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 008/314] 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.

The client MUST send a GET request to this url and parse the response. If `allowsNostr` exists and it is `true`, and if `nostrPubkey` exists and is a valid BIP 340 public key in hex, the client should associate this information with the user, along with the response's `callback`, `minSendable`, and `maxSendable` values. +2. Clients may choose to display a lightning zap button on each post or on a user's profile. If the user's lnurl pay request endpoint supports nostr, the client SHOULD use this NIP to request a zap receipt rather than a normal lnurl invoice. +3. When a user (the "sender") indicates they want to send a zap to another user (the "recipient"), the client should create a `zap request` event as described in Appendix A of this NIP and sign it. +4. Instead of publishing the `zap request`, the `9734` event should instead be sent to the `callback` url received from the lnurl pay endpoint for the recipient using a GET request. See Appendix B for details and an example. +5. The recipient's lnurl server will receive this request and validate it. See Appendix C for details on how to properly configure an lnurl server to support zaps, and Appendix D for details on how to validate the `nostr` query parameter. +6. If the request is valid, the server should fetch a description hash invoice where the description is this note and this note only. No additional lnurl metadata is included in the description. This will be returned in the response according to [LUD06](https://github.com/lnurl/luds/blob/luds/06.md). +7. On receiving the invoice, the client MAY pay it or pass it to an app that can pay the invoice. +8. Once the invoice is paid, the recipient's lnurl server MUST generate a `zap receipt` as described in Appendix E, and publish it to the `relays` specified in the `zap request`. +9. Clients MAY fetch zap notes on posts and profiles, but MUST authorize their validity as described in Appendix F. If the zap request note contains a non-empty `content`, it may display a zap comment. Generally clients should show users the `zap request` note, and use the `zap note` to show "zap authorized by ..." but this is optional. -1. Calculate the lnurl pay request url for a user from the lud06 or lud16 field on their profile +## Reference and examples -2. Fetch the lnurl pay request static endpoint (`https://host.com/.well-known/lnurlp/user`) and gather the `allowsNostr` and `nostrPubkey` fields. If `allowsNostr` exists and it is `true`, and if `nostrPubkey` exists and is a valid BIP 340 public key in hex, associate this information with the user. The `nostrPubkey` is the `zapper`'s pubkey, and it is used to authorize zaps sent to that user. +### Appendix A: Zap Request Event -3. Clients may choose to display a lightning zap button on each post or on the users profile, if the user's lnurl pay request endpoint supports nostr, the client SHOULD generate a `zap invoice` instead of a normal lnurl invoice. +A `zap request` is an event of kind `9734` that is _not_ published to relays, but is instead sent to a recipient's lnurl pay `callback` url. This event's `content` MAY be an optional message to send along with the payment. The event MUST include the following tags: -4. 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. Note that relays should not be nested in an additional list, but should be included as shown in the example below. +- `amount` is the amount in _millisats_ the sender intends to pay, formatted as a string. This is recommended, but optional. +- `lnurl` is the lnurl pay url of the recipient, encoded using bech32 with the prefix `lnurl`. This is recommended, but optional. +- `p` is the hex-encoded pubkey of the recipient. -5. Pay this invoice or pass it to an app that can pay the invoice. Once it's paid, a `zap note` will be created by the `zapper`. +In addition, the event MAY include the following tags: -### LNURL Server side +- `e` is an optional hex-encoded event id.

Add a `nostrPubkey` to the lnurl-pay static endpoint `/.well-known/lnurlp/user`, where `nostrPubkey` is the nostr pubkey of the `zapper`, the entity that creates zap notes. Clients will use this to authorize zaps. - +1. Add a `nostrPubkey` to the lnurl-pay static endpoint `/.well-known/lnurlp/`, where `nostrPubkey` is the nostr pubkey your server will use to sign `zap receipt` events. Clients will use this to validate zap receipts. 2. Add an `allowsNostr` field and set it to true. -3. In the lnurl-pay callback URL, watch for a `nostr` querystring, where the contents of the note is a uri-encoded `zap request` JSON. +### Appendix D: LNURL Server Zap Request Validation -4. If present, the zap request note must be validated: +When a client sends a zap request event to a server's lnurl-pay callback URL, there will be a `nostr` query parameter where the contents of the event are URI- and JSON-encoded. If present, the zap request event must be validated in the following ways: - a. It MUST have a valid nostr signature +1. It MUST have a valid nostr signature +2. It MUST have tags +3. It MUST have only one `p` tag +4. It MUST have 0 or 1 `e` tags +5. There should be a `relays` tag with the relays to send the `zap` note to. +6. If there is an `amount` tag, it MUST be equal to the `amount` query parameter. +7. If there is an `a` tag, it MUST be a valid NIP-33 event coordinate - b.

This needs to be saved somewhere during the generation of the description hash invoice. It is saved automatically for you with CLN, which is the reference implementation used here. +2. Parse the bolt11 description as a JSON nostr event. This SHOULD be validated based on the requirements in Appendix D, either when it is received, or before the invoice is paid. +3.

Client calculates a recipient's lnurl pay request url from the `zap` tag on the event being zapped (see Appendix G), or by decoding their lud06 or lud16 field on their profile according to the [lnurl specifications](https://github.com/lnurl/luds). The client MUST send a GET request to this url and parse the response. If `allowsNostr` exists and it is `true`, and if `nostrPubkey` exists and is a valid BIP 340 public key in hex, the client should associate this information with the user, along with the response's `callback`, `minSendable`, and `maxSendable` values. -2.

Clients may choose to display a lightning zap button on each post or on a user's profile. If the user's lnurl pay request endpoint supports nostr, the client SHOULD use this NIP to request a `zap receipt` rather than a normal lnurl invoice. 3. When a user (the "sender") indicates they want to send a zap to another user (the "recipient"), the client should create a `zap request` event as described in Appendix A of this NIP and sign it. 4. Instead of publishing the `zap request`, the `9734` event should instead be sent to the `callback` url received from the lnurl pay endpoint for the recipient using a GET request. See Appendix B for details and an example. -5. The recipient's lnurl server will receive this request and validate it.

That also makes relays more lightweight, of course. And if some application or user is abusing single-letter tags with the intention of bloating relays that becomes easier to detect as single-letter tags will hardly be confused with some actually meaningful metadata some application really wanted to attach to the event with no spammy intentions. - -Suggested Use Cases -------------------- - -Motivating examples for generic tag queries are provided below. This NIP does not promote or standardize the use of any specific tag for any purpose. - -* Decentralized Commenting System: clients can comment on arbitrary web pages, and easily search for other comments, by using a `r` ("reference", in this case an URL) tag and value. -* Location-specific Posts: clients can use a `g` ("geohash") tag to associate a post with a physical location. Clients can search for a set of geohashes of varying precisions near them to find local content. -* Hashtags: clients can use simple `t` ("hashtag") tags to associate an event with an easily searchable topic name.
