 === Counterparty
 
-((("blockchain applications", "Counterparty")))((("Counterparty")))((("smart contracts")))((("Ethereum Virtual Machine (EVM)")))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.
