XCP, also known as Counterparty, is a cryptocurrency that was launched in 2014. It is built on top of the Bitcoin blockchain and uses the same proof-of-work consensus mechanism. However, unlike Bitcoin, XCP is not primarily used as a means of payment. Instead, it is designed to be a platform for creating and trading custom digital assets. These assets can represent anything from stocks and bonds to in-game items and collectibles. XCP allows users to create these assets using a simple web interface, without the need for any programming knowledge. Once created, these assets can be traded on the Counterparty decentralized exchange, which is built into the platform.

One of the key features of XCP is its focus on security. The platform uses advanced cryptography to ensure that all transactions are secure and tamper-proof. It also has a built-in multisignature system, which requires multiple parties to sign off on transactions before they can be executed. This makes it much harder for hackers to steal funds or manipulate the platform. Overall, XCP is a unique cryptocurrency that offers a range of features and benefits for users who are interested in creating and trading custom digital assets.
