Architecture
Core Modules
Arch is composed of independent modules:
Task Registry — defines what can be done
Proof Engine — verifies actions
Settlement Module — handles payments
Reputation Engine — tracks historical behavior
Modules can evolve independently. Nothing is frozen.
Deterministic by Default
Given the same inputs, the protocol must always reach the same outcome.
No hidden logic. No manual intervention. No discretionary overrides.
This is non-negotiable.
Composability
Other protocols can plug into Arch:
AI agents
robot fleets
marketplaces
infrastructure providers
Arch does not own the ecosystem. It enables it.
Security Assumptions
Arch assumes:
robots can lie
networks can fail
data can be incomplete
The protocol is built for adversarial conditions. Optimism is optional.
