Zakura and zcli
ZEC checkout needs a house Zcash node, not a public JSON-RPC for watching payments.
| Piece | Role |
|---|---|
| Zakura | Zcash full node (archive). RPC loopback only. Syncs public mainnet P2P. |
| lightwalletd / compact streamer | Compact blocks for the watcher (127.0.0.1:9067). |
| zcash-devtool (zcli) | Viewing / ZIP-321 / UA helpers used by the runtime. |
The browser never calls Zakura. DREGG compares house tip to a public getblockcount (drift ≤ 2) before offering zec_uri. If the house node lags, ZEC Pay is hidden; native THIOL can still mint.
There is no paid Akash “porch” in the current cut. The house node dials public mainnet seeds.
