done by making use of Ethereum Geth, the command line interface for running a node on the Ethereum network, which has been implemented using the Go programming language. Even for actions such as simply sending a transaction to the network, a node is usually required. In order to participate in a blockchain, there usually is a need to run some form of client software that implements the features required to become a node. 0 Shares Ethereum Geth: Installing and Running a Node
