Confusion in protocol name
Hello, I came across the XMTP protocol (https://xmtp.org). It is a messaging protocol based on the blockchain, supported by Ephemera, a company with large fundings. The protocol is presented as "XMTP (Extensible Message Transport Protocol) is the largest and most secure decentralized messaging network". It seems to be confusing for the whole messaging community and I have a hard time imagining it is not on purpose. Should we, as the XSF, make a move ? We could ask the IETF if they also would want to join a letter of clarification. What do you think about it ? Kind regards, -- Mickaël Rémond
I have been wondering about this too. Most of the website including the documentation seemed LLM-generated to me and there are very few technical specifications to be found. That made me wonder whether it is worth bothering with it at all. But since it's supported by a well-funded company, seems to have known customers including Coinbase, and is actively looking for more funding, perhaps it's better to raise our voices regarding the name. This coverage by Fortune mentions "other decentralised messaging protocols" including Matrix, but makes no mention of XMPP: https://fortune.com/crypto/2025/07/17/xmtp-ephemera-messaging-protocol-union... I wonder if the authors of that article were just confused or didn't know that XMPP existed in the first place. Best, Badri
This appears to be a transcript of an interview with the person that has started the development on XMTP. The origin of the name is discussed, as being a combination of SMTP and XMTP. https://web3galaxybrain.com/episode/XMTP-with-Matt-Galligan I personally don't like the similarities of the naming (even in English pronunciation, the letters T and P are similar), but my first impression is not that it is malicious. It is going to be very, very confusing if this ever takes off. Given that there apparently is a source of investment, it could be argued that it already has taken off. From a quick scan, the project seems to be in ernest development for a reasonable amount of months (but not years) now. The longer that it is active (and the longer that the name XMTP is cemented in as their identity) the less likely it will be that they can be convinced that the similarities between the names are going to hurt both technologies more than that it is beneficial to them. If we do want to try and convince them to consider a name change, then I suggest we do so in the spirit of them too benefitting from a strong, not-to-be-confused-with-that-other-protocol identity, rather than from a get-off-my-lawn argument.

Quoting the relevant part from the transcript that Guus shared: Nicholas: Got it. The first thing I noticed about XMTP is the name, which reminds me of SMTP. Is there a reason for the relationship? Is it a reference, first of all? And if so, why? Matt Galligan: Yeah, it actually it's pretty spot on, but it goes one nerdy level deeper, which is there was also another protocol XMPP, sometimes referred to as the Jabber protocol. And when I was trying to think through what to call this thing, the one thing that stuck with me was that this was going to be a protocol where any kind of communication could happen on whether it be email or push notifications or DMs or whatnot. And so I did the very nerdy thing of just what are other protocols named? You know, what can make something feel immediately familiar, though you've never seen it before? And so looking at SMTP and XMPP, I was like, well, here you go. Here's two communication protocols. And I smashed them together. Doesn't go much deeper than that. But, you know, the value being like we've heard from a lot of folks that, you know, hey, I've never heard of XMPP before, but I'm assuming that it has to do with communication. So it serves a purpose for sure. I am now in agreement with Guus that the usage doesn't seem malicious. And even if it were, taking an aggressive stance would be less likely to convince them ;-) Having read more of the interview transcript, it's clear that the founder (Matt Gallighan) has used XMPP before and knows what he is talking about. There was also some thought (though minor) given to the naming, and it seems to have been chosen as a nod of acknowledgement to XMPP (and SMTP) rather than a rip-off. I'm still not entirely happy with the similarity personally, but I can live with it, and I'm curious to hear what others have to say. ~Badri
Hello, Thank you both for the research. Indeed, it is likely not badly intended, but still it is confusing. Maybe reaching out in a friendly manner would help to discuss and find a way to limit the confusion ? -- Mickaël Rémond ProcessOne Founder & CEO On 22 Jul 2025, at 11:12, Badri Sunderarajan wrote:
