Nostr is not just a decentralized network protocol; it embodies a profound philosophical shift towards a distributed social networking system. Its name, "Notes and Other Stuff Transmitted by Relay," hints at the deeper purpose it serves - to transcend the limitations of centralized control and empower individuals.

In this digital age, where information flows incessantly, censorship has become an insidious force that stifles freedom of expression. By decentralizing power and placing it in the hands of the collective, Nostr challenges us to rethink our relationship with authority. But Nostr's significance reaches beyond mere resistance. This protocol introduces a novel concept - cryptographic validation. By subjecting posts to this process, Nostr fosters an environment where truth and integrity are paramount. It prompts us to question the authenticity of information and demands that we seek deeper understanding.

Nostr and Secure Communication

Nostr offers secure communication without the need for Know Your Customer (KYC) procedures, email sign-ups, or phone number verifications. Instead, the protocol provides users with their own unique public key (npub...) and private key (nsec...), which can be likened to a username and password for their Nostr profile. The public key serves as an address for sharing with others, while the private key grants the user access to send encrypted messages and notes to addresses within the same relay.

Similar to Bitcoin, it is crucial for users to adhere to safe private key practices in Nostr. In this context, the principle "not your keys, not your coins" now extends to "not your keys, not your notes/identity." This implies that without control over one's private keys, there is no control over their digital identity and data on Nostr. Therefore, users must prioritize safeguarding their private keys just as they would in a cryptocurrency setup.

By eliminating the need for traditional identification processes and offering secure communication channels through encryption, Nostr presents a promising solution for individuals seeking privacy and autonomy in their online interactions. Meanwhile, Edward Snowden (npub: npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9 ) took to Twitter to compare traditional social media platforms like facebook, TikTok, and Twitter with Nostr. He emphasized Nostr's open protocol, which allows for unrestricted speech and access to information.

Nostr and Payments

The integration of the Lightning network with Nostr has facilitated the ability for users to tip each other right from the start. However, in order to further enhance this integration, a new NIP (Nostr Improvement Proposal) called NIP-57 has been introduced.

NIP-57 introduces a new note type named "Zap" that represents lightning invoice receipts. These receipts are sent by a lightning node referred to as the zapper. Zap requests notes extract relevant information from a Lightning invoice, such as the payment amount, payee, and payer. This data is then used to create a new event that can be captured by relays (cf. Nostr Relays below) and displayed by clients.

By incorporating lightning receipts into Nostr, clients are now able to showcase lightning payments made by different users on the network. These zaps can be utilized for various purposes including tipping other users, making payments for goods and services, accessing exclusive content, and even deterring spam activities.

In a recent interview with Politico, Jack Dorsey shared his optimistic outlook on the future growth of bitcoin payments. He believes that the introduction of zaps and the rise of global permissionless payments on the internet will contribute to this acceleration.

Nostr Relays

Nostr is not merely an application or platform akin to popular social media platforms such as Twitter or Facebook. Rather, it functions as a communication mechanism that can serve as the basis for a multitude of applications, all of which interact with designated communication hubs known as "relays." This fundamental relationship among users (and their associated keys), relays (acting as servers hosting the pertinent data), and clients (referring to the websites or applications that present this data) establishes the groundwork for an innovative social media encounter.

As a result, Nostr protocol ensures that its data is not stored in a centralized location. Instead, the data is held by relays and propagated throughout the network as long as the relay manager allows it.

Relays usually keep messages for a specific period of time before getting rid of them. Consequently, messages in Nostr can be seen as temporary or short-lived. If users are connected to multiple relays, any events they generate will be preserved in all of these relays. This characteristic establishes a decentralized and lightweight system that does not depend on a single point of failure.

Running Your Own Nostr Relay.
Nowadays, individuals have the convenience of running their own Nostr relay through applications and tools like Umbrel. This advancement allows users to easily back up and maintain control over their data.

By establishing a persistent connection with the relays, Nostr-based clients and apps can seamlessly send and receive events in real-time. These events include actions such as likes, comments, posts, direct messages, and payments. This functionality empowers users to stay up-to-date with the latest information across various platforms while retaining ownership of their data.

Using Nostr

In order to properly comprehend the subject matter, it is imperative to initially grasp the underlying definitions of the subsequent two concepts.

  • Public Key (Username): This key serves as your username and can be shared with others as it’s public.
  • Private Key (Password): Similar to a password, with one significant distinction. Unlike passwords, private keys cannot be reset if lost. This key must be kept confidential. It grants access to your account across all platforms powered by Nostr.

Typically, public keys are presented as strings prefixed with npub1, while private keys use the prefix nsec1. It is essential to securely store your private key, much like you would with a password. To emphasise, losing your private key means losing access to your Nostr account, and if someone else gains access to it, they can take control of your account. Furthermore, unlike passwords you cannot reset your private keys. Keep them safe!

Acquiring a set of keys is a straightforward process. The user selects a client for the Nostr protocol, such as Snort (web), Damus (iOS), or Amethyst (Android), and it generates the keys for them. For added security on the web, the user can use an external signer application like the Alby browser extension or the nos2x extension.

Benefits of using the protocol

The Importance of Self-Expression Autonomy

Nostr offers its users an unparalleled level of autonomy in expressing their thoughts, ideas, and opinions. In contrast to major social media platforms operated by big tech companies, Nostr does not employ content moderation or external measures such as de-platforming to regulate user-generated content.

Safeguarding against Debanking

Unlike certain big tech platforms that collaborate with payment processors or financial institutions, Nostr's decentralized model is intentionally designed to mitigate the risk of debanking. By eliminating reliance on centralized financial intermediaries, Nostr provides users with a safeguard against the suspension or restriction of their financial accounts based on their online activities.

Embracing a Variety of Perspectives and Voices

Nostr's elimination of external measures like de-platforming and debanking creates an environment where diverse perspectives and voices can flourish. Users are actively encouraged to engage in discussions and openly share their thoughts, fostering inclusivity. This inclusive space allows for the expression of controversial or unconventional viewpoints without the fear of punitive actions.

User Communities Empowered

Nostr's approach empowers user communities to establish their own standards and rules. Instead of depending on a central authority to dictate content moderation policies, users collectively shape the rules and guidelines that govern their interactions. This democratic approach enables communities to customize their experience according to their values and preferences.

Competing protocols

It is important to mention that there are some alternative or competing protocols to Nostr that are worth mentioning:

  1. Bluesky (AT Protocol): Bluesky is a federated protocol that aims to combine the convenience and scale of centralized services with the openness and resilience of declized protocols. It enables social platforms with universal search ater account portability. Although it is not fully federated yet, it has a massive waitlist. Bluesky was initially funded by a grant from Twitter (now X) but operates as its own independent entity.
  2. Farcaster: Farcaster is a "sufficiently decentralized" social network where the identity layer resides on the Ethereum blockchain, while everything else is off-chain. It was created by former Coinbase employees and has received funding from Andreesen Horowitz.
  3. Lens: Built by Aave, Lens is a blockchain-based protocol that utilizes NFTs as core building blocks for identity and content. It aims to be an open social graph that any app can integrate with and offers built-in monetization elements for content creators.
  4. Mastodon and other Fediverse: Mastodon, Pixelfed, Peertube, Calckey, etc., are built on top of ActivityPub, a federated protocol connecting various apps in the fediverse. ActivityPub was recognized as a standard by W3C in 2018. Users choose one server to host their data, which can be run by anyone, giving server owners significant control over the user experience.
  5. DSNP: DSNP is an upcoming blockchain-oriented protocol focused on creating a universal public social graph where users have control over their own data and identity. It emphasizes disconnection from financial incentives.
  6. SSB: SSB is a peer-to-peer protocol where each person stores their own content on the network. It is suitable for smaller or local social networks consisting of people who know each other in real life.
  7. Spritely: Spritely is a peer-to-peer protocol designed for small contextual groups and communities. It is being developed by individuals with a long history in the space, including the creator of ActivityPub. Unlike other protocols on this list, Spritely is not intended to be the foundation for large-scale social platforms like X.
