twister group chat draft
|
||
|
|
========================
|
||
|
|
|
||
|
|
group chat is a private and encrypted timeline shared among some users
|
||
|
|
which define a specific topic (or description).
|
||
|
|
|
||
|
|
it is tempting to use a new torrent where members would subscribe in
|
||
|
|
order to post their chat messages. however this idea does work as it is
|
||
|
|
impossible (very difficult?) to implement a distributed torrent with
|
||
|
|
multiple writers. (a clash occurs when two writers try to send the
|
||
|
|
same piece number)
|
||
|
|
|
||
|
|
therefore, twister's group chat is a special case of direct messages
|
||
|
|
using a private key pair (outside of the blockchain). non-members do not
|
||
|
|
know about group chat creation as public key is never published.
|
||
|
|
|
||
|
|
members are invited to group using a special (bencoded) group_invite DM:
|
||
|
|
|
||
|
|
group_invite {
|
||
|
|
desc: "free text description",
|
||
|
|
key: "secret of the private key",
|
||
|
|
}
|
||
|
|
|
||
|
|
after sending the group_invite DM to a given user, another DM is sent
|
||
|
|
to the group itself to notify all existing members about the new
|
||
|
|
member list. this is another special DM:
|
||
|
|
|
||
|
|
group_members {
|
||
|
|
[xxx,yyy,...]
|
||
|
|
}
|
||
|
|
|
||
|
|
it is true that, since every member knows both private/public keys of
|
||
|
|
the group, symmetric-key could have been used for group chat's messages.
|
||
|
|
however we reuse the same twister infrastructure of original DMs.
|
||
|
|
any group chats, invites and messages are indistinguible from normal
|
||
|
|
DMs to non-members.
|
||
|
|
|
||
|
|
because all members have access to private key, there is no concept of
|
||
|
|
administrator. any member may invite new members and change group's
|
||
|
|
description. it is not possible to exclude a member, so frontends may
|
||
|
|
offer an option to clone/create a new group excluding whoever they
|
||
|
|
want.
|
||
|
|

|
new RPCs for group chat:
|
||
|
|
|
||
|
|
- creategroup <description>
|
||
|
|
returns groupalias (which is added to wallet).
|
||
|
|
|
||
|
|
group aliases are prepended with "*" so they are not valid usernames
|
||
|
|
and may not be propagated accidentaly to the network.
|
||
|
|
|
||
|
|
group aliases are only valid locally, each twisterd instance will
|
||
|
|
create its own alias upon receiving an invitation.
|
||
|
|
|
||
|
|
- listgroups
|
||
|
|
[ groupalias1, groupalias2, ... ]
|
||
|
|
|
||
|
|
- getgroupinfo
|
||
|
|
{alias:xxx,description:xxx,members:[xxx,yyy,...]}
|
||
|
|
|
||
|
|
- newgroupinvite <username> <k> <groupalias> [<newmember1>,<newmember2>,...]
|
||
|
|
DM(group_invite) => newmember
|
||
|
|
DM(group_members) => groupalias
|
||
|
|
|
||
|
|
- newgroupdescription <username> <k> <groupalias> <description>
|
||
|
|
DM(group_invite) => groupalias
|
||
|
|
|
||
|
|
- leavegroup <username> <groupalias>
|
||
|
|
not yet implemented
|
||
|
|
|
||
|
|
note: use getdirectmsgs/newdirectmsgto to obtain/post new messages
|
||
|
|
to group chats.
