Substrate
Substrate is a modular blockchain development framework used to build customized blockchain networks with programmable state transitions and consensus mechanisms. It functions as a toolkit for constructing bespoke network protocols and deploying nodes to local environments or global testnets.
The framework utilizes a WebAssembly runtime environment to execute state transition logic, ensuring deterministic behavior across all network nodes. It enables the composition of modular logic components and runtime palettes to define the specific rules and behavior of a blockchain.
The system covers core blockchain operations including signed transaction processing, block authoring management, and the integration of environmental data. It also provides cryptographic key administration for secure session key storage and rotation, as well as tools for isolated binary compilation and node orchestration.
