NIP-68
Shared Replaceables
draft optional
This NIP establishes the encoding mechanism to create, filter and reference replaceable events whose ownership are shared among several keys.
The initial creator adds all owners to the d tag, separated by |. The presence of | with valid keys for each but the last position, directs clients to work with this event as a shared replaceable.
{
"kind": 3xxxx,
"tags": [
["d", "<pubkey1>|<pubkey2>|<pubkey3>|<identifier>"],
// ...
],
//...
}
To change owners, users MUST create a new d tag with new owners and MAY delete the previous one.
Referencing & Indexing
Events that reference the most recent version of a shared replaceable MUST add a tags to each owner.
Reply example:
{
"kind": 1,
"tags": [
["a", "3xxxx:<pubkey1>:<pubkey1>|<pubkey2>|<pubkey3>|<identifier>", "<optional-relay-url>", "reply"],
["a", "3xxxx:<pubkey2>:<pubkey1>|<pubkey2>|<pubkey3>|<identifier>", "<optional-relay-url>", "reply"],
["a", "3xxxx:<pubkey3>:<pubkey1>|<pubkey2>|<pubkey3>|<identifier>", "<optional-relay-url>", "reply"]
],
"content": "a reply",
// ...
}
Deletion
Owners can only unilaterally delete their own events:
{
"pubkey": "<pubkey1>",
"kind": 5,
"tags": [
["a", "3xxxx:<pubkey1>:<pubkey1>|<pubkey2>|<pubkey3>|<identifier>", "<optional-relay-url>"],
],
"content": "Deletes my versions of this repleceable",
// ...
}
Adding other pubkeys to the a tag won't have any effect.
Filtering
After parsing the desired d tag, clients SHOULD create a filter that includes all d-tag pubkeys as authors and use the limit:1 to get only the latest event.
{
"authors": ["<pubkey1>", "<pubkey2>", "<pubkey3>"],
"kinds": [3xxxx],
"#d": ["<pubkey1>|<pubkey2>|<pubkey3>|<identifier>"],
"limit": 1
}
To find all events associated with a given shared replaceable, clients SHOULD search for a tags from each of the authors:
{
"#a": [
"3xxxx:<pubkey1>:<pubkey1>|<pubkey2>|<pubkey3>|<identifier>",
"3xxxx:<pubkey2>:<pubkey1>|<pubkey2>|<pubkey3>|<identifier>",
"3xxxx:<pubkey3>:<pubkey1>|<pubkey2>|<pubkey3>|<identifier>"
]
}
