GRAVITY

Deterministic Bitcoin Infrastructure

I. Definition

Gravity is a deterministic infrastructure layer operating within Bitcoin’s settlement domain.

It provides two bounded services:

• Relay
• Certification

Both activate exclusively through confirmed on-chain settlement.

II. Activation Model

Service activation follows a single deterministic sequence:

1. Invoice generation
2. Settlement to designated address
3. Required confirmation depth
4. Entitlement state transition

Upon confirmation, service state becomes ACTIVE.

State transitions are binary and machine-evaluated.

III. Entitlement Model

Access is capability-bound.

Invoice ID functions as the entitlement reference.

Entitlement state transitions follow a fixed progression:

UNPAID → ACTIVE → EXPIRED

Execution is permitted only while state is ACTIVE.

Entitlement scope is finite and confirmation-derived.

IV. Relay

Relay provides controlled event ingestion and persistence within an ACTIVE entitlement window.

Events submitted to the relay endpoint are:

• Schema validated
• Entitlement verified
• Persisted deterministically
• Acknowledged with structured response

Relay execution remains strictly bound to settlement-derived entitlement scope.

V. Certification

Certification issues deterministic attestations bound to settlement-derived entitlement.

Upon ACTIVE state:

• Certification logic executes
• A machine-readable JSON artifact is produced
• Issuance timestamp is recorded
• Artifact becomes queryable

Certification output reflects executed state at time of issuance.

VI. Determinism

• Identical settlement activation logic
• Explicit confirmation thresholds
• Immutable state transitions
• Versioned operational behavior

Activation and issuance states are verifiable through defined interfaces.

VII. Infrastructure Posture

Gravity enforces activation and execution strictly through Bitcoin confirmation depth.

Behavior is deterministic.
Outputs are verifiable.
Entitlement remains bounded to confirmed settlement.
