62/STATUS-Payloads

Abstract​

This specification describes how the payload of each message in Status looks like. It is primarily centered around chat and chat-related use cases.

The payloads aims to be flexible enough to support messaging but also cases described in the Status Whitepaper as well as various clients created using different technologies.

Wire Format Specification​

Payload wrapper​

The node wraps all payloads in a protobuf record record:

message StatusProtocolMessage {
  bytes signature = 4001;
  bytes payload = 4002;
}

signature is the bytes of the signed SHA3-256 of the payload, signed with the key of the author of the message. The node needs the signature to validate authorship of the message, so that the message can be relayed to third parties. If a signature is not present, but an author is provided by a layer below, the message is not to be relayed to third parties, and it is considered plausibly deniable.

Encoding​

The node encodes the payload using Protobuf

Types of messages​

ChatMessage​

The type ChatMessage represents a chat message exchanged between clients.

Payload​

The protobuf description is:

message ChatMessage {
  // Lamport timestamp of the chat message
  uint64 clock = 1;
  // Unix timestamps in milliseconds, currently not used as we use whisper as
  // more reliable, but here so that we don't rely on it
  uint64 timestamp = 2;
  // Text of the message
  string text = 3;
  // Id of the message that we are replying to
  string response_to = 4;
  // Ens name of the sender
  string ens_name = 5;
  // Chat id, this field is symmetric for public-chats and private group chats,
  // but asymmetric in case of one-to-ones, as the sender will use the chat-id
  // of the received, while the receiver will use the chat-id of the sender.
  // Probably should be the concatenation of sender-pk & receiver-pk in
  // alphabetical order
  string chat_id = 6;

  // The type of message (public/one-to-one/private-group-chat)
  MessageType message_type = 7;
  // The type of the content of the message
  ContentType content_type = 8;

  oneof payload {
    StickerMessage sticker = 9;
    ImageMessage image = 10;
    AudioMessage audio = 11;
    bytes community = 12;
    DiscordMessage discord_message = 99;
  }

  // Grant for community chat messages
  bytes grant = 13;

  // Message author's display name, introduced in version 1
  string display_name = 14;

  ContactRequestPropagatedState contact_request_propagated_state = 15;

  repeated UnfurledLink unfurled_links = 16;

  enum ContentType {
    UNKNOWN_CONTENT_TYPE = 0;
    TEXT_PLAIN = 1;

Content types​

A node requires content types for a proper interpretation of incoming messages. Not each message is plain text but may carry different information.

The following content types MUST be supported:

  • TEXT_PLAIN identifies a message which content is a plaintext.

There are other content types that MAY be implemented by the client:

  • STICKER
  • STATUS
  • EMOJI
  • TRANSACTION_COMMAND
  • IMAGE
  • AUDIO
  • COMMUNITY
  • CONTACT_REQUEST
  • DISCORD_MESSAGE
  • IDENTITY_VERIFICATION
Mentions​

A mention MUST be represented as a string with the @0xpk format, where pk is the public key of the user account to be mentioned, within the text field of a message with content_type TEXT_PLAIN. A message MAY contain more than one mention. This specification RECOMMENDs that the application does not require the user to enter the entire pk. This specification RECOMMENDs that the application allows the user to create a mention by typing @ followed by the related ENS or 3-word pseudonym. This specification RECOMMENDs that the application provides the user auto-completion functionality to create a mention. For better user experience, the client SHOULD display a known ens name or the 3-word pseudonym corresponding to the key instead of the pk.

Sticker content type​

A ChatMessage with STICKER Content/Type MUST also specify the ID of the Pack and the Hash of the pack, in the Sticker field of ChatMessage

message StickerMessage {
  string hash = 1;
  int32 pack = 2;
}
Image content type​

A ChatMessage with IMAGE Content/Type MUST also specify the payload of the image and the type.

Clients MUST sanitize the payload before accessing its content, in particular:

  • Clients MUST choose a secure decoder
  • Clients SHOULD strip metadata if present without parsing/decoding it
  • Clients SHOULD NOT add metadata/exif when sending an image file for privacy and security reasons
  • Clients MUST make sure that the transport layer constraints the size of the payload to limit they are able to handle securely
message ImageMessage {
  bytes payload = 1;
  ImageType type = 2;
  enum ImageType {
    UNKNOWN_IMAGE_TYPE = 0;
    PNG = 1;
    JPEG = 2;
    WEBP = 3;
    GIF = 4;
  }
}
Audio content type​

A ChatMessage with AUDIO Content/Type MUST also specify the payload of the audio, the type and the duration in milliseconds (duration_ms).

Clients MUST sanitize the payload before accessing its content, in particular:

  • Clients MUST choose a secure decoder
  • Clients SHOULD strip metadata if present without parsing/decoding it
  • Clients SHOULD NOT add metadata/exif when sending an audio file for privacy and security reasons
  • Clients MUST make sure that the transport layer constraints the size of the payload to limit they are able to handle securely
message AudioMessage {
  bytes payload = 1;
  AudioType type = 2;
  uint64 duration_ms = 3;
  enum AudioType {
    UNKNOWN_AUDIO_TYPE = 0;
    AAC = 1;
    AMR = 2;
Community content type​

A ChatMessage with COMMUNITY Content/Type MUST also specify the payload of the community as bytes from a CommunityDescription.

DiscordMessage content type​

A ChatMessage with DISCORD_MESSAGE Content/Type MUST also specify the payload of the DiscordMessage.

message DiscordMessage {
  string id = 1;
  string type = 2;
  string timestamp = 3;
  string timestampEdited = 4;
  string content = 5;
  DiscordMessageAuthor author = 6;
  DiscordMessageReference reference = 7;
  repeated DiscordMessageAttachment attachments = 8;
}

message DiscordMessageAuthor {
  string id = 1;
  string name = 2;
  string discriminator = 3;
  string nickname = 4;
  string avatarUrl = 5;
  bytes avatarImagePayload = 6;
  string localUrl = 7;
}

message DiscordMessageReference {
  string messageId = 1;
  string channelId = 2;
  string guildId = 3;
}

message DiscordMessageAttachment {
  string id = 1;
  string messageId = 2;
  string url = 3;
  string fileName = 4;
  uint64 fileSizeBytes = 5;
  string contentType = 6;
  bytes payload = 7;
  string localUrl = 8;
}

Message types​

A node requires message types to decide how to encrypt a particular message and what metadata needs to be attached when passing a message to the transport layer. For more on this, see 10/WAKU2.

The following messages types MUST be supported:

  • ONE_TO_ONE is a message to the public group
  • PUBLIC_GROUP is a private message
  • PRIVATE_GROUP is a message to the private group.
  • COMMUNITY_CHAT is a message to a community channe.
enum MessageType {
  UNKNOWN_MESSAGE_TYPE = 0;
  ONE_TO_ONE = 1;
  PUBLIC_GROUP = 2;
  PRIVATE_GROUP = 3;
  // Only local
  SYSTEM_MESSAGE_PRIVATE_GROUP = 4;
  COMMUNITY_CHAT = 5;
  // Only local
  SYSTEM_MESSAGE_GAP = 6;
}

Clock vs Timestamp and message ordering​

If a user sends a new message before the messages sent while the user was offline are received, the new message is supposed to be displayed last in a chat. This is where the basic algorithm of Lamport timestamp would fall short as it's only meant to order causally related events.

The status client therefore makes a "bid", speculating that it will beat the current chat-timestamp, s.t. the status client's Lamport timestamp format is: clock = max({timestamp}, chat_clock + 1)`

This will satisfy the Lamport requirement, namely: a -> b then T(a) < T(b)

timestamp MUST be Unix time calculated, when the node creates the message, in milliseconds. This field SHOULD not be relied upon for message ordering.

clock SHOULD be calculated using the algorithm of Lamport timestamps. When there are messages available in a chat, the node calculates clock's value based on the last received message in a particular chat: max(timeNowInMs, last-message-clock-value + 1). If there are no messages, clock is initialized with timestamp's value.

Messages with a clock greater than 120 seconds over the Whisper/Waku timestamp SHOULD be discarded, in order to avoid malicious users to increase the clock of a chat arbitrarily.

Messages with a clock less than 120 seconds under the Whisper/Waku timestamp might indicate an attempt to insert messages in the chat history which is not distinguishable from a datasync layer re-transit event. A client MAY mark this messages with a warning to the user, or discard them.

The node uses clock value for the message ordering. The algorithm used, and the distributed nature of the system produces casual ordering, which might produce counter-intuitive results in some edge cases. For example, when a user joins a public chat and sends a message before receiving the exist messages, their message clock value might be lower and the message will end up in the past when the historical messages are fetched.

Chats​

Chat is a structure that helps organize messages. It's usually desired to display messages only from a single recipient, or a group of recipients at a time and chats help to achieve that.

All incoming messages can be matched against a chat. The below table describes how to calculate a chat ID for each message type.

Message TypeChat ID CalculationDirectionComment
PUBLIC_GROUPchat ID is equal to a public channel name; it should equal chatId from the messageIncoming/Outgoing
ONE_TO_ONElet P be a public key of the recipient; hex-encode(P) is a chat ID; use it as chatId value in the messageOutgoing
user-messagelet P be a public key of message's signature; hex-encode(P) is a chat ID; discard chat-id from messageIncomingif there is no matched chat, it might be the first message from public key P; the node MAY discard the message or MAY create a new chat; Status official clients create a new chat
PRIVATE_GROUPuse chatId from the messageIncoming/Outgoingfind an existing chat by chatId; if none is found, the user is not a member of that chat or the user hasn't joined that chat, the message MUST be discarded
COMMUNITY_CHATuse chatId from the messageIncoming/Outgoingfind existing community chat within a community based on chatId; the chatId includes a community id prefix

ContactUpdate​

ContactUpdate is a message exchange to notify peers that either the user has been added as a contact, or that information about the sending user have changed.

message ContactUpdate {
  uint64 clock = 1;
  string ens_name = 2;
  string profile_image = 3;
  string display_name = 4;
  uint64 contact_request_clock = 5;
  ContactRequestPropagatedState contact_request_propagated_state = 6;
  string public_key = 7;
}

message ContactRequestPropagatedState {
  uint64 local_clock = 1;
  uint64 local_state = 2;
  uint64 remote_clock = 3;
  uint64 remote_state = 4;
}

Payload​

FieldNameTypeDescription
1clockuint64The clock of the chat with the user
2ens_namestringThe ENS name if set
3profile_imagestringThe base64 encoded profile picture of the user
4display_namestringThe display name of the user
5contact_request_clockuint64The clock at which a contact request was sent
6contact_request_propagated_stateContactRequestPropagatedStateAdditional propagation clock values
7public_keystringThe public key of the user

Contact update​

A client SHOULD send a ContactUpdate to all the contacts each time:

  • The ens_name has changed
  • A user edits the profile image

A client SHOULD also periodically send a ContactUpdate to all the contacts, the interval is up to the client, the Status official client sends these updates every 48 hours.

EmojiReaction​

EmojiReactions represents a user's "reaction" to a specific chat message. For more information about the concept of emoji reactions see Facebook Reactions.

This specification RECOMMENDS that the UI/UX implementation of sending EmojiReactions requires only a single click operation, as users have an expectation that emoji reactions are effortless and simple to perform. 

message EmojiReaction {
  // clock Lamport timestamp of the chat message
  uint64 clock = 1;

  // chat_id the ID of the chat the message belongs to, for query efficiency the chat_id is stored in the db even though the
  // target message also stores the chat_id
  string chat_id = 2;

  // message_id the ID of the target message that the user wishes to react to
  string message_id = 3;

  // message_type is (somewhat confusingly) the ID of the type of chat the message belongs to
  MessageType message_type = 4;

  // type the ID of the emoji the user wishes to react with
  Type type = 5;

  enum Type {
    UNKNOWN_EMOJI_REACTION_TYPE = 0;
    LOVE = 1;
    THUMBS_UP = 2;
    THUMBS_DOWN = 3;
    LAUGH = 4;
    SAD = 5;
    ANGRY = 6;
  }

 // whether this is a retraction of a previously sent emoji
  bool retracted = 6;
}

Clients MUST specify clock, chat_id, message_id, type and message_type.

This specification RECOMMENDS that the UI/UX implementation of retracting an EmojiReactions requires only a single click operation, as users have an expectation that emoji reaction removals are effortless and simple to perform.

MembershipUpdateMessage and MembershipUpdateEvent​

MembershipUpdateEvent is a message used to propagate information about group membership changes in a group chat. The details are in the Group chats specs.

message MembershipUpdateMessage {
  // The chat id of the private group chat
  string chat_id = 1;
  // A list of events for this group chat, first x bytes are the signature, then is a 
  // protobuf encoded MembershipUpdateEvent
  repeated bytes events = 2;

  // An optional chat message
  oneof chat_entity {
    ChatMessage message = 3;
    EmojiReaction emoji_reaction = 4;
  }
}

message MembershipUpdateEvent {
  // Lamport timestamp of the event
  uint64 clock = 1;
  // List of public keys of objects of the action
  repeated string members = 2;
  // Name of the chat for the CHAT_CREATED/NAME_CHANGED event types
  string name = 3;
  // The type of the event
  EventType type = 4;
  // Color of the chat for the CHAT_CREATED/COLOR_CHANGED event types
  string color = 5;
  // Chat image
  bytes image = 6;

  enum EventType {
    UNKNOWN = 0;
    CHAT_CREATED = 1;
    NAME_CHANGED = 2;
    MEMBERS_ADDED = 3;
    MEMBER_JOINED = 4;
