Message & Identity

The atomic unit of ParaDigi Universe is the message. Everything else is built from it.

Message Structure

A message carries three essential parts:

• Content: the media or interaction itself
• References: signatures of related messages, including the publisher’s previous message
• Signature: proof that the message belongs to one publisher identity

Identity as a Collection of Events

Unlike systems where an account is a database record, publisher identity here is:

The set of messages signed by the same private key that form a consistent total-order sequence.

The Cost of Identity

Creating a meaningful identity requires time.

1. Linearity: a publisher cannot maintain two conflicting next states in the same history.
2. Consistency: if the chain forks, participants can stop trusting that identity beyond the fork.
3. Persistence: the longer and more coherent the history, the easier it is for others to evaluate.
