GAP600 bridges the gap from the time the transaction is published on the bitcoin network until it joins the block chain.

Bitcoin payment processors, ATMs, exchanges, APIs and applications are now able to accept zero confirmed transactions. Via a straightforward API GAP600 bridges the gap from the time the transaction is published on the bitcoin network until it joins the block chain, by immediately confirming transactions before they even reach the block chain.
