Brother Lian Blockchain training technology share go language Ubuntu environment

Due to the current user's lack of knowledge of the blockchain, coupled with the shortage of professionals in the blockchain and the lure of high salary, the market has spawned a number of blockchain training institutions. Brother Yun Jong, president of the Blockchain training Institute, says consumers need to be careful to differentiate themselves from the chain of training in the blockchain market.

The go language is optimized for programming multi-processor system applications, with go-compiled programs that are comparable to C or C + + code, and are more secure and support parallel processes.

Ubuntu Install go:

sudo add-apt-repository ppa:gophers/go

sudo apt-get update

sudo apt-get install golang-stable

Or

sudo apt-get install Golang

or download the Go language installation package directly
