# Our Philosophy & Fundamentals ### Decentralization * No central authority * No central server * Everything must run on single-board PCs like Raspberry Pi ### Services * Thin services, thick clients * Many small services for different needs * The server that facilitates micro-services is called Node ### Registration in blockchain * Every user has one or many key pairs and one current key pair * User info and user public keys are stored on the blockchain * Node info and node public key are stored on the blockchain ### Encryption * User has key pair(s) to encrypt/decrypt messages and files also sign messages and files. * The communication between User and User is encrypted and signed also communication between User and Node is encrypted and signed. * The user also can have symmetrical ciphers for different purposes. * The Node does not see communication between Users. ### Coin Hours (NCH) a payment system * The NESS tokens you hold in your Fiber Wallet generate NESS COIN HOURS (NCH) 1:1 on an hourly basis. NCH is the currency we accept as a payment method for our services. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
