Ethereum jzz cold Wallet

1.

Generally speaking, blockchain wallet is used to store digital currency. In fact, blockchain wallet does not store digital currency, but a tool to store key (private key and public key). With the key, you can have the right to control the digital currency in the corresponding address, and use the digital currency collection address generated in blockchain wallet, You can accept the digital currency transferred to you by others, and you can also transfer the digital currency you own to others.

classification of digital currency wallets:

can be roughly divided into two categories, hot wallet (online wallet) and cold wallet (offline wallet)

first, hot wallet

Hot wallet is also called online wallet, It includes light wallets and heavy wallets (all node wallets). The wallets that need to be connected to the Internet can be directly traded

1. Light Wallet:

does not store the complete blockchain, only stores the data related to itself. It is small in size and can run on mobile phones, computers, web pages, etc

advantages and disadvantages: it does not occupy memory, supports a variety of digital assets, has a good user experience, is fast for novices, but transaction verification is a little slow

2. HEAVY WALLET (full node wallet)

maintains all blockchain data, completely decentralizes and synchronizes all data. It has better privacy and can verify the validity of transaction data locally

advantages and disadvantages: it has better privacy and faster verification of information, but it needs to synchronize data before each use, takes up a lot of hard disk space, and does not support multiple digital currency transactions

Second, cold wallet

cold wallet is not connected to the Internet, also known as offline wallet; For example, professional hardware devices, or private keys (mnemonics) written on paper

1. Hardware wallet

Hardware wallet is to store digital currency with professional hardware, store the private key of digital assets in a chip, isolate it from the Internet, and plug and play

2. Paper wallet

the advantages and disadvantages of writing the private key on paper and then deleting

cold Wallet:

is relatively safe, but it is very troublesome to create a wallet and trade. It is difficult for novices to operate, and the price of wallets is relatively expensive, generally ranging from thousands to tens of thousands of yuan. If you don't have a large amount of digital assets, you don't need to consider

generally, it's recommended for novices to use light wallet. Light wallet is easy to operate and easy to use. Personal used geekwallet

simple and convenient light wallet supports bitcoin (BTC), lightcoin (LTC), Ethereum (ETH), EOS Storage and management of mainstream digital currency assets such as usdt

using bip44 mnemonics, local private key, off-line signature and other security mechanisms, as well as mobile phone and computer al backup strategy, completely solve the loss of digital currency assets caused by hacker attack, virus infection, mobile phone loss, forgetting mnemonics and other ways, and provide users with online Multi Chain digital assets one-stop management service. The platform also has tiaoshao market, which can carry out token trading of physical assets on the chain

2. 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".

3. World of Warcraft mining skills level 1-375 alliance tribe complete upgrade route strategy

1-75: copper ore (smelting experience, can dig 1-4 times) is associated with poor quality stone and malachite
it's easy to dig in the birthplace, plus smelting experience, 50 + mining experience can be easily achieved

75-125: tin ore (smelting experience, can dig 1-4 times) 50 skill requirements, associated with tiger eye stone, shadow stone, rough stone
tin mine is also a very popular mineral. It is recommended by tribes to go to barren land / coniferous forest; The League recommends Chiji mountain

silver ore (smelting experience, can dig 1-4 times) 75 skill requirements, associated with tiger eye stone, rough stone
silver mine is the first rare mine we can encounter. Copper mine generates silver. That is to say, after a certain copper mine is collected, there is a certain chance to refresh silver mine next time. Of course, silver mine is also used as an independent refresh in advanced map. The tribe here recommends barren land / thousand needle stone forest; The League recommends Chiji mountain

125-175: iron ore (can be excavated 1-4 times) 125 skill requirements, accompanied by heavy stones and topaz
there are many places, but none of them is relatively distributed. However, I still suggest to go to the shining plain at the edge of the thousand needle Stone Forest - & gt; Tanalis, there's a lot of data going back and forth on this line

gold mine (smelting experience, 1-4 times of excavation) 155 skill requirements, accompanied by heavy stones and topaz
this is the second kind of rare ore that we can meet, and the last kind of ore with experience in smelting. Iron generates gold. Similarly, after the iron ore is collected, the next refresh will have a certain chance to refresh gold. Of course, the advanced map will refresh, but it is rare

175-245 mitag mine (can be excavated 1-4 times) 175 skill requirements, accompanied by solid stone, turquoise and ruby
two places are recommended for large-scale collection:
1. Barren land, as shown in Figure 1, will brush three secret silver in area a and two secret silver in area B. the refresh of these two places is very fast, and a circle of maps outside can't be finished, so areas a and B will refresh
2. If you think that there are too many people in the barren land, I recommend a small place, the altrank mountains, as shown in Figure 2. In the cave of area a, 2-3 secret silver will be refreshed each time, and in the refresh point outside, 3 mines will be brushed each time. This place has few people, and the map is small, and the refresh is relatively fast, which is suitable for a large number of collection
300-330, mainly to dig the magic iron ore

first of all, dig many magic iron ores distributed on Hellfire Peninsula clockwise

If Hellfire Peninsula is full of miners, go to ZANZA swamp

330-355, mainly for Moxian iron mine and Jiangang iron mine<

going to nagland grassland and digging hard steel ore can not only improve skills, but also sell ore at a good price

at the same time of digging hard steel ore, magic iron ore can also be collected together, even in the later stage, the consumption of magic iron ingot is still considerable

355-375, mainly for Moxian iron mine and Jiangang iron mine

yingyue gorge is the best choice for mining Jiangang mine

if the level is not enough, you can also choose to practice mining skills in the tiroka forest

don't forget to continue to search for magic iron ore while digging hard steel ore in yingyue canyon<
