Tark wallet builds a blockchain wallet payment system to ensure users’ privacy and security

#1

According to Coindesk, the Bank of Canada (BOC) and the Monetary Authority of Singapore (MAS) have used blockchain technology to test cross-border payments with the central bank's digital currency. And the project shows "the potential to increase efficiency and reduce the risk of cross-border payments" of blockchain technology.

Now cross-border payment has solved many problems and is convenient for both businesses and consumers. When the user makes the payment, it will involve privacy issues, in order to prevent and protect the security of users, the blockchain plus cross-border payment makes up for this shortcoming. Its open and transparent, non-tamperable features provide a guarantee for the security and privacy of user assets!



Where is the technical subversion of "blockchain wallet payment"?

With the development of Bitcoin, the blockchain wallet was officially born. Before understanding the blockchain wallet, you need to understand several concepts.

The wallet generally contains the following contents: public key, private key, mnemonic words, keystore, password; the content here is a bit complicated, we will understand it step-by-step. In essence, the wallet and the key are one-to-one correspondence. The fixed key can directly open its own wallet on the network, but in order to avoid the leakage in the process of network transmission, the cryptographer uses the asymmetric encryption technology to invent the public key and private key, the public key is used for transmission, and the private key is used for decryption. For simplicity, we can think that the public key is the bank card number, and the private key is the bank password.

The private key = keystore + password, the private key is composed of fifty or sixty digits containing numbers and case-sensitive letters. In order to facilitate the transaction of digital assets, we can easily transfer digital assets with simple password plus keystore. The mnemonic words are encrypted private keys, basically private keys, which are invented to facilitate the export of the keystore.

As we all know, the reason why the traditional online and offline payment that we use today can be widely popularized in part because of its convenient and quick properties. On the one hand, mobile payments reduce the excessive barriers to cash payments. On the other hand, it meets the user's fundamental need for its immediacy. This has become the mainstream way of payment today.

However, mobile payment is not so perfect. It still has many shortcomings in terms of privacy security, cash withdrawal fees, cross-border international transfer fees, and payment transparency. The emergence of blockchain payment, as well as with its decentralization, non-tampering, and transparency, can just make up for the shortcomings of mobile payment in these aspects, especially in ensuring the privacy and security of users.

Compared with the traditional currency, in terms of issuance mechanism and online transaction circulation, the core concept of blockchain technology is decentralization. Facing the security risks of “center”, blockchain technology can be said to be a good solution.
