mastercoin-tools

What is it?

• Package of mastercoin related tools.
• The intention is to help finalizing the mastercoin spec, and enable easy further coding.

Based on what?

• The code uses the package sx, which is libbitcoin based.
• bugfixes for sx as well as new features like BIP11 and get-pubkey which are needed in mastercoin-tools got merged: https://github.com/spesmilo/sx/commits?author=grazcoin

Aim of this package

• Live update - direct "realtime" interaction with the bitcoin network (using sx).
• Multi platform - python runs on any arch.
• No additional database is needed (obelisk has its own and can be used remotely, and the parser/validator use filesystem and a python dict).
• Alternative code base - use libbitcoin instead of "satoshi client".
• Simple cool and mobile friendly web UI.
• Send transaction directly using a hybrid web wallet (not "Advisor").
• Support for offline wallets.
• Generate parsed data snapshots for download.
• Low CPU requirement on server side (server serves static html files and json which are rendered on the client side).
• API (json).
