Development of IOS Ethereum Wallet

Publish: 2021-05-23 18:30:39
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. If this is only the most basic, it can be done by 100000 yuan. If you need to add other functions, it depends on the difficulty of the functions you add. If you want affordable price and good service, I suggest you consult Shengshi Huacai company. I've used it for two years, and almost no problems have occurred.
3. 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. This is virtual currency. It's too risky. You'd better not play it
5. 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<

6. Link aggregation. Different types of switches support different numbers. You can enter
interface eth trunk? On the switch? It will prompt you with a numerical range
this numerical range is the number of supports. But are you sure you have so many ports to use
for example, you can use two ports for one aggregation. 24 port switching supports 12 aggregations at most< Moreover, link aggregation is the connection between switches. Generally, one uplink and one downlink are enough. Unless you're a core exchange or something special.
