 The term _Colored Coins_ refers to a set of similar technologies that use bitcoin transactions to record the creation, ownership and transfer of extrinsic assets other than bitcoin. By "extrinsic" we mean assets that are not stored directly on the bitcoin blockchain, as opposed to bitcoin itself which is an asset intrinsic to the blockchain.
