🌍 The Earth Blockchain on Polkadot (archived)


Social Network Blockchain · GitHub license PRs Welcome

The Social Network blockchain is a next-generation governance, economic, and social system for humanity built on Polkadot Substrate. To learn more read the whitepaper 🚀 🌎 .

Substrate Builders Program

Earn NET by running a Node

The Social Blockchain is powered by a decentralized backend which allows anyone in the world to participate by running the node software in this repository. This removes the need for a central party or middleman to extract rent or censor the network for personal gain, control, or power.

The network is capable of securing and maintaining a single source of truth, globally, with 6 second finality using a byzantine fault tolerant, nominated Proof-of-Stake consensus algorithm. In addition, nodes can run dedicated real time applications off-chain, and use the network consensus for discovery and access control of their services from from end social network users.

Node operators are incentivized with NET tokens for keeping the software running, and earn greater rewards the more reliable their nodes are over time. Fees generated on the chain, are distributed to Node operators proportional to how much staked NET they have on their node. Node operators can specify which Social token they wish to support, such that when NET token holders stake their tokens to a node, they will receive a bonus amount of that Social token in their wallet. These social tokens can then be used for governance or voting on global social networking applications.

Running a NET Node

To get started, you can follow the steps depending on your operating system:


Open the Terminal application and execute the following commands:

# Install Homebrew if necessary https://brew.sh/
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

# Make sure Homebrew is up-to-date, install openssl and cmake
brew update
brew install openssl cmake


Use a terminal shell to execute the following commands:

sudo apt update
# May prompt for location information
sudo apt install -y cmake pkg-config libssl-dev git build-essential clang libclang-dev curl libz-dev

Arch Linux

Run these commands from a terminal:

pacman -Syu --needed --noconfirm cmake gcc openssl-1.0 pkgconf git clang
export OPENSSL_LIB_DIR="/usr/lib/openssl-1.0"
export OPENSSL_INCLUDE_DIR="/usr/include/openssl-1.0"


Please see this guide to get setup using Windows.

Setup your Rust Environment

The Social Network software is built in rust, so Guardians must setup their tooling as follows:

Install rust with the following:

# Install
curl https://sh.rustup.rs -sSf | sh
# Configure
source ~/.cargo/env
# Configure Rust toolchain to the one needed for The Social Blockchain
rustup install nightly-2021-01-25
rustup default nightly-2021-01-25
# Install WebAssembly (WASM)
rustup target add wasm32-unknown-unknown --toolchain nightly-2021-01-25

Download The Social Blockchain

To get a copy of The Social Blockchain software on your machine:

git clone https://github.com/social-network/blockchain.git

The runtime of the blockchain is compiled down to Web Assembly (WASM) so it can be ran in embedded devices, or even the browser. To compile it run:

cd blockchain
WASM_BUILD_TOOLCHAIN=nightly-2021-01-25 cargo build --release

Note if you are doing other blockchain development work, you will need to update your toolchain to match our version for the compilation to work. Feel free to join the #support circle in the Social Technologies Society if you need help getting setup.

Help Build The Social Blockchain

As a decentralized project, we welcome all contributions that help us reach our mission faster, but ask that you follow our values. See our welcome blog for more details.

To jump right in, visit our jobs page to find a job or bounty that you think you can complete. Contributors will earn NET tokens to participate in the platform governance and help steward the decentralized technical development.


The security policy and procedures can be found in docs/SECURITY.md.


The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.

In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.

  • Rebasing v3 to master

    Rebasing v3 to master

    This PR is an attempt to rebase master against v3 so that v3 can eventually be merged into master. Since there were recent features added to both v3 and master, please pay particular attention to social-nfts and social-bridge while reviewing.

    Sorry that it's such a massive PR :(

    Ignored tests

    Due to our codebase diverging from substrate core (mainly in expectations of blockchain events and/or transaction behavior), some of the lower-level crate tests fail.

    I marked them as #[ignore] for now. See this commit for the list: https://github.com/social-network/blockchain/commit/998985be47fe68443d16ace6bb3b44167dbf026d

    This is functional but WIP because of security and further optimizations:

    • [ ] Rustfmt and whitespace
