1. Go full stack + blockchain course:
a total of 22 weeks, divided into five stages,
the first stage is 4 weeks, go language foundation and network concurrency, learning the introctory go language,
the second stage is 4 weeks, go language practical web development, crawler development, cryptography, consensus algorithm, realizing lightweight public chain, learning the website and crawler that can develop golang, Achieve lightweight blockchain
stage 3, 4-week Ethereum source code analysis and smart contract DAPP development, master Ethereum core and smart contract development, as well as blockchain,
stage 4, 4-week super ledger, bitcoin EOS, source code analysis and smart contract practice, master super ledger development, cat bitcoin, bifurcated EOS after learning, As well as DAPP development of smart contract
phase 5, 6-week project practice, five enterprise level projects, and one year of blockchain project experience after learning
from the characteristics of the language itself, go is a very efficient language, which highly supports concurrency. Go language itself pays more attention to distributed system, and concurrency processing is relatively good, such as advertising and search, That kind of high concurrency server
go language advantages:
excellent performance, can be directly compiled into machine code, does not rely on other libraries, go is extremely fast. Its performance is similar to Java or C + +
concurrency is supported at the language level, which is the biggest feature of go. It is born to support concurrency, and go is the concurrency supported in gene, which can make full use of multi-core and make it easy to use concurrency
the built-in runtime supports garbage collection, which is one of the features of dynamic language. Although GC is not perfect at present, it is enough to cope with most of the situations we can encounter, especially GC after go1.1
it's easy to learn. The authors of go language all have the gene of C, so go naturally has the gene of C. There are 25 go keywords, but the expressive ability is very strong. It almost supports most of the features you've seen in other languages: inheritance, overloading, object, etc
rich standard libraries, go has built a large number of libraries, especially the network library, which is also my favorite part< As like as two peas, br / > built-in powerful tools, Go language is built with many tools chain, the best should be gofmt tools, automatic formatting code, make team review become so simple, code format is exactly the same, it is very difficult to think differently.
cross platform compilation and fast compilation. Compared with the sluggish compilation speed of Java and C + +, the fast compilation time of go is a major efficiency advantage
disadvantages of go language:
package management: package management of go language is absolutely not perfect. By default, it has no way to make a specific version of the dependency library, nor can it create replicable builds. In contrast, python, node and Ruby all have better package management systems. However, with the right tools, the package management of go language can also perform well
lack of development framework: go language does not have a major framework, such as Ruby's rails framework, Python's Django framework or PHP's laravel. This is a heated discussion in the go language community, because many people think that we should not start with using frameworks. This is true in many cases, but if you just want to build a simple crud API, it's much easier to use Django / djrf, rails laravel, or Phoenix
exception handling: go language can help developers deal with compilation errors by simply returning errors (or call stack) through functions and expected calling codes. Although this method is effective, it is easy to lose the scope of the error, so it is difficult to provide meaningful error information to users. Error package can solve this problem by allowing us to add context and stack trace to return error
another problem is that we may forget to handle errors. Static analysis tools such as errcheck and megacheck can avoid these errors. Although these solutions are very effective, they may not be the right way.

4. If bitcoin and Ethernet have different rules, do they have different ways of trading and investment
for a long time, Ethernet has been known as a strong competitor of bitcoin. It wasn't until Andreas antonopoulos claimed that Ethernet was no longer a competitor of bitcoin, which triggered a heated discussion on social networks
people begin to compare the two and discuss the differences in investment and transaction between the two digital currencies< According to Chris burniske, analyst and blockchain proct director of ark investment management company, bitcoin is more used for hedging, while Ethereum, which relies on Ethereum to execute smart contracts, is more seen as a trading tool
bitcoin and Ethereum systems are built on the basis of blockchain, in which transactions are recorded publicly, making currency and asset transactions more convenient and preferential, eliminating the cumbersome middleman
in December 2015, the price of Ethernet currency was less than US $1, but now it has risen to US $15, nearly 15 times in just six months. This achievement is attributed to Ethereum, whose financial contracts are completely executed by software, which has attracted a large number of users to invest
with the previous example of Ethereum, the success of Dao (decentralized autonomous organization) is no surprise. The crowdfunding platform supported by Ethereum raised nearly $150 million from more than 10000 anonymous users. Each participant is given the right to vote, they can allocate funds, choose projects, once the investment project is successful, they can also get a certain degree of dividend reward< There are 670 bitcoin ATMs in the world, and thousands of outlets support bitcoin payment. Unlike bitcoin, Ethereum has not yet emerged in the field of electronic payment. At present, the main purpose of Ethereum is to support Ethereum network (such as Dao) to run programs
David ccini, executive director of the strength in numbers foundation, said:
users' expectations of Ethernet are different from those of bitcoin. Both cryptocurrencies can be used for speculation, but the original function of Ethernet currency is to support the operation of applications. Therefore, users need enough Ethernet coins to run their own app. This is also the problem faced by Dao - unless Dao can continuously generate new Ethernet coins, the payment platform will be in danger of outage.

6. Among the hot topics of blockchain, EOS has always been one that can not be ignored, and the saying "EOS surpasses eth" has always been heard. Before we all focused on the calculation speed, concurrent processing and so on. This paper explains the difference between EOS and eth from more angles, and also shows the author's point of view, that is, if the EOS project is successfully implemented, the public chain is online, and the normal operation, EOS is the killer to eth, it is possible to achieve.
7. In my opinion, the prospect and potential of Ethereum are very good. There are many people who can't afford bitcoin. The price is high and the risk is high. I think Ethereum is more suitable for ordinary people. Of course, the platform is also crucial. It's very difficult to make money without the support of the platform. If you want to invest, it's suggested to go to the head exchange, Zhongyuan. After all, Zhongyuan is the new three exchanges, It's pretty good.
8. Choosing a suitable and reliable hardware wallet is the best protection for your digital assets! The recommendation is to use the decentralized trading platform celletf. Celletf is a comprehensive application platform for defi (celletf. IO). Relying on the deployment of Ethereum public chain, including a number of smart contracts / protocols, passive bidding mechanism and ETF's primary and secondary al market architecture, celletf can embrace the unlimited possibilities of defi with only one site.
9. The following is the positioning of G payment:
G payment (GMPC pay) solves the pain point of digital asset payment, realizes transactions between different currencies, effectively solves the current payment dilemma, and brings more traffic to businesses. The hybrid payment system not only supports GMPC payment, bitcoin, Ethereum, member groups, but also not only the current Columbus members, including tens of millions of people in China, People eager to consume digital assets. The biggest problem solved by the hybrid chain is that it can let the national digital assets circulate freely
Brian Choi, founder of GMPC hybrid chain, said that GMPC hybrid chain technology is the first technology in the world to realize data interaction, traffic transmission and asset transfer between different cross chains and alliance chains. It pioneers gbft consensus protocol, integrates the latest hotstuff BFT idea, and its performance and stability far surpass those of traditional public chains and alliance chains. GMPC hybrid chain technology provides a solid technical background support for global application scenarios of g-payment, and g-payment will also be one of the important landing applications of GMPC hybrid chain. The advent of G payment will break the awkward situation of the existing blockchain payment application, become the pioneer of digital finance, and promote the reform and development of the whole blockchain instry and the existing payment instry
