Digital currency payment hardware
digital currency is an index character RMB, which is a legal encrypted digital currency. It is not only a payment tool, but also a currency. It is essentially different from Alipay and WeChat payment. P> Alipay, WeChat payment and mobile phone banks are all electronic money, is not digital money. These are all payment methods based on electronic accounts, which are in essence just a process of informatization of legal currency, not digital currency in a strict sense. Moreover, it is completely different from q-coin and bitcoin commonly referred to as q-coin and bitcoin, all belong to virtual currency. Compared with digital currency, the most fundamental difference lies in the difference of issuers virtual currency is the electronization of illegal currency, the issuer is not the central bank, and it can only circulate in a specific virtual environment, such as online game currency, which is mainly used for the purchase of virtual goods, but generally does not have security, so virtual trading platforms, such as smart star Witkey, XX one, XX eight, etc., are designed to provide secure trading protection. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegal digital currency
in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety
take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:
1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.
firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required
then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers
Second, the bank system verifies the financial level motherboard and encryption chipuses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area
Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fastthe reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency
Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank youThe digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods
many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat
extended information:
whether the hardware wallet is safe
the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods
of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind
1. Digital currency
digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and password currency belong to digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
features: the use of P2P peer-to-peer network technology to issue, manage and circulate currency theoretically avoids bureaucratic examination and approval, so that everyone has the right to issue currency
Electronic money means that a certain amount of cash or deposit is exchanged from the issuer and the data representing the same amount is obtained. By using some electronic methods, the data is directly transferred to the payment object, so that the debt can be paid off. Strictly speaking, consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form. In short, when we deposit money into our bank account, there will be an extra number in the bank account, which means how much money we have saved. In this process, we give the banknotes in our hands to the bank, and the bank adds a number to our bank card, which is our electronic currencyfeatures:
< UL >e-money and paper money (or physical money) can be easily converted to each other
the data of electronic currency corresponds to the same amount of physical currency
we need to pay physical money to the issuers of e-money (banks and other financial institutions) in order to exchange for the same amount of e-money
3. The similarity between digital currency and electronic currency: both exist in the form of electronic data
The differences between digital currency and electronic currency are as follows:electronic currency has an issuing institution, and the corresponding amount of physical currency in the institution can be exchanged with physical currency; However, digital currency has no specific issuing institution (decentralization) and can only exist in network data
at present, there is no international consensus on whether digital currency is a currency or not, so in China, the main form of digital currency is "investment proct", which is a rather risky investment proct, and only a few businesses are willing to accept digital currency consumption; Of course, some countries (Germany, etc.) have officially recognized the currency status of digital currency
Generally speaking, the user experience of light wallet is relatively good. Generally, it supports multiple chains and is easy to operate. Light wallet has been used geek wallet , which is not bad. It supports BTC, EOS, ETH, usdt and other mainstream currencies
if the amount involved is relatively large and it is stored for a long time, it uses hardware wallet, which is relatively safer than light wallet and needs to buy hardware, The operation is relatively complicated
