Trustless in a sense that personal nodes autonomously verify all transactions and blocks against consensus rules. This way a user does not have to depend on any other nodes in the network. Instead, everything can be verified with the client directly. What is an Ethereum client?

The Ethereum client represents the software that is needed by an Ethereum node to read and verify the blocks of the Ethereum blockchain. The behavior of an Ethereum node is influenced by the client software it runs. An Ethereum client enables developers to interact with the network and its nodes through several programming languages. Some of the different programming languages used by various clients supported by the Ethereum Foundation include Rust, Go, Java, and C.

The most important function of an Ethereum client is to provide an interface to verify transactions, mine blocks, and more. Ethereum clients can be classified into three types. They include: Full Client Full clients store the entire Ethereum network. Storing the full Ethereum blockchain can take several days and needs a huge size of disk storage.

Full clients support linked nodes to perform most functions on the network including verifying transactions, mining , running smart contracts , and more. Light Client Light clients are suitable for developers looking for faster speeds and fewer storage requirements.

Light clients can be considered as a lesser version of a full client. Unlike full clients, light clients do not store the entire Ethereum blockchain network and thus improve transaction speeds and free up data storage. Light clients handle smart contract interactions and broadcast transactions. Light clients are also used to interface private keys and Ethereum addresses within a crypto wallet.

Remote Client While almost similar to a light client, it differs by not storing a copy of the Ethereum blockchain. A remote client does not validate transactions. Remote clients depend on full and light clients to enable access to the Ethereum network. Act as wallets for sending and receiving digital tokens. An example of how an Ethereum client works is MetaMask, a browser and app-based crypto wallet. MetaMask is a remote client that interfaces with the blockchain via a light client.

For security, MetaMask uses its light client to communicate with the remote client. The remote client is responsible for wallet storage capability, broadcasting transactions, and more. How to run an Ethereum client There are several kinds of official and unofficial client software available to use such as Geth , WebThree , Parity , Hyperledger Besu , and Nethermind.

Instead of trusting a single client, software nodes are incentivized to run different client implementations with the goal that no client software should have a super majority. Instead, the ecosystem should strive for client diversity, which entails having a fair distribution of client software on network nodes. Ideally, no Ethereum client should power the majority of nodes in the Ethereum network. Here is an overview of the different client solutions. As we observed earlier, nodes and clients are often mentioned together but they are not the exact same thing.

Ultimately, nodes are computers that are equipped with a software application, known as a client. Retrieving full data can also be very time consuming, sometimes taking multiple days to sync your data when the node is first deployed. Then, the node must be maintained, upgraded and kept online in order to not have to repeat the full synchronization process. Light nodes are similar to the full node but handle less information. The light node stores header chain information basic information stored in a block such as a timestamp and the hash of the previous block, but will only receive additional information upon request.

They are able to verify the validity of data but do not fully participate in block validation. Light nodes are almost always implemented within remote clients. Because these nodes do not take on more intensive data storage and writing processes, they have proven to be useful for low-capacity devices like smartphones. Archive nodes are nodes that store all of the information that a full node does and builds an archive of historical blockchain states. Archive nodes will retain historical data even after a client has finished synchronization.

While archive nodes may not be useful for the average user, they have proven effective in the application of block explorers, wallet vendors and chain analytics. What is an Ethereum client?

Related tutorials Introduction Running your own Ethereum node can be challenging, especially when getting started or while scaling fast. There are a number of services that run optimized node infrastructures for you, so you can focus on developing your application or product instead.

We'll explain how node services work, the pros and cons for using them and list providers if you are interested in getting started. Prerequisites If you don't already have an understanding of what nodes and clients are, check out Nodes and clients. Stakers Solo stakers must run their own infrastructure rather than relying on third-party providers.

This means running an execution client coupled with a consensus client. Before The Merge , it was possible to run a consensus client only and use a centralized provider for execution data; this is no longer possible - a solo staker must run both clients. However, there are services available to ease this process. The services described on this page are for non-staking nodes. How do node services work?

Node service providers run distributed node clients behind the scenes for you, so you don't have to. These services typically provide an API key that you can use to write to and read from the blockchain. They often include access to Ethereum testnets in addition to Mainnet. Some services offer you your own dedicated node that they manage for you, while others use load balancers to distribute activity across nodes. Access to the RPC interface can be extended through the development of edge layer APIs or web server applications, like Nginx, and connecting them to your client's local address and port.

Leveraging a middle layer can also allow developers the ability to setup a certificate for secure https connections to the RPC interface. Another privacy-preserving way to set up a publicly reachable endpoint is to host the node on your own Tor onion service.

This will let you reach the RPC outside your local network without a static public IP address or opened ports. However, using this configuration may only allow the RPC endpoint to be accessible via the Tor network which is not supported by all the applications and might result in connection issues. To do this, you have to create your own onion service.

Checkout the documentation on onion service setup to host your own. Lastly, and one of the most popular ways to provide access to internal networks is through a VPN connection. Depending on your use case and the quantity of users needing access to your node, a secure VPN connection might be an option.

Operating the node You should regularly monitor your node to make sure it's running properly. You may need to do occasional maintenance. Keeping a node online Your node doesn't have to be online all the time, but you should keep it online as much as possible to keep it in sync with the network. You can shut it down to restart it, but keep in mind that: Shutting down can take a few minutes if the recent state is still being written on disk.

Forced shut downs can damage the database requiring you to resync the entire node. Your client will go out of sync with the network and will need to resync when you restart it. While the node can begin syncing from were it was last shutdown, the process can take time depending on how long it has been offline.

This doesn't apply on consensus layer validator nodes. Taking your node offline will affect all services dependent on it. If you are running a node for staking purposes you should try to minimize downtime as much as possible. Creating client services Consider creating a service to run your clients automatically on startup.

For example, on Linux servers, good practice would be to create a service, e. Updating clients You need to keep your client software up-to-date with the latest security patches, features, and EIPs. Especially before hard forks , make sure you are running the correct client versions.

Before important network updates, EF publishes a post on its blog. You can subscribe to these announcements to get a notification to your mail when your node needs an update. Updating clients is very simple. Each client has specific instructions in their documentation, but the process is generally just to download the latest version and restart the client with the new executable. The client should pick up where it left off, but with the updates applied.

Each client implementation has a human-readable version string used in the peer-to-peer protocol but is also accessible from the command line. This version string lets users check they are running the correct version and allows block explorers and other analytical tools interested in quantifying the distribution of specific clients over the network. Please refer to the individual client documentation for more information about version strings.
