In November 2020, Huawei announced the launch of the Mate40 series of mobile phones that support the digital RMB hardware wallet . It realizes the calculation and encrypted storage of digital RMB based on the "chip", and supports fast transactions between devices based on the "NFC" communication capability, which is conducive to the use of digital RMB on mobile phones. Perhaps, the most profound impression most people had on digital wallets was in January 2021.
At that time, Tongren Hospital affiliated to Shanghai Jiaotong University School of Medicine carried out a digital RMB test , which also explored the payment model based on the digital RMB "hardware wallet" . It is understood that through the digital RMB "visual card" of Postal Savings Bank, payment can be completed by waving the card at the payment terminal in the employee restaurant. There is an electronic ink screen window in the upper right corner of the "visual card", which can display information such as consumption amount, balance, and offline available times. In fact, not only Huawei is developing digital wallets, not only Shanghai Jiaotong University has developed a screen card-type hard wallet, but also digital RMB wearable device wallets have been unveiled . The digital RMB Beijing Winter Olympics pilot was launched on the Beijing Metro Daxing Airport Line. In this event, various forms of "hardware wallets" were displayed, including ultra-thin card wallets, visual card wallets, and badges, watches, bracelets and other wearable device wallets. Everyone has long understood the necessity and importance of the existence and promotion of digital RMB (20 million digital RMB red envelopes landed in Suzhou, embracing the blue sea and blue sky of IPFS&Filecoin). However, many people are puzzled about the importance and necessity of "digital wallets" and why even Huawei has entered the digital wallet track. Next, let's talk about digital wallets.What exactly is a digital wallet?
As the name implies, a digital wallet is a wallet used to store digital assets. It is a tool that helps users store, manage, and trade digital currencies, and is a key infrastructure for digital assets . Users can use the digital currency payment address generated in the wallet to accept transfers from others, or transfer their digital assets to others. Different from wallets in the usual sense, digital wallets record the ownership certificate of each asset of the user, that is, the private key corresponding to each asset of the user. The private key represents the ownership and control of the asset. As long as you have the private key, you have the digital asset, so we generally need to keep the private key properly. Wallets are divided into cold wallets and hot wallets according to the storage method of private keys. Hot wallets are wallets we use when we are connected to the Internet, that is, the wallets we use when trading, such as computer client wallets, mobile APP wallets, web wallets, etc. The advantage of hot wallets is that they are easy to use and more efficient . A cold wallet is a wallet whose private key cannot be accessed by the network, i.e. an offline wallet. Its advantage is that it is very safe and you don’t have to worry about the private key being stolen. Its disadvantage is that transactions are cumbersome. Usually we use hot wallets, but when we hold a large amount of digital currency and do not often use it for transactions, we need to use a cold wallet. Among them, the hardware wallet we mentioned at the beginning of the article belongs to a cold wallet . When we talk about digital wallets, we will also talk about many terms (such as Keystore, wallet address, wallet identification code, etc.), and those terms we often mention are often the key elements of digital wallets. Since we have talked about it in the previous article, we will not explain it in detail. You can read it in the picture below. In general, the rise and development of digital currency conforms to the general law of development of things, and digital wallets are also an inevitable product of the times. The battle for wallets, what is it all about? According to statistics from Cambridge University, the number of digital asset wallet users worldwide reached 35 million in 2018, more than three times the number in 2016. While the number of wallet users has increased significantly, the number of wallets has also shown a wild growth trend, and more and more individuals and companies are actively engaged in the research and development of wallets. Nowadays, wallets have begun to move from behind the scenes to the front stage, and more and more of them are appearing in our field of vision. Not long ago, "Fake digital RMB wallets have appeared on the market" became the number one trending search on Weibo, attracting people's attention. Why are wallets so popular? As blockchain becomes more and more popular and developed, more and more people are entering the digital currency industry. Where should digital assets be stored? It is undeniable that exchanges have monopolized the vast majority of cryptocurrency users and are the largest traffic entry point, but wallets are not only used to store digital assets, but also have functions such as financial management, lending, and transfer. In addition, given that the shadow of the "Mentougou" incident has not yet dissipated and users are paying more attention to privacy protection, wallets have the opportunity to become new traffic entry points in financial management, lending, and application distribution centers. Where there are users, there is traffic and competition. Once a wallet gathers a large number of users, the imagination space of the wallet will become huge. Therefore, wallets have become the second most competitive track after exchanges, and are even expected to become the entry-level existence of the future blockchain world. Why can wallets become the entry point to the future blockchain world? The rapid development of Internet technology has broken the barriers to information transmission and brought human society into the information Internet age. "Knowing everything about the world without leaving your room" has become the most typical feature of the information Internet age. The information Internet solves the problems of information transmission and sharing, but it cannot guarantee the authenticity and privacy of information. Blockchain technology is a new decentralized, anonymous, and tamper-proof technology. As blockchain technology is gradually being used, the Internet is transitioning from information interconnection to value interconnection . With the advent of the value Internet, the control over people's own data has gradually been returned to their own hands. The storage, authorization, and use of data all require a private key management solution, and smart contracts are needed to confirm ownership before it can be used.
“ In the era of value Internet, our own digital identity, DNA information, diet information, exercise information, medical information, movement trajectory, etc. are all stored on the blockchain, and the digital identity on the chain is managed by private keys. If the new coronavirus strikes, relevant epidemic prevention and control agencies need to inquire about our movement trajectories, etc., so they can obtain relevant information in a targeted and accurate manner, and obtain massive amounts of data while fully protecting user privacy, so as to quickly identify and judge and do the best epidemic prevention and control .In the era of value Internet, private keys are equivalent to passwords, smart contracts are equivalent to contracts, and wallets are equivalent to browsers. Only after obtaining the password and signing the contract can you open the door to the browser. Once you enter the browser, there will be more cooperation and transactions. Therefore, wallets will indeed become a core entrance to the blockchain world and the entrance to the value Internet. A look at the development of Filecoin from wallets that support it As the underlying infrastructure of blockchain 3.0 and web3.0, and as the carrier of valuable Internet information, Filecoin has been supported by many wallets. Math Wallet: Math Wallet was the first wallet to support the Filecoin network during the Filecoin development testnet period. Today, Math Wallet has built-in some IPFS/Filecoin applications. As a multi-chain wallet, it can connect the ecosystem between Filecoin and other public chains, allowing users of other public chains to enter another ecosystem more easily and conveniently. We can also understand it as a multi-platform cross-chain wallet.
imToken Wallet: On October 15, imToken officially announced that it will support Filecoin after the Filecoin mainnet is launched. File coin will become the eleventh public chain supported by imToken. Previously, imToken has supported ten public chains including ETH, BTC, ATOM, EOS, TRX, CKB, BCH, LTC, KSM, and DOT.
Filecoin Hardware Wallet: This hardware wallet is started by Create React App, which itself integrates Webpack and configures a series of built-in loaders and default npm.
Whether it is a multi-chain wallet, cross-chain wallet, hardware wallet or other wallets. For Filecoin, the Filecoin wallet is not only the entrance to assets and ecology, but also helps to promote Filecoin to attract more user traffic and promote the long-term development of the Filecoin network efficiently and quickly . Filecoin itself is expected to carry the next generation of the Internet. In time, the huge and prosperous wallet ecosystem of the File coin network will surely give the File coin network an added advantage. The File coin network has brought together a huge wallet ecosystem, developer community, miners, and storage customers, and will surely move forward and be unstoppable. |
