System Architecture

This page describes the basic installation and configuration of NNCP. If you aren’t already familiar with how NNCP works, I highly recommend you start with NNCP Concepts. This is a companion to, and often a parallel of, the Workflow section of the NNCP manual. Installation Main documentation: NNCP Manual: Installation Section. On that page, you can find links to packages for various operating systems. Building from source Alternatively, if you need to build it yourself, you can download a source tarball and build it from source.

A list of key concepts for building and testing reliable distributed systems, with basic definitions and deep references.

What is NNCP? NNCP lets you securely send files, or request remote execution, between systems. It uses asynchronous communication, so the source and destination need never be online simultaneously. NNCP can route requests via intermediate devices – other NNCP nodes, USB sticks, tapes, radios, phones, cloud services, whatever – leading to a network that is highly resilient and flexible. NNCP makes it much easier to communicate with devices that lack Internet connectivity, or have poor Internet.

A developer podcast host recently said they only use AI for autocomplete. This shocked me. That’s two generations behind today’s state of the art. This is how the field is evolving:

A verifiable credential is a specific way to express a set of claims made by an issuer, such as a driver's license or an education certificate. This specification describes the extensible data model for verifiable credentials, how they can be secured from tampering, and a three-party ecosystem for the exchange of these credentials that is composed of issuers, holders, and verifiers. This document also covers a variety of security, privacy, internationalization, and accessibility considerations for ecosystems that use the technologies described in this specification.
