Protocols are “Commons”, Let’s Take Them Critically / ProcessOne
TLDR;
Thirty years after the arrival of the primary instantaneous messaging providers, we nonetheless haven’t reached the stage the place instantaneous messaging platforms can freely talk with one another, as is the case with e mail. In 1999, the Jabber/XMPP protocol was created and standardized for this function by the Web Engineering Process Power (IETF). Since then, proprietary messaging providers have repeatedly leveraged the facility of web giants to dominate the market. Why do neither XMPP nor the newer Matrix, which aimed to enhance upon it, break by this barrier, when it’s clear that protocols have to be open to allow change? With out this elementary precept, the Web itself wouldn’t exist.
Within the following article, I revisit how the French authorities just lately promoted the moment messaging service Olvid and what this reveals about our strategy to digital know-how. It’s irritating to see France promote a safe, but proprietary messaging service that provides no progress when it comes to interoperability, particularly at a time when the European Union is striving to open up the sector by requiring all messaging providers to be able to intercommunication, by the Digital Markets Act.
I conclude with reflections on our lack of ability in Europe to collaborate on “commons,” our problem in constructing a basis, an ecosystem that permits for wholesome co-opetition, a mix of competitors and collaboration, which is the one option to regain significance within the digital financial system. Quick-term political pondering forces our corporations into an every-man-for-himself strategy, preferring to dominate a small market reasonably than share a bigger one.
Right this moment, maybe, it’s time for a change?
Thirty years and counting because the emergence of the primary instantaneous messaging providers, we nonetheless lack a universally accepted change protocol, as is the case with e mail. The Jabber protocol, later renamed XMPP (eXtensible Messaging and Presence Protocol) and made a regular, was born with the hope of breaking the proliferation of remoted silos like MSN, ICQ, Yahoo!, which didn’t talk with one another. Right this moment, different silos have emerged, however the issue persists: it’s nonetheless unimaginable to change messages between accounts from totally different main messaging suppliers. Why? Let me let you know the story of a slipshod communication operation round a French messaging service, Olvid, which illustrates effectively the acquainted patterns we regularly discover ourselves caught in.
The French Authorities’s Endorsement of a Proprietary Messaging Service: A Nearer Look
I found the messaging service Olvid in late November 2023, following a flood of articles within the French press. I puzzled how an organization of 15 staff, created in 2019, had managed to get such press protection. It was promoted instantly by Prime Minister Elisabeth Borne: “Standard messaging purposes like WhatsApp, Telegram or Sign have ‘safety flaws’,” justified the workplace of Elisabeth Borne, who urged her ministers to obtain the French software.” (Les Échos, November 30, 2023). In November 2023, Matignon requested authorities members and ministerial places of work to put in this method on their telephones and computer systems “to exchange different instantaneous messaging providers to reinforce the safety of exchanges.” Then got here the superlatives: “Probably the most safe messaging service on the earth” (Jean-Noël Barrot). “A step in the direction of larger French sovereignty” (Elisabeth Borne). And it must be executed rapidly. Elisabeth Borne requested ministers to “take all vital steps” to deploy Olvid of their ministry “by December 8, 2023, on the newest” (Ouest France, November 29, 2023).
Why Olvid? The articles I learn on the topic stay comparatively imprecise; I do know primarily that it’s licensed by ANSII, the group guaranteeing the state’s IT safety. But, it’s removed from the primary safe messaging service I’ve come throughout, and it’s the primary time I’ve heard of Olvid. What about different providers and particularly Sign, which is acknowledged worldwide for its safety, backed by audits? Amongst safe messengers, the listing is lengthy: Sign, Threema, Wire, Berty, and so on. So, what safety flaws are we speaking about?
Sign Hits Again: A Robust Response to Safety Claims
Sign’s response was swift, with a direct and clear place from Meredith Whittaker, president of the Sign Basis:
The French PM is mandating ministers use a small French messaging app. OK. However I’m alarmed that she’s claiming “safety flaws” in Sign (et al) to justify the transfer. This declare is just not backed by any proof, and is dangerously deceptive esp. coming from gov.
If you wish to use a French product go for it! However don’t unfold misinfo within the course of. Sign is independently audited, open supply, and our protocol has been examined for >10yrs. We’re severe about accountable disclosure and we prioritize all experiences to safety@sign.org

Double Ratchet
Relating to Olvid’s safety, the primary argument appears to be as follows: The system doesn’t depend on centralized directories, operates with out identifiers, which suggests no person account is hosted within the cloud.
First, it appears to me that that is the precept of key-based authentication. Message routing is finished solely primarily based on a key, within the cryptographic sense. Whether it is misplaced, it’s unimaginable to recuperate the account. Nothing revolutionary, then; it’s cryptography, courting again to the encryption software program PGP (Fairly Good Privateness) of the Nineteen Nineties and even earlier than.
Then, such a system typically requires the bodily change of public keys. The place Olvid appears to face out is within the alternative routes proposed to simplify and lighten the burden of key change by assembly bodily. This will work, first as a result of the product is just not free, so the person base is restricted, the place Sign, for instance, gives a worldwide platform and says it wants an identifier, the cellphone quantity to restrict spam. Then, these various strategies depend on cell gadget administration (MDM) instruments, interfacing with an enterprise model of the Olvid server. In a technique or one other, this goes by a central level of distribution and reintroduces a weak point. It’s removed from a totally decentralized protocol like what the workforce constructing the Berty messaging service is making an attempt to do, as an illustration.
Shopping their website to seek out the protocol, I admit I choked a bit on some mentions thrown somewhat freely on their website, for instance, Put up Quantum Cryptography, cryptography that resists quantum computing. It’s good, it’s nice, however in apply, what’s the truth? I didn’t discover extra element beneath this point out, however personally, being hit with such buzzwords makes me reasonably flee, because it smells of a industrial who acquired a bit carried away. However let’s assume, the Olvid workforce consists of encryption consultants. I skimmed their specs, however I admit I’m not a mathematician, so who am I to evaluate their math formulation?
What I do perceive, nevertheless, is that the majority safe messaging methods, together with Olvid, depend on the Double Ratchet algorithm, which was first launched by… Sign.
On the Coronary heart of Messaging: The Essential Function of Protocols
When it comes to protocol, nevertheless, I’m an professional. I’ve been engaged on instantaneous messaging protocols since 1999. And, it’s not stunning… Olvid’s protocol is the antithesis of what I want to see in an formidable messaging protocol. It’s a proprietary, advert hoc protocol, not primarily based on any normal, minimalist for now, and condemns itself to reinventing the wheel, poorly. The burning query is, why not select an open protocol that already works on a big scale, like XMPP, including their worth on high? The Web protocol, TCP/IP, is open, all machines on the earth can talk, but there are competing web service suppliers. I’m nonetheless in search of a solution. As a result of XMPP is just too complicated, some will say? I feel any sufficiently superior chat protocol tends to turn out to be a by-product of XMPP, much less achieved. Come on, why not even use Matrix, a competing protocol to my favourite? Aside from easy ignorance, I see no purpose. Until it’s to lock down the platform, maybe? However, locking a communication protocol is not sensible. It’s replaying the battle of web protocols, TCP/IP versus X.25. A communication protocol is supposed to be open and interoperable. Personally, I’d invite Olvid to undertake a messaging normal. Allow them to flip to the W3C or IETF, to XMPP or MLS. These organizations do good work. And it’s a assure of sustainability and above all, of interoperability.
We come to a really sore level. The European Fee, and subsequently France as effectively, is discussing the implementation of the Digital Market Act. Among the many factors the European Union desires to impose is… the interoperability of instantaneous messaging providers. How can the French authorities promote a messaging answer that’s not interoperable? And ideally standardized and open.
I talked about Olvid’s proprietary protocol, which is definitely extra of an API (Utility Programming Interface), that’s, a doc that describes easy methods to automate sure capabilities of their server. What concerning the implementation? The consumer is open supply (on iOS and Android), however seeing of their change interface calls to URLs named /Freetrial. This means fee. I’m not certain that Olvid would welcome the thought of compiling and deploying one’s personal model of the consumer. That’s the precept of Open Supply, however such an initiative might attempt to circumvent funds to Olvid. As anyway, no open-source server is offered and the one one operating is operated by Olvid, the consumer code is of little use. Particularly because the consumer code is revealed by Olvid, however to what extent can we all know whether it is 100% equivalent to the model distributed within the iOS and Android app shops? We don’t actually have a approach of realizing.
I do know that Olvid guarantees at some point to launch the server as Open Supply. What I’ve seen of the protocol, their enterprise mannequin, and what they are saying about their implementation, very tied to the Amazon infrastructure (an infrastructure managed by an American firm, a lot for sovereignty), makes me assume that this won’t occur, no less than not for a really very long time. I hope, after all, to be fallacious.
Towards Openness and Collaboration in Digital Communication
Within the meantime? I would love us to be severe about instantaneous messaging, that lastly all gamers within the sector row in the identical route, those that work on open protocols, providing free servers and shoppers, that we construct actual collaboration, worthy of the development of web protocols, to construct the muse of a common, open, open-source and really interoperable messaging service. It doesn’t take a lot, to develop the tradition of “coopetition,” collaboration round a typical good between competing corporations.
