Nostr uses a public key system, where your identity is tied to a unique cryptographic key. You have full control over your identity without relying on any central authority. Nostr's protocol eliminates the need for Know Your Customer (KYC) processes. No email, ID, thumbprint, or eyeball scans required! Your privacy is entirely yours to keep.
In Nostr, users sign their posts with their cryptographic keys. This cryptographic signature ensures the authenticity of your data, and enables you to maintain ownership of it. Each client validates these signatures, ensuring data integrity. Users select relays for data exchange, and relays communicate directly with users, not with each other.
In Nostr, you maintain your audience. Users choose their preferred relays and can recommend relays to each other to stay connected. Even if you switch relays, your audience can find your posts by locating your public key. Additionally, users can mute other users, words, and contents, shaping their social media feed according to their preferences. (Features will vary by client)
You can publish anything you want as long as relays are willing to accept it. If no relay will accept what you have to say, you can easily run your own. Relays can operate under any policies their operators may choose, including the ban of specific users or content. When you begin publishing to different relays, your followers' client should be capable of finding you there, so that they can continue receiving your updates.
Nostr supports user anonymity. Users can choose to be anonymous or use pseudonyms without compromising their ability to participate. Nostr is also available On TOR to prevent tracking. Nostr does not have the capacity to provide user data to governments, safeguarding users' freedom of expression from prohibitions or restrictions.
Nostr encourages development and customization. Anyone is free to develop on the protocol, contributing to the growth and evolution of the network. All Nostr clients, relays, tools, and apps that are built can benefit from every past and future development. Builders have the freedom to establish payment methods for their applications and features, providing a potential source of revenue like never before.
With Nostr, there is no central provider who owns your account. In fact, your account is powered by cryptography, and you could create one (or more!) yourself by hand, with no limitation. The easiest way, though, is to use our new online wizard to generate you new account in seconds. Then, you can use it across all of Nostr!
An account is a key-pair. The private key (nsec) is your digital identity. If it is lost or exposed, there is no means to recover access or change credentials. You need to keep your private key safe ans secure. Use a password manager, make a backup on paper, and use it ONLY in trusted apps. Never enter your nsec in a website. Install a signer extension to use your key safely on the web.
Nostr developers have already built several applications to cover many different uses. The easiest way to start using Nostr is to download a social client and get involved. Learn with and through the community by engaging in conversation. Need help? Use the #asknostr hashtag!
After you are familiar with the basic concepts, you can set up your preferred key management tool to explore other social clients and Nostr applications. You already have your digital identity and it works everywhere. Simply login in using your Nostr signer app, signing extension, or nsec. If using your private key, be sure the app is from a trusted source!
