What technology does Chinese digital currency use to ensure secu

1.

Yin Zhentao, deputy director of the law and Finance Research Office of the Financial Research Institute of the Chinese Academy of Social Sciences, said that digital currency faces two risks. The first is the technical level. Digital currency relies on blockchain technology and a system, which will make it suffer from security impact, such as hacker attacks on computer systems. We have seen many practical problems in this process

Zhao Zhanzhan, a special researcher of intellectual property research center of China University of political science and law, believes that digital currency has anonymity, quickness and irrevocability. In addition, bitcoin and other digital currencies have high circulation in the world, so many criminals use digital currency as a new money laundering channel. Moreover, there are many different ways to realize money laundering through digital currency. Generally speaking, the probability of new money laundering being found and investigated is lower than before. Many countries have no effective means and technology to combat money laundering through digital currency. These factors lead to criminals prefer this way of money laundering

2. As long as it is a digital currency, it is impossible to be safe, because there is no perfect thing in the world; Digital currencies are sometimes more insecure.

3. In 2013, vircurex, the third largest trading platform of bitcoin in the world, was attacked twice by hackers, which made vircurex fall into a serious financial crisis. As a last resort, it stopped withdrawing bitcoin, Leyte and other virtual currencies in March 2014
on the morning of February 25, 2014, Mt. GOx, the world's first exchange, stolen 744408 bitcoins in a major bitcoin theft case. According to the average price of bitcoin on the 28th day, it is equivalent to 475 million US dollars. Mt. GOx went bankrupt
on January 26, 2018, coincheck illegally removed about 260000 NEM holders at about 02:57 on that day, and then suspended some functions
on March 7, 2018, the world's second largest exchange, "coin on binance exchange". A large number of users' accounts were stolen. In the face of the hacker attack, this morning, coin an rolled back all abnormal transactions
the above lesson of xuelinlin tells us that no matter how big the exchange is, it can't guarantee the security of core assets and users' digital currency
next, I would like to say that it is safer to withdraw your digital currency to Epay blockchain wallet
Why do you say that< 1. Epay wallet adopts multiple encryption, offline cold storage
2. Bank and risk control system, anti money laundering system
3. Secured transactions are more secure, and it is the first encrypted digital wallet supporting secured transactions in the world
Epay wallet is a digital currency encrypted wallet developed by Epay global payment, and Epay global payment is the best payment channel of global cryptocurrency, The official partner of tether and the world's largest usdt charging platform account for more than 80% of the total usdt, and it is the first digital currency wallet in the world to support the top five legal currencies. Epay global payment was established in 2014 with a registered capital of 200 million yuan. Epay global payment integrates the latest blockchain technology and e-wallet to provide convenient and flexible e-payment, global bank wire transfer, payment gateway and other services for global users with a series of advantages such as diversified payment methods, low cost, high security and trust.

5. All kinds of digital currencies basically have their own official wallets. In addition, there are many app wallets or web wallets that can store multiple currencies, such as imtoken (it supports Rec20 protocol token storage, so it is troublesome for apple to use, and it needs to be downloaded and upgraded with Apple ID in Hong Kong or abroad); 58wallet (all currency wallet, apple mobile phone and Android can download directly, now only support erc20 protocol token storage, later upgrade can store more currency), of course, there are many other wallets, but I think these two are good to use, hope to help you

6. Bitflyer, the largest bitcoin exchange in foreign countries, is headquartered in Tokyo.

7. It's safer to use kushenleng wallet. When storing digital currency, it's not connected to the Internet at all, which avoids hacker attacks and greatly increases the security. The operation process is also very simple and safe.

8. Using kushenleng wallet can ensure the security. When I used to store digital currency, I bought kushenleng wallet, which is very safe and easy to use.

With the advent of digital currency, the encryption algorithm of currency is becoming more and more important. What are the types of passwords

classical cipher types mainly include transposition cipher and rearrangement of alphabetic order messages. For example, "Hello world" becomes "ehlol owrdl"

Diffie Hellman and RSA algorithms have been widely used except for the first public example of high quality public key algorithms. Other asymmetric key algorithms include Cramer schup cryptosystem, ElGamal encryption and various elliptic curve techniques

some well-known cryptosystems include RSA encryption, Schnorr Signature, El Gamal encryption, PGP and so on. More complex password systems include e-cash system, signcryption system, etc. Now more cryptosystems include interactive proof systems, such as zero knowledge proof, which is used for secret sharing

for a long time, information collection and law enforcement agencies have been interested in cryptography. The importance of secret communication is self-evident. Because cryptography promotes privacy protection, it also attracts great interest of cryptography supporters. Therefore, there is a history of controversial legal issues around cryptography, especially since the emergence of cheap computers makes it possible to widely use high-quality cryptography

nowadays, cryptocurrency transactions are semi anonymous, which makes them very suitable for a series of illegal activities, such as money laundering and tax evasion. However, the proponents of cryptocurrency often attach great importance to the anonymity of digital currency and think that it can protect the privacy of users. Some cryptocurrencies are more private than others

Cryptocurrency is a new type of digital asset, which is based on the network distributed on a large number of computers. This decentralized structure enables them to exist outside the control of the government and central authorities. The term "cryptocurrency" also comes from the encryption technology used to protect the network

blockchain is an organization method to ensure the integrity of digital currency transaction data, and it is an important part of many cryptocurrencies. Many experts believe that blockchain and related technologies will subvert many instries, including finance and law. Cryptocurrencies have been criticized for many reasons, including their use for illegal activities, exchange rate fluctuations and the vulnerability of the infrastructure that underpins them. However, digital currency is also praised for its portability, divisibility, anti inflation and transparency

The contract transaction of digital currency is not safe. There are still many loopholes in the digital currency trading platform, for example, the most common ones are as follows:

1. Denial of service attack

denial of service attack is the most important attack against the digital currency trading platform at present. Through the denial of service attack, the attacker makes the trading platform unable to access normally, while the user cannot accurately distinguish the attack degree, It often leads to panic asset transfer, which brings some loss
