Table of Contents



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.


BUX is still considered “ALPHA” and should not be used in production until v1.0.0

BUX: Out-of-the-box Features:

  • xPub & UTXO State Management (state, tip, balance, utxos, destinations)
  • Bring your own Database (MySQL, PostgreSQL, SQLite, Mongo or interface your own)
  • Caching (Ristretto, mCache, Redis or custom)
  • Task Management (TaskQ, Machinery or custom)
  • Transaction Processing (queue, broadcast, update state of xpubs)
  • 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: buxServer or buxWallet)
  • 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 xPub is expensive and not easily possible with WOC and limitations with blockchair


bux requires a supported release of Go.

go get -u github.com/BuxOrg/bux

Built-in Features

Package Dependencies

Library Deployment

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).
