Core

The jam.core module implements the fundamental components of the JAM protocol, providing the foundation for the Tessera node.

Core Components

The core module consists of several key components:

Block Processing

The block processing system handles the validation and application of blocks:

• Block Validation: Verify block format, signatures, and state transitions
• Block Import: Import new blocks into the chain
• Block Application: Apply block state transitions
• Fork Choice: Determine the canonical chain

Extrinsic Processing

The extrinsic processing system manages the handling of transactions:

• Extrinsic Validation: Verify transaction format and signatures
• Extrinsic Storage: Store extrinsics temporarily
• Extrinsic Application: Apply transaction state transitions
• Extrinsic Ordering: Order transactions within a block

State Transition Functions

The core module implements the state transition functions defined in the JAM protocol:

• α: Authorization pool
• β: Block history
• γ: Safrole consensus state
• δ: Service accounts
• η: Entropy accumulator
• ι: Validator key queue
• κ: Active validator keys
• λ: Previous epoch validator keys
• ρ: Work reports queue
• τ: Current timeslot
• φ: Authorization queue
• χ: Privileged services
• ψ: Work report judgments
• π: Validator statistics
• ν: Accumulation queue
• ξ: Work report history
