Streamity is the first P2P (Peer to Peer) Platform Protecting Transactions with Smart Contracts. The key element of security in streamity is streamdesk decentralized application for exchange of cryptocurrency to fiat money without intermediaries on the basis of smart contracts. The smart contract assures safety for both buyers and sellers by blocking cryptocurrency in the smart contract till the signal about crediting of fiat or ordinary money to the seller's account is received, then it is transfered directly between users. 

I chose this  design because it illustrates the efficiency of the streamity platform and the security the streamdesk application provides. I want to thank @MediaWorks for this contest.
