# Matrix # Matrix
Matrix is a protocol for replicating a signed history of JSON objects in realtime across a set of nodes with (optional) end-to-end encryption. Matrix is a protocol for replicating a signed history of JSON objects in realtime across a set of nodes with (optional) end-to-end encryption. It was started in 2014.
### Identity ### Identity
Matrix has a more flexible identity solution than many decentralized protocols - users have a Matrix user ID, but can also use 3rd party IDs.
A matrix user ID includes the username along with the user's homeserver. For example: A matrix user ID includes the username along with the user's homeserver. For example:
`@bob:matrix.org` `@bob:matrix.org`
As for 3rd party IDs, a Matrix account can link to IDs such as email addresses, social accounts, and phone numbers. A globally federated cluster of trusted identity servers verify and replicate the mappings, although this is considered a stopgap solution until a fully decentralized identity solution is adopted. User accounts, once created on a homeserver, cannot be migrated. To change servers, a user must make a new account. [Automated tooling](https://modular.im/tools/matrix-migration) exists to help with inviting the new account into rooms the previous account was in.
Users have a Matrix user ID, but can also use 3rd party IDs. Matrix identity servers map 3rd party IDs such as email addresses, social accounts, and phone numbers to Matrix ids. The use of this service is optional.

User IDs used in conversations will soon be decoupled from permanent IDs, allowing one to decorrelate users from their messages. User IDs used in conversations will soon be decoupled from permanent IDs, allowing one to decorrelate users from their messages.

In the federated version of Matrix, all messages are currently sent out full-mesh within a conversation. A node broadcasts in parallel to every other node present in the room. Experimental work on stochastic spanning tree "fan-out" approaches to improve efficiency are being researched.

30% of publicly visible users are on the matrix.org homeserver. There are many smaller servers as well.
#### P2p #### P2p
Matrix has released a p2p version that runs client-side. P2p Matrix avoids the problem of homeservers accumulating metadata, and simplifies signup by not requiring new users to pick a homeserver. The new p2p implementation runs the homeserver on the client. The p2p network is currently separate from the federated network, but the end goal is to connect the two in a hybrid federated/p2p model. Network transports being considered for p2p Matrix include libp2p, Yggdrasil, or hyperswarm. Matrix has released a p2p version that runs client-side.

A Matrix "room" refers to a persistent pubsub topic. Users who want to chat join the same room, and their conversation history is then replicated on each user's server.
### Moderation & Reputation ### Moderation & Reputation
The Matrix team has been working intensively on tools for moderation, detailed [here](https://matrix.org/docs/guides/moderation/). The Matrix team has been working intensively on tools for moderation, detailed [here](https://matrix.org/docs/guides/moderation/).
Most moderation takes place at the room level. Rooms have moderators who can remove undesirable content. A redaction, or 'remove message', can request all participating servers to remove a message. Users can also remove their own messages. However, due to the decentralized nature of Matrix, if the client does not remove the redaction, the message will not be removed. Moderators can kick or ban users from rooms. They can also ban servers from rooms, in cases where malicious traffic must be avoided. Most moderation takes place at the room level.

Users in a room have 'power levels', a number between 0 and 100 that indicates how much power the user has in the room. A higher level has more permissions. Moderators have ability to change power level permissions. Users can report abusive content to the server admin, which has the ability to remove it. Users can also block other users to prevent them from contacting them. Users in a room have 'power levels', a number between 0 and 100 that indicates how much power the user has in the room.
