-# lbcd Websockets Example
+# lbcdbloknotify

-This example shows how to use the rpcclient package to connect to a btcd RPC
-server using TLS-secured websockets, register for block connected and block
-disconnected notifications, and get the current block count.
+This bridge program subscribes to lbcd's notifications over websockets using the rpcclient package.
+Users can specify supported actions upon receiving this notifications.

-## Running the Example
+## Building(or Running) the Program

-The first step is to clone the lbcd package:
+Clone the lbcd package:

 ```bash
 $ git clone github.com/lbryio/lbcd
+$ cd lbcd/rpcclient/examples
+
+# build the program
+$ go build .
+
+# or directly run it (build implicitly behind the scene)
+$ go run .
 ```

+
+# Execute a custome command (with blockhash) upon receving block connected notifiations.
+$ go run . -rpcuser <RPC USERNAME> -rpcpass <RPC PASSWD> --notls -run "echo %s"
 ```

+## Notes
+
+* Stratum TCP connection is persisted with auto-reconnect. (retry backoff increases from 1s to 60s maximum)
+
+* Stratum update_block jobs on previous notifications are canceled when a new notification arrives.
+  Usually, the jobs are so short and completed immediately.  However, if the Stratum connection is broken, this
+  prevents the bridge from accumulating stale jobs.

Usually, the jobs are so short and completed immediately. However, if the Stratum connection is broken, this prevents the bridge from accumulating stale jobs.	2022-10-17 00:03:13 -07:00
