This NIP defines an encrypted chat scheme which uses [NIP-44](44.md) encryption and [NIP-59](59.md) seals and gift wraps.
This NIP defines an encrypted direct messaging scheme using [NIP-44](44.md) encryption and [NIP-59](59.md) seals and gift wraps.
Any event sent to an encrypted chat MUST NOT be signed, and MUST be encrypted as described in [NIP-59](./59.md) and illustrated below. Omitting signatures makes messages deniable in case they are accidentally or maliciously leaked, while still allowing the recipient to authenticate them.
By convention, `kind 14` direct messages, `kind 15` file messages, and [`kind 7` reactions](./25.md) may be sent to an encrypted chat.

The main limitation of this approach is having to send a separate encrypted event to each receiver. Group chats with more than 100 participants should find a more suitable messaging scheme.
## Implementation
Clients implementing this NIP should by default only connect to the set of relays found in their `kind:10050` list. From that they should be able to load all messages both sent and received as well as get new live updates, making it for a very simple and lightweight implementation that should be fast.
When sending a message to anyone, clients must then connect to the relays in the receiver's `kind:10050` and send the events there but can disconnect right after unless more messages are expected to be sent (e.g. the chat tab is still selected). Clients should also send a copy of their outgoing messages to their own `kind:10050` relay set.

Relay Access Metadata and Requests
----------------------------------
`draft` `optional`
This NIP defines a way for relays to advertise membership lists, and for clients to request admission to relays on behalf of users.
## Membership Lists
Relays MAY publish a `kind 13534` event which indicates pubkeys that have access to a given relay. This event MUST be signed by the pubkey specified in the `self` field of the relay's [NIP 11](./11.md) document.
The following tags are required:
- A [NIP 70](./70.md) `-` tag
- A `member` tag containing a hex pubkey should be included for each member
This list should not be considered exhaustive or authoritative. To determine membership, both a `kind 13534` event by the relay, and a `kind 10010` event by the member should be consulted.
Example:
```jsonc
{
"kind": 13534,
"pubkey": "<nip11.self>",
"tags": [
["-"],
["member", "c308e1f882c1f1dff2a43d4294239ddeec04e575f2d1aad1fa21ea7684e61fb5"],
["member", "ee1d336e13779e4d4c527b988429d96de16088f958cbf6c074676ac9cfd9c958"]
],
// ...other fields
}
```
## Add User
Relays MAY publish a `kind 8000` event when a member is added to the relay. This event MUST be signed by the pubkey specified in the `self` field of the relay's [NIP 11](./11.md) document.
The following tags are required:
- A [NIP 70](./70.md) `-` tag
- A `p` tag indicating the member's hex pubkey
Example:
```jsonc
{
"kind": 8000,
"pubkey": "<nip11.self>",
"tags": [
["-"],
["p", "c308e1f882c1f1dff2a43d4294239ddeec04e575f2d1aad1fa21ea7684e61fb5"]
],
// ...other fields
}
```
## Remove User
Relays MAY publish a `kind 8001` event when a member is removed from the relay. This event MUST be signed by the pubkey specified in the `self` field of the relay's [NIP 11](./11.md) document.
The following tags are required:
- A [NIP 70](./70.md) `-` tag
- A `p` tag indicating the member's hex pubkey
Example:
```jsonc
{
"kind": 8001,
"pubkey": "<nip11.self>",
"tags": [
["-"],
["p", "c308e1f882c1f1dff2a43d4294239ddeec04e575f2d1aad1fa21ea7684e61fb5"]
],
// ...other fields
}
```
## Join Request
A user MAY send a `kind 28934` to a relay in order to request admission. It MUST have a `claim` tag containing an invite code. The event's `created_at` MUST be now, plus or minus a few minutes.
```jsonc
{
"kind": 28934,
"pubkey": "<user pubkey>",
"tags": [
["-"],
["claim", "<invite code>"]
],
// ...other fields
}
```
Upon receiving a claim, a relay MUST notify the client as to what the status of the claim is using an `OK` message. Failed claims SHOULD use the same standard `"restricted: "` prefix specified by NIP 42.
Relays SHOULD update their `kind 13534` member list and MAY publish a `kind 8000` "add member" event.
Some examples:
```
["OK", <event-id>, false, "restricted: that invite code is expired."]
["OK", <event-id>, false, "restricted: that is an invalid invite code."]
["OK", <event-id>, true, "duplicate: you are already a member of this relay."]
["OK", <event-id>, true, "info: welcome to wss://relay.bunk.skunk!"]
```
## Invite Request
Users may request a claim string from a relay by making a request for `kind 28935` events. This event MUST be signed by the pubkey specified in the `self` field of the relay's [NIP 11](./11.md) document.
```jsonc
{
"kind": 28935,
"pubkey": "<nip11.self>",
"tags": [
["-"],
["claim", "<invite code>"],
],
// ...other fields
}
```
Note that these events are in the `ephemeral` range, which means relays must explicitly opt-in to this behavior by generating claims on the fly when requested. This allows relays to improve security by issuing a different claim for each request, only issuing claims to certain users, or expiring claims.
## Leave Request
A user MAY send a `kind 28936` to a relay in order to request that their access be revoked. The event's `created_at` MUST be now, plus or minus a few minutes. This event MUST include a [NIP 70](./70.md) `-` tag.
```jsonc
{
"kind": 28936,
"tags": [["-"]],
// ...other fields
}
```
Relays SHOULD update their `kind 13534` member list and MAY publish a `kind 8001` "remove member" event.
## Implementation
Clients MUST only request `kind 28935` events from and send `kind 28934` events to relays which include this NIP in the `supported_nips` section of its [NIP 11](./11.md) relay information document.

## Filters and return values

This NIP defines the verb `COUNT`, which accepts a subscription id and filters as specified in [NIP 01](01.md) for the verb `REQ`. Multiple filters are OR'd together and aggregated into a single count result.
```
["COUNT", <query_id>, <filters JSON>...]
["COUNT", <subscription_id>, <filters JSON>...]
```
Counts are returned using a `COUNT` response in the form `{"count": <integer>}`. Relays may use probabilistic counts to reduce compute requirements.
In case a relay uses probabilistic counts, it MAY indicate it in the response with `approximate` key i.e. `{"count": <integer>, "approximate": <true|false>}`.
```
["COUNT", <query_id>, {"count": <integer>}]
["COUNT", <subscription_id>, {"count": <integer>}]
```
Whenever the relay decides to refuse to fulfill the `COUNT` request, it MUST return a `CLOSED` message.
## HyperLogLog
Relays may return an HyperLogLog value together with the count, hex-encoded.
```
["COUNT", <query_id>, {"count": <integer>, "hll": "<hex>"}]
```
This is so it enables merging results from multiple relays and yielding a reasonable estimate of reaction counts, comment counts and follower counts, while saving many millions of bytes of bandwidth for everybody.
### Algorithm
This section describes the steps a relay should take in order to return HLL values to clients.
1. Upon receiving a filter, if it is eligible (see below) for HyperLogLog, compute the deterministic `offset` for that filter (see below);
2. Initialize 256 registers to `0` for the HLL value;
3. For all the events that are to be counted according to the filter, do this:
1. Read the byte at position `offset` of the event `pubkey`, its value will be the register index `ri`;
2. Count the number of leading zero bits starting at position `offset+1` of the event `pubkey` and add `1`;
3. Compare that with the value stored at register `ri`, if the new number is bigger, store it.
That is all that has to be done on the relay side, and therefore the only part needed for interoperability.
On the client side, these HLL values received from different relays can be merged (by simply going through all the registers in HLL values from each relay and picking the highest value for each register, regardless of the relay).
And finally the absolute count can be estimated by running some methods I don't dare to describe here in English, it's better to check some implementation source code (also, there can be different ways of performing the estimation, with different quirks applied on top of the raw registers).
### Filter eligibility and `offset` computation
This NIP defines (for now) two filters eligible for HyperLogLog:
- `{"#e": ["<id>"], "kinds": [7]}`, i.e. a filter for `kind:7` events with a single `"e"` tag, which means the client is interested in knowing how many people have reacted to the target event `<id>`. In this case the `offset` will be given by reading the character at the position `32` of the hex `<id>` value as a base-16 number then adding `8` to it.
- `{"#e": ["<id>"], "kinds": [6]}`, the same as above, but for `kind:6` reposts.
- `{"#p": ["<pubkey>"], "kinds": [3]}`, i.e. a filter for `kind:3` events with a single `"p"` tag, which means the client is interested in knowing how many people "follow" the target `<pubkey>`. In this case the `offset` will be given by reading the character at the position `32` of the hex `<pubkey>` value as a base-16 number then adding `8` to it.
- `{"#E": ["<id>"], "kinds": [1111]}`, i.e. a filter for the total number of comments any specific root event has received. In this case the `offset` will be given by reading the character at the position `32` of the hex `<id>` value as a base-16 number then adding `8` to it.
### Attack vectors
One could mine a pubkey with a certain number of zero bits in the exact place where the HLL algorithm described above would look for them in order to artificially make its reaction or follow "count more" than others. For this to work a different pubkey would have to be created for each different target (event id, followed profile etc). This approach is not very different than creating tons of new pubkeys and using them all to send likes or follow someone in order to inflate their number of followers. The solution is the same in both cases: clients should not fetch these reaction counts from open relays that accept everything, they should base their counts on relays that perform some form of filtering that makes it more likely that only real humans are able to publish there and not bots or artificially-generated pubkeys.
### `hll` encoding
The value `hll` value must be the concatenation of the 256 registers, each being a uint8 value (i.e. a byte). Therefore `hll` will be a 512-character hex string.
### Client-side usage
This algorithm also allows clients to combine HLL responses received from relays with HLL counts computed locally from raw events. It's recommended that clients keep track of HLL values locally and add to these on each message received from relays. For example:
- a client wants to keep track of the number of reactions an event Z has received over time;
- the client has decided it will read reactions from relays A, B and C (the NIP-65 "read" relays of Z's author);
- of these, only B and C support HLL responses, so the client fetches both and merges them locally;
- then the client fetches all reaction events from A then manually applies each event to the HLL from the previous step, using the same algorithm described above;
- finally, the client reads the estimate count from the HLL and displays that to the user;
- optionally the client may store that HLL value (together with some "last-read-date" for relay A) and repeat the process again later:
- this time it only needs to fetch the new reactions from A and add those to the HLL
- and redownload the HLL values from B and C and just reapply them to the local value.
This procedure allows the client to download much less data.

@@ -28,16 +28,18 @@ Articles are identified by lowercase, normalized ascii `d` tags.
## Content
The `content` should be Asciidoc with two extra functionalities: **wikilinks** and **nostr:...** links.
The `content` should be [Djot](https://djot.net/) with two special functionalities:
Unlike normal Asciidoc links `http://example.com[]` that link to external webpages, wikilinks `[[]]` link to other articles in the wiki. In this case, the wiki is the entirety of Nostr. Clicking on a wikilink should cause the client to ask relays for events with `d` tags equal to the target of that wikilink.
1. Links can have target URIs in NIP-21 format, like `[bob](nostr:npub1bob4npub4here4qwxek)`.
2. When a reference can't be found for a "Reference"-style link should link to the wiki article with that name instead, like a "wikilink". For example:
Wikilinks can take these two forms:
> a tree is a [vegetable][] that grows big.
>
> trees are often [green][green color], but they can also be [red][red color] as [bob][] says.
>
> [bob]: nostr:npub1bob4npub4here4qwxek
1. `[[Target Page]]` -- in this case it will link to the page `target-page` (according to `d` tag normalization rules above) and be displayed as `Target Page`;
2. `[[target page|see this]]` -- in this case it will link to the page `target-page`, but will be displayed as `see this`.
`nostr:...` links, as per [NIP-21](21.md), should link to profiles or arbitrary Nostr events. Although it is not recommended to link to specific versions of articles -- instead the _wikilink_ syntax should be preferred, since it should be left to the reader and their client to decide what version of any given article they want to read.
In the article above, "vegetable" will link to the wiki article **"vegetable"** (with a `d` tag set to `"vegetable"`), "green" will link to the article **green color** (with `d` set to `"green-color"`), same for "red". But "bob" will link to the specified npub as in the reference.
## Optional extra tags
@@ -87,11 +89,11 @@ This is a stronger signal of trust than a `+` reaction.
This marker is useful when a user edits someone else's entry; if the original author includes the editor's changes and the editor doesn't want to keep/maintain an independent version, the `link` tag could effectively be a considered a "deletion" of the editor's version and putting that pubkey's WoT weight behind the original author's version.
## Why Asciidoc?
## Why Djot?
Wikitext is [garbage](nostr:nevent1qqsqt0gcggry60n72uglhuhypdlmr2dm6swjj69jex5v530gcpazlzsprpmhxue69uhhyetvv9ujumn0wdmksetjv5hxxmmdqy28wumn8ghj7un9d3shjtnyv9kh2uewd9hsygpm7rrrljungc6q0tuh5hj7ue863q73qlheu4vywtzwhx42a7j9n5ueneex) and Markdown is not powerful enough (besides being too freeform and unspecified and prone to generate incompatibilities in the future).
Wikitext is unimplementable. Markdown and Asciidoc do not have strict specs. In Markdown every implementation has its own set of special functionalities that would cause conflict and protocol bloat, also it lacks standardized features that are good to have on encyclopaedias: subscript, superscript, description lists, math, comments and custom labeled blocks. Asciidoc, on the other hand, has all features under the sun, but its spec is so huge no one has ever implemented it, not even in JavaScript (the canonical JavaScript library that most people use is transpiled from the original in Ruby).
Asciidoc has a strict spec, multiple implementations in many languages, and support for features that are very much necessary in a wiki article, like _sidebars_, _tables_ (with rich markup inside cells), many levels of _headings_, _footnotes_, _superscript_ and _subscript_ markup and _description lists_. It is also arguably easier to read in its plaintext format than Markdown (and certainly much better than Wikitext).
Djot is a much faster parser, made by John MacFarlane (the guy behind Pandoc) with years of experience and lessons learned behind him. The spec is well-defined and simple, and has all the features listed above, while also being basically the same as the most basic Markdown.

When adding expiration tags to both `seal` and `gift wrap` layers, implementations SHOULD use independent random timestamps for each layer. Using different `created_at` values increases timing variance and helps protect against metadata correlation attacks.
