Peer Domain System is a decentralized name resolution system which provides strong authentication and prevents name conflicts.

Introduction

One of the design goals is to make it easy to share name resolution data.

Design Goals

strong auth
prevent name conflicts
easy to use
scalable
no single point of failure
integration with existing internet infrastructure (dns, browsers)
hard to take down

Implementation Ideas

Create a DNS server in Python.

Use Cases

single record

PDR - Peer domain record - can be pasted on twitter, discussion forums, web pages, emails and so on

#pdr domain scope record-type value expiry-date signer digest

#pdr magic string
domain is the name to be resolved
scope helps prevent name conflicts
record-type can be a, aaaa, cname
value can be an ip, standard dns name, other pds name

examples:

#pdr openfarmtech 20110311 c openfarmtech.org 0 elifarley 2afqgwk6

expiry is optional
signer is optional

pdz file

a .pdz file has all records of a given domain. A pds client retrieves the file using a dht like kademlia, bittorrent or other p2p apps. Users can also save such files in a specific folder called pdz, which should be shared with everyone.

name#scope@signer.pdz
