Nodecore

Nodecore is a self-hosted, API-agnostic proxy and load balancer for blockchain RPC services. It routes requests among configured providers using performance signals and offers controls including caching, retries, hedging, rate limiting and quorum verification.

Practical overview

When it fits

Use Nodecore when you operate a blockchain application and want a self-hosted layer between the application and one or more RPC providers, with routing and request-management policies configured centrally.

Who it is for

  • Teams operating blockchain applications that need to route RPC traffic across multiple providers.
  • Infrastructure engineers seeking a configurable gateway for blockchain APIs and operational monitoring.

Documented uses

  • Distribute blockchain API requests across configured RPC providers.
  • Select upstreams using performance measures such as latency, throughput and error rates.
  • Apply caching, retries, hedged requests and rate limits to upstream traffic.
  • Compare independently signed upstream responses through quorum verification.
Before you choose

Requirements & limits

The project is available as a public MIT-licensed GitHub repository. The README documents Docker and source-build approaches.

  • Provider endpoints and a configuration file are required for the documented Docker setup.
  • Supported interfaces and methods vary by chain specification; check the chain's method spec before relying on a particular RPC shape or method.
  • The README describes the project as under active development.
  • The repository documents Docker deployment and a source build using make build and make run.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Configure and start Nodecore with Docker

Start the gateway using a YAML configuration with at least one blockchain RPC upstream.

Before you start

  • Docker
  • A Nodecore YAML configuration file
  • At least one blockchain RPC provider URL and its chain and connector details

Steps

  1. Create a configuration with an upstream entry specifying its ID, chain, connector type and provider URL.

  2. Run the documented Docker image, publish port 9090 and mount the configuration at /nodecore.yml.

  3. Send a JSON-RPC request to the local /queries/{chain} route, following the Ethereum example in the README.

Expected outcome

A locally running Nodecore gateway configured with an upstream, ready to receive a request in the documented format.

Guide limitations

  • The example request uses Ethereum and JSON-RPC; available methods and interfaces depend on the chain's method specification.
  • The project is described as under active development.

Build and run Nodecore from source

Build the repository binary and start it with a local configuration.

Before you start

  • A Go development environment with the repository's build tooling
  • A cloned Nodecore repository
  • A Nodecore configuration file

Steps

  1. Clone the repository from its GitHub URL.

  2. Run the command below; the documented build command runs the command below automatically.

    Documented command
    make build
    Documented command
    make generate-networks

  3. Run the command below to use ./nodecore.yml by default, or set NODECORE_CONFIG_PATH to specify another configuration path.

    Documented command
    make run

Expected outcome

A locally built Nodecore binary started with the selected configuration.

Guide limitations

  • The README notes that make run does not regenerate chain data; run make generate-networks first if needed.
  • The project is described as under active development.
