- Remove src/bin/bal-pusher-enhanced.rs (synchronous pusher variant) - Remove bal-pusher.env and bal-pusher.sh from git tracking (now in .gitignore) - Update all documentation to remove references to bal-pusher-enhanced: * 01_project_overview.md * 02_glossary_and_bitcoin_domain.md * 03_architecture_and_data_flow.md * 04_modules_detail.md * 05_api_reference.md (remove rawblock ZMQ section, update references) * 08_security_audit.md (remove references to bal-pusher-enhanced in DoS and ZMQ sections) * 09_references_and_links.md - Build verified: cargo check passes for bal-pusher and bal-server binaries

## Quick Reference
|
|
- **What this file contains:** vision, scope, system components, and mapping to existing documentation.
|

## Vision and Scope
|
|
|
|
`bal_server` is a Rust-based Bitcoin transaction executor server. It receives raw Bitcoin transactions via HTTP, validates them, persists them in a local SQLite database, and coordinates their broadcast on-chain after a locktime condition expires. The system supports multiple Bitcoin networks (mainnet, testnet, regtest, testnet4, signet) and tracks extended public keys (xpub) for fee collection.
|
|
|
|
### Key Goals
|
|
1. **Receive and validate** raw Bitcoin transactions with locktime.
|
|
2. **Store** transactions, inputs, and outputs in a structured database.
|
|
3. **Monitor** new blocks via ZMQ and push transactions to the Bitcoin network when the locktime is satisfied.
|
|
4. **Track** derived addresses and extended public keys for fee accounting.
|
|
5. **Collect and report** statistics about the service.
|
|
|
|
## System Components
|
|
|
|
The project consists of three primary binaries and two shared libraries:
|
|
|
|
1. **`bal-server`**: Async HTTP server (hyper + tokio) that exposes the API for receiving transactions and serving statistics.
|
|
2. **`bal-pusher`**: Async daemon that listens for `hashblock` ZMQ messages and pushes pending transactions to a Bitcoin node via RPC.
|
|
4. **`lib.rs`**: Exports the shared modules `db` and `xpub`.
|
|
5. **`db.rs`**: All database operations and schema creation for SQLite `0.34.0`.
|
|
6. **`xpub.rs`**: Address derivation from xpub/zpub using BIP-84 and the `bitcoin` crate.
