it feels we’re creeping ever closer to that goal of providing the missing communication layer for the open Web. The European Union’s Digital Markets Act (DMA) is a huge step in that direction - regulation that mandates that if the large centralised messaging providers are to operate in the EU, they must interoperate. We’ve been busy working away to make this a reality, including participating in the IETF for the first time as part of the MIMI working group - demonstrating concretely how (for instance) Android Messages could natively speak Matrix in order to interoperate with other services, while preserving end-to-end encryption.

The master key may also be used to sign other items such as the backup key

a master key (MSK) that serves as the user’s identity in cross-signing and signs their other cross-signing keys

In addition to connectivity, there are other Matrix-centric problems to be solved. In a world where each device is potentially running its own homeserver, we will need a new approach for handling user identities

Since federation within a Matrix room is effectively full-mesh, you need to be able to exchange data with all servers that are participating in a given room directly

As we discussed in #matrix-spec, since "rooms" are so much more than "chat rooms," and are really a DAG of events

In order to do this, a form of network-wide election takes place, where the node with the numerically highest ed25519 public key will win

Even though the Pinecone address space is considered to be global in scope, it is important to note that there is no true “single” Pinecone network. It is possible for multiple disjoint and disconnected Pinecone network segments to exist

In some cases, source addresses could be sealed/encrypted, although this is not implemented today

implement a better federation routing algorithm than full-mesh routing

but limiting the conference to 7 or 8 participants given all the duplication of the sent video required. In Element Call Beta 2, end-to-end encryption was enabled; easy, given it’s just a set of 1:1 calls.

So if the network roundtrip time to your server is even 100ms, and Sliding Sync is operating infinitely quickly, you’re still going to end up showing a placeholders for a few frames

Faster Joins (lazy-loading room state when your server joins a room)

111,873,374 matrix IDs on the public network, spanning 17,289,201 rooms, spread over 64,256 servers

All API endpoints within the specification are versioned individually. This means that /v3/sync (for example) can get deprecated in favour of /v4/sync without affecting /v3/profile at all. A server supporting /v4/sync would keep serving /v3/profile as it always has

For example, if /test were to be introduced in v1.1 and deprecated in v1.2, then it can be removed in v1.3.

Users may publish arbitrary key/value data associated with their account

Usage of an IS is not required in order for a client application to be part of the Matrix ecosystem. However, without one clients will not be able to look up user IDs using 3PIDs

file transfers

Every event graph has a single root event with no parent

type values MUST be uniquely globally namespaced following Java’s package naming conventions, e.g. com.example.myapp.event

In a mobile client, it might be acceptable to reuse the device if a login session expires, provided the user is the same

each device gets its own copy of the decryption keys

signing the message in the context of the graph for integrity

Room data is replicated across all of the homeservers whose users are participating in a given room

and shares data with the wider Matrix ecosystem by synchronising communication history with other homeservers and their clients

Computers are especially good at matrix multiplications. There is an entire industry around building computer hardware specifically for fast matrix multiplications. Any computation that can be expressed as a matrix multiplication can be made shockingly efficient.

um kevin anderson 00:12:43 if you can talk more about this issue both you and george assad raymond and so many other climate activists talking about this issue of wealth 00:12:55 you say per capita is a flawed metric as most polluting industries have been moved to developing nations so it's not reflective of the rich nation's emissions take all of this on 00:13:09 yeah i mean that's a really key issue and i think if i focus in here on the uk where i know it's a place obviously i know much better that what we've done in the uk we've closed down a lot of our industry and then we import the manufactured goods from elsewhere in the 00:13:22 world and then we turn around to those parts of the world and then we blame them for the emissions in manufacturing the goods that we are enjoying and that's everything from our electronic goods to parts for our cars as our clothes so you know the uk is 00:13:35 effectively moved to a bar and banking culture and and and offshore virtually everything else and so we when we looking at our total amount of emissions we have to take account of the carbon footprint of our lifestyles and that 00:13:47 does include the emissions that we associated with things that we import and export i mean you take that into account you tend to find that most wealthy countries have a much larger carbon footprint than when you just look at the energy they use within their 00:14:00 boundaries and i think it's really key again when we think about these issues of equity we we that we take this what's often referred to as a consumption-based accounting method we take that into account because it is unfair to be 00:14:12 penalizing poor parts of the world for them making things to help us have a better quality of life over here and when we do that then the challenges get even more striking in terms of what we have to do and it also also brings out 00:14:25 even further the issues of equity the disparity between the richer parts of the world and the poorer parts of the world but i also think on the equity point it's really worth bringing out that it's not as if everyone in the uk is even 00:14:37 there isn't just one public in the uk there are multiple publics there were those of us who are the wealthy ones in our own country that are responsible for the lion's share of missions within the uk that will be true chain for the u.s for germany for japan australia and so 00:14:50 within all of our countries there are large swathes of the country who are the average and below average consumers and for them the response to climate change is very different from those of us who are in our own countries are responsible for the lion's share of 00:15:03 emissions so i think we have to differentiate not just between countries but even within our countries and my concern there is that who are the people that frame the climate dubai debate they're the climate scientists and the academics they're the 00:15:14 entrepreneurs the business leaders the journalists the barristers they're all the people that are in the very high emitting category so we frame the debate and we never ever frame the debate with equity at its core and with regardless 00:15:26 of our maths or our moral sorry regardless of our moral position the maths tell us if we are to deliver on the commitments then equity has to be a key part of our responses but we never talk about that because we are in that 00:15:38 high emitting group

The true bottleneck to rapid detection methods remains the separation of a target analyte from a large complex matrix.

QUESTIONS TO BE ANSWERED!

Whilst this has been okay for our initial experimentation and proof of concept, it’s likely that future homeserver work will be written in a more strongly typed language (e.g. Go).

Can I run my own identity server? Yes - the reference implementation is sydent and you can run your own ID server cluster that tracks 3rd party to Matrix ID mappings. This won’t be very useful right now, though, and we don’t recommend it. If you want your server to participate in the global replicated Matrix ID service then please get in touch with us. Meanwhile, we are looking at ways of decentralising the ‘official’ Matrix identity service so that identity servers are 100% decentralised and can openly federate with each other. N.B. that you can use Matrix without ever using the identity service - it exists only to map 3rd party IDs (e.g. email addresses) to matrix IDs to aid user discovery.

End-to-end encryption is coming shortly to clients for both 1:1 and group chats to protect user data stored on servers, using the Olm cryptographic ratchet implementation.

Servers maintain a public/private key pair, and sign the integrity of all messages in the context of the historical conversation, preventing tampering.

How do I register custom matrix event types?

what is right for the consumer

Matrix is deliberately not a ‘pure’ peer-to-peer system; instead each user has a well-defined homeserver which stores his data and that he can depend upon.

It’s almost a contradiction in terms to get competitive between openly interoperable communication projects

by deploying their own server.

the whole web

Client<->Server API - defines how Matrix compatible clients communicate with Matrix homeservers. Server<->Server API - defines how Matrix homeservers exchange messages and synchronise history with each other.

It’s not actually incorporated anywhere at the moment but we are looking at the best legal structure for the future (and as of October 2015 we have hopefully found one). Whatever the legal structure, we are committed to keeping the Matrix project open.

We are called Matrix because we provide a structure in which all communication can be matrixed together.
