Practical application of go language blockchain

1.

(1) The underlying platform of the blockchain is a domestic independent and controllable blockchain platform developed by the science and technology of the blockchain. With the characteristics of high performance, high availability, scalability, easy operation and maintenance, strong privacy protection, and hybrid storage, the platform cooperates with the data sharing and security computing platform bitxmesh, the blockchain open service platform filoop, the supply chain finance platform filolink, and other platforms The deposit service platform filoink and the smart contract security R & D platform meshsec can better support the applications of enterprises, governments, instry alliances and other instries, and promote the efficient circulation of value among multiple institutions

(2) JD chain is the underlying framework of enterprise level blockchain independently developed by JD, and its birth marks that JD has started the construction of "Zhizhen ecology" based on the baas platform of blockchain and the underlying chain of "jdchain". Relying on the "one key deployment" capability of multiple optimization implementation, JD Zhizhen chain service platform has achieved the leading second level blockchain node deployment. In addition, it also has the core advantages of open compatibility with a variety of underlying, enterprise level dynamic networking and other mature applications. The timely launch of JD Zhizhen chain will effectively promote the large-scale implementation of enterprise level blockchain applications in various instries, and promote the construction of China's and global trust economy

(3) thunderchain is a blockchain application project independently researched and developed by netxin technology under thunderchain, which has high concurrency and second level confirmation capability of millions of TPS. Based on the research and development of high-performance blockchain procts, Xunlei has built an open platform of Xunlei chain, which helps enterprises or indivial developers to deploy smart contracts, easily realize the proct and service on the chain, and make the application development of blockchain more convenient

(4) Jingtong blockchain

Jingtong blockchain is the core underlying technology of Jingtong technology's blockchain with independent intellectual property rights. It is an effective decentralized Internet trading network based on blockchain technology, which adopts layered design (5 layers) underlying platform and multi language intelligent contract system, and has realized cross chain function. It has multi-level, all-round and one-stop service capabilities such as private chain, cloud chain and alliance chain. The layout of instry and regional ecology has taken shape

in addition to the above blockchain procts, there are community led LTC, cosmos, iota, Neuros, nuls, MOAC, etc., and enterprise led ripple, stellar, Weizhong bcos, network xuperchain, Huawei, Ping'an, Wanxiang, ant financial services, Zhongan, Bubi, matrix element, secret ape, zhongxiangbit, complex beauty, Shanghai Lianjing, etc

extended data:

blockchain is far more than a technology, which involves the spirit of "multi-party cooperation". In modern society, a lot of things must rely on everyone's cooperation to achieve 1 + 1 & gt; But we should try our best to avoid the problem of "information asymmetry" in cooperation

therefore, members of the alliance should keep accounts and share data together, and make everything public to eliminate "information asymmetry", so as to protect everyone's interests and make the business environment develop healthily. Honest work will get e benefits, if cheating will naturally be known to all. Technology is the foundation to help achieve this pattern. This is the more important "blockchain thinking"

A: practical application of blockchain technology

I. financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics

through the blockchain, we can rece the logistics cost, trace the proction and transportation process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

3. Go language and blockchain are involved in the fields of upper application development of blockchain, lower system development of blockchain, high concurrency server, web and micro service development, distributed development, etc. Go language and blockchain focus on the underlying system of blockchain, which is more in-depth
what I know is that smart podcasting has set up this subject, and some of them will have supporting materials and free courses, so you can go and have a look.

4. Advantages of go language + blockchain training course
1. What are the advantages of go
1: performance
2: language performance is very important
3: developer efficiency & don't be too innovative
4: concurrency & Channel
5: fast compilation time
6: team building ability
7: powerful ecosystem
8: gofmt, Mandatory code format
9: grpc and protocol buffers
can be directly compiled into machine code, independent of other libraries. Glibc version has certain requirements, and deployment is completed by throwing a file
static type language has the feeling of dynamic language. Static type language can check out most hidden problems when compiling, while dynamic language has the feeling that there are many packages that can be used and the efficiency of writing is very high
suitable for people:
1. People who want to learn it technology without programming foundation
2
3. People who have programming experience and want to change careers
learning objectives:
learn go language from 0, and comprehensively cultivate special application-oriented talents of blockchain through the learning of go language< Employment direction:
1. New technology go language development (web development, micro service, distributed)
2. Blockchain development in new areas (cryptography security, blockchain system, blockchain application).

5. In Outland, we choose nagland to mine
compared with
Hellfire Peninsula, most of which are magic iron. Although the fire particles can have a good price and market, the output is too small. Although the proction of soil particles is large, the price is really low, the use is little, and the market is not good
and the distribution of Hellfire mines is extremely unfavorable to circle mining, and most of them are distributed in the upper mountain area,
the water area of zanga swamp is large, and many ore spots are distributed in the water, which is the most criticized one for mining. After drilling in the water, we beat the fish of the caller, g two magic irons, and then slowly climbed to the shore and got on the plane, which is not a waste of time
moreover, zanga swamp is mostly magic irons, and the ore spots are few and the distribution is irregular
not to mention the taloka forest, There are too few mines in this map.
there are many mines in Dao Feng mountain, but the terrain is the most yellow and violent. There are lots of swords and stones everywhere, which is very unfavorable for aircraft flying. However, in view of the small number of people, it can be a good place.
shadow Moon Valley and void storm are too high. Some mines are in the strange pile and can't be found without digging. As soon as the hoe strikes, the sound is everywhere, and the strange will come to you, If you don't kill them, you can't dig them. It's a waste of time. So you don't choose to dig them in these two places. But these two places have fixed points, brush rich gold and gram gold, and herbal medicine. So I recommend the small one to keep watch. As for the large one to dig, forget it. The map is far away and it takes half a day to fly by.
2) tool demand
[[miner's hoe]]. Needless to say, the only one who has been following me since level 6 is him. I have destroyed all the furnace stones
[[big bird]] one, no matter whether you are a dragon or a fish, you can fly fast, of course, the birds in the arena are better
[[horse whip]] one, before reaching the mine, the refresh speed is faster than your flight speed, so he is still necessary
in addition, the highest mining skill is 350, which is absolutely the premise!! (3) recommendation of companion training skills
digging grass, also known as double mining, is not particularly convenient to switch. It is possible that a mine will leak when you dig grass, but it is definitely the most profitable combination of farmers, [[engineering eye]] + [[fast throttling particle aspirator]] can simultaneously display ore occurrences and air masses. However, there are not many air masses around the mine, but it's not bad.
skinning is still a bit interesting. The key is that the cobra in twilight Valley can peel the scales of Cobra. The scales are the material for physical output leg protectors, and only the snakes here and in shadow Moon Valley can proce them. However, it's obvious that the number of snakes in shadow Moon Valley or the surrounding environment is not as good as here. It's also a good choice to peel here if you find someone who is robbing ore.
4) mining time is recommended
generally speaking, it's best when there are few people, so I recommend
prime time: 3:00 a.m. - 9:00 a.m.
Silver time: 9:00 a.m. - 12:00 noon, 1:00 p.m. - 3:00 p.m.
if there is one person robbing ore, you should adjust the time by yourself, For example, if you don't see a mine after flying half a circle, please stop and wait for the mine at your feet to refresh, rather than continue to fly to the next mine. The reason is very simple

it's more profitable to dig fuser in the mainland (there's also a chance to proce all kinds of gems and arcane crystals, which sell well)
it's recommended to go to sirisus
Yashi insect nest, and brush one in the smallest hole, It's possible to brush 2 or 3 ore spots outside, a total of 5 mines. You can calculate by yourself. If you add 2 holes and mine 5 mines outside, don't enter the last hole
in Zora's nest, the holes near the alliance camp are usually painted with only one mine. If you want to mine at the entrance, don't go in. The other two holes are painted with two mines each. They are not painted outside, but the entrance will be painted
generally, the two holes with only one entrance are brushed with two mines, the holes with two exits are brushed with one mine, and one mine can be brushed outside

sometimes fuser silver can be turned into real silver, and sometimes pusher silver can be turned into gold, but it is very rare.

6. I want to take them to the town center

7. It should not be. Ask him which exchange he opens an account in and tell me not to go to a small exchange. That's what I do

8. I don't understand all the digital currency, bitcoin or anything, but I have my own opinion. If you listen to it and think it's wrong, you'll laugh it off. Money is a kind of credit commitment issued by each government, which is used as an intermediate measure of the value of goods purchased. Only with government endorsement, stable government and good reputation can we have purchasing power. So the currencies in those war-torn areas are worthless. Maybe ten jin of currency can't buy an egg because there is no guarantee issued by the government. Similarly, digital currency has never been issued as a guarantee by any government, and no country admits that it can be circulated as its own currency. Therefore, to buy digital currency, you can only sell it at a higher price than when you bought it, and receive the money bought by others. That is to make money. So it's very similar to drumming and passing flowers. The last one must be unlucky, but you don't know if you will be the last one. So, like the Dutch tulip, tulip is one of the biggest scams in the world, Ponzi. The more stir fried, the higher, a tulip can buy a house. But when the last person can't sell, all the tulips are not worth as much as a potato. Digital money, in my opinion, is the same. Buffett estimated that he thought so, so he always said bitcoin was a bubble.

A: the practical application of blockchain technology

I. in financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

the application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain
