# Configuring a Network for Private Transactions
|
|
|
|
|
|
Configuring a network that supports private transactions requires starting an Orion node for each
|
|
|
Pantheon node. Pantheon command line options associate the Pantheon node with the Orion node.
|
|
|
|
|
|
This tutorial assumes you have completed setting up an IBFT 2.0 network to the point where you have
|
|
|
[created the genesis file](../Tutorials/Create-IBFT-Network.md#5-create-genesis-file). If not, complete
|
|
|
steps 1 to 5 of the [Create an IBFT 2.0](../Tutorials/Create-IBFT-Network.md) tutorial before continuing.
|
|
|
|
|
|
In this tutorial we start Orion nodes for the three Pantheon nodes and configure each Pantheon node to be associated
|
|
|
with an Orion node.
|
|
|
|
|
|
## 1. Create Orion Directories
|
|
|
|
|
|
Inside each `Node` directory, create an `Orion` directory:
|
|
|
|
|
|
```bash
|
|
|
IBFT-Network/
|
|
|
├── Node-1
|
|
|
│ ├── data
|
|
|
│ ├── Orion
|
|
|
├── Node-2
|
|
|
│ ├── data
|
|
|
│ ├── Orion
|
|
|
└── Node-3
|
|
|
├── data
|
|
|
├── Orion
|
|
|
```
|
|
|
|
|
|
## 2. Create Password Files
|
|
|
|
|
|
In each `Orion` directory, create a file called `passwordFile` containing a password to encrypt each Orion key pair.
|
|
|
|
|
|
## 3. Generate Orion Keys
|
|
|
|
|
|
In each `Orion` directory, generate a public/private keypair for the Orion node:
|
|
|
|
|
|
``` bash
|
|
|
orion -g nodeKey
|
|
|
```
|
|
|
|
|
|
At the prompt, enter the [password](#2-create-password-files) saved in `passwordFile` to encrypt the key pair.
|
|
|
|
|
|
The Orion public/private key pair is generated and the keys saved in the `nodeKey.pub` and `nodeKey.key` files.
|
|
|
|
|
|
## 4. Create Orion Configuration Files
|
|
|
|
|
|
In the `Node-1/Orion` directory, create a file called `orion.conf` and add the following properties:
|
|
|
|
|
|
```bash
|
|
|
nodeurl = "http://127.0.0.1:8080/"
|
|
|
nodeport = 8080
|
|
|
clienturl = "http://127.0.0.1:8888/"
|
|
|
clientport = 8888
|
|
|
publickeys = ["nodeKey.pub"]
|
|
|
privatekeys = ["nodeKey.key"]
|
|
|
passwords = "passwordFile"
|
|
|
tls = "off"
|
|
|
```
|
|
|
|
|
|
!!! important
|
|
|
In production systems, only specify [`tls`](http://docs.orion.pegasys.tech/en/latest/Configuring-Orion/Configuration-File/#tls)
|
|
|
is `off` if another transport security mechanism such as WireGuard is in place.
|
|
|
|
|
|
In the `Node-2/Orion` and `Node-3/Orion` directories, create `orion.conf` files specifying:
|
|
|
|
|
|
* Different ports
|
|
|
* Node-1 Orion node as the bootnode (specified by [`othernodes`](http://docs.orion.pegasys.tech/en/latest/Configuring-Orion/Configuration-File/)):
|
|
|
|
|
|
```bash tab="Node-2"
|
|
|
nodeurl = "http://127.0.0.1:8081/"
|
|
|
nodeport = 8081
|
|
|
clienturl = "http://127.0.0.1:8889/"
|
|
|
clientport = 8889
|
|
|
publickeys = ["nodeKey.pub"]
|
|
|
privatekeys = ["nodeKey.key"]
|
|
|
passwords = "passwordFile"
|
|
|
othernodes = ["http://127.0.0.1:8080/"]
|
|
|
tls = "off"
|
|
|
```
|
|
|
|
|
|
```bash tab="Node-3"
|
|
|
nodeurl = "http://127.0.0.1:8082/"
|
|
|
nodeport = 8082
|
|
|
clienturl = "http://127.0.0.1:8890/"
|
|
|
clientport = 8890
|
|
|
publickeys = ["nodeKey.pub"]
|
|
|
privatekeys = ["nodeKey.key"]
|
|
|
passwords = "passwordFile"
|
|
|
othernodes = ["http://127.0.0.1:8080/"]
|
|
|
tls = "off"
|
|
|
```
|
|
|
|
|
|
## 5. Start Orion Nodes
|
|
|
|
|
|
In each `Orion` directory, start Orion specifying the [configuration file](#3-create-a-configuration-file) created in the previous step:
|
|
|
|
|
|
```
|
|
|
orion orion.conf
|
|
|
```
|
|
|
|
|
|
## 6. Start Pantheon Node-1
|
|
|
|
|
|
In the `Node-1` directory, start Pantheon Node-1:
|
|
|
|
|
|
```bash tab="MacOS"
|
|
|
pantheon --data-path=data --genesis-file=../ibftGenesis.json --rpc-http-enabled --rpc-http-api=ETH,NET,IBFT,EEA --host-whitelist=* --rpc-http-cors-origins="all" --privacy-enabled --privacy-url=http://127.0.0.1:8888 --privacy-public-key-file=Orion/nodeKey.pub --min-gas-price=0
|
|
|
```
|
|
|
|
|
|
```bash tab="Windows"
|
|
|
pantheon --data-path=data --genesis-file=..\ibftGenesis.json --rpc-http-enabled --rpc-http-api=ETH,NET,IBFT,EEA --host-whitelist=* --rpc-http-cors-origins="all" --privacy-enabled --privacy-url=http://127.0.0.1:8888 --privacy-public-key-file=Orion\nodeKey.pub --min-gas-price=0
|
|
|
```
|
|
|
|
|
|
The command line specifies privacy options:
|
|
|
|
|
|
* [`--privacy-enabled`](../Reference/Pantheon-CLI-Syntax.md#privacy-enabled) enables privacy
|
|
|
* [`--privacy-url`](../Reference/Pantheon-CLI-Syntax.md#privacy-url) specifies the Orion node URL (`clienturl` in `orion.conf`)
|
|
|
* [`--privacy-public-key-file`](../Reference/Pantheon-CLI-Syntax.md#privacy-public-key-file) specifies the file containing
|
|
|
Orion node public key (created in [3. Generate Orion Keys](#3-generate-orion-keys))
|
|
|
* [`--rpc-http-api`](../Reference/Pantheon-CLI-Syntax.md#rpc-http-api) includes `EEA` in the list of
|
|
|
JSON-RPC APIs to enable privacy JSON-RPC API methods.
|
|
|
* [`--min-gas-price`](../Reference/Pantheon-CLI-Syntax.md#min-gas-price) set to 0 for a [free gas network](../Configuring-Pantheon/FreeGas.md).
|
|
|
|
|
|
!!!note
|
|
|
The [`--data-path`](../Reference/Pantheon-CLI-Syntax.md#data-path), [`--genesis-file`](../Reference/Pantheon-CLI-Syntax.md#genesis-file),
|
|
|
and [`--privacy-public-key-file`](../Reference/Pantheon-CLI-Syntax.md#privacy-public-key-file)
|
|
|
options are not used when running Pantheon from the [Docker image](../Getting-Started/Run-Docker-Image.md).
|
|
|
|
|
|
When the node starts, the [enode URL](../Configuring-Pantheon/Node-Keys.md#enode-url) is displayed.
|
|
|
Copy the enode URL to specify Node-1 as the bootnode in the following steps.
|
|
|
|
|
|
|
|
|
|
|
|
### 7. Start Pantheon Node-2
|
|
|
|
|
|
In the `Node-2` directory, start Pantheon Node-2 specifying the Node-1 enode URL copied when starting Node-1 as the bootnode:
|
|
|
|
|
|
```bash tab="MacOS"
|
|
|
pantheon --data-path=data --genesis-file=../ibftGenesis.json --bootnodes=<Node-1 Enode URL> --p2p-port=30304 --rpc-http-enabled --rpc-http-api=ETH,NET,IBFT,EEA --host-whitelist=* --rpc-http-cors-origins="all" --rpc-http-port=8546 --privacy-enabled --privacy-url=http://127.0.0.1:8889 --privacy-public-key-file=Orion/nodeKey.pub --min-gas-price=0
|
|
|
```
|
|
|
|
|
|
```bash tab="Windows"
|
|
|
pantheon --data-path=data --genesis-file=..\ibftGenesis.json --bootnodes=<Node-1 Enode URL> --p2p-port=30304 --rpc-http-enabled --rpc-http-api=ETH,NET,IBFT,EEA --host-whitelist=* --rpc-http-cors-origins="all" --rpc-http-port=8546 --privacy-enabled --privacy-url=http://127.0.0.1:8889 --privacy-public-key-file=Orion\nodeKey.pub --min-gas-price=0
|
|
|
```
|
|
|
|
|
|
The command line specifies the same options as for Node-1 with different ports and Orion node URL. The
|
|
|
[`--bootnodes`](../Reference/Pantheon-CLI-Syntax.md#bootnodes) option specifies the enode URL for Node-1.
|
|
|
|
|
|
!!!note
|
|
|
The [`--p2p-port`](../Reference/Pantheon-CLI-Syntax.md#p2p-port) and [`--rpc-http-port`](../Reference/Pantheon-CLI-Syntax.md#rpc-http-port)
|
|
|
options are not used when running Pantheon from the [Docker image](../Getting-Started/Run-Docker-Image.md#exposing-ports).
|
|
|
|
|
|
### 8. Start Pantheon Node-3
|
|
|
|
|
|
In the `Node-3` directory and start Pantheon Node-3 specifying the Node-1 enode URL copied when starting Node-1 as the bootnode:
|
|
|
|
|
|
```bash tab="MacOS"
|
|
|
pantheon --data-path=data --genesis-file=../ibftGenesis.json --bootnodes=<Node-1 Enode URL> --p2p-port=30305 --rpc-http-enabled --rpc-http-api=ETH,NET,IBFT,EEA --host-whitelist=* --rpc-http-cors-origins="all" --rpc-http-port=8547 --privacy-enabled --privacy-url=http://127.0.0.1:8890 --privacy-public-key-file=Orion/nodeKey.pub --min-gas-price=0
|
|
|
```
|
|
|
|
|
|
```bash tab="Windows"
|
|
|
pantheon --data-path=data --genesis-file=..\ibftGenesis.json --bootnodes=<Node-1 Enode URL> --p2p-port=30305 --rpc-http-enabled --rpc-http-api=ETH,NET,IBFT,EEA --host-whitelist=* --rpc-http-cors-origins="all" --rpc-http-port=8547 --privacy-enabled --privacy-url=http://127.0.0.1:8890 --privacy-public-key-file=Orion\nodeKey.pub --min-gas-price=0
|
|
|
```
|
|
|
|
|
|
The command line specifies the same options as for Node-1 with different ports and Orion node URL. The
|
|
|
[`--bootnodes`](../Reference/Pantheon-CLI-Syntax.md#bootnodes) option specifies the enode URL for Node-1.
