What do #Nostr, #Session, and #Monero have in common? Nostr is an open protocol for decentralized social networks: no single servers, your key is your identity. Session is a private messaging app: it doesn't ask for your phone number, it uses onion routing and distributed nodes. Monero is a privacy-focused cryptocurrency: it hides the sender, recipient, and amounts using advanced cryptography. All three—Nostr, Session, and Monero—share the same root: they seek to minimize dependence on intermediaries and protect privacy. Each approaches this from a different angle: 𑁋Decentralization as a principle Nostr is an open protocol for social networks that does not rely on a single server. Session is a messenger that works without a central metadata server, using a distributed network of nodes. Monero, in the financial realm, was designed to have no bank or authority controlling transactions. 𑁋Privacy and resistance to surveillance Monero encrypts and obfuscates sensitive transaction information (amount, sender, recipient). Session prevents tracking by not asking for phone numbers and by routing messages through an onion-type system. Nostr allows anyone to post and read without the need for identification linked to companies or governments, using only cryptographic keys. 𑁋Cryptography at the core They all rely on public/private keys as the basis for identity and security: in Nostr, your key is your username; in Session, your identity is created on the device; and Monero relies on complex cryptographic techniques (ring signatures, stealth addresses, etc.). In short, they are pieces of the same movement that seeks to give individuals back control over their communication, identity, and money, outside of centralized platforms.
