1. Ethereum is an open source public blockchain platform with smart contract function. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin. There are many ways to quickly create Ethereum wallet in daily coin collection. According to the operation, it can be completed quickly. After the creation, you can get free virtual coin directly from the website.
2. Before developing wallet, we need to have the following preparatory knowledge
first, what is a wallet and its related categories? Xrv522 can develop blockchain wallets
from the perspective of developers, this article explains to readers how to interact with wallet and how to develop a wallet
How do we understand wallets? In short, it is an entrance to connect the blockchain. At present, mature public chains such as bitcoin and Ethereum have many wallets to choose from. Generally, the wallet needs full access to your user assets, that is, it will ask you to enter the private key. The evil cost of wallet is very low, which is one of the reasons why I suggest to choose open source wallet.

4. In order to understand the blockchain wallet, we must first understand several core concepts
1. Wallet address: similar to the bank card number, a person can have multiple bank cards. Similarly, he can also have multiple wallet addresses. A wallet address can only correspond to one private key
2. Wallet ID: customer ID (name) similar to bank card
3. Public key and private key: the holder of the private key is the holder of the currency in the bank card. The private key can calculate the public key, the public key can generate the wallet address through a series of digital signatures, and the data encrypted by the private key can be decrypted by the public key, or vice versa
I know this area quite well, and I have some ideas to develop a blockchain wallet. After all, it is a high-tech wallet. Before I learned about a development company called Xuanling technology on the Internet, and also consulted the people over there. I felt that it was quite professional. I hope I can help you~

5. Blockchain wallet is the basic token management platform, and even the user's identity management tool. For example, when users want to play the encrypted cat game, they can open their wallet, enter DAPP and use it after selection. They can also download DAPP application through their wallet and use it locally
with the increase of token types and the improvement of the whole blockchain ecosystem, when wallet is no longer simply a tool for storing tokens, sending tokens and participating in crowd funding, it will graally shift from dealing with exchanges and crowd funding projects to using tokens for its own purposes< As the entry value of payment, wallet is the same as the existing mobile payment, and payment can be completed by scanning the code to confirm. With the development of lightning network, lightning network and other off chain payment technologies, or fragmentation, sub chain and other technologies, once digital token payment becomes one of the mainstream payment methods in the future, Cobo and other wallets will have a lot of imagination as the entrance
2. The value of wallets as an asset management platform
now there are opportunities for user wallets to rise. First, there are tens of millions of users, all of them are valuable users. Second, with the development of the whole ecology, derivatives also began to develop, and there was a demand. For example, when users have some tokens, some are long-term value investors. For example, some users will hold bitcoin, Ethereum or EOS for a long time. However, if they only store, they will not make the best use of their assets, which is a waste. At present, there are more and more public chains, more and more protocols and applications, and more and more tokens. Centralized exchanges, decentralized exchanges, and quantitative trading are developing. There are many opportunities for financial management and asset management
3. Wallet is the entry value of transaction
e to the precipitation of many users' digital assets, when users need to trade, the more troublesome point is that they need to transfer to the exchange. If it is congested, it will take a long time, which is easy to delay. On the exchange, if the trading depth is not enough, or the price is not appropriate, it is often difficult to close. If it is a larger order of trading demands, instant delivery or purchase will affect the price fluctuation. If the wallet is combined with some decentralized or centralized exchanges, such as users entering their own ideal price, the matching transaction can be realized as soon as possible. For users, fast transactions can be realized in the wallet, which is also a good demand scenario
4. The value of wallet as DAPP market entry
for wallet, DAPP market entry is absolutely the most imaginative prospect. With the maturity of public chain, especially the graal improvement of EOS, Ethereum and other blockchain infrastructure, some DAPP applications of game, financial, social and pan entertainment are graally developed<
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

6. It is not necessary to compress when the sample dimension is too high
7. This is not very clear, because the research team in the central bank's digital currency is generally the relevant personnel of the central bank departments and their think tanks. As early as 2014, domestic banking institutions began to study digital currency
at present, the central bank's research on digital currency is still at an early stage, and it only plans to launch digital currency, but it is still far away from issuing digital currency. When the central bank studies digital currency, it may study the existing mainstream digital currencies such as bitcoin, Ruitai, dogcoin, etc.

8. In go, the outcome is determined by the number of intersections. The intersection is the result of the intersection of 19 horizontal lines and 19 vertical lines in the chessboard × 19 = 361 points. In technical terms, these points are called "Mu" or "Zi". The last side with more mesh or sub number wins. But generally speaking, the black side should first paste 7.5 mesh to the white side to balance the advantages of the first hand, that is to say, the white side should add 7.5 mesh to compare with the black side. Note that the meanings of "Mu" and "Zi" are different from those mentioned above. Here, "Mu" and "Zi" refer to two different methods of calculating the outcome. Either method can be used, and the meaning is the same
let's first talk about the calculation method of "item": the difference between the number of items on both sides, such as 180.5 items on the black side and 180.5 items on the white side, is that the white side wins 7.5 items, because the black side has to post 7.5 items first
let's talk about the calculation method of "sub": half of the intersection point is 180.5 + 3 + 3 / 4 (half of 7.5 mesh). If one party wins by more than this number, the number of sub winning is the difference between the number of sub winning party and 180.5 + 3 + 3 / 4, which is the same as the above example, that is, white party wins 3 + 3 / 4.
