Specifications about #nip

The window.nostr object a browser extension exposes, letting a web page read a public key and have events signed without ever seeing the private key.

This NIP defines a standard for creating and managing todo lists on Nostr, enabling interoperability between different todo list applications.

Groups whose membership and rules are enforced by the relay hosting them, identified by an id scoped to that relay.

Nostr Wallet Connect, where a client drives a remote Lightning wallet through encrypted events.

Kind 39701, a web bookmark addressed by its own URI, editable by whoever saved it.

Code collaboration on Nostr: repository announcements, repository state, patches, and issues.

A marketplace protocol built from stalls, products and order messages, kept for the clients that implemented it.

Remote signing: a client sends signing requests over an encrypted channel to a signer that holds the key and never surrenders it.

The list kinds, with public entries in the tags and private ones encrypted in the content: mutes, bookmarks, relay sets, follow sets and the rest.

A JSON-RPC API over HTTP for administering a relay: banning keys, allowing kinds, listing what it refuses.

How a relay advertises the roles it grants and the membership it enforces, and how a client asks to be admitted.

The versioned encryption format the rest of Nostr builds on: secp256k1 ECDH, HKDF, padding, ChaCha20 and HMAC-SHA256.

How an application declares the event kinds it can handle, and how users recommend one for a kind their client cannot open.

Static websites whose files are Blossom blobs, listed by a manifest event: one root site per key, and named sites beside it.

Kind 24, a plain text message addressed to one or more keys, meant for a notification screen rather than a thread.

Kind 30402, a classified listing: something for sale or on offer, with enough structure to be worth querying.

An HTTP file storage API discovered through a well-known document, replaced by Blossom.

Kind 1063, file metadata: the url, the hash, the mime type and the size of a shared file.

Data vending machines: paid jobs requested and delivered as events, reserving the kind range 5000 to 7000.

Assertions a trusted provider publishes about a key, an event or an external identifier, so a client does not have to compute a web of trust itself.
