Miden network transaction builder

miden-ntx-builder is a Miden node binary that creates network transactions for network accounts. It is part of the Miden node repository; see the repository README for the overall project layout.

Role

The network transaction builder syncs blocks from an upstream node, tracking network notes and accounts. It starts per-account workers for network accounts with pending work. Each worker selects viable notes, constructs a transaction, proves it, and submits the proven transaction back through the upstream node's RPC API.

The builder can use a remote transaction prover through miden-remote-prover, or fall back to in-process proving where appropriate for local development. It also exposes an internal gRPC API that the node RPC component can use for network-note status queries.

Operation

The builder has its own persistent database and must be initialized from the same trusted genesis block as the rest of the network before it starts. In a complete node deployment, node connects to this service so network-note status can be exposed through the public RPC API.
