BlessChain is a Substrate-based development blockchain focused on structural simplicity, fixed supply design, zero inflation, and long-term infrastructure stability.
BlessChain is currently in the Development Network phase.
- Runtime compiles successfully
- Real Substrate node service is connected
- Manual-seal development consensus is running
- RPC server available at
ws://127.0.0.1:9944 - Polkadot.js connectivity confirmed
- Blocks are produced, imported, and finalized in local dev mode
The previous mock block loop has been replaced by a real Substrate service using:
sc_service- transaction pool
- network service
- RPC service
- manual-seal block production
Development Network / Devnet
Multi-validator local testnet, then staged public testnet.
BlessChain is not yet mainnet.
The current network is for development, testing, and infrastructure validation only.
The Polkadot SDK repository provides all the components needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way.
If you want to get an example node running quickly you can execute the following getting started script:
curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/paritytech/polkadot-sdk/master/scripts/getting-started.sh | bash
In order to build this project you need to install some dependencies, follow the instructions in this guide.
- Polkadot Documentation Portal
- 🦀 rust-docs: Where we keep track of
the API docs of our Rust crates. Includes:
- Introduction to each component of the Polkadot SDK: Substrate, FRAME, Cumulus, and XCM
- Guides, namely how to build your first FRAME pallet
- Templates for starting a new project.
- External Resources
- Have a question? You can ask in the Polkadot SDK Developers Chat. Messages from either of these channels are bridged to the other, so you can use whichever one you like.
The Polkadot SDK is released every three months as a Polkadot stableYYMM release. Each stable release is supported for
one year with patches. See the next upcoming versions in the Release
Registry and more docs in RELEASE.md.
You can use psvm to update all dependencies to a specific
version without needing to manually select the correct version for each crate.
Polkadot SDK Version Manager: A simple tool to manage and update the Polkadot SDK dependencies in any Cargo.toml file. It will automatically update the Polkadot SDK dependencies to their correct crates.io version.
The security policy and procedures can be found in docs/contributor/SECURITY.md.

We always recognize valuable contributions by proposing an on-chain tip to the Polkadot network as a token of our
appreciation.
Development in this repo usually goes hand in hand with the fellowship organization. In short,
this repository provides all the SDK pieces needed to build both Polkadot and its parachains. But,
the actual Polkadot runtime lives in the fellowship/runtimes repository. Read more about the
fellowship, this separation, the RFC process
here.
This repository is the amalgamation of 3 separate repositories that used to make up Polkadot SDK, namely Substrate, Polkadot and Cumulus. Read more about the merge and its history here.
