Building an MMO browser game on Matrix

Managing auth and saves in Matrix

<p>I'm working on a Massive Multiplayer Online (MMO) browser game which uses Matrix for authentication, authorization and storing save states. Lobbies and characters are managed as Matrix rooms which allows players to have a copy of their character's data at all times, migrate it to other Matrix accounts or share a character with friends.</p>
What if games allowed you to really own your online characters? If an online video game shuts down, your character is gone. All progress, all contacts, all items – lost to you and not available for migration. I'm building a tiny proof of concept browser game where you log in with your Matrix account. All your characters are represented by Matrix rooms and you can migrate them to other Matrix accounts and other gaming servers. Instead of sending all communication via Matrix this concept uses a public server software and central gaming servers (HTTP and websockets in this case). Upon character creation, a game server invites you to your character's room. Every time your character changes the server updates a state event. If the server gets shutdown, it's easy to set up a new server which allows to migrate character rooms from the old server. Furthermore, players can analyze their characters without the need to contact the gaming server.

<p>The Matrix core team is busier than ever, juggling hundreds of Matrix Spec Core Proposals and undergoing some major techtonic shifts as Matrix evolves into the ultimate secure decentralised communication network. In this talk, we'll give a high-level survey of the state of the core project, including: * How we're ensuring that flagship clients are as attractive as possible to a mainstream audience - and why we will fail if we don't. * How we're making Matrix go <em>fast</em> via v3 sync and ...

<p>Matrix has already got the solid framework of many bridge and bot implementations, but has always been missing that polish to make the bridges more accessible.</p> <p>In this talk, Will will explain how we're going to build our bridges with an all-new interactive interface and replacing old bot command interfaces with widget based interfaces.</p>

<p>Events are at the heart of the Matrix Protocol, but what are they? And how does the Protocol build on them to create rooms, room graphs, and other data structures? This talk aims to demystify some of these concepts, giving an overview of events, room event graphs, and associated structures. In the spirit of accessiblity, there will be an attempt to make the talk as approachable as possible for those without a ton of programming experience (although some basic knowledge will be helpful!). We ...

<p>A deep-dive into Sync v3: a super-fast API to sync Matrix clients with their homeserver. The talk is broken up into a brief history of syncing in Matrix to set the scene before we dive into the problem space and explore how Sync v3 is different and how it addresses one of the most important and complex parts of the Client-Server API: syncing.</p>

<p>Matrix (https://matrix.org) is an open protocol for secure, decentralised communication - defining an end-to-end-encrypted real-time communication layer for the open Web. Historically the network has been made up of newly written native Matrix clients, or bridges to 3rd party existing chat systems (e.g. Slack, Discord, Telegram).</p> <p>The matrix-rust-sdk is a modular Matrix client library, meant to be a robust implementation of the protocol, and to make even the most advanced features such ...

<p>Remarkably, the Matrix community still does not seem to have a equivalent to things like the venerable mIRCstats or PISG packages (which generate data based on a local IRC log). In this lightning talk, I'll present a new package I'm working on to present similar data for Matrix rooms. We'll have a quick demo and lots of pretty graphs to look at.</p>
