Common Service Patterns

Blueprints are used to operationalize off-chain infrastructure with explicit on-chain authorization, payments, and slashing hooks. Common patterns include:

  • Key management + signing (threshold signing, custodial APIs, signing relays)
  • Secure compute (job execution, attestations, verifiable pipelines)
  • Oracles and automation (event listeners, action routers, schedulers)
  • Interop (relayers, message verification, bridge co-processors)

Most teams start from one of the examples above and then:

  1. Define job schemas and handlers in the runner.
  2. Decide how customers pay (pay-once, subscription, per-job).
  3. Decide what counts as misbehavior (and how evidence is produced) for slashing.
