I know Joyso's difference from other decentralized exchanges, like IDEX, EtherDelta.
However, as far as I know, there are other hybrid exchanges, like EtherBTC. I'm curious about Joyso's difference from them.
A decentralized exchange is one without a third party service holding the customers’ funds. Instead, trades occur directly between users, cutting out the need for the customer to trust the exchange and their security practices. However, fully decentralized exchanges put orders and order-matching on the blockchain, risking sub-optimal prices and creating delays that frustrate users and create security/arbitrage risks. Poor liquidity is another issue.
JOYSO comprises a decentralized architecture for control of funds and a centralized database for dynamically matching market transactions. Only when a deal is done and tokens are confirmed available is the transaction published on the blockchain. Users do not relinquish control of their assets and have the benefit of a dynamic market where trades are processed sequentially, in near real-time.
