Arctanz

Arctanz is a fictional open standard described in speculative-technology literature for encoding, transmitting, and synchronizing time-series data across distributed sensor networks. In the imagined ecosystem, arctanz defines a layered protocol stack that separates data modeling, transport, and encoding, with an emphasis on deterministic ordering and fault tolerance in unreliable networks. The name combines hints of arc-based routing and tangent-like influence among streams.

Data model: Each record carries a unique identifier, a monotonically increasing timestamp, a value, and optional metadata. Records are designed to be immutable and content-addressed, enabling efficient deduplication and integrity checks via cryptographic hashes. The model supports optional causality metadata to enable retrospective queries.

Encoding and transport: Arctanz specifies a compact binary encoding called ArcBin, optimized for low bandwidth. Transport uses a hybrid gossip protocol with selective retransmission and a light consensus mechanism to maintain a global order of events. It also provides hooks for end-to-end encryption and access control.

History and status: The concept of arctanz emerged in collaborative worldbuilding projects in the 2010s and has since appeared in several academic exercises analyzing data synchronization in distributed systems. It is not a real-world standard, but it is cited in discussions about trade-offs in time-sensitive data delivery.

Applications and reception: In the fictional universe, arctanz is used for industrial telemetry, environmental monitoring, and cross-site simulations. Real-world analogues to its ideas include time-series databases, streaming protocols, and CRDT-based synchronization.
