GLOSSARY

The language behind the substrate.

A practical reference for the concepts you’ll meet in the website and control panel.

STATE

Append-only sync

Representing state evolution as an ordered sequence of changes rather than silently replacing its history.

DELIVERY

Baseline

A complete response or state held by a participant. A delta can be applied only to a compatible baseline.

IDENTITY

Client identity

A client identifier bound to a public key and, after authentication, an account for a particular origin.

DELIVERY

Delta

The changes required to move a known baseline to a newer state. A no-change response means that baseline remains current.

STATE

Deterministic transition

A transition with a defined result for the same valid starting state and inputs.

INFRASTRUCTURE

Domain

A logical cluster grouping nodes and origins within an account. It is distinct from an individual origin hostname.

IDENTITY

Ed25519

The public-key signature scheme used to sign protected requests. The server verifies each signature against the bound public key.

PROTOCOLS

ETCP

A transport and coordination component in the Spook Systems protocol family.

PROTOCOLS

ESTP

The state-transfer component of the protocol family.

INFRASTRUCTURE

Fallback

A node assigned to the Fallback role for a domain, used alongside its Master in the configured recovery arrangement.

IDENTITY

Identity gate

The ingress boundary that verifies authenticated client identity and request signatures before forwarding protected requests.

INFRASTRUCTURE

Master

The node assigned the Master role in a domain. Membership and the corresponding Fallback role are configured in Infrastructure.

INFRASTRUCTURE

Node

A licensed QSCS daemon instance participating in one or more configured domains.

INFRASTRUCTURE

Origin

A hostname served through QSCS, with its own backend address, cache policy and identity settings.

PROTOCOLS

QCCP

The orchestration interface for coordinating classical control state and configured compute backends.

PROTOCOLS

QN

The Quantum Network component in the protocol family, coordinating distributed participants and state propagation.

PROTOCOLS

QSCS

The shared foundation for deterministic coordination and state delivery.

MONITORING

SpookVis

The control-panel views for account-scoped traffic, nodes, latency, cache behaviour and other available telemetry.

IDENTITY

Trust boundary

A point where identity, permissions and data provenance are checked before a request or state change can cross into another system.

DELIVERY

WASM

WebAssembly. The browser runtime used by the QSCS web integration for cryptographic identity and state reconstruction.

DETERMINISTIC BY CONSTRUCTION

Build On A State-First Foundation.

Explore how deterministic shared state can simplify coordination, recovery, and communication across the systems you already run.
