NIPs
Read the standard by the consequence.
A NIP is useful when you can see what it changes: identity, signing, relays, messages, wallets, media, moderation or app data. Start with the product behavior, then open the official text and the implementation trail.
Start here
Use NIPs when a feature needs shared meaning.
You do not need to memorize the whole NIP repository. You need to know which NIP explains the behavior in front of you: the key you sign with, the relay you trust, the wallet permission you approve, the post you publish or the report a community relies on.






Official NIP map
Open every official NIP from one readable map.
The local archive now keeps the direct NIP pages as the canonical route. Background research, source snapshots and older archive pages can remain available, but the hub starts with the standards themselves and the consequence each one has for real products.
Core protocol
Core protocol
17 NIP pagesEvents, tags, replies, commands and the base grammar under every other NIP.
This is the base contract: event shape, signatures, filters and the client-relay conversation every other standard assumes.
NIP-09 Event Deletion Request Core protocolThis NIP defines event behavior that clients and relays need to interpret consistently, especially around kinds, tags and product consequences.
NIP-10 Text Notes and Threads Core protocolThis NIP defines event behavior that clients and relays need to interpret consistently, especially around kinds, tags and product consequences.
NIP-13 Proof of Work Core protocolThis NIP defines event behavior that clients and relays need to interpret consistently, especially around kinds, tags and product consequences.
NIP-14 Subject tag in text events Core protocolThis NIP defines event behavior that clients and relays need to interpret consistently, especially around kinds, tags and product consequences.
NIP-16 NIP-16 Core protocolThis NIP belongs in the NIP map because it gives one piece of Nostr behavior a shared shape instead of leaving each app to invent it alone.
NIP-20 NIP-20 Core protocolThis NIP belongs in the NIP map because it gives one piece of Nostr behavior a shared shape instead of leaving each app to invent it alone.
NIP-21 nostr: URI scheme Core protocolThis standard touches identity and signing: names, keys, links, permissions or external references become easier to carry across apps.
NIP-22 Comment Core protocolThis NIP defines event behavior that clients and relays need to interpret consistently, especially around kinds, tags and product consequences.
NIP-24 Extra metadata fields and tags Core protocolThis NIP defines event behavior that clients and relays need to interpret consistently, especially around kinds, tags and product consequences.

Identity and signing
Identity and signing
11 NIP pagesKeys, names, signers, delegation and the places where trust touches your account.
This is the public social graph: who you follow, how clients rebuild your people layer, and why portability also exposes relationship metadata.
NIP-05 Mapping Nostr keys to DNS-based internet identifiers Identity and signingThis maps a public key to a DNS-based name. It gives you a readable handle without turning identity back into a platform login.
NIP-06 Basic key derivation from mnemonic seed phrase Identity and signingThis standard touches identity and signing: names, keys, links, permissions or external references become easier to carry across apps. It also carries an official caution, so treat it as history or compatibility context before building on it.
NIP-07 window.nostr capability for web browsers Identity and signingThis is the browser signer doorway. It decides whether a web app can request signatures without ever seeing your private key.
NIP-19 bech32-encoded entities Identity and signingThis gives Nostr its shareable prefixes: npub, nsec, note, nevent, naddr and the link forms people actually paste into clients.
NIP-26 Delegated Event Signing Identity and signingThis standard touches identity and signing: names, keys, links, permissions or external references become easier to carry across apps. It also carries an official caution, so treat it as history or compatibility context before building on it.
NIP-39 Linking Profiles to Other Platforms Identity and signingThis standard gives publishing and media a portable form instead of locking creative work inside one client.
NIP-46 Nostr Remote Signing Identity and signingThis moves signing away from the website or app. Remote signing changes the trust boundary around every sensitive click.
