The Thru Runtime is the execution environment that processes transactions on the Thru blockchain. It manages the complete transaction lifecycle from validation through execution to state commitment.

​
Key Components

​
Transaction Execution

Covers the multi-phase transaction processing pipeline including pre-execution validation, VM execution, and post-execution rules.

​
Resource Management

Defines the resource metering system with Compute Units (CUs) for instruction execution, Memory Units (MUs) for scratch space allocation, and resource consumption patterns.

​
Error Handling

Comprehensive error codes organized by transaction lifecycle stage, from validation errors to execution failures and system-level issues.
