Injective Publishing Node

This repository is a fork of InjectiveLabs/injective-core, specifically enhanced to include functionality for NATS publishing. It allows the injectived node to publish data streams of transactions, mempool, blocks, and proposed blocks.

Added Functionality

• NATS Publishing: Enhances the injectived node to publish details about transactions, mempool, blocks, and proposed blocks via NATS. This feature enables subscribers to receive real-time blockchain data.

• How to Use: To enable the publishing features, you must set the following environment variables before starting the injectived node. These variables configure the NATS connection and define the publishing settings:

  • NATS URL
    NATS_URL=your-nats-url

  • NATS NKey
    NATS_NKEY=your-nats-nkey

  • NATS JWT
    NATS_JWT=your-nats-jwt

  • Publisher Prefix
    PUB_PREFIX=your-publisher-prefix

  • Publisher Name
    PUB_NAME=your-publisher-name

  You can use these environment variables in the injectived or cosmovisor service file. For example:

  [Unit]
  Description=Injectived Service
  After=network.target
  
  [Service]
  User=injective
  Type=simple
  Restart=on-failure
  RestartSec=5s
  Environment="NATS_URL=your-nats-url"
  Environment="NATS_NKEY=your-nats-nkey"
  Environment="NATS_JWT=your-nats-jwt"
  Environment="PUB_PREFIX=your-publisher-prefix"
  Environment="PUB_NAME=your-publisher-name"
  Environment="LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/"
  Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin:/home/injective/go/bin"
  ExecStart=/home/injective/injectived start
  
  [Install]
  WantedBy=multi-user.target
  

To improve node performance and save space, configure the following settings in your app.toml and config.toml files:

app.toml:

# Prune Type
pruning = "custom"

# Prune Strategy
pruning-keep-recent = "100"
pruning-keep-every = "0"
pruning-interval = "10"

config.toml:

indexer = "null"
peer_gossip_sleep_duration = "2ms"
persistent_peers = "" # load all peers from https://polkachu.com/live_peers/injective
max_num_outbound_peers = 100

Architecture

Installation

Building from sources

In order to build from source you’ll need at least Go 1.16+.

# need to clone if you plan to run tests, and use Makefile
$ git clone git@github.com:InjectiveLabs/injective-core.git
$ cd injective-core
$ make install

# or simply do this to fetch modules and build executables
$ go install github.com/InjectiveLabs/injective-core/cmd/...

Quick Setup

The most convenient way to launch services is by running the setup script:

$ ./setup.sh

Then run an instance of the injectived node.

$ ./injectived.sh

Voila! You have now successfully setup a full node on the Injective Chain.

Generating the module specification docs

$ cd docs && yarn && yarn run serve

Generating REST and gRPC Gateway docs

First, ensure that the Enable and Swagger values are true in APIConfig set in cmd/injectived/config/config.go.

Then simply run the following command to auto-generate the Swagger UI docs.

$ make proto-swagger-gen

Then when you start the Injective Daemon, simply navigate to http://localhost:10337/swagger/.

Generating Injective Chain API gRPC Typescript bindings

$ make gen

Then when you start the Injective Daemon, simply navigate to http://localhost:10337/swagger/.

Maintenance

To run all unit tests:

$ go test ./injective-chain/...
