Dedicated mobile phones for decentralized wallets

1. Centralized wallet, also known as off Chain Wallet, completely depends on the company and server running the wallet. bitcoin stored in the exchange is stored in the centralized wallet (off Chain Wallet). The private key is not owned by the user, but in the wallet project side of the centralized server hosting chain, the fund is usually entrusted to the server
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.

2. Decentralized digital wallet, generally speaking, is a wallet that has no central server, does not need to interact with the central server, and manages (stores, transfers, and accounts receivable) digital currency with private key. The zebra wallet I use is very good. It can be downloaded from the official website. The others are not clear

For users,

may be more convenient,

but it hasn't been realized yet

5. The safety factor of the decentralized wallet is much higher than that of the traditional centralized wallet, and it will not suffer losses e to the failure of the center.

XTT (Xin time token), based on Ethereum erc20 platform, is a decentralized digital currency carrier based on blockchain as payment technology

Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014

extended data:

background

bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years

the blockchain of bitcoin is actually a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network

however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions

In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoin

Yes, this method is commonly known as "moving bricks"

as long as you put the money in your wallet, you can trade on any trading platform. The BTC price on the coin easy platform is about 10% higher than that on other platforms, and it is suitable for "moving bricks"

at present, digital currency is more like an investment proct, because of the lack of a strong guarantee agency to maintain its price stability, its role as a value measure has not yet appeared, and it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investors

the characteristics of digital currency

1, low transaction cost

compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment of high handling charges to payment service providers

2, fast transaction speed

the blockchain technology used in digital currency has the characteristics of decentralization, and it does not need any centralized organization similar to the clearing center to process data, so the transaction processing speed is faster

3, high anonymity

in addition to the physical form of currency can realize the point-to-point transaction without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote point-to-point payment, it does not need any trusted third party as intermediary, and the two sides of the transaction can complete the transaction in a completely strange situation without mutual trust, Therefore, it has higher anonymity and can protect the privacy of traders

But at the same time, it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities

9. It doesn't seem to support Apple mobile download. It can only be used on Android phones.

10. You can find it on the Internet by yourself. Anyway, the one who supports NFC is
