It's advisable that relays do not serve `kind:1059` to clients other than the ones tagged in them. Relays MAY protect message metadata by only serving `kind:1059` events to users p-tagged on the event (enforced using [NIP 42 AUTH](./42.md)).
It's advisable that users choose relays that conform to these practices. Clients SHOULD guide users to keep `kind:10050` lists small (1-3 relays) and SHOULD spread them to as many relays as viable.

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>",

## 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.

## Content ## Content
The `content` should be [Djot](https://djot.net/) with two special functionalities: The `content` should be Asciidoc with two extra functionalities: **wikilinks** and **nostr:...** links.
1. Links can have target URIs in NIP-21 format, like `[bob](nostr:npub1bob4npub4here4qwxek)`. 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.
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:
> a tree is a [vegetable][] that grows big. Wikilinks can take these two forms:
>
> trees are often [green][green color], but they can also be [red][red color] as [bob][] says.
>
> [bob]: nostr:npub1bob4npub4here4qwxek
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. 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.

## Why Djot? ## Why Asciidoc?
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). 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).
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. 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).

NIP-BE
======
Nostr BLE Communications Protocol
---------------------------------
`draft` `optional`
This NIP specifies how Nostr apps can use BLE to communicate and synchronize with each other. The BLE protocol follows a client-server pattern, so this NIP emulates the WS structure in a similar way, but with some adaptations to its limitations.
## Device advertisement
A device advertises itself with:
- Service UUID: `0000180f-0000-1000-8000-00805f9b34fb`
- Data: Device UUID in ByteArray format
## GATT service
The device exposes a Nordic UART Service with the following characteristics:
1. Write Characteristic
- UUID: `87654321-0000-1000-8000-00805f9b34fb`
- Properties: Write
2. Read Characteristic
- UUID: `12345678-0000-1000-8000-00805f9b34fb`
- Properties: Notify, Read
## Role assignment
When one device initially finds another advertising the service, it will read the service's data to get the device UUID and compare it with its own advertised device UUID. For this communication, the device with the highest ID will take the role of GATT Server (Relay), the other will be considered the GATT Client (Client) and will proceed to establish the connection.
For devices whose purpose will require a single role, its device UUID will always be:
- GATT Server: `FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF`
- GATT Client: `00000000-0000-0000-0000-000000000000`
## Messages
All messages will follow [NIP-01](/01.md) message structure. For a given message, a compression stream (DEFLATE) is applied to the message to generate a byte array. Depending on the BLE version, the byte array can be too large for a single message (20-23 bytes in BLE 4.2, 256 bytes in BLE > 4.2). In that case, this byte array is split into any number of batches following the structure:
```
[batch index (first 2 bytes)][batch n][is last batch (last byte)]
```
After reception of all batches, the other device can then join them and decompress. To ensure reliability, only 1 message will be read/written at a time. MTU can be negotiated in advance. The maximum size for a message is 64KB; bigger messages will be rejected.
## Examples
This example implements a function to split and compress a byte array into chunks, as well as another function to join and decompress them in order to obtain the initial result:
```kotlin
fun splitInChunks(message: ByteArray): Array<ByteArray> {
val chunkSize = 500 // define the chunk size
var byteArray = compressByteArray(message)
val numChunks = (byteArray.size + chunkSize - 1) / chunkSize // calculate the number of chunks
var chunkIndex = 0
val chunks = Array(numChunks) { ByteArray(0) }
for (i in 0 until numChunks) {
val start = i * chunkSize
val end = minOf((i + 1) * chunkSize, byteArray.size)
val chunk = byteArray.copyOfRange(start, end)
// add chunk index to the first 2 bytes and last chunk flag to the last byte
val chunkWithIndex = ByteArray(chunk.size + 2)
chunkWithIndex[0] = chunkIndex.toByte() // chunk index
chunk.copyInto(chunkWithIndex, 1)
chunkWithIndex[chunkWithIndex.size - 1] = numChunks.toByte()
// store the chunk in the array
chunks[i] = chunkWithIndex
chunkIndex++
}
return chunks
}
fun joinChunks(chunks: Array<ByteArray>): ByteArray {
val sortedChunks = chunks.sortedBy { it[0] }
var reassembledByteArray = ByteArray(0)
for (chunk in sortedChunks) {
val chunkData = chunk.copyOfRange(1, chunk.size - 1)
reassembledByteArray = reassembledByteArray.copyOf(reassembledByteArray.size + chunkData.size)
chunkData.copyInto(reassembledByteArray, reassembledByteArray.size - chunkData.size)
}
return decompressByteArray(reassembledByteArray)
}
```
## Workflows
### Client to relay
- Any message the client wants to send to a relay will be a write message.
- Any message the client receives from a relay will be a read message.
### Relay to client
The relay should notify the client about any new event matching subscription's filters by using the Notify action of the Read Characteristic. After that, the client can proceed to read messages from the relay.
### Device synchronization
Given the nature of BLE, it is expected that the direct connection between two devices might be extremely intermittent, with gaps of hours or even days. That's why it's crucial to define a synchronization process by following [NIP-77](./77.md) but with an adaptation to the limitations of the technology.
After two devices have successfully connected and established the Client-Server roles, the devices will use half-duplex communication to intermittently send and receive messages.
#### Half-duplex synchronization
Right after the 2 devices connect, the Client starts the workflow by sending the first message.
1. Client - Writes ["NEG-OPEN"](/77.md#initial-message-client-to-relay) message.
2. Server - Sends `write-success`.
3. Client - Sends `read-message`.
4. Server - Responds with ["NEG-MSG"](./77.md#subsequent-messages-bidirectional) message.
5. Client -
1. If the Client has messages missing on the Server, it writes one `EVENT`.
2. If the Client doesn't have any messages missing on the Server, it writes `EOSE`. In this case, subsequent messages to the Server will be empty while the Server claims to have more notes for the Client.
6. Server - Sends `write-success`.
7. Client - Sends `read-message`.
8. Server -
1. If the Server has messages missing on the Client, it responds with one `EVENT`.
2. If the Client doesn't have any messages missing on the Server, it responds with `EOSE`. In this case, subsequent responses to the Client will be empty.
9. If the Client detects that the devices are not synchronized yet, jump to step 5.
10. After the two devices detect that there are no more missing events on both ends, the workflow will pause at this point.
#### Half-duplex event spread
While two devices are connected and synchronized, it might happen that one of them receives a new message from another connected peer. Devices MUST keep track of which notes have been sent to its peers while they are connected. If the newly received event is detected as missing in one of the connected and synchronized peers:
1. If the peer is a Server:
1. Client - It writes the `EVENT`.
2. Server - Sends `write-success`.
2. If the peer is a Client:
1. Server - It will send an empty notification to the Client.
2. Client - Sends `read-message`.
3. Server - Responds with the `EVENT`.
