|
||||
|
||||
The `beacon_node` and `validator` commands have a `testnet` sub-command to
|
||||
allow creating or connecting to Eth2 beacon chain testnets.
|
||||
It is possible to create local, short-lived Lighthouse testnets that _don't_
|
||||
require a deposit contract and Eth1 connection. There are two components
|
||||
required for this:
|
||||
|
||||
For detailed documentation, use the `--help` flag on the CLI:
|
||||
1. Creating a "testnet directory", containing the configuration of your new
|
||||
testnet.
|
||||
1. Using the `--dummy-eth1` flag on your beacon node to avoid needing an Eth1
|
||||
node for block production.
|
||||
|
||||
There is a TL;DR (too long; didn't read), followed by detailed steps if the
|
||||
TL;DR isn't adequate.
|
||||
|
||||
## TL;DR
|
||||
|
||||
```bash
|
||||
$ lighthouse bn testnet --help
|
||||
lcli new-testnet
|
||||
lcli interop-genesis 128
|
||||
lighthouse bn --testnet-dir ~/.lighthouse/testnet --dummy-eth1 --http
|
||||
lighthouse vc --testnet-dir ~/.lighthouse/testnet --allow-unsynced testnet insecure 0 128
|
||||
```
|
||||
|
||||
Optionally update the genesis time to now:
|
||||
|
||||
```bash
|
||||
$ lighthouse vc testnet --help
|
||||
lcli change-genesis-time ~/.lighthouse/testnet/genesis.ssz $(date +%s)
|
||||
```
|
||||
|
||||
## Examples
|
||||
## 1. Creating a testnet directory
|
||||
|
||||
All examples assume a working [development environment](./setup.md) and
|
||||
commands are based in the `target/release` directory (this is the build dir for
|
||||
`cargo`).
|
||||
### 1.1 Install `lcli`
|
||||
|
||||
### Start a beacon node given a validator count and genesis_time
|
||||
This guide requires `lcli`, the "Lighthouse CLI tool". It is a development tool
|
||||
used for starting testnets and debugging.
|
||||
|
||||
|
||||
To start a brand-new beacon node (with no history) use:
|
||||
Install `lcli` from the root directory of this repository with:
|
||||
|
||||
```bash
|
||||
$ lighthouse bn testnet -f quick 8 <GENESIS_TIME>
|
||||
cargo install --path lcli --force
|
||||
```
|
||||
|
||||
Where `GENESIS_TIME` is in [unix time](https://duckduckgo.com/?q=unix+time&t=ffab&ia=answer).
|
||||
### 1.2 Create a testnet directory
|
||||
|
||||
> Notes:
|
||||
>
|
||||
> - This method conforms the ["Quick-start
|
||||
genesis"](https://github.com/ethereum/eth2.0-pm/tree/6e41fcf383ebeb5125938850d8e9b4e9888389b4/interop/mocked_start#quick-start-genesis)
|
||||
method in the `ethereum/eth2.0-pm` repository.
|
||||
> - The `-f` flag ignores any existing database or configuration, backing them
|
||||
> up before re-initializing.
|
||||
> - `8` is the validator count and `1567222226` is the genesis time.
|
||||
> - See `$ lighthouse bn testnet quick --help` for more configuration options.
|
||||
The default location for a testnet directory is `~/.lighthouse/testnet`. We'll
|
||||
use this directory to keep the examples simple, however you can always specify
|
||||
a different directory using the `--testnet-dir` flag.
|
||||
|
||||
### Start a beacon node given a genesis state file
|
||||
|
||||
A genesis state can be read from file using the `testnet file` subcommand.
|
||||
There are three supported formats:
|
||||
|
||||
- `ssz` (default)
|
||||
- `json`
|
||||
- `yaml`
|
||||
|
||||
Start a new node using `/tmp/genesis.ssz` as the genesis state:
|
||||
Once you have `lcli` installed, create a new testnet directory with:
|
||||
|
||||
```bash
|
||||
$ lighthouse bn testnet --spec minimal -f file ssz /tmp/genesis.ssz
|
||||
lcli new-testnet
|
||||
```
|
||||
|
||||
> Notes:
|
||||
>
|
||||
> - The `-f` flag ignores any existing database or configuration, backing them
|
||||
> up before re-initializing.
|
||||
> - See `$ lighthouse bn testnet file --help` for more configuration options.
|
||||
> - The `--spec` flag is required to allow SSZ parsing of fixed-length lists.
|
||||
> Here the `minimal` eth2 specification is chosen, allowing for lower
|
||||
> validator counts. See
|
||||
> [eth2.0-specs/configs](https://github.com/ethereum/eth2.0-specs/tree/dev/configs)
|
||||
> for more info.
|
||||
> - This will create a "mainnet" spec testnet. To create a minimal spec use `lcli --spec minim new-testnet`.
|
||||
> - The `lcli new-testnet` command has many options, use `lcli new-testnet --help` to see them.
|
||||
|
||||
### Start an auto-configured validator client
|
||||
### 1.3 Create a genesis state
|
||||
|
||||
To start a brand-new validator client (with no history) use:
|
||||
Your new testnet directory at `~/.lighthouse/testnet` doesn't yet have a
|
||||
genesis state (`genesis.ssz`). Since there's no deposit contract in this
|
||||
testnet, there's no way for nodes to find genesis themselves.
|
||||
|
||||
Manually create an "interop" genesis state with `128` validators:
|
||||
|
||||
```bash
|
||||
$ lighthouse vc testnet insecure 0 8
|
||||
lcli interop-genesis 128
|
||||
```
|
||||
|
||||
> Notes:
|
||||
>
|
||||
> - The `insecure` command dictates that the [interop keypairs](https://github.com/ethereum/eth2.0-pm/tree/6e41fcf383ebeb5125938850d8e9b4e9888389b4/interop/mocked_start#pubkeyprivkey-generation)
|
||||
> will be used.
|
||||
> - The `0 8` indicates that this validator client should manage 8 validators,
|
||||
> starting at validator 0 (the first deposited validator).
|
||||
> - The validator client will try to connect to the beacon node at `localhost`.
|
||||
> See `--help` to configure that address and other features.
|
||||
> - The validator client will operate very unsafely in `testnet` mode, happily
|
||||
> swapping between chains and creating double-votes.
|
||||
> - A custom genesis time can be provided with `-t`.
|
||||
> - See `lcli interop-genesis --help` for more info.
|
||||
|
||||
### Exporting a genesis file
|
||||
## 2. Start the beacon nodes and validator clients
|
||||
|
||||
Genesis states can downloaded from a running Lighthouse node via the HTTP API. Three content-types are supported:
|
||||
Now the testnet has been specified in `~/.lighthouse/testnet`, it's time to
|
||||
start a beacon node and validator client.
|
||||
|
||||
- `application/json`
|
||||
- `application/yaml`
|
||||
- `application/ssz`
|
||||
### 2.1 Start a beacon node
|
||||
|
||||
Using `curl`, a genesis state can be downloaded to `/tmp/genesis.ssz`:
|
||||
Start a beacon node:
|
||||
|
||||
```bash
|
||||
$ curl --header "Content-Type: application/ssz" "localhost:5052/beacon/state/genesis" -o /tmp/genesis.ssz
|
||||
lighthouse bn --testnet-dir ~/.lighthouse/testnet --dummy-eth1 --http
|
||||
```
|
||||
|
||||
## Advanced
|
||||
> - `--testnet-dir` instructs the beacon node to use the spec we generated earlier.
|
||||
> - `--dummy-eth1` uses deterministic "junk data" for linking to the eth1 chain, avoiding the requirement for an eth1 node. The downside is that new validators cannot be on-boarded after genesis.
|
||||
> - `--http` starts the REST API so the validator client can produce blocks.
|
||||
|
||||
Below are some CLI commands useful when working with testnets.
|
||||
### 2.2 Start a validator client
|
||||
|
||||
### Specify a boot node by multiaddr
|
||||
|
||||
You can specify a static list of multiaddrs when booting Lighthouse using
|
||||
the `--libp2p-addresses` command.
|
||||
|
||||
#### Example:
|
||||
Once the beacon node has started and begun trying to sync, start a validator
|
||||
client:
|
||||
|
||||
```bash
|
||||
$ lighthouse bn --libp2p-addresses /ip4/192.168.0.1/tcp/9000
|
||||
lighthouse vc --testnet-dir ~/.lighthouse/testnet --allow-unsynced testnet insecure 0 128
|
||||
```
|
||||
|
||||
### Specify a boot node by ENR (Ethereum Name Record)
|
||||
|
||||
You can specify a static list of Discv5 addresses when booting Lighthouse using
|
||||
the `--boot-nodes` command.
|
||||
|
||||
#### Example:
|
||||
|
||||
```bash
|
||||
$ lighthouse bn --boot-nodes -IW4QB2Hi8TPuEzQ41Cdf1r2AUU1FFVFDBJdJyOkWk2qXpZfFZQy2YnJIyoT_5fnbtrXUouoskmydZl4pIg90clIkYUDgmlwhH8AAAGDdGNwgiMog3VkcIIjKIlzZWNwMjU2azGhAjg0-DsTkQynhJCRnLLttBK1RS78lmUkLa-wgzAi-Ob5
|
||||
```
|
||||
|
||||
### Start a testnet with a custom slot time
|
||||
|
||||
Lighthouse can run at quite low slot times when there are few validators (e.g.,
|
||||
`500 ms` slot times should be fine for 8 validators).
|
||||
|
||||
#### Example:
|
||||
|
||||
The `-t` (`--slot-time`) flag specifies the milliseconds per slot.
|
||||
|
||||
```bash
|
||||
$ lighthouse bn testnet -t 500 recent 8
|
||||
```
|
||||
|
||||
> Note: `bootstrap` loads the slot time via HTTP and therefore conflicts with
|
||||
> this flag.
|
||||
> - `--testnet-dir` instructs the validator client to use the spec we generated earlier.
|
||||
> - `--allow-unsynced` stops the validator client checking to see if the beacon node is synced prior to producing blocks.
|
||||
> - `testnet insecure 0 128` instructs the validator client to use insecure
|
||||
> testnet private keys and that it should control validators from `0` to
|
||||
> `127` (inclusive).

Then, get the current unix time in seconds; you can use
|
||||
[epochconverter.com](https://www.epochconverter.com/) or `$ date +%s`. It
|
||||
should look like this `1576803034` and you should use it wherever we put
|
||||
`<time>`.
|
||||
|
||||
> If you choose a time that's more than several minutes in the past the
|
||||
> validator client will refuse to produce blocks. We will loosen this
|
||||
> restriction in the future, the issue is tracked
|
||||
> [here](https://github.com/sigp/lighthouse/issues/714).
|
||||
|
||||
## Starting a beacon node
|
||||
|
||||
Start a new node with:
|
||||
|
||||
```bash
|
||||
$ lighthouse bn --http testnet -r quick 8 <time>
|
||||
```
|
||||
|
||||
> Notes:
|
||||
>
|
||||
> - The `--http` flag starts the API so the validator can produce blocks.
|
||||
> - The `-r` flag creates a random data directory to avoid clashes with other
|
||||
> nodes.
|
||||
> - `8` is number of validators with deposits in the genesis state.
|
||||
> - See `$ lighthouse bn testnet --help` for more configuration options,
|
||||
> including `minimal`/`mainnet` specification.
|
||||
|
||||
## Starting a validator client
|
||||
|
||||
In a new terminal window, start the validator client with:
|
||||
|
||||
```bash
|
||||
$ lighthouse vc testnet insecure 0 8
|
||||
```
|
||||
|
||||
> Notes:
|
||||
>
|
||||
> - The `insecure` command uses predictable, well-known private keys. Since
|
||||
> this is just a local testnet, these are fine.
|
||||
> - The `0 8` indicates that this validator client should manage 8 validators,
|
||||
> starting at validator 0 (the first deposited validator).
|
||||
> - The validator client will try to connect to the beacon node at `localhost`.
|
||||
> See `--help` to configure that address and other features.
|
||||
|
||||
## Adding another beacon node
|
||||
|
||||
You may connect another (non-validating) node to your local network by starting
|
||||
a new terminal and running:
|
||||
|
||||
|
||||
```bash
|
||||
lighthouse bn -z --libp2p-addresses /ip4/127.0.0.1/tcp/9000 testnet -r quick 8 <time>
|
||||
```
|
||||
|
||||
> Notes:
|
||||
>
|
||||
> - The `z` (or `--zero-ports`) flag sets all listening ports to be zero, which then
|
||||
> means that the OS chooses random available ports. This avoids port
|
||||
> collisions with the first node.
|
||||
> - The `--libp2p-addresses` flag instructs the new node to connect to the
|
||||
> first node.
