gRPC Endpoint

127.0.0.1:5555

Fakenet Command

nockchain --fakenet --bind-public-grpc-addr 127.0.0.1:5555 --no-default-peers

Mock payment lifecycle for escrowed settlement runs.

Uses invariant packs to prove payment safety conditions before a real adapter exists.

Next Actions

  1. Replace mock poke and peek execution with local fakenet adapter calls.
  2. Replace command-backed fakenet metadata probes with stable gRPC-native probes once node surfaces are available.
  3. Persist generated reports under a project workspace.
  4. Add app-specific invariant packs as the NockApp interface stabilizes.
