Mathematical Foundations of Opaque State Infrastructure
Mathematical Foundations of Opaque State Infrastructure Formal Model and Comparative Analysis of the Cryptographic Lockbox Transaction Substrate Part I: Formal Model (Abstract, Non-Operational) I.1 Entities and Sets L — Set of lockboxes S — Set of stimuli (broadcast inputs) C — Set of commitments W — Set of witnesses (bounded proofs) N — Set of substrate nodes T — Totally ordered event index (time/order) I.2 Lockbox Definition A lockbox ℓ ∈ L is a deterministic state machine: ℓ := (x, δ, R, K, κ) Where: x — private internal state δ — deterministic transition function R — set of receptor predicates K — internal key material κ — commitment function mapping state to C Properties: x is never externally observable δ is total and deterministic R is private and non-discoverable κ(x) binds future transitions I.3 Stimulus Model A stimulus s ∈ S is a uniform broadcast object with no addressability. Each lockbox evaluates:...
