BitGo Offers Instant Settlement
Wirex uses the BitGo Instant service, which provides immediate settlement of bitcoin transactions, CCN reported in February.
There was nothing on the BitGo blog about the attack at the time of this report.
BitGo’s service eliminates the “double spend” potentiality in bitcoin transactions. The service is for users seeking instant bitcoin transactions while securing funds against the possibility that the sender will spend the money elsewhere before the transaction gets confirmed via the blockchain.
BitGo provides immediate transaction settlement using the crypto keys among participating users’ wallets.
