According to the investigation by the Securities Daily reporter on the website of the State Intellectual Property Office, as of June 28, the Institute of Digital Currency Research of the Central Bank has announced the application for 63 patents. In 2017, 57 applications for patents were announced, and there were 6 in 2018. However, it is worth noting that Among them, 4 of them involve digital currency purses. This year's patent applications are distributed in the second quarter, in May and June respectively.
Convenience and ease of use
Room for improvement
The development of the blockchain industry requires a new type of digital asset storage, which gave rise to the birth of a digital currency wallet. In the digital asset world, the wallet is a management container for keys (including private keys and public keys). The private key carries out the signature transaction, thus proving that it has the right to export the transaction, and its transaction information is stored in the blockchain instead of being stored in the wallet. The "China Blockchain Industry White Paper 2018" issued by the Ministry of Industry and Information Technology believes that for ordinary For users, the threshold for the use of digital wallets is still high, and convenience and ease of use need to be improved. This is the 'pain point' for digital wallets.
In this year's patent application, the Institute of Digital Currency Research of the Central Bank is working hard to solve the pain points of digital currency purses. The four inventions on digital currency purses have their own focuses, focusing on solving technical deficiencies in digital purse landing, synchronization, cancellation, and related account inquiries. And questions.
According to the patent specification, the invention of a method for registering a digital currency purse, terminal and system can satisfy the requirement of the digital currency issuing institution and connect with a digital currency issuing institution; does not rely on a back-end system; and can be based on the user identity of the existing account system. Open digital currency wallet, realize the indiscriminate experience and smooth transition of the existing financial infrastructure and users; facilitate the realization of interconnection of various application scenarios, which is conducive to the extensive application of digital currency.
'A method for synchronizing digital currency wallets, terminals and systems' can meet the localization characteristics and advantages of digital currency wallets, and interact with digital money wallet service providers and digital currency issuers to facilitate the update of digital currency wallet terminals. And cross-terminal migration and other operations, while securing security, enhance the flexibility of digital currency wallet, which is conducive to the widespread use of digital currency.
'A method and system for digital currency wallet cancellation'. After the user's access information is authenticated, the invention can cancel the relevant records of the wallet currency wallet terminal, the wallet service provider, the digital currency issuance registration agency, etc., and complete the digital currency cancellation process.
'Method and system for querying associated accounts based on digital currency wallet' The invention can provide users with services for querying associated accounts through the wallet service organization on the basis of the digital money wallet terminal.
The centralized release of patent applications also shows the central bank's technical strength in the digital currency field, further accelerating the process of the central bank issuing legal digital currency. Yao Qian, director of the central bank's digital currency research institute, previously told the media: 'The central bank issued a prototype plan for legal digital currency Two rounds of revisions have been completed, and it is expected that the relatively closed application scenarios such as the bill market will be tested first, but there is no clear timetable for the launch.
Digital currency wallet facing
Security Risk
Digital currency purse as an important link in the blockchain industry chain needs to create a more secure and reliable storage environment. The Cheetah Mobile Blockchain Central Laboratory stated in the "2018 Global Encrypted Digital Currency Wallet Security White Paper" that encrypted digital currency wallets The security risks mainly exist in the user's use and the security technology design of the wallet. The security risks in the use of the user mainly include hidden risks of private key hosting transactions, light wallet security issues, input method risks, etc. The technical security risks are mainly reflected in the operation. Environment, network transmission, file storage, applications, data backup, etc.
To this end, the Cheetah Mobile Blockchain Center Lab suggests that for the average user, if there is a security hole in the encrypted digital wallet being used, the developer should switch to another secure encrypted digital wallet application before the developer completes the patched version. And re-create a brand new wallet address, transfer the assets of the old address to the new address by transfer, and finally invalidate the old address.
For wallet application developers, if the application has a security vulnerability, it can be modified as described in this white paper, and then upgraded to the user. Since the old version of the user's private key / mnemonic may have leaked due to vulnerabilities, the only solution The solution is to upgrade to the latest version, and then re-create a new encrypted digital wallet, transfer the old assets to the new wallet address, and then invalidate the old address.
