|
|
#### Internet Relay Chat daemon: *Matrix Construct*
|
|
|
|
IRCd was a free and open source server which facilitated real-time communication over the
|
|
internet. It was started by Jarkko Oikarinen in 1988 at the University of Oulu and [its
|
|
derivatives](https://upload.wikimedia.org/wikipedia/commons/d/d8/IRCd_software_implementations.png)
|
|
underpinned the major IRC networks for decades.
|
|
|
|
Due to its age and stagnation since the mid-2000's, a growing number of proprietary cloud services
|
|
are now filling the vacuum of innovation. In 2014 a new approach was proposed to reinvigorate
|
|
real-time communication for free and open source software: a *federation of networks* known as
|
|
*the matrix*.
|
|

|
|
|
|
**This is the Construct** — the first Matrix server written in C++. It is designed to be
|
|
fast and highly scalable, and to be community developed by volunteer contributors over
|
|
the internet. This mission strives to make the software easy to understand, modify, audit,
|
|
and extend. It remains true to its roots with its modular design and having minimal
|
|
requirements. Even though all of the old code has been rewritten, the same spirit and
|
|
_philosophy of its predecessors_ is still obvious throughout.
|
|
|
|
Similar to the legacy IRC protocol's origins, Matrix wisely leverages technologies in vogue
|
|
for its day to aid the virility of implementations. A vibrant and growing ecosystem
|
|
[already exists](https://matrix.org/docs/projects/try-matrix-now.html).
|
|
|
|
## Installation
|
|
|
|
Getting up and running with Construct is easy. A deployment can scale from as little as
|
|
a low-end virtual machine running a stock linux distribution to a large load balanced
|
|
cluster operating in synchrony over a network.
|
|
|
|
|
|

|
|
|
|

|
|
|
|
*Notes*:
|
|
- libircd requires a platform capable of loading dynamic shared objects at runtime.

### Building from git (production)
|
|
|
|
```
|
|
./autogen.sh
|
|
./configure
|
|
make
|
|
sudo make install
|
|
```
|
|
|
|
|
|
#### Building from git (DEVELOPER PREVIEW INSTRUCTIONS)
|
|
|
|
*This is only intended to allow development with dependencies that have not made
|
|
their way to mainstream systems yet.* **Not for release.**
|
|
|
|
The developer preview will install Construct in a specific directory isolated from the
|
|
system. It will avoid using system libraries by downloading and building the dependencies
|
|
from the submodules we have pinned here and build them the way we have configured. You may
|
|
need to set the `LD_LIBRARY_PATH` to the built libraries and/or maintain an intact build
|
|
directory.
|
|
|
|
```
|
|
./autogen.sh
|
|
mkdir build
|
|
```
|
|
|
|
- The install directory may be this or another place of your choosing.
|
|
- If you decide elsewhere, make sure to change the `--prefix` in the `./configure`
|
|
statement below.
|
|
|
|
```
|
|
CXX=g++-6 ./configure --prefix=$PWD/build --enable-debug --with-included-boost=shared --with-included-rocksdb=shared
|
|
```
|
|
|
|
- Many systems alias `g++` to an older version. To be safe, specify a version manually
|
|
in `CXX`. This will also build the submodule dependencies with that version.
|
|
- The `--with-included-*` will fetch, configure **and build** the dependencies included
|
|
as submodules. Include `=shared` for now until static libraries are better handled.
|
|
|
|
```
|
|
make
|
|
make install
|
|
```
|
|
|

## Plan
|
|
|
|
#### Roadmap for service
|
|
|
|
- [x] **Phase One**: Matrix clients using HTTPS.
|
|
- [ ] **Phase Two**: Legacy IRC networks using TS6 protocol.
|
|
- [ ] **Phase Three**: Legacy IRC clients using RFC1459 / RFC2812 legacy grammars.
|
|
|
|
#### Roadmap for deployments
|
|
|
|
The deployment mode is a macro of configuration variables which tune the daemon
|
|
for how it is being used. Modes mostly affect aspects of local clients.
|
|
|
|
- [x] **Personal**: One or few users. Few default restrictions; higher log output.
|
|
- [ ] **Company**: Hundreds of users. Moderate default restrictions.
|
|
- [ ] **Public**: Thousands of users. Untrusting configuration defaults.
|
|
|
|
#### Roadmap for innovation
|
|
|
|
- [x] Phase Zero: **Core libircd**: Utils; Modules; Contexts; JSON; Database; HTTP; etc...
|
|
- [x] Phase One: **Matrix Protocol**: Core VM; Core modules; Protocol endpoints; etc...
|
|
- [ ] Phase Two: **Construct Cluster**: Kademlia sharding of events; Maymounkov's erasure codes.
|
|
|
|
##### Experimental section
|
|
|
|
- [ ] Phase Three: **Graduate Seminar**
|
|
- Tromer/Virza's zkSNARK applied to JavaScript XDR evaluation verifying the distributed
|
|
execution of a matrix room using MNT pairing curves.
|
|
|
|
- [ ] Phase Four: **Dissertation Defense**
|
|
- Phase Three _with RingLWE_; GPU accelerated matrix multiplication for
|
|
the number theoretic transform...
|
|
|
|
- [ ] Phase Five: **Habilitation**
|
|
- Phase Four _under fully homomorphic encryption_.
|

### IRCd Library
|
|
|
|
This library can be embedded by developers creating their own server or those
|
|
who simply want to use the library of routines it provides.
|
|
|
|
Including libircd headers will not include any other headers beyond those in
|
|
the standard library, with minimal impact on your project's compile complexity.
|
|
The prototypical embedding of `libircd` is `construct` found in the
|
|
`construct/` directory.
|
|
|
|
- Can be embedded in your application with very minimal overhead.
|
|
|
|
- Runs only one server at a time.
|
|
|
|
- Is asynchronous and single-threaded✝.
|
|
|
|
- Introduces its own userspace threading.
|
|
|
|
- Leverages fast & safe formal grammars.
|
|
|
|
See the `include/ircd/` and `ircd/` directories for more information.
