@owstack/btg-lib v0.0.1

BTG Lib

A pure and powerful JavaScript Bitcoin Gold library.

What this provides

This repository extends @owstack/satoshi-common-lib with bitcoin-gold fork changes

Principles

Bitcoin Gold is an other powerful peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Bitcoin Gold network allows for highly resilient bitcoin gold infrastructure, and the developer community needs reliable, open-source tools to implement bitcoin gold apps and services.

Bitcoin Gold uses a different sighash for transaction signatures. The implementation has been tested against the original bitcoin gold test vectors (see sighash.json in /test). bitcoin gold modifications in script evaluation has not been implemented yet.

Building the Browser Bundle

To build a btg-lib full bundle for the browser:

gulp browser

This will generate files named bch.js and bch.min.js.

You can also use our pre-generated files, provided for each release along with a PGP signature by one of the project's maintainers. To get them, checkout a release commit (for example, https://github.com/owstack/btg-lib/commit/e33b6e3ba6a1e5830a079e02d949fce69ea33546 for v0.12.6).
