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 chip

uses 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 fast

the 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 you

2. I think bitpie can be considered from the perspective of security. After all, they still have principles and bottom lines, saying that they will not use third-party Apple certificates. The apple version can only be downloaded from overseas app stores. The Android version can be downloaded directly from bitpai's official website.

3. Common wallets are bitcoin QT, mutibit and coin bag. At present, the security and speed of the coin packet are very good.

Matlab neural network toolbox can be used to extract samples first, normalize them with mapminmax function, then establish the network with newff function, set training parameters, train them with train function, and finally see the prediction results with SIM function

in the process of training, there is a performance that can be observed, and its training goal is the goal you set. In the process of training, it will automatically separate a part of the samples as validation verification, which can ensure the fitting. In order to evaluate the effect, the accuracy of the final prediction should be considered

The appendix is an example of BP prediction

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

6. WinRAR, password in more than 8 bits, a bit more complex, basically difficult to crack.

7. In my opinion, the biggest advantage of elecoin technology digital wallet is that it has no service charge, and the experience of super fast transfer and the technical strength of the team guarantee the security. Elecoin focuses on the ultimate experience, safe and reliable. Elecoin digital wallet has zero threshold extreme user experience. The current trading platform has the problem of too high user participation threshold. Many users know little about blockchain before participating, especially the basic security knowledge of digital currency wallet, which leads to the problem of wallet account security. Elecoin focuses on the operation experience of each mobile end user, and the team members have profound experience in the successful entrepreneurship of Internet procts. They pay special attention to the user experience, dig deep into the proct value, and combine with the application scenarios to create this popular proct with zero threshold participation and easy to use. Elecoin has a bank level asset security system, and its team members have the system architecture experience of international level fintech procts, which enables elecoin's system to achieve bank level security and stability.
