Where is the decentralized private key
the first step is to register (open an account) and set the password. The second step is user authentication (KYC). The third step is to recharge. Here comes the key. The third step is the most important. Because you need to charge money to your address in the exchange before you can trade money in the exchange. The address of the exchange is actually a wallet address, but the ownership of the wallet is not the user, but the exchange, that is to say, the private key of the address, you don't have it!!! Do you understand the meaning
well, after recharging, the transaction is finished. The user submits the instruction (hanging order) to the server, and then the exchange will be responsible for matching the transaction, which is exactly the same as the stock. The last is cash withdrawal (withdrawal of currency). Users can send instructions to transfer the currency from the exchange address to their wallet address. The above is the trading mechanism of the centralized exchange. In these steps, all actions will have costs. No matter you recharge, trade or withdraw money, gas and handling charges can't escape
then let's look at the decentralized exchange. The trading mechanism is different from the centralized exchange. The first step is to register (open an account) and set the password. It doesn't make any difference. But then it's a little different. KYC is not used. But because there is a private key, the ownership of this address is completely controlled by the user. The second step is recharging. This is not very different from the centralized exchange. You still have to make your own gas
after recharging, we can also trade in the decentralized exchange. Users can also register orders, and exchanges will also be responsible for matching transactions, but the matching is done by smart contracts. Finally, cash withdrawal (withdrawal of currency) is initiated. After withdrawing currency, users can directly transfer the currency from the address of the exchange to their wallet address. This step is the same as that of the centralized exchange
the above is the trading mechanism of centralized and decentralized exchanges, and the difference between them is also obvious. Because all currencies in the central exchange are under its control, the trading efficiency is very high, and it is similar to the stock trading process, convenient and suitable for most users. Conversely, the risk lies in this. If the exchange itself loses its integrity or is attacked by hackers, the user's capital (currency) is not guaranteed
all the transaction processes of decentralized exchanges are completed by smart contracts, so the transaction efficiency is relatively low (TPS of blockchain technology has always been a soft rib), but relatively, the capital (currency) is completely in the hands of users, so the security is relatively high. In addition, there are also KYC, where KYC is needed for centralization, but not for decentralization, and the security of personal information is relatively high. Compared with the decentralized exchange, the advantages of the centralized exchange lie in the trading depth and the number of users, which are unmatched by the decentralized exchange
therefore, centralization and decentralization have their own advantages and disadvantages. It depends on the user's own choice. They like convenient, centralized, secure and decentralized.
private keys and assets are transferred to the wallet for centralized management. Users don't need to worry about the loss of the private key of this kind of wallet procts, resulting in the loss of funds; However, the capital risk will be more concentrated in the wallet project side and server side. When the centralized wallet is conquered by hackers, users will suffer unnecessary losses
decentralized wallets, commonly known as onchain wallets, have private keys maintained by users and assets stored in blockchains
decentralized wallets are often referred to as onchain wallets. The private key is handed over to the user. If the private key is lost, the wallet will not be able to help the user recover, and the funds will be lost forever. But the decentralized wallet is difficult to be attacked by hackers, and users don't have to worry about the self stealing of the wallet service provider
centralized wallets are where assets are stored, while decentralized wallets are where private keys are stored
except for the exchange, it is not recommended to use the centralized wallet, although losing the private key may help you find it. But there is always a risk that the company will run
a decentralized wallet is equivalent to a channel, a channel where you can master mnemonics to control your assets on the blockchain. For a decentralized wallet, the most important thing is to protect the security of the [private key]
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

@ block chaining
to make complaints about the center is code open source, you can check, ensure that they will not install viruses and upload your personal data. p>

it doesn't matter if the wallet goes out of business, just export the private key and save it to other wallets

the exchange transfer fee is about 30 yuan per time, and the transfer from your wallet is only a few cents per time
since 2013, many decentralized trading platforms have emerged. Different from the centralized trading platform, the decentralized trading platform does not need to register an account, and can participate in the transaction by using the personal digital asset account
secondly, every transaction of the decentralized trading platform is carried out through the blockchain, and it needs to wait for the confirmation of the blockchain before the transaction is successful. At the same time, the decentralized trading platform is not responsible for keeping users' assets and private key information. On the one hand, it avoids the moral hazard of the trading platform, on the other hand, it requires you to keep your private key well
e to the low liquidity and slow transaction processing of decentralized trading platforms, the total transaction volume only accounts for 0.03% of the global total transaction volume of digital assets. At present, the tokens of airswap, kyber, 0x and omisego can be traded on huobi.pro.
The 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
in comparison, the decentralized exchange based on EOS is much better, because its TPS is fast enough to handle the decentralized application at the present stage, and its speed is much better than that on Ethereum. Whaleex, in particular, is very smooth in use, with fast transactions. It is not inferior to those centralized exchanges. Among all decentralized exchanges, whaleex is excellent
therefore, I think the decentralized exchange on EOS may break out faster than that on Ethereum, especially the whale exchange, which will be a dark horse. The smart contract of their home is also the only one that has passed the slow fog security audit. The security is particularly high and the use is assured.
Digital asset wallets include imtoken, bitpai, Kushen, Hufu and so on. Let's talk about it in detail:
when it comes to blockchain digital assets, you can't do without digital wallets. With the continuous development of blockchain technology, digital wallets play an increasingly important role in the blockchain ecology. In the early days, only basic functions such as transfer, storage, and collection were available, Nowadays, digital wallet can not only manage assets, but also manage financial affairs, trade digital assets and guide DAPP of public chain< digital wallet has become an important entry into the blockchain world
we often hear about hot wallets, cold wallets and hardware wallets. What's the difference between them? According to different standards, digital wallets can be classified in different ways. Let's talk about several common classification methods of digital wallets
03 according to the degree of decentralization of wallets, digital wallets can be divided into full node wallets, light node wallets and centralized wallets
all node wallet refers to the wallet that synchronizes all data on the blockchain . For example, bitcoin's all node data has reached several hundred gigabytes. Bitcoin's all node wallet needs to synchronize all data. Although the all node wallet occupies a large storage space, it can achieve complete decentralization
the light node wallet relies on other full node wallets on the blockchain and only synchronizes its own related data, thus realizing partial decentralization for example, our commonly used bitcoin wallets are light node wallets. When using these wallets, it is unrealistic to download only data related to our own bitcoin account, and it is also unrealistic to download hundreds of gigabytes of data
centralized wallet means that all data are obtained from its own centralized server , and the data depends on the wallet service provider's own account book. Its transaction efficiency is very high, and it can basically achieve real-time account arrival. For example, our wallet in the transaction platform is a centralized wallet
