Why are there multiple types of clients?
In ethereum’s early engineering, several different clients have been implemented on many different operating systems, which is a huge win for the entire Ethereum ecosystem. It allowed us to verify the clarity of the protocol (specified in the Ethereum Yellow Book), opened the door to new innovations, and kept us all honest. However, this also frustrated many new users, as there was never an “Ethereum install pack” for them to use.
As of September 2016, the two most popular clients are the Go client (Go-Ethereum) and the Rust client (Parity).
| Client | Language | Developers | Latest release |
|---|---|---|---|
| Go Client (Go-Ethereum) | Go | Ethereum Foundation | Go – ethereum – v1.4.18 |
| Rust Client (Parity) | Rust | Ethcore | Parity – v1.4.0 |
| C++ client (cpp-ethereum) | C++ | Ethereum Foundation | CPP – ethereum – v1.3.0 |
| Python client (Pyethapp) | Python | Ethereum Foundation | Pyethapp – v1.5.0 |
| JavaScript library (ethereumjs – lib) | Javascript | Ethereum Foundation | Ethereumjs – lib – v3.0.0 |
| Java Client (Ethereum(J)) | Java | <ether.camp> | EthereumJ – v1.3.1 |
| Ruby Client (Ruby-Ethereum) | Ruby | Jan Xie | Ruby – ethereum – v0.9.6 |
| Haskell tools (ethereumH) | Haskell | BlockApps | no Homestead release yet |
What kind of client should I install on my desktop/laptop?
Most users will choose to install Mist/Ethereum Wallet, which is enough for most needs.
The Ethereum Wallet, which originated in Homestead and was the focus of Metropolis, can be considered an application of MistBrowser.
Mist comes with a binary executable compiled by the Go client (go-ethereum) or C++ client (cp-ethereum) project. If you’re not running the command line version of the ethereum client, Mist starts and calls one of them to synchronize blockchain data (geTH by default). If you want Mist to work with the Parity client, or if you want Mist to run on a private chain, start your Parity client before YOU start Mist, and THEN Mist will connect to the Parity node instead of starting its own client node.
Work is in progress to add Parity or other clients to Mist.
If you want to interact directly with Ethereum using a command line tool and a Javascript console, you can install a client application directly, as shown in the table above.
Mist will not be able to do this if you want to do mining, you need to refer to this section: The Mining section.
What kind of client do I install on my phone/tablet?
Our support for mobile devices is still in the very early stages. The Go team has released a trial development library for iOS and Android that some developers can use to develop Ethereum, but there is no mobile client available at this time.
The biggest hurdle for ethereum mobile clients is that ethereum’s lightweight support is not yet complete. Support is currently only available on the Go client’s private chain, and lightweight clients will be developed for C++ in the coming months.
What kind of client do I install on my board?
Depending on your skill level and usage, there are several options for you:
- Download a ready-made image
- If you’re new to Ethereum and single-board computers (e.g. Raspberry Pi www.raspberrypi.org), this is the best solution for you. Just download an image file for your device, burn it to your device’s SD card, boot up your device, and run Ethereum.
- Download a precompiled application
- If you have the system you need installed and set up on your PC, then this solution is for you. Depending on your system platform, you download the appropriate executables from the download page, and then set dependency libraries and environment variables to run Ethereum in your current environment.
- Compile from source using custom scripts (see this link for more detailsgithub.com/ethembedded)
- Looking for ways to customize your installation? We will provide scripts that can be compiled on the source device. The script includes dependencies needed to automatically install the client. Allows you to install a specific version of the Ethereum client (e.g., development, mainline, etc.) and compile your own branch of the client code.
