How to make Ethereum cold Wallet

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. You need to download an Ethereum wallet

3. No, it only needs the currency supported by the wallet. If the currency not supported by the wallet is transferred in, the coin will be lost. The charging address of each coin is different. Moreover, the wallet is a small platform. I feel that it is not as safe as ZB, but some personal wallets can be used with some amount

4. In fact, Ethereum is a virtual currency like bitcoin. Ethereum is decentralized, accounting by the whole network, and the account book is open, transparent and non tamperable. Unlike bitcoin, Ethereum is a programmable blockchain, which provides a complete set of Turing script language
however, if you want to get blockchain, you still need to get it by mining with hayu miners. However, many people get Ethereum by starting with Ethereum, but that's a big risk! There are certain risks!

5. There are many forms of bitcoin wallets, such as PC or mobile wallet clients, online web wallets, and even small notebooks (paper wallets) or brains (brain wallets) that record the private key of bitcoin. You can choose the right wallet according to your needs

bitcoin wallet can be divided into cold wallet and hot wallet according to the storage method of private key

01. A cold wallet is a wallet that can't access your private key on the Internet

cold wallets often rely on "cold" devices to ensure the security of bitcoin's private key, such as computers that are not connected to the Internet, mobile phones, small notebooks with private key addresses, etc. Cold wallet avoids the risk of hackers stealing the private key, but may face physical security risks, such as computer loss and damage

02. Hot wallet refers to the wallet that can access your private key on the Internet

Hot wallets are often in the form of online wallets. When using hot money package, it is better to set different passwords on different platforms and open secondary authentication to ensure the security of your assets

wallet is actually "a management tool for private key, address and blockchain data".

6. 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.

7. 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.

8. Console is the configuration interface of router. The Ethernet port is an interface between intranet and router. Ethernet is connected with router through eth port
