Horae, Arianee, Aura Blockchain Consortium: three approaches to the digital product passport in luxury
When a luxury maison starts looking into the digital product passport, three names quickly keep coming up: Arianee, Aura Blockchain Consortium and Horae. They are often presented as direct competitors. That is a misreading. All three operate in the same space, but they address different problems, with different philosophies. Here is a factual reading to help understand what each one really solves.
The initial misunderstanding
The term Digital Product Passport (DPP) covers very different realities. For some players, it is first and foremost a tamper-proof certificate of authenticity. For others, it is supply chain traceability infrastructure. For others still, it is a relationship channel between the brand and the product’s owner. These three definitions are not mutually exclusive, but they do not carry the same priority, and that is precisely what sets Arianee, Aura and Horae apart.
Before comparing, then, you need to ask the right question. It is not which is the best DPP platform. It is: which problem am I trying to solve first. The answer naturally points towards one of the three approaches.
Arianee: the open protocol, focused on ownership
Arianee is a protocol built around blockchain and the notion of digital ownership. Its founding logic: each product receives a digital passport that belongs to the owner, not the brand, and that can be transferred like an asset on resale. Arianee chose open source and a decentralised approach, with a protocol that several players can use.
This philosophy has a clear strength: the portability of the passport and the robustness of proof of ownership on the secondary market. If your priority is to give the owner a digital certificate they genuinely control, transferable and verifiable in a decentralised way, that is Arianee’s angle.
The flip side of this philosophy: the brand adopts a model in which it is not at the centre of the data. Decentralisation is a principle, not a technical detail. For a maison that above all wants to consolidate its customer knowledge in its own systems, this model calls for careful thought about data governance.
Aura Blockchain Consortium: industry infrastructure, focused on traceability
Aura Blockchain Consortium was born of a different logic: that of infrastructure shared between major groups. Founded in 2021 at the initiative of LVMH, Prada Group and Cartier (Richemont group), later joined by other players, Aura is a consortium. You do not buy Aura like software; you join a common infrastructure.
Aura’s priority is traceability and authenticity at industry scale: proving a product’s origin, journey and authenticity on a blockchain shared and governed by its members. For a very large group that wants a common layer of trust across several maisons, pooled and collectively governed, it is a coherent answer.
The consortium model implies two things. First, a logic of membership and collective governance, better suited to large groups than to independent or mid-sized maisons. Second, a priority given to product traceability, where the owner relationship and commercial management are adjacent topics rather than the core of the system.
Horae: the owner intelligence layer, focused on the relationship and sell-out
Horae starts from an operational observation: most luxury maisons do not know who actually owns their products. Between wholesale distribution, multi-brand retailers, gifting and the second-hand market, the end owner remains invisible in most cases. Horae focuses on this precise problem: identifying the owner at every stage of the product’s life, and reconnecting that data to the brand’s systems.
In practice, Horae works as an owner intelligence layer that integrates with the maison’s existing tools (CRM, ERP, e-commerce) rather than replacing them. The digital passport, accessible via QR code or NFC, is the point of contact. What happens behind it is the real value: identification of successive owners, tracking of actual sell-out through retailers, and activation of the post-purchase relationship.
- Identification of the end owner, including on wholesale sales and the second-hand market
- Tracking of actual sell-out: who buys, where, when, through which channel, in near real time
- Post-purchase engagement: services, content, invitations, linked to the right owner
- Fully white-label platform: the experience remains the maison’s own
- Native integrations with existing CRM, ERP and e-commerce platforms
The data remains the brand’s, in the brand’s systems. Horae does not require joining a consortium or adopting a decentralised logic. It is a deliberate positioning choice: the priority is customer knowledge and commercial management, not supply chain traceability or the certificate alone.
The right question is not which platform is best, but which problem I solve first: traceability, proof of ownership, or knowing my owners.
A factual comparison
The table below summarises the structural differences. The aim is not to rank, but to clarify the philosophies. Each player is consistent with its founding logic.
| Dimension | Arianee | Aura Blockchain Consortium | Horae |
|---|---|---|---|
| Founding logic | Open blockchain protocol, digital ownership | Industry consortium, shared infrastructure | Owner intelligence layer |
| Top priority | Transferable proof of ownership | Product traceability and authenticity | Owner identification and actual sell-out |
| Access model | Open-source protocol | Consortium membership | White-label SaaS platform |
| Natural target | Brands comfortable with a decentralised logic | Large multi-maison groups | Independent maisons, mid-sized to large |
| Data governance | Decentralised, owner-centric | Collective, governed by members | Centralised with the brand, in its own systems |
| Actual sell-out tracking | Not positioned on this topic | Not positioned on this topic | Core of the offering |
| Post-purchase engagement | Possible via the passport | Adjacent topic | Core of the offering |
| Integration with existing tools | Via the protocol | Via the consortium infrastructure | Native: CRM, ERP, e-commerce |
| White-label | Depends on implementation | Depends on implementation | Complete by default |
This table reflects each player’s public positioning at the time of writing. All three platforms are evolving their offering. For a purchasing decision, direct consultation remains essential.
Which player for which problem
If your priority is transferable proof of ownership. You want the owner to hold a digital certificate they control, verifiably transferable on resale, on a decentralised basis. This is Arianee’s historical angle. The question to ask: is your maison comfortable with a model in which it is not at the centre of owner data.
If your priority is traceability at group level. You are a large group and want a common layer of trust across several maisons, pooled and collectively governed, centred on product origin and authenticity. Aura Blockchain Consortium fits this need. The question to ask: does the logic of membership and collective governance suit your organisation.
If your priority is knowing who owns your products and managing your sell-out. You find that you know only a fraction of your owners by name, that your actual sell-out reaches you weeks late, and that the second-hand market escapes you. Your goal is to reconnect owner data to your systems and activate the post-purchase relationship. This is the problem Horae has chosen to solve first.
The three approaches can coexist
An often overlooked point: these three philosophies are not mutually exclusive. A maison can rely on traceability at group level while deploying an owner intelligence layer at maison level. Proof of ownership, traceability and customer knowledge are three real needs. They are simply not served by the same building block.
What matters is clarity about the priority. A maison that chooses a traceability platform thinking it will solve its customer knowledge problem will be disappointed, and vice versa. The disappointment does not stem from the quality of the tool, but from a mismatch between problem and solution.
How to decide
Three questions, in this order, are enough to clarify the decision:
- Which problem do I want to solve first: proof of ownership, product traceability, or knowledge of my owners and my sell-out
- Which data governance is compatible with my organisation: decentralised, collective within a consortium, or centralised in my own systems
- What level of integration with my existing tools (CRM, ERP, e-commerce) do I need for the project to be genuinely operational
If the answer to the first question is knowing who owns my products and managing my actual sell-out, then the conversation is worth pursuing with Horae. If it is decentralised proof of ownership, Arianee is the natural partner. If it is pooled traceability infrastructure at the scale of a large group, Aura Blockchain Consortium is designed for exactly that.
The digital product passport market will keep taking shape. The maisons that succeed with their project are not those that choose the best-known name. They are those that first named their problem precisely, then chose the building block designed to solve it.
