title: Getting Started with Nimbus
|
|
---
|
|
|
|
This document will explain how to install, test, and run Nimbus on your local machine. To learn about what Nimbus is, see the [intro post](https://our.status.im/nimbus-for-newbies/).
|
|
|
|
### Building and Running Nimbus
|
|
|
|
To run Nimbus in Ethereum 1.0 mode:
|
|
|
|
```bash
|
|
git clone https://github.com/status-im/nimbus
|
|
cd nimbus
|
|
make update
|
|
|
|
# >>> WINDOWS ONLY <<<
|
|
make fetch-dlls # WINDOWS ONLY
|
|
# >>> WINDOWS ONLY <<<
|
|
|
|
make nimbus
|
|
./build/nimbus
|
|
```
|
|
|
|
Nimbus will now run and attempt to synchronize with the Ethereum 1.0 blockchain. It can currently reach block 1.5 million.
|
|
|
|
### Building and Running the Ethereum 2.0 local beacon chain simulation
|
|
|
|
The beacon chain simulation runs several beacon nodes on the local machine, attaches several local validators to each, and builds a beacon chain between them. This is a precursor to our [testnet](https://our.status.im/the-nimbus-mvp-testnet-is-here/).
|
|
|
|
Prerequisites: Golang 1.12+, because we need it to build the Go libp2p daemon for node communication. You also need `git-lfs` installed to run tests - on Windows that's a command documented below, on other operating systems it can be installed using your system's package manager (e.g. `sudo apt-get install git-lfs`).
|
|
|
|
Enter the Ethereum 2.0 realm of Nimbus:
|
|
|
|
```bash
|
|
git clone https://github.com/status-im/nim-beacon-chain
|
|
cd nim-beacon-chain
|
|
|
|
# >>> WINDOWS ONLY <<<
|
|
make fetch-dlls # WINDOWS ONLY
|
|
# >>> WINDOWS ONLY <<<
|
|
|
|
make
|
|
make test
|
|
```
|
|
|
|
To run the simulation:
|
|
|
|
```bash
|
|
make eth2_network_simulation
|
|
```
|
|
|
|
If you'd like to clean the previous run's data:
|
|
|
|
```bash
|
|
make clean_eth2_network_simulation_files eth2_network_simulation
|
|
```
|
|
|
|
If you'd like to see the nodes running on separated sub-terminals inside one big window, install [Multitail](https://www.vanheusden.com/multitail/), then:
|
|
|
|
```bash
|
|
USE_MULTITAIL="yes" make eth2_network_simulation
|
|
```
|
|
|
|
You'll get something like this (click for full size):

|
|
|
|
To change the number of validators and nodes:
|
|
|
|
```bash
|
|
VALIDATORS=512 NODES=50 make eth2_network_simulation
|
|
```
|
|
|
|
Find out more about the simulation [here](https://our.status.im/nimbus-development-update-03/).
|
|
|
|
### Building and Running the Ethereum 2.0 local state transition simulation
|
|
|
|
The state transition simulation measures how fast it can process the tasks in the beacon chain's state transition.
|
|
|
|
```bash
|
|
cd research
|
|
nim c -d:release -r state_sim --help
|
|
```
|
|
|
|
Use the output of the help command to pass desired values to the sim - change number of validators, nodes, etc. to get different results.
|
|
|
|
### Nimbus Ethereum 2.0 Testnet
|
|
|
|
We have a publicly available testnet running between Nimbus nodes. Read all about it and learn how you can join it [here](/docs/t0.html). There is also a cutting edge [testnet 1](/docs/t1.html) that's basically a testing ground for testnet 0.

Congrats! You're now running Nimbus for both the Ethereum 1.0 platform, and the coming [Ethereum 2.0](https://our.status.im/tag/two-point-oh). |
