Colored Coins is an open source bitcoin 2.0 protocol that enables developers to create digital assets on top of bitcoin Blockchain utilizing its functionalities beyond currency.
The concept of a colored coin is to represent a real world value of an asset in its digital form. This value must be tied to a real-world promise by the asset issuers, that they are bound to honor and redeem the actual value of those digital tokens in the real world when the owner wish to reclaim them.
Colored Coins are created by attaching metadata to a fraction of Bitcoin (Bitcoin dust) in a transaction and can be used to issue Financial assets (securities like shares, commodities like Gold or new currencies), prove of ownership (A digital key to a house, a concert ticket etc.), store records (Documents, Certificates) or create smart contracts.
