UnifiedResourceIdentifier

Routing

with Kademlia Distributed Hash Tables

Closest distance between Node and Content:

  distance = xor(Hash, NodeID)

eXclusive OR of two binary numbers

         01111111
  xor    00101001
  ---------------
  =      01010110

     127

-      42

------------

=     85

XOR Distance is unique per Node and Content but also between any two Nodes!

How do you vote?

Bitcoin is basically majority voting on the global state (blockchain) following a predefined process (longest chain) on a reduced set of possible options (crypto puzzles).

Unanimous decisions (like Paxos, Raft) in which everyone to agrees on a new state.

Remember Routing?

the SAFE  Network

Overview

the SAFE network

A decentralized privacy-first open source data storage and communications network that provides a secure, efficient and no-cost infrastructure for app development.

Peer-to-peer Data Storage

Built-in Data Retentation

Mathematical Deduplication

Encrypted by Default

Self-Auth Registration

 

Infrastructure for

decentributed App

(aka truly anonymous)

Apps

on the SAFE network

Public Names

"DNS" - domain lookup

with a "service" oriented approach

Browser

with a Javascript API to allow direct SAFE access

Interactive Web-Apps

Like a Markdown Editor

or comments on a blog
