Counterparty
Counteparty is a P2P financial platform built on top of the Bitcoin blockchain, that provides secure financial tools and markets, not requiring a third party to use.
If in the future Bitcoin is surpassed by another coin, moving the entire network to another blockchain would take no more than a couple of days.
On Counterparty you can create your own coin(Token) to promote your business, and trade this coin as well as XCP or Bitcoin with other users. You can also make a Counterwallet to store your coins.
It's a common misconception that XCP competes with Bitcoin, while in reality it can't exist without it.
XCP
XCP is the official token of Counterparty, at the time of writing one XCP is worth 12.69$.
The supply of XCP was created in a 'Proof Of Burn' process between January 2nd to February 3rd 2014, in this time anyone could trade Bitcoin for XCP by sending the Bits to a non existing address.
Since these Bitcoins can never be spent again they can be considered burned, allowing XCP to be launched without anyone having a pre-existing supply, even the founders.
Since XCP is used as the fuel for each step of Counterpartys smart contracts, the supply of XCP is constantly decreasing as the fuel is appropriately burned.
