Method — On-Chain Validation
Definition, scope boundary, and structural model.
Definition
On-chain validation is a structural method for verifying transactions and state transitions within a blockchain or distributed ledger system.
Verification is executed through protocol-defined rules and consensus mechanisms that determine whether a given state transition is accepted as part of the ledger.
Scope Boundary
Included
Protocol-level transaction validation
Consensus-based state verification
Block validation and acceptance rules
Smart contract execution validation
Cryptographic proof verification within the ledger
Excluded
Off-chain validation processes
External data verification systems (oracles)
Non-protocol validation logic
Regulatory or legal validation frameworks
Operational deployment or node configuration
Structural Phase Model
Phase 1 — Submission
A transaction or state transition is submitted to the network for validation.
Phase 2 — Rule Evaluation
Protocol rules are applied to determine whether the submitted data satisfies validation conditions.
Phase 3 — Consensus Determination
Validation results are determined through the consensus mechanism governing the network.
Phase 4 — State Inclusion
Validated state transitions are incorporated into the ledger as part of an accepted block.
