directory.
| Command | Description |
|:----------:|-------------|
| **`geth`** | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default), archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. |
| `abigen` | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. |
| `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks. |
| `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). |
| `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs. Please see the [test suite's readme](https://github.com/ethereum/rpc-tests/blob/master/README.md) for details. |
| `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ethereum/wiki/wiki/RLP)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`). |
| `swarm` | Swarm daemon and tools. This is the entrypoint for the Swarm network. `swarm --help` for command line options and subcommands. See [Swarm README](https://github.com/ethereum/go-ethereum/tree/master/swarm) for more information. |
| `puppeth` | a CLI wizard that aids in creating a new Ethereum network. |

## Running geth
## Running `geth`
Going through all the possible command line flags is out of scope here (please consult our
[CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options)), but we've
enumerated a few common parameter combos to get you up to speed quickly on how you can run your
own Geth instance.

but we've enumerated a few common parameter combos to get you up to speed quickly
on how you can run your own `geth` instance.
### Full node on the main Ethereum network
By far the most common scenario is people wanting to simply interact with the Ethereum network:
create accounts; transfer funds; deploy and interact with contracts. For this particular use-case
the user doesn't care about years-old historical data, so we can fast-sync quickly to the current
state of the network. To do so:

network: create accounts; transfer funds; deploy and interact with contracts. For this
particular use-case the user doesn't care about years-old historical data, so we can
fast-sync quickly to the current state of the network. To do so:
```
```shell
$ geth console
```
This command will:
* Start geth in fast sync mode (default, can be changed with the `--syncmode` flag), causing it to
download more data in exchange for avoiding processing the entire history of the Ethereum network,
which is very CPU intensive.
* Start up Geth's built-in interactive [JavaScript console](https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console),
* Start `geth` in fast sync mode (default, can be changed with the `--syncmode` flag),

* Start up `geth`'s built-in interactive [JavaScript console](https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console),
(via the trailing `console` subcommand) through which you can invoke all official [`web3` methods](https://github.com/ethereum/wiki/wiki/JavaScript-API)
as well as Geth's own [management APIs](https://github.com/ethereum/go-ethereum/wiki/Management-APIs).
This tool is optional and if you leave it out you can always attach to an already running Geth instance
with `geth attach`.

### Full node on the Ethereum test network
### A Full node on the Ethereum test network
Transitioning towards developers, if you'd like to play around with creating Ethereum contracts, you
almost certainly would like to do that without any real money involved until you get the hang of the
entire system. In other words, instead of attaching to the main network, you want to join the **test**
network with your node, which is fully equivalent to the main network, but with play-Ether only.

testnet too. Please see above for their explanations if you've skipped to here.

Specifying the `--testnet` flag, however, will reconfigure your `geth` instance a bit:
* Instead of using the default data directory (`~/.ethereum` on Linux for example), Geth will nest
itself one level deeper into a `testnet` subfolder (`~/.ethereum/testnet` on Linux). Note, on OSX
and Linux this also means that attaching to a running testnet node requires the use of a custom
endpoint since `geth attach` will try to attach to a production node endpoint by default. E.g.
`geth attach <datadir>/testnet/geth.ipc`. Windows users are not affected by this.
* Instead of connecting the main Ethereum network, the client will connect to the test network,
which uses different P2P bootnodes, different network IDs and genesis states.

*Note: Although there are some internal protective measures to prevent transactions from crossing
over between the main network and test network, you should make sure to always use separate accounts
for play-money and real-money. Unless you manually move accounts, Geth will by default correctly
separate the two networks and will not make any accounts available between them.*

### Full node on the Rinkeby test network
The above test network is a cross client one based on the ethash proof-of-work consensus algorithm. As such, it has certain extra overhead and is more susceptible to reorganization attacks due to the network's low difficulty / security. Go Ethereum also supports connecting to a proof-of-authority based test network called [*Rinkeby*](https://www.rinkeby.io) (operated by members of the community). This network is lighter, more secure, but is only supported by go-ethereum.

#### Docker quick start
One of the quickest ways to get Ethereum up and running on your machine is by using Docker:

Docker:
```
```shell
docker run -d --name ethereum-node -v /Users/alice/ethereum:/root \
-p 8545:8545 -p 30303:30303 \
ethereum/client-go
```
This will start geth in fast-sync mode with a DB memory allowance of 1GB just as the above command does. It will also create a persistent volume in your home directory for saving your blockchain as well as map the default ports. There is also an `alpine` tag available for a slim version of the image.

Do not forget `--rpcaddr 0.0.0.0`, if you want to access RPC from other containers and/or hosts. By default, `geth` binds to the local interface and RPC endpoints is not accessible from the outside.

### Programatically interfacing Geth nodes
### Programmatically interfacing `geth` nodes
As a developer, sooner rather than later you'll want to start interacting with Geth and the Ethereum
network via your own programs and not manually through the console. To aid this, Geth has built-in
support for a JSON-RPC based APIs ([standard APIs](https://github.com/ethereum/wiki/wiki/JSON-RPC) and
[Geth specific APIs](https://github.com/ethereum/go-ethereum/wiki/Management-APIs)). These can be
exposed via HTTP, WebSockets and IPC (unix sockets on unix based platforms, and named pipes on Windows).

These can be exposed via HTTP, WebSockets and IPC (UNIX sockets on UNIX based

The IPC interface is enabled by default and exposes all the APIs supported by Geth, whereas the HTTP
and WS interfaces need to manually be enabled and only expose a subset of APIs due to security reasons.
These can be turned on/off and configured as you'd expect.

* `--ipcpath` Filename for IPC socket/pipe within the datadir (explicit paths escape it)
You'll need to use your own programming environments' capabilities (libraries, tools, etc) to connect
via HTTP, WS or IPC to a Geth node configured with the above flags and you'll need to speak [JSON-RPC](http://www.jsonrpc.org/specification)
on all transports. You can reuse the same connection for multiple requests!

### Operating a private network
Maintaining your own private network is more involved as a lot of configurations taken for granted in
the official networks need to be manually set up.

#### Defining the private genesis state
First, you'll need to create the genesis state of your networks, which all nodes need to be aware of
and agree upon. This consists of a small JSON file (e.g. call it `genesis.json`):

The above fields should be fine for most purposes, although we'd recommend changing the `nonce` to
some random value so you prevent unknown remote nodes from being able to connect to you. If you'd
like to pre-fund some accounts for easier testing, you can populate the `alloc` field with account
configs:

With all nodes that you want to run initialized to the desired genesis state, you'll need to start a
bootstrap node that others can use to find each other in your network and/or over the internet. The
clean way is to configure and run a dedicated bootnode:

```
```shell

$ bootnode --nodekey=boot.key
```
With the bootnode online, it will display an [`enode` URL](https://github.com/ethereum/wiki/wiki/enode-url-format)
that other nodes can use to connect to it and exchange peer information. Make sure to replace the
displayed IP address information (most probably `[::]`) with your externally accessible IP to get the
actual `enode` URL.

*Note: You could also use a full fledged Geth node as a bootnode, but it's the less recommended way.*

#### Starting up your member nodes
With the bootnode operational and externally reachable (you can try `telnet <ip> <port>` to ensure
it's indeed reachable), start every subsequent Geth node pointed to the bootnode for peer discovery
via the `--bootnodes` flag. It will probably also be desirable to keep the data directory of your
private network separated, so do also specify a custom `--datadir` flag.

#### Running a private miner
Mining on the public Ethereum network is a complex task as it's only feasible using GPUs, requiring
an OpenCL or CUDA enabled `ethminer` instance. For information on such a setup, please consult the
[EtherMining subreddit](https://www.reddit.com/r/EtherMining/) and the [Genoil miner](https://github.com/Genoil/cpp-ethereum)
repository.

and the [Genoil miner](https://github.com/Genoil/cpp-ethereum) repository.
In a private network setting however, a single CPU miner instance is more than enough for practical
purposes as it can produce a stable stream of blocks at the correct intervals without needing heavy
resources (consider running on a single thread, no need for multiple ones either). To start a Geth
instance for mining, run it with all your usual flags, extended by:

the account specified by `--etherbase`. You can further tune the mining by changing the default gas
limit blocks converge to (`--targetgaslimit`) and the price transactions are accepted at (`--gasprice`).

# Using the smartcard wallet
## Requirements
* A USB smartcard reader
* A keycard that supports the status app
* PCSCD version 4.3 running on your system **Only version 4.3 is currently supported**
## Preparing the smartcard
**WARNING: FOILLOWING THESE INSTRUCTIONS WILL DESTROY THE MASTER KEY ON YOUR CARD. ONLY PROCEED IF NO FUNDS ARE ASSOCIATED WITH THESE ACCOUNTS**
You can use status' [keycard-cli](https://github.com/status-im/keycard-cli) and you should get _at least_ version 2.1.1 of their [smartcard application](https://github.com/status-im/status-keycard/releases/download/2.2.1/keycard_v2.2.1.cap)
You also need to make sure that the PCSC daemon is running on your system.
Then, you can install the application to the card by typing:
```
keycard install -a keycard_v2.2.1.cap && keycard init
```
At the end of this process, you will be provided with a PIN, a PUK and a pairing password. Write them down, you'll need them shortly.
Start `geth` with the `console` command. You will notice the following warning:
```
WARN [04-09|16:58:38.898] Failed to open wallet url=keycard://044def09 err="smartcard: pairing password needed"
```
Write down the URL (`keycard://044def09` in this example). Then ask `geth` to open the wallet:
```
> personal.openWallet("keycard://044def09")
Please enter the pairing password:
```
Enter the pairing password that you have received during card initialization. Same with the PIN that you will subsequently be
asked for.
If everything goes well, you should see your new account when typing `personal` on the console:
```
> personal
WARN [04-09|17:02:07.330] Smartcard wallet account derivation failed url=keycard://044def09 err="Unexpected response status Cla=0x80, Ins=0xd1, Sw=0x6985"
{
listAccounts: [],
listWallets: [{
status: "Empty, waiting for initialization",
url: "keycard://044def09"
}],
...
}
```
So the communication with the card is working, but there is no key associated with this wallet. Let's create it:
```
> personal.initializeWallet("keycard://044def09")
"tilt ... impact"
```
You should get a list of words, this is your seed so write them down. Your wallet should now be initialized:
```
> personal.listWallets
[{
accounts: [{
address: "0x678b7cd55c61917defb23546a41803c5bfefbc7a",
url: "keycard://044d/m/44'/60'/0'/0/0"
}],
status: "Online",
url: "keycard://044def09"
}]
```
You're all set!
## Usage
1. Start `geth` with the `console` command
2. Check the card's URL by checking `personal.listWallets`:
```
listWallets: [{
status: "Online, can derive public keys",
url: "keycard://a4d73015"
}]
```
3. Open the wallet, you will be prompted for your pairing password, then PIN:
```
personal.openWallet("keycard://a4d73015")
```
4. Check that creation was successful by typing e.g. `personal`. Then use it like a regular wallet.
## Known issues
* Starting geth with a valid card seems to make firefox crash.
* PCSC version 4.4 should work, but is currently untested

// Before you touch the protocol files, you need to be aware of a breaking change
// that occurred between firmware versions 1.7.3->1.8.0 (Model One) and 2.0.10->
// 2.1.0 (Model T). The Ethereum address representation was changed from the 20
// byte binary blob to a 42 byte hex string. The upstream protocol buffer files
// only support the new format, so blindly pulling in a new spec will break old
// devices!
//
// The Trezor devs had the foresight to add the string version as a new message
// code instead of replacing the binary one. This means that the proto file can
// actually define both the old and the new versions as optional. Please ensure
// that you add back the old addresses everywhere (to avoid name clash. use the
// addressBin and addressHex names).
//
// If in doubt, reach out to @karalabe.
// To regenerate the protocol files in this package:
// - Download the latest protoc https://github.com/protocolbuffers/protobuf/releases
// - Build with the usual `./configure && make` and ensure it's on your $PATH
// - Delete all the .proto and .pb.go files, pull in fresh ones from Trezor
// - Grab the latest Go plugin `go get -u github.com/golang/protobuf/protoc-gen-go`
// - Vendor in the latest Go plugin `govendor fetch github.com/golang/protobuf/...`

Packages of develop branch commits have suffix -unstable and cannot be installed alongside
the stable version. Switching between release streams requires user intervention.
## Launchpad
The packages are built and served by launchpad.net. We generate a Debian source package
for each distribution and upload it. Their builder picks up the source package, builds it
and installs the new version into the PPA repository. Launchpad requires a valid signature
by a team member for source package uploads. The signing key is stored in an environment
variable which Travis CI makes available to certain builds.
by a team member for source package uploads.
The signing key is stored in an environment variable which Travis CI makes available to
certain builds. Since Travis CI doesn't support FTP, SFTP is used to transfer the
packages. To set this up yourself, you need to create a Launchpad user and add a GPG key
and SSH key to it. Then encode both keys as base64 and configure 'secret' environment
variables `PPA_SIGNING_KEY` and `PPA_SSH_KEY` on Travis.
We want to build go-ethereum with the most recent version of Go, irrespective of the Go
version that is available in the main Ubuntu repository. In order to make this possible,
our PPA depends on the ~gophers/ubuntu/archive PPA. Our source package build-depends on
golang-1.10, which is co-installable alongside the regular golang package. PPA dependencies
golang-1.11, which is co-installable alongside the regular golang package. PPA dependencies
can be edited at https://launchpad.net/%7Eethereum/+archive/ubuntu/ethereum/+edit-dependencies
## Building Packages Locally (for testing)
You need to run Ubuntu to do test packaging.
Add the gophers PPA and install Go 1.10 and Debian packaging tools:

## UI Client interface
These data types are defined in the channel between clef and the UI
### SignDataRequest
SignDataRequest contains information about a pending request to sign some data. The data to be signed can be of various types, defined by content-type. Clef has done most of the work in canonicalizing and making sense of the data, and it's up to the UI to presentthe user with the contents of the `message`
Example:
```json
{
"content_type": "text/plain",
"address": "0xDEADbEeF000000000000000000000000DeaDbeEf",
"raw_data": "GUV0aGVyZXVtIFNpZ25lZCBNZXNzYWdlOgoxMWhlbGxvIHdvcmxk",
"message": [
{
"name": "message",
"value": "\u0019Ethereum Signed Message:\n11hello world",
"type": "text/plain"
}
],
"hash": "0xd9eba16ed0ecae432b71fe008c98cc872bb4cc214d3220a36f365326cf807d68",
"meta": {
"remote": "localhost:9999",
"local": "localhost:8545",
"scheme": "http",
"User-Agent": "Firefox 3.2",
"Origin": "www.malicious.ru"
}
}
```
### SignDataResponse - approve
Response to SignDataRequest
Example:
```json
{
"approved": true
}
```
### SignDataResponse - deny
Response to SignDataRequest
Example:
```json
{
"approved": false
}
```
### SignTxRequest
SignTxRequest contains information about a pending request to sign a transaction. Aside from the transaction itself, there is also a `call_info`-struct. That struct contains messages of various types, that the user should be informed of.
As in any request, it's important to consider that the `meta` info also contains untrusted data.
The `transaction` (on input into clef) can have either `data` or `input` -- if both are set, they must be identical, otherwise an error is generated. However, Clef will always use `data` when passing this struct on (if Clef does otherwise, please file a ticket)
Example:
```json
{
"transaction": {
"from": "0xDEADbEeF000000000000000000000000DeaDbeEf",
"to": null,
"gas": "0x3e8",
"gasPrice": "0x5",
"value": "0x6",
"nonce": "0x1",
"data": "0x01020304"
},
"call_info": [
{
"type": "Warning",
"message": "Something looks odd, show this message as a warning"
},
{
"type": "Info",
"message": "User should see this aswell"
}
],
"meta": {
"remote": "localhost:9999",
"local": "localhost:8545",
"scheme": "http",
"User-Agent": "Firefox 3.2",
"Origin": "www.malicious.ru"
}
}
```
### SignTxResponse - approve
Response to request to sign a transaction. This response needs to contain the `transaction`, because the UI is free to make modifications to the transaction.
Example:
```json
{
"transaction": {
"from": "0xDEADbEeF000000000000000000000000DeaDbeEf",
"to": null,
"gas": "0x3e8",
"gasPrice": "0x5",
"value": "0x6",
"nonce": "0x4",
"data": "0x04030201"
},
"approved": true
}
```
### SignTxResponse - deny
Response to SignTxRequest. When denying a request, there's no need to provide the transaction in return
Example:
```json
{
"transaction": {
"from": "0x",
"to": null,
"gas": "0x0",
"gasPrice": "0x0",
"value": "0x0",
"nonce": "0x0",
"data": null
},
"approved": false
}
```
### OnApproved - SignTransactionResult
SignTransactionResult is used in the call `clef` -> `OnApprovedTx(result)`
This occurs _after_ successful completion of the entire signing procedure, but right before the signed transaction is passed to the external caller. This method (and data) can be used by the UI to signal to the user that the transaction was signed, but it is primarily useful for ruleset implementations.
A ruleset that implements a rate limitation needs to know what transactions are sent out to the external interface. By hooking into this methods, the ruleset can maintain track of that count.
**OBS:** Note that if an attacker can restore your `clef` data to a previous point in time (e.g through a backup), the attacker can reset such windows, even if he/she is unable to decrypt the content.
The `OnApproved` method cannot be responded to, it's purely informative
Example:
```json
{
"raw": "0xf85d640101948a8eafb1cf62bfbeb1741769dae1a9dd47996192018026a0716bd90515acb1e68e5ac5867aa11a1e65399c3349d479f5fb698554ebc6f293a04e8a4ebfff434e971e0ef12c5bf3a881b06fd04fc3f8b8a7291fb67a26a1d4ed",

}
}
```
### UserInputRequest
Sent when clef needs the user to provide data. If 'password' is true, the input field should be treated accordingly (echo-free)
Example:
```json
{
"prompt": "The question to ask the user",
"title": "The title here",
"isPassword": true
}
```
### UserInputResponse
Response to UserInputRequest
Example:
```json
{
"text": "The textual response from user"
}
```
### ListRequest
Sent when a request has been made to list addresses. The UI is provided with the full `account`s, including local directory names. Note: this information is not passed back to the external caller, who only sees the `address`es.
Example:
```json
{
"accounts": [
{
"address": "0xdeadbeef000000000000000000000000deadbeef",
"url": "keystore:///path/to/keyfile/a"
},
{
"address": "0x1111111122222222222233333333334444444444",
"url": "keystore:///path/to/keyfile/b"
}
],
"meta": {
"remote": "localhost:9999",
"local": "localhost:8545",
"scheme": "http",
"User-Agent": "Firefox 3.2",
"Origin": "www.malicious.ru"
}
}
```
### ListResponse
Response to list request. The response contains a list of all addresses to show to the caller. Note: the UI is free to respond with any address the caller, regardless of whether it exists or not
Example:
```json
{
"accounts": [
{
"address": "0x0000000000000000000000000000000000000000",
"url": ".. ignored .."
},
{
"address": "0xffffffffffffffffffffffffffffffffffffffff",
"url": ""
}
]

### Changelog for external API
### 6.0.0
* `New` was changed to deliver only an address, not the full `Account` data
* `Export` was moved from External API to the UI Server API
#### 5.0.0
* The external `account_EcRecover`-method was reimplemented.
* The external method `account_sign(address, data)` was replaced with `account_signData(contentType, address, data)`.
The addition of `contentType` makes it possible to use the method for different types of objects, such as:
* signing data with an intended validator (not yet implemented)
* signing clique headers,
* signing plain personal messages,
* The external method `account_signTypedData` implements [EIP-712](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md) and makes it possible to sign typed data.
#### 4.0.0
* The external `account_Ecrecover`-method was removed.

### Changelog for internal API (ui-api)
### 6.0.0
Removed `password` from responses to operations which require them. This is for two reasons,
- Consistency between how rulesets operate and how manual processing works. A rule can `Approve` but require the actual password to be stored in the clef storage.
With this change, the same stored password can be used even if rulesets are not enabled, but storage is.
- It also removes the usability-shortcut that a UI might otherwise want to implement; remembering passwords. Since we now will not require the
password on every `Approve`, there's no need for the UI to cache it locally.
- In a future update, we'll likely add `clef_storePassword` to the internal API, so the user can store it via his UI (currently only CLI works).
Affected datatypes:
- `SignTxResponse`
- `SignDataResponse`
- `NewAccountResponse`
If `clef` requires a password, the `OnInputRequired` will be used to collect it.
### 5.0.0
Changed the namespace format to adhere to the legacy ethereum format: `name_methodName`. Changes:
* `ApproveTx` -> `ui_approveTx`
* `ApproveSignData` -> `ui_approveSignData`
* `ApproveExport` -> `removed`
* `ApproveImport` -> `removed`
* `ApproveListing` -> `ui_approveListing`
* `ApproveNewAccount` -> `ui_approveNewAccount`
* `ShowError` -> `ui_showError`
* `ShowInfo` -> `ui_showInfo`
* `OnApprovedTx` -> `ui_onApprovedTx`
* `OnSignerStartup` -> `ui_onSignerStartup`
* `OnInputRequired` -> `ui_onInputRequired`
### 4.0.0
* Bidirectional communication implemented, so the UI can query `clef` via the stdin/stdout RPC channel. Methods implemented are:
- `clef_listWallets`
- `clef_listAccounts`
- `clef_listWallets`
- `clef_deriveAccount`
- `clef_importRawKey`
- `clef_openWallet`
- `clef_chainId`
- `clef_setChainId`
- `clef_export`
- `clef_import`
* The type `Account` was modified (the json-field `type` was removed), to consist of
```golang
type Account struct {
Address common.Address `json:"address"` // Ethereum account address derived from the key
URL URL `json:"url"` // Optional resource locator within a backend
}
```
### 3.2.0
* Make `ShowError`, `OnApprovedTx`, `OnSignerStartup` be json-rpc [notifications](https://www.jsonrpc.org/specification#notification):
> A Notification is a Request object without an "id" member. A Request object that is a Notification signifies the Client's lack of interest in the corresponding Response object, and as such no Response object needs to be returned to the client. The Server MUST NOT reply to a Notification, including those that are within a batch request.
>
> Notifications are not confirmable by definition, since they do not have a Response object to be returned. As such, the Client would not be aware of any errors (like e.g. "Invalid params","Internal error"
### 3.1.0
* Add `ContentType` `string` to `SignDataRequest` to accommodate the latest EIP-191 and EIP-712 implementations.
### 3.0.0
* Make use of `OnInputRequired(info UserInputRequest)` for obtaining master password during startup
