blockd exposes a curated set of bitcoind RPC methods through the workflow interface as core.* steps. Results are passed through verbatim from bitcoind.

See Core RPC Workflow Results for how to retrieve results and submit requests.

---

Permissions

Methods are grouped into default-allowed and opt-in categories. Any method can be explicitly blocked via bitcoind.rpc_permissions.deny. Opt-in methods require explicit enablement in the configuration file. See RPC Permission Configuration for details.
