Bitcoin-litecoin exchange Huobi has acquired multi-signature wallet Quickwallet and China's leading BTC/LTC block explorer Qukuai.com.
The company said the acquisition puts it on track to not only become the number one secure bitcoin storage option for the Chinese market, but to gain a significant share of the international market as well.
CEO Zhang Jian will become Huobi's vice president of technology and will have overall responsibility for the company's new business development.
Significance of the deal
Robert Kuhne told CoinDesk the acquisitions served a dual purpose:
Huobi's rapid expansion plans
Quickwallet was launched on 15th July, but such is the intensity of competition and speed of growth in China that Huobi CEO Leon Li decided to bring it immediately into Huobi's family of services.
Huobi will keep the Quickwallet brand separate to its other offerings, but will adjust it to integrate more closely with the other services. Block explorer Qukuai (Mandarin for 'block') was created by the same team as Quickwallet, and was included in the deal.
As soon as the acquisition was finalized, Huobi's team set about translating the new services into English for users outside China.
Already users can make instant deposits from Quickwallet to Huobi exchange accounts, and clicking on a transaction link takes them automatically to Qukuai to see the block chain.
The system supports both bitcoin and litecoin, even allowing users to receive both kinds of coin to the same address.
The benefits of a multi-signature wallet
Quickwallet employs a 'two-of-two' multisig system, meaning one private key is retained by the user locally, while the other is stored on Quickwallet's servers. This means a user cannot double-spend and, as a result, they can get instant confirmation of transfers to other Quickwallet users and deposits to Huobi exchange accounts.
This also makes Huobi the first bitcoin exchange to offer instantaneous deposits from an on-blockchain wallet.
Even if a user's private key is hacked and/or stolen, the thief cannot gain control of the funds. Also, this means no one at Huobi or BitVC has the power to take the coins.
Some multisig implementations have a third key, which is also retained by the user or a third-party for extra security. In this instance, two of the three keys are required to spend or transfer funds.
