Colored Coins add-on for Copay Released!

ColoredCoins.org is happy to announce the release of their open-sourced version of the Copay wallet, which allows users to receive, send, and issue digital assets based on Colu’s new implementation.

Copay
is an open-source multisig wallet developed by BitPay and allows a robust and multi-platform Bitcoin experience. The reasoning behind using a fork of Copay instead of creating an entire wallet was to allow a quick release of the Colored Coins feature to the community and to build on top of a stable a well-adopted open-source project – and Copay was the best choice.


This would not have been possible without the cooperation of our friends at BitPay, who really helped us to achieve this integration. We hope to continue exploring the potential for Colored Coin wallets, and are happy to improve the digital asset experience within Copay.

 

“Copay was built as an open-source platform so the community could build upon, and innovate with, true bitcoin wallet technology. It’s great to see a wallet that supports both  bitcoin and colored coins within the same application.”
– Tony Gallippi, Executive Chairman and Co-Founder of BitPay.

 


Our Copay fork will allow any developer to easily add a new “Assets” tab in the bottom of his Copay wallet without any code. This was achieved by using AngularJS plugin module, which allowed us to leverage the wallets capabilities and the Colored Coins API.

 

By using Copay, we are not only allowing users to start experimenting with digital assets, but also showcasing new features never seen in the Colored Coins space. Users will be able to store and manage digital assets with a shared wallet in addition to having a multi platform wallet that can be used on any device – so your digital assets can easily be accessed through your PC and your smartphone in one unified experience.

 

This wallet, together with our block explorer (Which will be released very soon to our Github) and API, is a fully open source Bitcoin 2.0 platform. Our vision is for the community to find original use cases and build more Colored Coins platforms using our code, so this new layer of digital assets on top of the Bitcoin Blockchain with interoperable tools will become a reality.

 

Important: This project is in beta and will require more testing for a stable version. You can start experimenting at your own risk.

API Update

Recently we added an “Advanced Topics” section to our API documentation. Currently this section covers two topics: Metadata encryption and Asset manipulation with Mutlisignature addresses.

Metadata encryption

Our API supports the use of RSA public keys for metadata encryption. Any user can choose to encrypt some or all of an asset’s metadata, by specifying the JSON keys whose values is to be encrypted. The user can also specify the format (‘pem’ or ‘der’ ) and the padding standard (‘pkcs1’ or ‘pkcs8’).

It is important to note that decrypting the file and managing the private keys remains the user’s responsibility, our API only provides support of encryption.

Multisignature Addresses

The new colored coins protocol implementation automatically supports Issuing and transferring assets to and from multisignature Bitcoin addresses (or ‘multisig’ for short). Our API documentation will walk you through a detailed code example of how to do that.

Additionally, we provide the option to transfer assets to a multisig address that is automatically constructed given a list of N public keys and an integer m≤N specifying the minimal number of private keys required to release the funds.

In the future we plan to enhance our API capabilities further, so that the community can benefit even more from the new colored coins protocol implementation developed by Colu.

Community Update – 15.7.15

Getting started with Colored Coins from A-Z!

Many of you has been contacting us with various questions regarding the new implementation like: how to send assets to multiple addresses,
we have decided to create an even more detailed Getting Started Guide.

Here is a detailed example, using the Colored Coins API with NodeJS,
for the following use-case:

Community Update 6.7.15

New feature & improvements on the Block Explorer!
  1. Adding image/icon when issuing an asset
  2. Better visualisation on the metadata

Colored Coins protocol proposal by Colu

New Implementation

The Colored Coins team at Colu has been working over the past few months on creating a proposal for a new Colored Coins implementation. Our intent at the beginning was to achieve consensus between all the existing players in the Colored Coins space (Coinprism – Open Assets, Coinspark and Chromaway) and create one unified protocol for issuing assets over the Bitcoin Blockchain. That has proved to be difficult and time consuming, so we decided to draft our own proposal.

The new proposal was created by our “Colored Coins” team (Rotem Lev, Tal Beja, Eliran Zach) that worked on it for the past 6 months and today we are publishing it together with it’s open-sourced code implementation.

Towards New Colored Coins Implementation

Background

Colored Coins is an open source protocol which enables issuing smart assets on top of the Bitcoin Blockchain. Currently, there are 3 leading implementation in the Colored Coins community (Chormaway, Coinprism and Coinspark). We were inspired by those 3 that certainly laid the foundation for Colored Coins. We have decided there was a room for a more comprehensive and robust implementation, that combines existing ideas but also solves long term problems that may occur.

We are about to release in the next couple of weeks a new implementation for Colored Coins, developed by Colu. ColoredCoins.org will still support all the different implementations and will strive towards interoperability.

The Great Use Cases Index of Colored Coins

There are dozens (if not hundreds) of potential use-cases we could use to leverage Blockchain’s technology to better our lives.

The world we live in needs everything fast, accessible and secured.
Not long are the days we will see more and more implementations using Blockchain’s technology, and for it to become used by mainstream consumers. One future implementation could be governments issuing certifications on top of the Blockchain (we already witnessing them paying a close attention to the subject) and it’s not too hard to imagine a big pop star issuing digital tickets to his concert.

If in 2014, Bitcoin 1.0 caught most of the spotlight and attention in conferences and publications, then we can say that 2015 is the year of Bitcoin 2.0 – the year of Blockchain technology.

The Network Effect

A new breeze of colors is coming in and some exciting things are happening. In order to properly welcome the standard you are waiting for (soon to be released), we have decided to spread ColoredCoins growing network and community by creating the Ambassadors Program.

We were pretty excited seeing lots of you reaching out to us, wanting to become part of it. We can proudly say we’ve got some talented, skilled, visionary people with impressive credentials, who are super passionate with ColoredCoins, and thought they need a proper introduction.

Meet the Ambassadors:
