Digital asset colored coins can represent intangible assets such as a stock certificate, license, virtual property (game items), or most any form of licensed intellectual property (trademarks, copyrights, etc).

As an analogy, consider stamping a $1 note with a message saying "This is a stock certificate of ACME" or "This note can be redeemed for 1 oz of silver" and then trading the $1 note as a certificate of ownership of this other asset. The first implementation of colored coins, named _Enhanced Padded-Order-Based Coloring_ or _EPOBC_ assigned extrinsic assets to a 1-satoshi output. In this way, it was a true "colored coin," as each asset was added as an attribute (color) of a single satoshi. @@ -204,7 +204,7 @@ u=https://cpr.sm/FoykwrH6UY === Counterparty -((("blockchain applications", "Counterparty")))((("Counterparty")))((("smart contracts")))((("Ethereum Virtual Machine (EVM)")))((("extrinsic asset management")))((("virtual asset managment")))Counterparty is a protocol layer built on top of bitcoin.

The Counterparty protocol, similarly to colored coins, offers the ability to create and trade virtual assets and tokens. In addition, Counterparty offers a decentralized exchange for assets. Counterparty is also implementing smart contracts, based on the Ethereum Virtual Machine (EVM). Like the colored coins protocols, Counterparty embeds metadata in bitcoin transactions, using the +OP_RETURN+ opcode or 1-of-N multisignature addresses that encode metadata in the place of public keys. Using these mechanisms, Counterparty implements a protocol layer encoded in bitcoin transactions. The additional protocol layer can be interpreted by applications that are Counterparty-aware, such as wallets and blockchain explorers, or any application built using the Counterparty libraries.
