If ### Version ### The relay MAY choose to publish its software version as a string attribute. The string format is defined by the relay implementation.

Your client +should expect that requests which exceed these *practical* limitations +are rejected or fail immediately. + +```json +{ +... + limitation: { + max_message_length: 16384, + max_subscriptions: 20, + max_filters: 100, + max_limit: 5000, + max_subid_length: 100, + min_prefix: 4, + max_event_tags: 100, + max_content_length: 8196, + min_pow_difficulty: 30, + auth_required: true, + payment_required: true, + } +... +} +``` + +- `max_message_length`: this is the maximum number of bytes for incoming JSON that the relay +will attempt to decode and act upon. When you send large subscriptions, you will be +limited by this value. It also effectively limits the maximum size of any event. Value is +calculated from `[` to `]` and is after UTF-8 serialization (so some unicode characters +will cost 2-3 bytes). It is equal to the maximum size of the WebSocket message frame. + +- `max_subscriptions`: total number of subscriptions that may be +active on a single websocket connection to this relay. It's possible +that authenticated clients with a (paid) relationship to the relay +may have higher limits. + +- `max_filters`: maximum number of filter values in each subscription. +Must be one or higher. + +- `max_subid_length`: maximum length of subscription id as a string. + +- `min_prefix`: for `authors` and `ids` filters which are to match against +a hex prefix, you must provide at least this many hex digits in the prefix. + +- `max_limit`: the relay server will clamp each filter's `limit` value to this number. +This means the client won't be able to get more than this number +of events from a single subscription filter. This clamping is typically done silently +by the relay, but with this number, you can know that there are additional results +if you narrowed your filter's time range or other parameters. + +- `max_event_tags`: in any event, this is the maximum number of elements in the `tags` list. + +- `max_content_length`: maximum number of characters in the `content` +field of any event. This is a count of unicode characters. After +serializing into JSON it may be larger (in bytes), and is still +subject to the `max_message_length`, if defined. + +- `min_pow_difficulty`: new events will require at least this difficulty of PoW, +based on [NIP-13](13.md), or they will be rejected by this server. + +- `auth_required`: this relay requires [NIP-42](42.md) authentication +to happen before a new connection may perform any other action. +Even if set to False, authentication may be required for specific actions. + +- `payment_required`: this relay requires payment before a new connection may perform any action. + +### Event Retention ### + +There may be a cost associated with storing data forever, so relays +may wish to state retention times. The values stated here are defaults +for unauthenticated users and visitors. Paid users would likely have +other policies. + +Retention times are given in seconds, with `null` indicating infinity. +If zero is provided, this means the event will not be stored at +all, and preferably an error will be provided when those are received. + +```json +{ +... + retention: [ + { kinds: [0, 1, [5, 7], [40, 49]], time: 3600 }, + { kinds: [[40000, 49999], time: 100 }, + { kinds: [[30000, 39999], count: 1000 }, + { time: 3600, count: 10000 } + ] +... +} +``` + +`retention` is a list of specifications: each will apply to either all kinds, or +a subset of kinds. Ranges may be specified for the kind field as a tuple of inclusive +start and end values. Events of indicated kind (or all) are then limited to a `count` +and or time period. + +It is possible to effectively blacklist Nostr-based protocols that rely on +a specific `kind` number, by giving a retention time of zero for those `kind` values. +While that is unfortunate, it does allow clients to discover servers that will +support their protocol quickly via a single HTTP fetch. + +There is no need to specify retention times for _ephemeral events_ as defined +in [NIP-16](16.md) since they are not retained. + + +### Content Limitations ### + +Some relays may be governed by the arbitrary laws of a nation state. This +may limit what content can be stored in cleartext on those relays. All +clients are encouraged to use encryption to work around this limitation. + +It is not possible to describe the limitations of each country's laws +and policies which themselves are typically vague and constantly shifting. + +Therefore, this field allows the relay operator to indicate which +country's' laws might end up being enforced on them, and then +indirectly on their users's content. + +Users should be able to avoid relays in countries they don't like, +and/or select relays in more favourable zones. Exposing this +flexibility is up to the client software. + +```json +{ +... + relay_countries: [ 'CA', 'US' ], +... +} +``` + +- `relay_countries`: a list of two-level ISO country codes (ISO 3166-1 alpha-2) whose + laws and policies may affect this relay. `EU` may be used for European Union countries. + +Remember that a relay may be hosted in a country which is not the +country of the legal entities who own the relay, so it's very +likely a number of countries are involved. + + +### Community Preferences ### + +For public text notes at least, a relay may try to foster a +local community. This would encourage users to follow the global +feed on that relay, in addition to their usual individual follows. +To support this goal, relays MAY specify some of the following values. + +```json +{ +... + language_tags: [ 'en', 'en-419' ], + tags: [ 'sfw-only', 'bitcoin-only', 'anime' ], + posting_policy: 'https://example.com/posting-policy.html', +... +} +``` + +- `language_tags` is an ordered list + of [IETF language tags](https://en.wikipedia.org/wiki/IETF_language_tag) indicating + the major languages spoken on the relay. + +- `tags` is a list of limitations on the topics to be discussed. + For example `sfw-only` indicates hat only "Safe For Work" content + is encouraged on this relay. This relies on assumptions of what the + "work" "community" feels "safe" talking about. In time, a common + set of tags may emerge that allow users to find relays that suit + their needs, and client software will be able to parse these tags easily. + The `bitcoin-only` tag indicates that any *altcoin*, *"crypto"* or *blockchain* + comments will be ridiculed without mercy. + +- `posting_policy` is a link to a human-readable page which specifies the + community policies for the relay. In cases where `sfw-only` is True, it's + important to link to a page which gets into the specifics of your posting policy. + +The `description` field should be used to describe your community +goals and values, in brief. The `posting_policy` is for additional +detail and legal terms. Use the `tags` field to signify limitations +on content, or topics to be discussed, which could be machine +processed by appropriate client software. + +### Pay-To-Relay ### + +Relays that require payments may want to expose their fee schedules. + +```json +{ +... + payments_url: "https://my-relay/payments", + fees: { + "admission": [{ amount: 1000000, unit: 'msats' }], + "subscription": [{ amount: 5000000, unit: 'msats', period: 2592000 }], + "publication": [{ kinds: [4], amount: 100, unit: 'msats' }], + }, +... +} From 92a41a284a55371e13f7155be0ba8a9ab4225561 Mon Sep 17 00:00:00 2001 From: nostr-wine <124309146+nostr-wine@users.noreply.github.com> Date: Sat, 18 Mar 2023 18:53:54 -0400 Subject: [PATCH 26/50] Add doc-hex as author --- 11.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/11.md b/11.md index a8386ba3..c5383262 100644 --- a/11.md +++ b/11.md @@ -4,7 +4,7 @@ NIP-11 Relay Information Document --------------------------- -`draft` `optional` `author:scsibug` +`draft` `optional` `author:scsibug` `author:doc-hex` Relays may provide server metadata to clients to inform them of capabilities, administrative contacts, and various server attributes.

There could be clients that do not support autocomplete at all, so they just allow users to paste raw [NIP-19](19.md) codes into the body of text, then prefix these with `nostr:` before publishing the event. +- The flow for referencing other events is similar: a user could paste a `note1...` or `nevent1...` code and the client will turn that into a `nostr:note1...` or `nostr:nevent1...` URL. Then upon reading such references the client may show the referenced note in a preview box or something like that -- or nothing at all. +- Other display procedures can be employed: for example, if a client that is designed for dealing with only `kind:1` text notes sees, for example, a [`kind:30023`](23.md) `nostr:naddr1...` URL reference in the `.content`, it can, for example, decide to turn that into a link to some hardcoded webapp capable of displaying such events. +- Clients may give the user the option to include or not include tags for mentioned events or profiles. If someone wants to mention `mattn` without notifying them, but still have a nice augmentable/clickable link to their profile inside their note, they can instruct their client to _not_ create a `["p", ...]` tag for that specific mention. +- In the same way, if someone wants to reference another note but their reference is not meant to show up along other replies to that same note, their client can choose to not include a corresponding `["e", ...]` tag for any given `nostr:nevent1...` URL inside `.content`. Clients may decide to expose these advanced functionalities to users or be more opinionated about things.

To generate a `zap invoice`, call the `callback` url with `amount` set to the milli-satoshi amount value. A `nostr` querystring value MUST be set as well. It is a uri-encoded `zap request` note signed by the user's key. The `zap request` note contains an `e` tag of the note it is zapping, and a `p` tag of the target user's pubkey. The `e` tag is optional which allows profile tipping. An optional `a` tag allows tipping parameterized replaceable events such as NIP-23 long-form notes. The `zap request` note must also have a `relays` tag, which is gathered from the user's configured relays. The `zap request` note SHOULD contain an `amount` tag, which is the milli-satoshi value of the zap which clients SHOULD verify being equal to the amount of the invoice. The `content` MAY be an additional comment from the user which can be displayed when listing zaps on posts and profiles. +- `relays` is a list of relays the recipient's wallet should publish its `zap receipt` to.
