Distributed Currency Exchange on OpenBazaar

Introduction

OpenBazaar allows for the decentralised exchange of types of currencies using the flexible Ricardian contract system. Currency exchanges are not limited trades between crypto-currencies, but can also facilitate exchanges with fiat currencies using reverisble and non-reversible payment systems.

Currency Exchanges

Fundamentally, currency exchanges require a matching of buy and sell orders at a certain price for a given volume. Firstly, buy and sell orders will be created and issued as a Ricardian contract, formatted according to a specialised 'currency' template in OpenBazaar. Secondly, matching buy and sell orders theoretically will be mediated over exchange nodes, which may also function as arbiters for each exchange. Alternative, buy and sell orders may be matched over the OpenBazaar distributed hash table. Finally, private exchanges can be made bet

JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.

// Bootstrap Mid-Small - col-ms-* - the missing grid set for Bootstrap3.
//
// This is a hack to fill the gap between 480 and 760 pixels - a missing range
// in the bootstrap responsive grid structure.  Use these classes to style pages
// on cellphones when they transition from portrait to landscape.
//
// NOTE: Here I use SASS instead of LESS for styling.  To convert to LESS
// replace '$screen' with '@screen' and '$grid' with '@grid'.
