Subspace

Subspace is a FRAME-based Substrate blockchain node that provides the foundation for Commune's network. It serves as the trusted base layer responsible for consensus, module advertising, and peer discovery.

Overview

Subspace is built using Substrate, a framework for developing scalable and upgradeable blockchains. It provides the core functionality and security needed for Commune's platform:

1. Implements Commune's consensus mechanism
2. Advertises cluster modules and their IP addresses
3. Enables peer discovery for nodes to connect with each other

System Requirements

• Supported OSs: Linux, MacOS
• Supported Architectures: x86_64
• Memory: ~ 286MB
• Disk: ~500MB
• Network: Public IPv4 address, TCP ports 9944, 30333 open

Installation

1. Complete the basic Rust setup instructions.

2. Clone this repository:

git clone https://github.com/commune-network/subspace.git
cd subspace/

Usage

Build

To build the node without launching it, run:

cargo build --release

Run

To run a single development node with ephemeral storage:

./target/release/node-subspace --chain specs/local.json

This will start a Subspace node with a clean state. The node's state will be discarded on exit.

To retain the node's state between runs, specify a base path:

mkdir my-chain-state/
./target/release/node-subspace --dev --base-path ./my-chain-state/  

Other useful commands:

# Purge chain state
./target/release/node-subspace purge-chain --dev

# Detailed logging
RUST_BACKTRACE=1 ./target/release/subspace-ldebug --dev

# Explore parameters and subcommands 
./target/release/node-subspace -h

Test

To run all tests:

cargo test --all

To run specific tests:

cargo test -p pallet-subspace --test test_voting

To run tests with detailed logs:

SKIP_WASM_BUILD=1 RUST_LOG=runtime=debug cargo test -- --nocapture  

Architecture

Subspace leverages the modular and extensible architecture of Substrate. It uses FRAME pallets to encapsulate domain-specific logic such as consensus, storage, and p2p networking.

Notable components:

• /node: Implementation of the Subspace node including networking, consensus, and RPC
• /runtime: The core blockchain logic responsible for validating and executing state transitions
• /pallets: Custom FRAME pallets with Commune-specific logic
