10.1 Stateless by Design

Running PTERI in production

This section explains how PTERI operates at scale, how it behaves under load, and what guarantees it provides in real-world production environments.

PTERI is designed as infrastructure, not an application. Operational simplicity and predictability are first-class goals.


PTERI verification services are stateless wherever possible.

This means:

  • No session affinity

  • No per-user server memory

  • No hidden state between requests

Each request contains everything needed for verification:

  • The message or intent

  • The signature

  • The context (challenge, address, scope)

As a result:

  • Requests can be handled by any instance

  • Horizontal scaling is trivial

  • Failover does not affect correctness

If a verifier goes down, another can immediately replace it.
