Objects
The record that carries meaning, authority, and transfer semantics.
Core Model
Three primitives, three operations, one portable record layer.
Controllers
The keys or actors able to exercise exclusive control over the record.
Events
The signed actions that express transfer, endorsement, and enforcement.
Canonical View
The canonical model makes the scheme legible at a glance.
This diagram shows the basic OpenETR vocabulary in one frame: an object is the record surface, a controller is the party able to exercise control, and events are the signed transitions that move authority over time.
It is useful as both a conceptual map and an implementation guide, because it keeps the scheme focused on portable control rather than on any one platform, registry, or application boundary.
Why It Matters
Built for records that must outlive platforms and move with confidence.
Durable
Records persist independently of any single vendor, registry, or institution.
Portable
Control can move without re-issuance, lock-in, or proprietary dependencies.
Verifiable
Proofs are machine-checkable and can be validated outside the originating system.
First Reference Implementation
Nostr is the first protocol foundation for the OpenETR scheme.
Signed Events
Nostr already models portable, signed event data, which makes it a natural starting point for expressing records, controllers, and transfer actions.
Relay Distribution
Events can move across independent relays instead of being trapped inside a single registry, platform, or institution.
Independent Verification
OpenETR builds on Nostr's verification model to show how durable control and portable records can work on open infrastructure today.
Underlying Philosophy
Transact globally, validate locally.
OpenETR is designed for an open, permissionless environment: events can circulate globally, while validation, attestation, and recognition remain with the party that must decide whether to rely on the resulting chain.
Global Publication
OpenETR does not assume a single controlling platform or registry. It aims to let control-relevant events move through shared infrastructure while remaining signed, attributable, and reviewable.
Local Recognition
The protocol provides evidence. It does not by itself determine final legal or operational effect. That remains a matter for the assessor, attestor, or relying party applying the relevant policy.
Sound Cryptographic Basis
The goal is not to prevent every possible action at the protocol layer, but to create a sound cryptographic basis on which recognition decisions can later be made.
Historical Context
Inspired by the operating ethos of maritime trade on the high seas.
Trade Across Boundaries
Global shipping developed across ports, carriers, merchants, financiers, and legal systems long before any single sovereign could govern trade end to end.
Records That Travel
Maritime commerce depended on documents, customs, and recognition practices that could move across jurisdictions. Bills of lading mattered because they were portable records of control, not because they belonged to one system.
Digital Parallel
OpenETR is an attempt to replicate some of that ethos digitally: publication in a shared environment, movement across institutional boundaries, and recognition based on reliable evidence rather than centralized platform control.
Digital Trade Context
MLETR helps make digital trade documents legally usable across borders.
What It Is
The UNCITRAL Model Law on Electronic Transferable Records, or MLETR, provides a legal framework for electronic records to function like transferable paper instruments.
Why It Matters
For trade documents such as bills of lading, warehouse receipts, and promissory notes, MLETR creates a path for digital records to carry possession-like control and legal effect.
Why OpenETR Fits
OpenETR focuses on durable control, transfer, and independent verification, which are exactly the technical qualities needed to support MLETR-aligned digital trade documentation.
Early Uses
Starting points for open, transferable digital instruments.
Under MLETR-style legal frameworks, electronic bills of lading are one of the clearest examples of why durable digital control matters.
