Samsung Galaxy S10 triggered a global war on DAAP race. Its latest model has Blockchain Keystore and Blockchain Wallet.

The key store is the place where users can keep their private keys to use cryptocurrencies. When investors lost the private keys, namely arithmetic numerical data, they lose their cryptocurrencies. Thus the Keystore is quite essential.

Through the Blockchain Wallet, you can settle bills at shops, both online and offline, which accepts cryptocurrencies.

Samsung set the trend toward popularizing cryptocurrencies. Now Apple and other smartphone makers are likely to follow Samsung’s lead when they unveil new models.

A decade ago when the APP appeared on a mobile app, many people wondered what this means. But in so short a time, many companies have debuted their APPs.

Now people are wondering what the DAPP means. They have little understanding of the Decentralized Application.

Simply speaking, it is the blockchain-based APP. Why is the D added to APP? What’s the difference between APP and DAPP?

Unlike APP, DAPP is no central intermediary. No one can fabricate data and records in the blockchain-based DAPP.

In smartphones and PCs, you can download whatever APPs you want. Soon, you can download whatever DAPPs you want.

Only 1-2 percent of smartphone holders use cryptocurrencies. But in the future, more and more people are likely to use DAPPs on their smartphones to use cryptocurrencies, a Seoul analyst said.

Through the DAPP, you can participate in the blockchain-based online game, post views on cosmetics you use, settle bills through Coinduck online payment system and can buy and sell cat characters.
