Geth is the program that communicates with the Ethereum Network and acts as the a relay between your computer, its hardware and the rest of the ethereum network computers so if a block is mined by another computer your Geth program will pick it up and then pass on the new information onto your GPU or CPU for mining.
Quickly setup a local, private Ethereum blockchain.
Features:
- Programmatic as well as command-line interface
- Automatically enables IPC and RPC/CORS access
- Override all options passed to the
geth
executable. - Execute console commands against the running geth instance.
- Logging capture
- Works with Mist wallet
Requirements:
- Node.js v4 or above
Installation
I recommend installing geth-private as a global module so that the CLI becomesavailable in your PATH:
Usage
via command-line
Quickstart
You should see something like:
Note: geth-private runs Geth on port 60303 (and HTTP RPC on port 58545) by default with networkid 33333
Run the
attach
command given to attach a console to this running gethinstance. By default web3 RPC is alsoenabled on port 58545.Once it's running launch the Ethereum/Mist wallet with the
--rpc http://localhost:58545
CLI option - it should be able toconnect to your geth instance.Options
You can also pass options directly to geth. For example, you can customizenetwork identity, port, etc:
By default geth-private stores its keystore and blockchain data inside atemporarily generated folder, which gets automatically deleted once it exits.You can override this behaviour by providing a custom location using the
datadir
option:When geth-private exits it won't auto-delete this data folder since youmanually specified it. This allows you to re-use once created keys andaccounts easily.
via API
Same as for the CLI, you can customize it by passing options during construction:
You can execute web3 commands against the running geth instance: Guitar pro 6 soundbanks download.
Mining
To start and stop mining:
If you've never mined before then Geth will first generate a DAG, whichcould take a while. Use the
-v
option to Geth's logging.Logging capture
When using the programmatic API you can capture all output logging by passinga custom logging object:
Development
