NIP-47 Nostr Wallet Connect draft optional
Rationale This NIP describes a way for clients to access a remote lightning wallet through a standardized protocol. Custodians may implement this, or the user may run a bridge that bridges their wallet/node and the Nostr Wallet Connect protocol.
Terms client: Nostr app on any platform that wants to interact with a lightning wallet. user: The person using the client, and wants to connect their wallet to their client.
Let’s Encrypt is a free and open Certificate Authority that offers SSL/TLS certificates to secure web traffic. In addition to standard domain validation, Let’s Encrypt also supports wildcard domain validation, which allows you to secure all subdomains of a domain with a single certificate. In this tutorial, we’ll walk through the steps of obtaining a wildcard domain DNS TLS certificate from Let’s Encrypt.
Step 1: Prerequisites Before we start, make sure you have the following prerequisites installed on your system:
NIP-39 External Identities in Profiles draft optional
Abstract Nostr protocol users may have other online identities such as usernames, profile pages, keypairs etc. they control and they may want to include this data in their profile metadata so clients can parse, validate and display this information.
i tag on a metadata event A new optional i tag is introduced for kind 0 metadata event defined in NIP-01 :
{ "id": <id>, "pubkey": <pubkey>, "tags": [ ["i", "github:semisol", "9721ce4ee4fceb91c9711ca2a6c9a5ab"], ["i", "twitter:semisol_public", "1619358434134196225"], ["i", "mastodon:bitcoinhackers.
NIP-51 Lists draft optional
This NIP defines lists of things that users can create. Lists can contain references to anything, and these references can be public or private.
Public items in a list are specified in the event tags array, while private items are specified in a JSON array that mimics the structure of the event tags array, but stringified and encrypted using the same scheme from NIP-04 (the shared key is computed using the author’s public and private key) and stored in the .
NIP-94 File Metadata draft optional
The purpose of this NIP is to allow an organization and classification of shared files. So that relays can filter and organize in any way that is of interest. With that, multiple types of filesharing clients can be created. NIP-94 support is not expected to be implemented by “social” clients that deal with kind:1 notes or by longform clients that deal with kind:30023 articles.
Event format This NIP specifies the use of the 1063 event type, having in content a description of the file content, and a list of tags described below:
Application preparation for account First open Google sign in page, log in to your Google account, then go to Google Cloud Platform and create a new Google Cloud Project (if required).
Open the application form while staying logged in, fill it out and wait for Google to send you an email.
Get a Google Cloud Project ID Open https://console.cloud.google.com/apis/dashboard ,
click on your project name in the top left corner, and you will see your Project ID in the pop-up list.
NIP-78 Arbitrary custom app data draft optional
The goal of this NIP is to enable remoteStorage -like capabilities for custom applications that do not care about interoperability.
Even though interoperability is great, some apps do not want or do not need interoperability, and it wouldn’t make sense for them. Yet Nostr can still serve as a generalized data storage for these apps in a “bring your own database” way, for example: a user would open an app and somehow input their preferred relay for storage, which would then enable these apps to store application-specific data there.
NIP-58 Badges draft optional
Three special events are used to define, award and display badges in user profiles:
A “Badge Definition” event is defined as an addressable event with kind 30009 having a d tag with a value that uniquely identifies the badge (e.g. bravery) published by the badge issuer. Badge definitions can be updated.
A “Badge Award” event is a kind 8 event with a single a tag referencing a “Badge Definition” event and one or more p tags, one for each pubkey the badge issuer wishes to award.
NIP-46 Nostr Remote Signing Changes remote-signer-key is introduced, passed in bunker url, clients must differentiate between remote-signer-pubkey and user-pubkey, must call get_public_key after connect, nip05 login is removed, create_account moved to another NIP.
Rationale Private keys should be exposed to as few systems - apps, operating systems, devices - as possible as each system adds to the attack surface.
This NIP describes a method for 2-way communication between a remote signer and a Nostr client.
NIP-57 Lightning Zaps draft optional
This NIP defines two new event types for recording lightning payments between users. 9734 is a zap request, representing a payer’s request to a recipient’s lightning wallet for an invoice. 9735 is a zap receipt, representing the confirmation by the recipient’s lightning wallet that the invoice issued in response to a zap request has been paid.
Having lightning receipts on nostr allows clients to display lightning payments from entities on the network.
NIP-56 Reporting optional
A report is a kind 1984 event that signals to users and relays that some referenced content is objectionable. The definition of objectionable is obviously subjective and all agents on the network (users, apps, relays, etc.) may consume and take action on them as they see fit.
The content MAY contain additional information submitted by the entity reporting the content.
Tags The report event MUST include a p tag referencing the pubkey of the user you are reporting.

Step 1: Install OpenSSL OpenSSL is typically installed on most Unix-based systems, including Linux and macOS. To verify if OpenSSL is installed on your system, run the following command in the terminal:
NIP-23 Long-form Content draft optional
This NIP defines kind:30023 (an addressable event) for long-form text content, generally referred to as “articles” or “blog posts”. kind:30024 has the same structure as kind:30023 and is used to save long form drafts.
“Social” clients that deal primarily with kind:1 notes should not be expected to implement this NIP.
Format The .content of these events should be a string text in Markdown syntax. To maximize compatibility and readability between different clients and devices, any client that is creating long form notes:
NIP-65 Relay List Metadata draft optional
Defines a replaceable event using kind:10002 to advertise preferred relays for discovering a user’s content and receiving fresh content from others.
The event MUST include a list of r tags with relay URIs and a read or write marker. Relays marked as read / write are called READ / WRITE relays, respectively. If the marker is omitted, the relay is used for both purposes.
7zip is a popular open-source file archiving software that supports a wide range of compression formats, including its own .7z format. It also offers strong encryption features, which can be accessed via the command line. In this tutorial, you will learn how to encrypt not only the contents of a file but also the file names using 7zip from the command line.
Step 1: Download and Install 7zip To use 7zip from the command line, you first need to download and install the software.
