Building and Running

Compiling the Blockchain

Navigate to the root directory of the project and run the following command to compile the Stability chain:

cargo build --release

Initiating the Node

To start the Stability chain in development mode, execute this command:

./target/release/stability --dev

Manual Block Sealing

For manually sealing blocks via RPC, which is particularly useful for TypeScript tests, use the following command:

./target/release/stability --dev --manual-seal

Docker Deployment

For containerized deployment options, please refer to the Docker guidelines available in the docker/ directory.

Architecture

The Stability Substrate chain is built upon Polkadot version stable-2407 and leverages the frontier framework to ensure full Ethereum compatibility. Our architecture incorporates a carefully selected set of pallets, each serving a unique role in the overall functionality of the blockchain.

Core Pallets

Consensus Mechanisms

• AuRa: An adaptive and reactive consensus algorithm for block production.
• GRANDPA: GHOST-based Recursive Ancestor Deriving Prefix Agreement for finality.
• Validator Set: Manages the dynamic validator set with automatic rotation and offline detection.

Token and Fee Management

• pallet-custom-balances: Manages native token balances with EVM compatibility.
• pallet-supported-tokens-manager: Handles supported token configurations and validations.
• pallet-user-fee-selector: Allows users to select preferred tokens for fee payment.
• pallet-validator-fee-selector: Manages validator fee token preferences.
• pallet-dnt-fee-controller: Controls decentralized native token fee mechanisms.
• pallet-fee-rewards-vault: Manages fee rewards distribution and storage.

Transaction Management

• pallet-sponsored-transactions: Enables transaction sponsorship functionality.
• pallet-zero-gas-transactions: Handles zero-gas transaction processing.
• pallet-transaction-payment: Manages transaction fee payments and calculations.

Governance and Control

• pallet-collective: Facilitates governance functionalities through collective decision-making.
• pallet-root-controller: Manages root-level administrative controls.
• pallet-upgrade-runtime-proposal: Handles runtime upgrade proposals and execution.
• pallet-validator-keys-controller: Controls validator key management and rotation.

Third-Party Pallets

• Moonbeam's precompile-utils: A utility pallet offering precompiled contract support.
• Moonbeam's RPC debug: Provides enhanced debugging capabilities and transaction pool management.
• Frontier: Provides Ethereum compatibility layer and RPC support.
