About

TLDR;

Application developers should focus on their applications and should not be bogged down with managing UTXOs or XPubs. Developers should be able to use an open-source, easy to install solution to rapidly build full-featured Bitcoin applications.

---

DISCLAIMER

BUX is still considered "ALPHA" and should not be used in production until a major v1.0.0 is released.

---

BUX: Out-of-the-box Features:

• xPub & UTXO State Management (state, balance, utxos, destinations)
• Bring your own Database (MySQL, PostgreSQL, SQLite, Mongo or interface your own)
• Caching (FreeCache, Redis or interface your own)
• Task Management (TaskQ or interface your own)
• Transaction Syncing (queue, broadcast, push to mempool or on-chain, or interface your own)
• Future plugins using BRFC standards

Project Assumptions: MVP

• No private keys are used, only the xPub (or access key) is given to bux
• (BYOX) Bring your own xPub
• Signing a transaction is outside this application (IE: bux-server or bux-client)
• All transactions need to be submitted to the bux service to effectively track utxo states
• Database can be backed up, but not regenerated from chain
  • Certain data is not on chain, plus re-scanning an xPub is expensive and not easily possible with 3rd party limitations

Installation

bux requires a supported release of Go.

go get -u github.com/BuxOrg/bux

Releases are automatically created when you create a new git tag!

If you want to manually make releases, please install GoReleaser:

goreleaser for easy binary or library deployment to GitHub and can be installed:

• using make: make install-releaser
• using brew: brew install goreleaser

The .goreleaser.yml file is used to configure goreleaser.

Automatic Releases on Tag Creation (recommended)

Automatic releases via GitHub Actions from creating a new tag:

make tag version=1.2.3

Manual Releases (optional)

Use make release-snap to create a snapshot version of the release, and finally make release to ship to production (manually).
