BitcoinSPVCrx

BitcoinSPVCrx aims to be a Bitcoin SPV Client/Node + Wallet that can run entirely in Chrome and on a Chromebook. It will also eventually work with hardwear wallets like Trezor using chrome's usb HID interface and my chrome-trezor module.

The SPV client + wallet code for this project has been broken out into the bitcore-spv module, to make improvement of each piece easier.

BitcoinSPVCrx is a terrible, terrible, name. I plan to rename it when I come up with something better. Suggestions welcome!

Running in Chrome

To run the app, you do not need to install the developer requirements listed below if you don't want to modify the code. To run the app without building, you should check out the master-built directory, which has the build directory files built and updated from master periodically.

Simply check out master-built, enable "Developer mode" checkbox in the upper-right-hand corner of chrome://extensions and then click "Load unpacked extension..." and pick the build/ directory of this repo.

The build/manifest.json, along with the build/js/background.js file that it points to will tell chrome how to run everything.

If you want to modify the code and run your modifications, you will need to proceed with the development requirements below.

Development requirements

• Chrome 38 or later. If you're on dev channel you should be fine.
• Node + npm.
• Webpack + App dependencies:
  • sudo npm -g install webpack && npm install

Build

To build run: npm run build

Whenever you make changes to the javascript in the *js/ directories, you will need to run this again before re-launching the app from Chrome.

Notes

BitcoinSPVCrx is currently using chrome-net to replace use of node's net module when run in the browser. This replaces net with an implementation of it's interface that uses Chrome's sockets API underneath.

BitcoinSPVCrx also uses js/chrome/chrome-statdns.js to replace node's dns module when run in Chrome. This uses statdns HTTP API to resolve DNS entries for bitcoin node seed-finding. I hope to improve on this in the future, and not rely on a single service for this, but it works for now.
