|
||||
## Table of Kinds
|
||||
This NIP defines three (3) event kinds, `30066`, `30166` and `10166`
|
||||
You want to find relays. You may want to discover relays based on criteria that's up to date. You may even want to ensure that you have a complete dataset. You probably want to filter relays based on their reported liveness.
|
||||
|
||||
In its purest form:
|
||||
```json
|
||||
{
|
||||
"sig": "<signature>",
|
||||
"pubkey": "<pubkey>",
|
||||
"id": "<eventid>",
|
||||
"content": "{}",
|
||||
"created_at": 1722173222,
|
||||
"kind": 30166,
|
||||
"tags": [

"d",
|
||||
"wss://eostagram.com/"
|
||||
]
|
||||
]
|
||||
}
|
||||
```
|
||||
This event signals that the relay at `wss://eostagram.com/` was reported "online" by `<pubkey>` at timestamp `1722173222`. This event **MAY** be extended upon to include more information.
|
||||
|
||||
|
||||
## Kinds
|
||||
This NIP defines two (2) event kinds, `10166` and `30166`

| [30166](#k30166) | Relay Discoverability | A PRE composed of only indexed tags used to discover relays [`d`] |
|
||||
| [30066](#k30066) | Relay Metadata | A PRE composed of human readable, non-indexed tags used to find data on a relay [`d`] |
|
||||
|
||||
## High Level
|
||||
nostr is a network composed of dumb relays that exhibit different behaviors that are mostly, but not entirely self-reported by their NIP-11 document. However, discoverabililty of relays, and acquiring metadata for relays at the protocol level is not presently implemented. Additionally, self-reported data has an extremely low cieling and is not always reliable.
|
||||
|
||||
## History
|
||||
- `draft1` implemented in `January 2023` and proposed `February 2023`. "Too many one-letter indexable tags"
|
||||
- `draft2` experimented with `March 2023` "Everything should be expirable"
|
||||
- `draft3` experimented, never proposed
|
||||
- `draft4` experimented, never proposed
|
||||
- `draft5` proposed `December 2023`, "Needs to be indexed"
|
||||
- `draft6` proposed `February 2024`, "Just use one-letter indexable tags" (lol) and split discoverability and parse cases.
|
||||
|
||||
|
||||
## Status
|
||||
Starting in `NIP-66@draft6` **Relay Metadata** and **Relay Discoverability** are considered as two different cases and are split into two different events. However, there remains a pattern for monitors to flag that their `30066` events are indexable.
|
||||
| [10166](#k10166) | Relay Monitor Announcement | An RE that stores data to publish intent to monitor and details around their activities |
|
||||
| [30166](#k30166) | Relay Discovery | A PRE that is published by a monitor when a relay is online |
|
||||

### Summary
|

`10166` is a replacable event herein referred to as "Relay Monitor Registration" events. These events contain information about a publisher's intent to monitor and publish data as `NIP-66` events.
|
||||
`10166` is a replacable event herein referred to as "Relay Monitor Announcement" events. These events contain information about a publisher's intent to monitor and publish data as `NIP-66` events.
|
||||
|
||||
### Purpose
|
||||
To provide a directory of monitors, their intent to publish, their criteria and parameters of monitoring activities.
|
||||
|
||||
|
||||
### Kind Usage
|
||||
`NIP-66` kinds can be used by both "Relay Operators" and "Relay Monitors," with the exception that "Relay Operators" **SHOULD NOT** use `10166`
|
||||
|
||||
| Kind | Monitors | Operators |
|
||||
|-------|----------|-----------|
|
||||
| `10166` | x | |
|
||||
| `30066` | x | x |
|
||||
| `30166` | x | x |
|
||||
To provide a directory of monitors, their intent to publish, their criteria and parameters of monitoring activities. Absence of the `10166` event is not encouraged, but if absent implies the monitor is ad-hoc and does not publish events at a predictable frequency.
|
||||
|
||||
### Schema
|
||||
|
||||
#### Summary
|
||||
|
||||
#### Non-Indexed Tags
|
||||
|
||||
- `url` A URL with human readable information about the monitor's activities. If not included, it is assumed these details are included in the monitor's `website` member in their `kind: 0` JSON for the pubkey that signed the `10066` event.
|
||||
|
||||
- `timeout` The timeout values for various tests. Index `1` is the monitor's timeout in milliseconds. Index `2` describes what test the timeout is used for, for example `open`, `read`, `write`, `info`, etc. If no index `2` is provided, it is inferred that the timeout provided applies to all tests.
|
||||
```json
|
||||
[ "timeout", "open", "2000" ],
|
||||
[ "timeout", "read", "2000" ],
|
||||
[ "timeout", "write", "3000" ],
|
||||
[ "timeout", "nip11", "2000" ],
|
||||
[ "timeout", "ssl", "4000" ]
|
||||
```
|
||||
|
||||
- `frequency` The frequency at which the monitor publishes events. A string-integer at index `1` represents the frequency **in seconds** of the checks. There should only be `1` frequency per monitor.
|
||||
- `frequency` The frequency **in seconds** at which the monitor publishes events. A string-integer at index `1` represents the expected frequency the monitor will publish `30166` events. There should only be `1` frequency per monitor. A `-1` frequency means that the monitor does not publish events at a predictable frequency.
|
||||
|
||||
```json
|
||||
[ "frequency", "3600" ]
|
||||
```
|
||||
|
||||
- `timeout` (optional) The timeout values for various checks conducted by a monitor. Index `1` is the monitor's timeout in milliseconds. Index `2` describes what test the timeout is used for, for example `open`, `read`, `write`, `nip11`, etc. If no index `2` is provided, it is inferred that the timeout provided applies to all tests. These values can assist relay operators in understanding data signaled by the monitor in _Relay Discovery Events_.
|
||||
```json
|
||||
[ "timeout", "2000", "open" ],
|
||||
[ "timeout", "2000", "read" ],
|
||||
[ "timeout", "3000", "write" ],
|
||||
[ "timeout", "2000", "nip11" ],
|
||||
[ "timeout", "4000", "ssl" ]
|
||||
```
|
||||
|
||||
#### Indexed Tags
|
||||
- `k` "Kinds" **should** be a the string-representation of an integer that describes the NIP-66 kinds this monitor publishes. _Note: Kind `10166` **does not** need to be listed here._
|
||||
- `c` "Checks" **SHOULD** be a lowercase string describing the check(s) conducted by a monitor. Some examples are: `ws`, `nip11`, `ssl`, `dns`, `geo`, etc. Other checks **MAY** be included. New types of checks **SHOULD** be added to this NIP as they are needed.
|
||||
```json
|
||||
[ "k", "30066" ],
|
||||
[ "k", "30166" ]
|
||||
```
|
||||
|
||||
While `30066` and `30166` have a high-level separation of concerns by Metadata and Discoverability, a monitor can decide to flag `30066` as indexable, and include indexed tags defined in `30166` within their `30066` Relay Metadata events.
|
||||
|
||||
```json
|
||||
[ "k", "30066", "indexed"],
|
||||
```
|
||||
|
||||
- `c` "Checks" **should** be a lowercase string describing the check(s) conducted by a monitor. Some examples are: `rtt`, `nip11`, `ssl`, `dns`, `geo` and `count`. Other checks can be added via consensus.
|
||||
|
||||
```json
|
||||
[ "c", "rtt" ],
|
||||
[ "c", "ws" ],
|
||||
[ "c", "nip11" ],
|
||||
[ "c", "dns" ],
|
||||
[ "c", "geo" ],
|
||||
[ "c", "dns" ],
|
||||
[ "c", "count" ]
|
||||
[ "c", "ssl" ],
|
||||
```
|
||||
|
||||
- `n` "Counts" **should** be a lower-snake-case string describing the counts(s) conducted by a monitor at index `1`. Some examples are: `total_active_users`, `total_note_zaps`, `total_note_reactions`, `events_per_minute`, `note_publish_rate`. Counts are not atomized, their values are entirely ad-hoc. The time period of the count is defined in `30066`
|
||||
|
||||
- `g`: `NIP-52` `g` tags (geohash)
|
||||
```json
|
||||
[ "n", "users_total_active" ],
|
||||
[ "n", "note_total_zaps" ],
|
||||
[ "n", "note_total_reactions" ],
|
||||
[ "n", "note_publish_rate" ]
|
||||
```
|
||||
|
||||
- `o` The hex pubkey of the owner of the monitor. A "Monitor Service" will likely run several monitors.
|
||||
```json
|
||||
[ "o", "b3b0d247f66bf40c4c9f4ce721abfe1fd3b7529fbc1ea5e64d5f0f8df3a4b6e6" ]
|
||||
```
|
||||
|
||||
- `g`: `NIP-66` leverages a draft NIP for geo tags, which is backwards compatible with `0` collisions for legacy `g` tags from `NIP-52`. See [YAGT](https://github.com/nostr-protocol/nips/pull/952)
|
||||

```
|

Monitors **should** have the following
|

### Summary
|
||||
`30166` is a `NIP-33` Parameterized-Replaceable Event [PRE], referred to as a "Relay Discoverability" event. These events are optimized with a small footprint for protocol-level relay discoverability, and contain no unindexed tags.
|
||||
`30166` is a `NIP-33` Parameterized-Replaceable Event [PRE], referred to as a "Relay Discovery" event. These events are optimized with a small footprint for protocol-level relay Discovery.
|
||||
|
||||
### Purpose
|
||||
Enables protocol-level discovery of relays on a variety of parameters while ommitting the large footprint of metadata in the "Discovery Case"
|
||||
Enables the discovery of relays via nostr protocol.
|
||||
|
||||
### Schema
|
||||
|
||||
#### Summary
|
||||
`30166` events contain only indexable tags.
|
||||
#### Content
|
||||
`30166` content fields **MAY** include the stringified JSON of the relay's NIP-11 informational document. This data **MAY** be provided for informational purposes only.
|
||||
|
||||
#### Indexed Tags
|
||||
#### `created_at`
|
||||
The `created_at` field in a NIP-66 event should reflect the time when the relay liveness (and potentially other data points) was checked.
|
||||
|
||||
#### `tags`
|
||||
|
||||
##### Meta Tags (unindexed)
|
||||
- `rtt-open` The relay's open **round-trip time** in milliseconds.
|
||||
- `rtt-read` The relay's read **round-trip time** in milliseconds.
|
||||
- `rtt-write` The relay's write **round-trip time** in milliseconds.
|
||||
|
||||
_Other `rtt` values **MAY** be present. This NIP should be updated if there is value found in more `rtt` values._
|
||||
|
||||
##### Single Letter Tags (indexed)
|
||||
- `d` The relay URL. The `#d` tag **must** be included in the `event.tags[]` array. Index position `1` **must** be the relay websocket URL. The URL **SHOULD** be [normalized](https://datatracker.ietf.org/doc/html/rfc3986#section-6)

##### Important Notes
|
||||
- Relay Monitors that publish `30166` events **SHOULD** at a minimum be conducting `rtt` checks, namely websocket `open`, so that clients can determine liveness.
|
||||
- `k` indexable tags are not associated to any other standard and thus cannot be flagged for support in `10166` until `NIP-11` support kind flagging.
|

|
||||
## `30066`: "Relay Metadata" <a id="k30066"></a>
|
||||
|
||||
### Summary
|
||||
`30066` is a `NIP-33` Parameterized-Replaceable Event [PRE], referred to as a "Relay Metadata" event. These events store the existence and optionally some data relating to the relay. These events can be published by a monitor or self published by relay operators
|
||||
|
||||
### Purpose
|
||||
To store useful, computationally expensive data derived from checks and other metadata about relays. This data is found by filtering the normalized relay URL with the `d` tag. Determining liveness `30066` can be used by filtering against `since` with respect to the `frequency` value set in a **Relay Monitor's** `10166` event kind.
|
||||
|
||||
### Schema
|
||||
|
||||
#### `event.content`
|
||||
`content` **MAY** contain stringified `NIP-11` JSON, since the `NIP-11` cannot be serialized into tags with any sane patterns.
|
||||
|
||||
#### `event.tags`
|
||||
|
||||
##### Summary
|
||||
1. "Relay Metadata" events have **one** (1) required tag
|
||||
2. **Unindexed Tags** use grouping by defining the _group_ at index position `1`, the key at index position `2` and the value at index position `3`.
|
||||
|
||||
#### Indexed Tags
|
||||
- `d` The relay URL. The `#d` tag **MUST** be included in the `event.tags[]` array. Index position `1` **SHOULD** be the relay websocket URL. The URL **SHOULD** be [normalized](https://datatracker.ietf.org/doc/html/rfc3986#section-6)
|
||||
```json
|
||||
[ "d", "wss://history.nostr.watch/"]
|
||||
```
|
||||
- `30066` events **MAY** contain any of the indexable tags included in `30166` kind events (See instructions for this case in `10166`'s schema, specifically under `k`)
|
||||
#### Unindexed Tags
|
||||
- `rtt` group contains key/value pairs that describe the round trip time of a particular operation. Values at position `2...` **SHOULD** treated as an array by consumers. This array can be used to **mathematically** find `min`, `max`, `average` and `median` values. For example `Math.min(...["190", "201", "540"].map( n => parseInt(n) ))`. Some obvious index `1` keys are websocket `open`, `read` and `write` round-trip times, as well as `nip11` https request round-trip time.
|
||||
```json
|
||||
["rtt", "open", "190", "201", "540"],
|
||||
["rtt", "read", "35"],
|
||||
["rtt", "write", "701"]
|
||||
```
|
||||
|
||||
- `ssl` group contains key/value pairs that describe the checked status of a relay's SSL Certificate. Index `1` keys for `ssl` can be atomized and should be one of the following `valid_from`, `valid_to`, `subject_alt_name`, `fingerprint`, `fingerprint256`, `fingerprint512`, `ext_key_usage`, `exponent`, `serial_number`, `modulus` and/or `pem_encoded`. There **SHOULD NOT** be duplicate keys.
|
||||
```json
|
||||
["ssl", "valid_from", "<timestamp_seconds>"],
|
||||
["ssl", "valid_to", "<timestamp_seconds>"]
|
||||
```
|
||||
|
||||
- `dns` group contains key/value pairs that describe a DNS lookup for the relay from the perspective of a given monitor. It can provide insights on other meta data in the event. Index `1` keys for `dns` can be atomized and should be one of the following `as`, `asn`, `ipv4` or `ipv6`. There **MAY** be duplicate keys.
|
||||
```json
|
||||
["dns", "asn", "19281"],
|
||||
["dns", "as", "QUAD9-AS-1, CH"],
|
||||
["dns", "ipv4", "1.1.1.1"],
|
||||
["dns", "ipv6", "2001:db8:3333:4444:5555:6666:7777:8888"]
|
||||
```
|
||||
|
||||
- `nip11` group is a special group that extracts specific values as long as they are no more than 1 level deep and do not contain arrays of objects. This data **MAY** be duplicated as stringified `NIP-11` JSON in content.
|
||||
```json
|
||||
["nip11", "name", "A nostr relay"],
|
||||
["nip11", "description", "It stores notes and other stuff"],
|
||||
["nip11", "owner", "<pubkey:hex>"],
|
||||
["nip11", "software", "<software>"],
|
||||
["nip11", "version", "<version>"]
|
||||
```
|
||||
For arrays
|
||||
```json
|
||||
["nip11", "supported_nips", "3", "33"],
|
||||
```
|
||||
|
||||
- `count` Meta values for arbitrary counts related to a relay. Index position `1` is the value expressed as the string representation of an integer or float. Index position `2` is the key and describes the count, such as `total_users` or `total_events`. Index position `3` **MAY** be set and defines the "period" in seconds that the count at position `2` was calculated. Counts **SHOULD** only be included when representing unique or computationally expensive counts, not ones that can be easily achieved via `NIP-45` counts. A count's key **SHOULD** be **snake case**. There **MAY** be zero (0) to many count tags.
|
||||
|
||||
```json
|
||||
["count", "users_total_active", "201", "86400"],
|
||||
["count", "note_total_zaps", "87", "86400"],
|
||||
["count", "note_total_reactions", "125", "86400"],
|
||||
["count", "note_publish_rate", "24.1", "3600"]
|
||||
```
|
||||
|
||||
- `other`: A group for other type checks that could be a derivative of another check or unassociated to a specific check. A good example is `network` which is is determined by parsing the URL to attempt to identify which network it can be found on, and would likely already be in the monitor's cache as it was determined for discoverability purposes.
|
||||
```json
|
||||
["other", "network", "clearnet"]
|
||||
```
|
||||
|
||||
#### Tag Usage
|
||||
For self-reported `30066` events by "Relay Operators", certain tags **SHOULD NOT** be self-published or otherwised ignored by clients if present. Please reference the table below.
|
||||
|
||||
| | Monitor | Relay Operators |
|
||||
|----------|---------|-----------------|
|
||||
| rtt | x | |
|
||||
| nip11 | x | x |
|
||||
| dns | x | x |
|
||||
| geo | x | x |
|
||||
| ssl | x | |
|
||||
| count | x | x |
|
||||
| other | x | x |
|
||||
|
||||
#### Methodology
|
||||
A _Relay Monitor_ publishes `30066` events exclusively when a relay is reachable. This approach ensures that the last known active state of the relay is maintained and recorded in `created_at` value of event. Based on this data, several inferences can be drawn about the relay's status and characteristics.
|
||||
|
||||
1. Clients and/or users can set a custom threshold to establish a cutoff timestamp for filtering events using `since`. This timestamp helps in identifying which relays are currently online. Selecting a lower threshold value results in a stricter criterion for relay uptime, making the filter more sensitive to brief downtimes. Conversely, choosing a higher threshold value creates a more lenient filter, allowing relays with longer downtimes to still be considered as online.
|
||||
##### Monitors
|
||||
1. A _Relay Monitor_ checks the liveness of a relay at the `frequency` defined in their `10166`.
|
||||
|
||||
2. In determining whether a relay is 'dead,' the decision is solely at the discretion of the client or user. The are responsible for setting and applying arbitrary thresholds using `until` filters or post-processing to make this determination. This approach underscores that the classification of a relay as 'dead' is a subjective decision, varying according to each client's or user's assessment criteria, rather than a fixed status provided by the monitor.
|
||||
2. _Relay Monitor_ publishes a kind `30166` note when a relay it is monitoring is online.
|
||||
|
||||
3. For [Relay Metadata](#k30066) events that have become outdated, the retained data points remain valuable. They offer insights and information about the relay's characteristics, performance and impact on the network, which might not be currently accessible due to the relay being offline.
|
||||
_Relay Monitors that publish `30166` events **SHOULD** at a minimum be checking that the relay is available by websocket and behaves like a relay_
|
||||
|
||||
#### Important Notes
|
||||
- Relay Monitors **SHOULD** run checks and publish events according to the `frequency` value set in their respective `10166` kind event.
|
||||
- If a relay monitor publishes both `30166` and `30066` kind events, they **SHOULD** publish both on every check.
|
||||
- Clients **SHOULD** only use monitors reporting `rtt` values for websockets (particularly `open`) for determining the "liveness" or "deadness" of a relay.
|
||||
- Clients **SHOULD** consider the `frequency` value in a monitor's `10166` when trying to reach determination of "liveness".
|
||||
- `NIP-11` values are provided as means to filter and discover relays, however ****SHOULD NOT** be used as a replacement to `NIP-11`.
|
||||
- A particular relay's retention policy could conflict with subjective thresholds used in determination of "liveness" or "deadness" of relays and so care **SHOULD** be taken with regards to chosen relays for `NIP-66` by both monitors and consumers.
|
||||
##### Clients
|
||||
1. In most cases, a client **SHOULD** filter on `30166` events using either a staticly or dynamically chosen monitor's `pubkey` and a `created_at` value respective of the monitor's published `frequency`.
|
||||
|
||||
#### Examples
|
||||
2. _Relay Liveness_ is subjectively determined by the client, starting with the `frequency` value of a monitor.
|
||||
|
||||
##### Minimum Requirements
|
||||
_"Relay was online at `<created_at>`"_
|
||||
```json
|
||||
{
|
||||
"id": "<eventid>",
|
||||
"pubkey": "<pubkey>",
|
||||
"created_at": "<created_at>",
|
||||
"signature": "<signature>",
|
||||
"content": "",
|
||||
"kind": 30066,
|
||||
"tags": [
|
||||
["d","wss://some.relay/"]
|
||||
]
|
||||
}
|
||||
```
|
||||
3. The liveness of a _Relay Monitor_ can be subjectively determined by detecting whether the _Relay Monitor_ has published events within the specified `frequency`.
|
||||
|
||||
##### Relay is checked and online
|
||||
_"Relay was online at <created_at> and here's some meta-data this monitor believes is accurate"_
|
||||
```json
|
||||
{
|
||||
"id": "<eventid>",
|
||||
"pubkey": "<monitor's pubkey>",
|
||||
"created_at": "<created_at>",
|
||||
"signature": "<signature>",

|
||||
["count", "note_publish_rate", "24.1", "3600"]
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
#### Testing Criteria
|
||||
The testing criteria to determine conditions defined in event's tags **MAY** be subjective and **MAY** vary between monitors.
|
||||
|
||||
#### Limitations
|
||||
The data in `30066` **MAY** be erroneous, intentionally or otherwise. Where accuracy is required, the data in `30066` events **SHOULD** be subscribed to by populating the `authors` filter array with the public keys of subjectively **trusted monitors** and where security or privacy is a concern any republished values (such as NIP-11 values) should instead be attained from the source (https). All data is for informational purposes and to make finding and filtering through relays through nostr a possiblity.
|
||||
|
||||
## Ammending NIP-66
|
||||
Any test results that cannot be expressed through `NIP-66` **should** be ammended to the nip following discussion and general consensus
