The Dawn Nexus Registry Protocol

All messages are broadcast using the Archives protocol, which prints all the boilerplate and essential identifying information in the transactions as required for their authentication.

Account

This is a registry of accounts with their public keys for easy checking of signatures and finding encryption keys.

Type

1. USER
   Regular user, Creator, Courier or Consumer, or group/corporate

2. REPLICATOR
   Provides read access to the database for replication

3. VALIDATOR
   Participates in the gossip protocol that ensures the database remains unified across the network

Note that the number of validators can only be changed by hardforks, and the accounts created at genesis; eventually an automatic system for auctioning new positions available to operators already running replicators in the region where there is a need for a new Validator. The initial number of Validators will be 25, projected to expand to 125 as a set of 5 regional sets of 25 after 12 months. Initially 12 validators on the open network will be members of the Dawn Network development team, and 13 will be auctioned in the leadup to going live.
