bal-pusher
bal-pusher is a tool that retrieves Bitcoin transactions from a database and pushes them to the Bitcoin network when their locktime exceeds the median time past (MTP). It listens for Bitcoin block updates via ZMQ.
Installation
To use bal-pusher, you need to compile and install Bitcoin with ZMQ (ZeroMQ) support enabled. Then, configure your Bitcoin node and bal-pusher to push the transactions.
Prerequisites
-
Bitcoin with ZMQ Support: Ensure that Bitcoin is compiled with ZMQ support. Add the following line to your
bitcoin.conffile:zmqpubhashblock=tcp://127.0.0.1:28332 -
Install Rust and Cargo: If you haven't already installed Rust and Cargo, you can follow the official instructions to do so: Rust Installation.
Configuration
bal-pusher can be configured using environment variables. If no configuration file is provided, a default configuration file will be created.

Running bal-pusher
Once the application is installed and configured, you can start bal-pusher by running the following command:
$ bal-pusher [bitcoin|testnet|regtest|]
This will start the service, which will listen for Bitcoin blocks via ZMQ and push transactions from the database when their locktime exceeds the median time past.
