# SIGit

## Flow
 
  - Create Event
  - Sign Event
  - COMPLETE EVENT

---

sigit is made up of:

 - pointers, notifications, components (events) 
 - files (encrypted blobs)
 - all events are private (giftwrapped)




## Create Event Component - kind X1

Signer should display:  
```
You are signing an Agreement template for the following npubs:
- npub1
- npub2

Ensure this event is sourced from a trusted SIGit instance.
```

- Signed by Creator
- NOT published by default
- fileData{}
- counterpartyData{}
- markData{}

This data is all stored inside the X1 blob
Verifications take place on all the elements in X2 (todo: list them)



---

##  File pointer 

Signer should say:  "You are verifying that the following files exist:"

And list the full urls (blossom url + hash)

 - signed by sender
 - NOT PUBLISHED by default
 - points to encrypted blossom blob (BB)

```json
{"content":"",
 "kind": XX, --tbd
 "tags"[ 
   
   ["filehash","$(hash)"],
   ["blossomUrls","url1","blossom2"], --optional
   ["engine": "SIGIT"]
 ] 
}
```

Contains:
 - Create Event 
 - Files
