Digital currency wallets are considered to be the traffic entrance in the blockchain world, and even the ultimate form of future exchanges.
data companyStatistadata show thatAs of the end of September 2018, the total number of global digital currency wallet users has exceeded 28 million(Currently the total number of Alipay usersover 900 million). The prospect of digital currency wallets is widely optimistic. Although the market conditions in 2018 are cold, walletsLedger SAS、Cobo、TokenPocket、Kcash、ImTokenand so on have announced that they have obtained financing.

recently,Decentralized digital currency wallet contacted by Odaily qPocket, wants to become the App Store in the blockchain world. qPocket is a public chainQuarkChainQuarkChain's official digital wallet, QuarkChain uses sharding technology to achieve multi-chain parallelism, and its version 2.0 emphasizes flexibility. Currently, qPocket'sVersion 1.1.0has officially launched.
Regarding the public chain QuarkChain as a digital wallet, Zhu Qiang, the technical director of qPocket, said that QuarkChain, as a public chain, belongs to infrastructure, and ordinary consumers cannot experience it directly. As the first mobile wallet integrated with the QuarkChain test network, qPocket enables users who have experience in other token transfers to experience a better transaction experience brought about by QuarkChain's high throughput performance. In addition, qPocket, as the entrance of QuarkChain, will aggregate and display QuarkChain ecological partners and all QuarkChain-based DApps.
Compared with the decentralized wallets imToken and Kcash, the main difference of qPocket is that it supports multi-shard transactions.
Zhu Qiang said that qPocket is the first wallet that supports sharding. It has done a lot of exploration in the improvement of workflow and user experience, assisting users in managing digital assets on multiple shards, and optimizing users’ ability to deploy on different shards. The interaction process of smart contracts.

Shard merge
For the necessity of supporting multi-shard transactions,Zhu Qiang said that the application scenario is when there is an application on a certain shard, but the user needs to transfer tokens from other shards to the shard where the application is located. For example, Zhu Qiang said that if there is a DApp on the 8th shard, the user needs to use the token on the 8th shard to pay for the DApp. However, the user only has enough tokens to pay on the 15th shard. At this time, the user needs to transfer the token on the 15th shard to the 8th shard, and then complete the payment. Of course, if the user's tokens on each shard are not enough to pay, tokens from multiple shards can also be merged into 8 shards.
However, since the wallet is a user-oriented application, why should the process of sharding transactions be presented on the product interface instead of being optimized in the background and directly giving users "fool-like operations" that do not need to be selected?
Zhu Qiang said that sharding technology is not a panacea. While it provides high throughput performance, it will also bring more complexity to the system, including some additional burden on users' cognition. qPocket is also considering exploring a "fool" mode, which can make it easier for users to get started. In the future, the wallet may have two modes. Users may not need to care about sharding when getting started, but users can also enable the advanced mode to finely control the transfer behavior of sharding sub-accounts.
In addition to supporting multi-shard transactions, in terms of transaction speed, Zhu Qiang said that the qPocket developed based on QuarkChain can reach 14000+TPS.
In terms of security, according to reports, the user's wallet private key will only be encrypted and stored in the user's device. Zhu Qiang said that users can manage the private keys of multiple chains through a mnemonic phrase, and users only need to back up once when creating a wallet, which reduces the burden of user backup.
In terms of profit model, unlike the simple and direct profit method of cold wallets relying on the sale of hardware, hot wallets are relatively still in the exploratory stage.Zhu Qiang said that everyone is still actively exploring the profit model, but there is some basic consensus that it will only really come to fruition after the ecological explosion of DApp. qPocket is positioned as the entrance of QuarkChain, and will also focus on building a DApp Store based on QuarkChain, providing a distribution platform and operating environment for DApps, so as to realize commercial value.
The currently launched qPocket version supports tQKC and ETH ecological currencies. Users can conveniently manage the two types of assets by switching. In the future, more currencies will be supported and different types of DApps will be launched.
For qPocket, how to use QuarkChain to attract more developers to develop various DApps and import more traffic will be the focus in the future.
In terms of team, qPocket has about 6 technical members.
