# Prysm Client Interoperability Guide
|
|
|
|
This README details how to setup Prysm for interop testing for usage with other Ethereum 2.0 clients.
|
|
|
|
## Installation & Setup
|
|
|
|
1. Install [Bazel](https://docs.bazel.build/versions/master/install.html) **(Recommended)**
|
|
2. `git clone https://github.com/prysmaticlabs/prysm && cd prysm`
|
|
3. `bazel build //...`
|
|
|
|
## Starting from Genesis
|
|
|
|
Prysm supports a few ways to quickly launch a beacon node from basic configurations:
|
|
|
|
- `NumValidators + GenesisTime`: Launches a beacon node by deterministically generating a state from a num-validators flag along with a genesis time **(Recommended)**
|
|
- `SSZ Genesis`: Launches a beacon node from a .ssz file containing a SSZ-encoded, genesis beacon state
|
|
|
|
## Generating a Genesis State
|
|
|
|
To setup the necessary files for these quick starts, Prysm provides a tool to generate a `genesis.ssz` from
|
|
a deterministically generated set of validator private keys following the official interop YAML format
|
|
[here](https://github.com/ethereum/eth2.0-pm/blob/master/interop/mocked_start).
|
|
|
|
You can use `bazel run //tools/genesis-state-gen` to create a deterministic genesis state for interop.
|
|
|
|
### Usage
|
|
|
|
- **--genesis-time** uint: Unix timestamp used as the genesis time in the generated genesis state (defaults to now)
|
|
- **--mainnet-config** bool: Select whether genesis state should be generated with mainnet or minimal (default) params
|
|
- **--num-validators** int: Number of validators to deterministically include in the generated genesis state
|
|
- **--output-ssz** string: Output filename of the SSZ marshaling of the generated genesis state
|
|
|
|
The example below creates 64 validator keys, instantiates a genesis state with those 64 validators and with genesis unix timestamp 1567542540,
|
|
and finally writes a ssz encoded output to ~/Desktop/genesis.ssz. This file can be used to kickstart the beacon chain in the next section.
|
|
|
|
```
|
|
bazel run //tools/genesis-state-gen -- --output-ssz ~/Desktop/genesis.ssz --num-validators 64 --genesis-time 1567542540
|
|
```
|
|
|
|
## Launching a Beacon Node + Validator Client
|
|
|
|
### Launching from Pure CLI Flags
|
|
|
|
Open up two terminal windows, run:
|
|
|
|
```
|
|
bazel run //beacon-chain -- \
|
|
--bootstrap-node= \
|
|
--deposit-contract $(curl -s https://prylabs.net/contract) \
|
|
--force-clear-db \
|
|
--interop-num-validators 64 \
|
|
--interop-eth1data-votes
|
|
```
|
|
|
|
This will deterministically generate a beacon genesis state and start
|
|
the system with 64 validators and the genesis time set to the current unix timestamp.
|
|
Wait a bit until your beacon chain starts, and in the other window:
|
|
|
|
```
|
|
bazel run //validator -- --keymanager=interop --keymanageropts='{"keys":64}'
|
|
```
|
|
|
|
This will launch and kickstart the system with your 64 validators performing their duties accordingly.
|
|
|
|
### Launching from `genesis.ssz`
|
|
|
|
Assuming you generated a `genesis.ssz` file with 64 validators, open up two terminal windows, run:
|
|
|
|
```
|
|
bazel run //beacon-chain -- \
|
|
--bootstrap-node= \
|
|
--deposit-contract $(curl -s https://prylabs.net/contract) \
|
|
--force-clear-db \
|
|
--interop-genesis-state /path/to/genesis.ssz \
|
|
--interop-eth1data-votes
|
|
```
|
|
|
|
Wait a bit until your beacon chain starts, and in the other window:
|
|
|
|
```
|
|
bazel run //validator -- --keymanager=interop --keymanageropts='{"keys":64}'
|
|
```
|
|
|
|
This will launch and kickstart the system with your 64 validators performing their duties accordingly.
