Interactions

In order to come to an agreement, parties need to interact in some way. DIDComm Messaging is a standard for DIDs to safely interact. Ligo implements an application-level protocol on top of DIDComm Messaging that allows two DIDs to come to an agreement.

IPLD and IPLD Schemas are used to define messages. The following is the base schema for a DIDComm message.

type DIDCommMessageType string
type DID string

type AttachmentData struct {
    base64: String
}
type Attachment struct {
    id String
    data AttachmentData
}

type DIDCommMessage struct {  
    type DIDCommMessageType
    from optional DID
    to DID
    thid optional String
    pthid optional String
    id String
    expires_time optional String
    created_time optional String
    body Any
    attachments optional [Attachment]
}
