NineChronicles.Headless
NineChronicles.Headless copied to clipboard
A headless node of NineChronicles game network, powered by Libplanet.
NineChronicles Headless
Run
If you want to run node to interact with mainnet, you can run the below command line:
dotnet run --project NineChronicles.Headless.Executable -C appsettings.mainnet.json --store-path={PATH_TO_STORE}
For more information on the command line options, refer to the CLI Documentation.
Use appsettings.{network}.json
to provide CLI options
You can provide headless CLI options using file, appsettings.json
. You'll find the default file at here.
The path of appsettings.json
can be either local file storage or URL.
Refer full configuration fields from this file, set your options into appsettings.json
under Headless
section.
You can also run headless server with previous way; You don't need to change anything if you don't want to.
In case that the same option is provided from both appsetting.json
and CLI option, the CLI option value is used instead from appsettings.json
.
The default appsettings.json
is an example for your own appsettings file.
appsettings.{network}.json
are runnable appsettings file and you can run local node for each network using following command:
dotnet run --project NineChronicles.Headless.Executable -C appsettings.{network}.json --store-type={YOUR_OWN_STORE_PATH}
- appsettings.mainnet.json
- This makes your node to connect to the Nine Chronicles mainnet (production).
- appsettings.internal.json
- This makes your node to connect to the Nine Chronicles internal network, which is test before release new version.
- Internal network is kind of hard-fork of mainnet at some point to test new version.
- You CANNOT use mainnet storage for internal headless node.
- appsettings.previewnet.json
- This makes your node to connect to the Nine Chronicles preview network to show feature preview.
- This network is totally different network from genesis block.
- Previewnet can be restarted from genesis block without any announcement to prepare next feature.
Please make sure the store in the path you provided must save right data for the network to connect. You cannot share data from any of those networks.
If you want to run your own isolated local network, please copy appsettings.json
to appsettings.local.json
and edit the contents.
cp appsettings.json appsettings.local.json
# Edit contents of appsettings.local.json
dotnet run --project NineChronicles.Headless.Executable -C appsettings.local.json --store-type={YOUR_OWN_STORE_PATH}
Caveat
APVs can be changed as Nine Chronicles deploys new version. You have to fit your APV sting to current on-chain version string. You can get APV strings at the following places:
- mainnet: Official released config.json -
AppProtocolVersion
- internal: Internal network config -
APP_PROTOCOL_VERSION
- previewnet: Previewnet config -
APP_PROTOCOL_VERSION
Docker Build
A headless image can be created by running the command below in the directory where the solution is located.
$ docker build . -t <IMAGE_TAG> --build-arg COMMIT=<VERSION_SUFFIX>
- Nine Chronicles Team uses
<VERSION_SUFFIX>
to build an image with the latest git commit and push to the official Docker Hub repository. However, if you want to build and push to your own Docker Hub account, the<VERSION_SUFFIX>
can be any value.
Format
Formatting for PrivateKey
or Peer
follows the format in [Nekoyume Project README][../README.md].
How to run NineChronicles Headless on AWS EC2 instance using Docker
On Your AWS EC2 Instance
Pre-requisites
- Docker environment: Docker Installation Guide
- AWS EC2 instance: AWS EC2 Guide
1. Pull planetariumhq/ninechronicles-headless
Docker image to your AWS EC2 instance from the official Docker Hub repository.
- If you would like to build your own Docker image from your local machine, refer to this section.
$ docker pull planetariumhq/ninechronicles-headless:[<TAGNAME>] (ex: v100300)
- Please refer to the
docker
value in https://release.nine-chronicles.com/apv.json for the latest official Docker tag name. - Docker Pull Guide
2. Create a Docker volume for blockchain data persistence
$ docker volume create [<VOLUME_NAME>] (ex: 9c-volume)
3. Run your Docker image with your Docker volume mounted (use -d for detached mode)
$ docker run \ --detach \ --volume 9c-volume:/app/data \ planetariumhq/ninechronicles-headless:[] \ [NineChronicles Headless Options]
Note)
-
If you want to use the same headless options as your Nine Chronicles game client, please refer to the
headlessArgs
values in value in https://release.nine-chronicles.com/apv.json. -
If you are using an Elastic IP on your AWS instance, you can add the IP address in the
--host
option and not use the--ice-server
option. -
For mining, make sure to include the
--miner-private-key
option with your private key.
Building Your Own Docker Image from Your Local Machine
Pre-requisites
- Docker environment: Docker Installation Guide
- Docker Hub account: Docker Hub Guide
1. Build Docker image with the tag name in [<DOCKER_HUB_ACCOUNT>/<IMAGE_NAME>]
format.
$ docker build . --tag [<DOCKER_HUB_ACCOUNT>/<IMAGE_NAME>]:[<TAGNAME>] --build-arg COMMIT=[<VERSION_SUFFIX>]
2. Push your Docker image to your Docker Hub account.
$ docker push [<DOCKER_HUB_ACCOUNT>/<IMAGE_NAME>]:[<TAGNAME>]

Create a new genesis block
1. Create config file for genesis block
- Copy
config.json.example
toconfig.json
- Change values inside
config.json
-
data.tablePath
is required. - If you have
PendingActivation
file, set file path toextra.pendingActivationStatePath
-
Structure of genesis block
Key | Type | Required | Description |
---|---|---|---|
data | Required | Related to the game data. This field is required. | |
data.tablePath | string | Path of game data table. Lib9c/Lib9c/TableCSV for NineChronicles. |
|
currency | Optional | Related to currency data. Set initial mint / deposits. | |
currency.initialMinter | PrivateKey (string) | PrivateKey of initial minter. Initial minting Tx. will be signed using this key and included in genesis block. |
|
currency.initialCurrencyDeposit | List | Initial deposit data. These data will be created to Tx. and goes inside of genesis block. If you leave this to null, the initialMinter will get 10000 currency as default. |
|
currency.initialCurrencyDeposit[i].address | Address (string) | Address of depositor. Use address string except leading 0x . |
|
currency.initialCurrencyDeposit[i].amount | BigInteger | Amount of currency give to depositor. This amount will be given every block from start to end. ex) 100 from 0 to 9: total 1000 currency will be given. |
|
currency.initialCurrencyDeposit[i].start | long | First block to give currency to depositor. genesis block is #0 | |
currency.initialCurrencyDeposit[i].end | long | Last block to give currency to depositor. If you want to give only once, set this value as same as start . |
|
currency.allowMint | boolean | Allow/Disallow additional mint or burn against the initial currency. | |
admin | Optional | Related to admin setting. | |
admin.activate | bool | If true, give admin privilege to admin address. | |
admin.address | Address (string) | Address to be admin. If not provided, the initialMinter will be set as admin. |
|
admin.validUntil | long | Block number of admin lifetime. Admin address loses its privilege after this block. | |
initialValidatorSet | Optional | Initial Validator set for this blockchain. Do not provide this section if you want to use default setting. | |
initialValidatorSet[i].publicKey | PublicKey (string) | Public Key of validator. | |
initialValidatorSet[i].power | long | Voting power of validator. Min. value of voting power is 1. | |
initialMeadConfigs | Optional | Initial MEAD distributions | |
initialMeadConfigs[i].address | Address (string) | Recipient address | |
initialMeadConfigs[i].amount | BigInteger | Amount of initial MEAD | |
initialPledgeConfigs | Optional | Initial pledges introduced from NCIP-15 | |

initialPledgeConfigs[i].patronAddress | Address (string) | Address of patron who will fund | |
initialPledgeConfigs[i].mead | int | Amount of MEAD that will be funded per each blocks |
2. Create genesis block
dotnet run --project ./NineChronicles.Headless.Executable/ genesis ./config.json
After this step, you will get genesis-block
file as output and another info in addition.
3. Run Headless node with genesis block
dotnet run --project ./NineChronicles.Headless.Executable/ \
-V=[APP PROTOCOL VERSION] \
-G=[PATH/TO/GENESIS/BLOCK] \
--store-type=memory \
--store-path= [PATH/TO/BLOCK/STORAGE] \
--host=localhost \
--port=43210 \
--miner-private-key=[PRIVATE_KEY_OF_BLOCK_MINER]
