description: Introduction to mobile development with Geth

Embedding clients into mobile devices is an important part of Ethereum's decentralization vision. This is because being able to verify data, follow the chain and submit transactions without relying on centralized intermediaries is critical for censorship resistant access to the network. Doing so on a mobile device is the most convenient route for many users. This relies on Geth running a [light client](/docs/interface/les) on the mobile
Embedding clients into mobile devices is an important part of Ethereum's decentralization vision. This is because being able to verify data, follow the chain and submit transactions without relying on centralized intermediaries is critical for censorship resistant access to the network. Doing so on a mobile device is the most convenient route for many users. This relies on Geth running a [light client](/docs/fundamentals/les) on the mobile
device and exposing an API that developers can use to build mobile apps on top of Geth. This page outlines how to download Geth for mobile and how to get started with managing Ethereum accounts in mobile applications. Ethereum mobile development is relatively nascent, but there is an active developer community. For further information on Geth mobile development visit the #mobile channel in the [Geth discord](https://discord.gg/wQdpS5aA).

The tracing API accepts an optional `tracer` parameter that defines how the data returned to the API call should be processed. If this parameter is ommitted the default tracer is used. The default is the struct (or 'opcode') logger. These raw opcode traces are sometimes useful, but the returned data is very low level and can be too extensive and awkward to read for many use-cases. A full opcode trace can easily go into the hundreds of megabytes, making them very resource intensive to get out of the node and process externally. For these reasons, there are a set of non-default built-in tracers that can be named in the API call to return different data from the method. Under the hood, these tracers are Go or Javascript
functions that do some specific preprocessing on the trace data before it is returned.
More information about Geth's built-in tracers is available on the [built-in tracers](/docs/developers/evm-tracing/builtin-tracers) page.

description: Instructions for managing GitHub issues

## Draft proposal {#draft-proposal}
- Keep the number of open issues under 820
- Keep the ratio of open issues per all issues under 13%
- Have 50 issues labelled [help wanted](https://github.com/ethereum/go-ethereum/labels/help%20wanted) and 50 [good first issue](https://github.com/ethereum/go-ethereum/labels/good%20first%20issue).
- Use structured labels of the form `<category>:<label>` or if need be `<category>:<main>/<sub>`, for example `area: plugins/foobuzzer`.
- Use the following labels. Areas and statuses depend on the application and workflow.
* area
- `area: android`
- `area: clef`
- `area: network`
- `area: swarm`
- `area: whisper`
* type
- `type: bug`
- `type: feature`
- `type: documentation`
- `type: discussion`
* status
- `status: PR review`
- `status: community working on it`
* need
- `need: more info`
- `need: steps to reproduce`
- `need: investigation`
- `need: decision`
Use these milestones
- [Future](https://github.com/ethereum/go-ethereum/milestone/80) - Maybe implement one day
- [Coming soon](https://github.com/ethereum/go-ethereum/milestone/81) - Not assigned to a specific release, but to be delivered in one of the upcoming releases
- \<next version\> - Next release with a version number
- \<next-next version\> - The version after the next release with a version number
- \<next major release\> - Optional.
It's ok to not set a due date for a milestone, but once you release it, close it. If you have a few issues dangling, consider moving them to the next milestone, and close this one.
Optionally, use a project board to collect issues of a larger effort that has an end state and overarches multiple releases.
## Workflow {#workflow}
The Geth core team hold a weekly or bi-weekly triage meeting. Issues are preselected by [labelling them "status:triage" and sorted the oldest ones first](https://github.com/ethereum/go-ethereum/issues?q=is%3Aopen+is%3Aissue+label%3Astatus%3Atriage+sort%3Acreated-asc). This is when the team goes through the new issues and do one of the following
1. Close it.
2. Assign it to "Coming soon" milestone which doesn't have an end date.
3. Move it to the "Future" milestone.
4. Change its status to "Need:\<what-is-needed\>".
Optional further activities:
- Label the issue with the appropriate area/component.
- Add a section to the FAQ or add a wiki page. Link to it from the issue.

This page explains how to set up Geth and execute some basic tasks using the command line tools. In order to use Geth, the software must first be installed. There are several ways Geth can be installed depending on the operating system and the user's choice of installation method, for example using a package manager, container or building from source. Instructions for installing Geth can be found on the ["Install and Build"](/docs/getting_started/Installing-Geth) pages.

Instructions for installing Geth can be found on the ["Install and Build"](/docs/getting-started/installing-geth) pages.
Geth also needs to be connected to a [consensus client](docs/getting-started/consensus-clients) in order to function as an Ethereum node. The tutorial on this page assumes Geth and a consensus client have been installed successfully and that a firewall has been configured to block external traffic to the JSON-RPC port `8545` see [Security](/docs/fundamentals/security).

<Note>If Geth was installed from source on Linux, `make` saves the binaries for Geth and the associated tools in `/build/bin`. To run these programs it is convenient to move them to the top level project directory (e.g. running `mv ./build/bin/* ./`) from `/go-ethereum`. Then `./` must be prepended to the commands in the code snippets in order to execute a particular program, e.g. `./geth` instead of simply `geth`. If the executables are not moved then either navigate to the `bin` directory to run them (e.g. `cd ./build/bin` and `./geth`) or provide their path (e.g. `./build/bin/geth`). These instructions can be ignored for other installations.</Note>
description: How to interact with Geth using Javascript

Geth responds to instructions encoded as JSON objects as defined in the [JSON-RPC-API](/docs/interacting-with-geth/rpc/server). A Geth user can send these instructions directly, for example over HTTP using tools like [Curl](https://github.com/curl/curl). The code snippet below shows a request for an account balance sent to a local Geth node with the HTTP port `8545` exposed.

This is a low level and rather error-prone way to interact with Geth. Most developers prefer to use convenience libraries that abstract away some of the more tedious and awkward tasks such as converting values from hexadecimal strings into numbers, or converting between denominations of ether (Wei, Gwei, etc). One such library is [Web3.js](https://web3js.readthedocs.io/en/v1.7.3/).
The purpose of Geth's Javascript console is to provide a built-in environment to use a subset of the Web3.js libraries to interact with a Geth node.
<Note>The web3.js version that comes bundled with Geth is not up to date with the official Web3.js documentation. There are several Web3.js libraries that are not available in the Geth Javascript Console.

In addition to the [JSON-RPC APIs](/docs/interacting_with_geth/RPC/server), Geth supports the GraphQL API as specified by [EIP-1767](https://eips.ethereum.org/EIPS/eip-1767). GraphQL lets you specify which fields of an objects you need as part of the query, eliminating the extra load on the client for filling in fields which are not needed. It also allows for combining several traditional JSON-RPC requests into one query which translates into less overhead and more performance.
