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 youRMB: &

Recently, the new blockchain application "oasis" of xiaoman Finance (formerly Network Finance) was launched. This is another blockchain application scenario launched by xiaoman finance after leitzdog, aiming to build a financial service platform based on blockchain ecology in the financial field
at present, many users have started to settle in the oasis, and found that the oasis will proce crystal every day. So how should xiaoman oasis play?
in terms of playing methods, users can register as oasis residents with one click through the Internet wallet, "computing power" is the core ability of oasis residents to obtain "crystal", and "crystal" is the digital asset of oasis ecology, Oasis residents can improve their "computing power" by completing tasks, and computing power will automatically dig digital assets "crystal" for residents. The more computing power users accumulate, the more crystals they get. The total amount of crystal is constant every day, and the output is reced by half every two years. With the passage of time, it will be more and more difficult to obtain, and the early participation will have more advantages
at present, xiaoman oasis is in the internal test period, and the specific function of crystal has not been announced yet. However, the black diamond of Netease can be used for consumption and exchange on the planet. Xiaobian thinks that there is still a lot of room for imagination in the future of xiaoman oasis

utxo is the abbreviation of unspent transaction output, and transaction act is pronounced as X. Utxo is the first specific technical solution adopted by Nakamoto in bitcoin. In the design of bitcoin, there is no account concept
as we all know, the biggest bottleneck restricting the popularity of blockchain has been its slow transaction speed. Bitcoin can only process seven transactions per second, while Ethereum can only process up to 20 transactions per second. Therefore, after bitcoin has existed for more than 10 years, most people have only heard of blockchain, but they seldom use this technology
abey is developed to solve the problem of low efficiency of blockchain and difficult to popularize in a large area. It is an independent public chain. Abey adopts a unique chain governance and chain architecture. Abey, for example, is looking at how to use only 50 active blocks in the chain. When a new block is created, the oldest block is removed from the end of the chain. But its data will still be preserved and archived. If this architecture is successful, the whole chain will be shorter, lighter and more responsive. Abey takes an average of 2 minutes to create a new block. Many studies have proved that this is close to the optimal time for block generation - abey is much more efficient than traditional blockchain Technology (such as bitcoin)< Second, it's very interesting. As you mentioned just now, the operation efficiency of blockchain and Ethereum is relatively low. So what level can abey reach<
Huang Lianjin: theoretically speaking, abey's transaction processing efficiency can continue to expand with the needs of users. The change in efficiency will also depend on the type of actual use case. For example, the first use case built on the core of abey blockchain is the apay systems payment services (a payment) platform. According to the project side, its current efficiency has exceeded the speed and throughput of visa / MasterCard credit card system
in terms of function, the apay platform supports the instantaneous conversion of bitcoin, Ethereum, bitcoin, cash and Leyte into a stable currency called Act (or acash) (linked to the value of the US dollar). Once the user obtains the act, it can be used to trade with other apay users
in addition, users will soon be able to enter the act into the apay encrypted debit card, and then they can consume at any merchant (online and offline) receiving visa / MasterCard, and withdraw legal tender from any ATM in the world. Apay's goal is to become a bridge between cryptocurrency and the real world, bringing cryptocurrency into the mainstream business world< In this way, apay will promote the large-scale application of blockchain technology in e-commerce. Besides, what other achievements does abey team take pride in
Huang Lianjin: abey constructs a loose coupling intelligent contract execution architecture. This means that people can use any programming language or compiler to develop smart contracts on the abey platform. In contrast, developers will not need to be limited to the development restrictions in Ethereum ecology, which will reshape the way smart contracts are built and run in the blockchain
the first smart contract in abey ecosystem is written in C language (C language ranks top three among the most common programming languages in the world). At present, there are more than 5.4 million known C and C + + language developers around the world – compared with less than 10000 solid language developers in the Ethereum ecosystem. In 5-6 years, the expansion rate of Ethereum ecosystem's developers is still expected to be relatively slow.
