Getting started with blockchain technology, which private blockchain free training is better?

The old partner recommended the Shenzhen chain community.

To give you an easy-to-understand example, you can quickly understand what blockchain is:

In a village, A spent 3,000 yuan to buy a cow for B, how to keep this account?

So, A and B found a mutually trusted C to record the account, but later A and C colluded and refused to admit that A bought B's cattle, so the transaction became a rough problem, and disputes continued.

Later, B had another cow, of course, this time he didn't sell it to A, because A was too creditless, so he gave it to D. This time they didn't look for witnesses, but went to the whole village to yell after the transaction, B said that Wang Er bought me a cow for 3,000 yuan, and D also went to the whole village to shout that I spent 3,000 yuan to buy B a cow, so that many people in the village recorded the transaction. In this way, there will be no bad debts, which is the so-called decentralized, distributed bookkeeping.

So here's the problem!

Are you willing to keep accounts for you when you yell, just because you have a big face?

So, the first person to record accurately, will be rewarded with some bitcoins.

Someone asked, what if two people were the first to record at the same time?

In order to circumvent this problem, it is necessary to set rules, such as answering a question first, or recording with your feet, and it must be written in block letters, and set a series of rules, so that there will be no many firsts.

In the network, there will be a lot of transactions going on every day, and there will be many people who will record and eventually get rewarded with bitcoins, and this process is the legendary mining.

Mining has high requirements for equipment, and these mining computer equipment are called mining machines.

In this way, all the processes are a system of several sheets, and the system will encapsulate the data every 10 minutes to form a box full of data, which we call a block.

Blocks are continuously generated, linked together to form a blockchain.

First of all, if possible, try to choose to study in a first-tier city, after all, it is a technology cluster. Secondly, other aspects are examined, such as faculty, curriculum system, teaching mode, employment salary, tuition hours, etc.

Go straight to the audition and find out what the school is really like.

Take a look at professional blockchain training.

Definition of blockchain

In a narrow sense, blockchain is a chain data structure that combines data blocks in a chronological order, and is cryptographically guaranteed by an immutable and unforgeable distributed ledger.

Broadly speaking, blockchain technology is a new distributed infrastructure and computing method that uses a block-chain data structure to verify and store data, a distributed node consensus algorithm to generate and update data, a cryptography method to ensure the security of data transmission and access, and a smart contract composed of automated scripts to program and manipulate data.

There are many ways to learn about blockchain.

You can buy some blockchain-related books, learn some blockchain-related knowledge, and take notes in your spare time to consult relevant information.

You can participate in some offline blockchain learning and exchange meetings, or participate in some training courses, and some teachers will answer your questions.

To sum up, all roads lead to Rome, and there are many channels to learn blockchain, and the one that suits you is the best.

Hello, blockchain technology is very deep, if you want to learn this, you have to start from the basics, it is recommended to go to Jiuyi Finance to see the knowledge of blockchain technology, and there is also the basic knowledge of blockchain technology in it.

4.Blockchain ecological infrastructure. For example, mobile wallets, hardware cold wallets, trading platforms, blockchain content platforms, etc., this category is currently the blockchain industry with the highest commercial profits, with relatively low thresholds and low risks.

For example, for example, the grandson asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would repay the debt, so he asked the village chief to do a notarization and add the account. This is called centralization.

But if you don't look for the village head, which loudspeaker will shout in the village, "I lent my grandson a hundred yuan for plums!" Please write it down in the ledger", this is called decentralization.

In the past, the village chief was highly respected and controlled the account books of the whole village, and everyone kept the money with him, which was everyone's trust in centralization in the past. Now, everyone is worried that the village chief will secretly embezzle everyone's money, what should we do? So everyone sent a ledger to everyone, and anyone who transferred money between them posted a message through a loudspeaker, and after receiving the message, everyone recorded the transaction in their own ledger, which is called decentralization.

With a distributed ledger, it doesn't matter if the ledger of Lao Zhang or Lao Li's family is lost, because Lao Zhao, Lao Ma and other families have ledgers.

Blockchain is one of the most promising industries in the next 5 years, and it is an emerging field that major financial institutions and top banks around the world are investing in and chasing.

So what exactly is blockchain? Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain.

Blockchain can build a pure peer-to-peer value transfer system, without the need for mutual trust between nodes, the blockchain can ensure the integrity and security of data records in the system, can be separated from the endorsement of third-party institutions, and effectively reduce the complexity and risk of transactions. Blockchain uses an algorithmic proof mechanism to guarantee this trust. Compared to other tooling technologies that are time-consuming and costly, he can automatically match and enforce in real time at a low cost.

Instead of believing in people, it is better to believe in technology, and blockchain technology brings a kind of intelligent trust.

Shortcut Wensi · Chain Innovation Academy It depends on the individual.

You can consult the "Chain People Academy", they regularly have online free courses to share, involving blockchain technology and general education content. Some friends have participated in their offline training courses and have reported that the course design is reasonable and the teachers are good.

As the name suggests, the content public chain is the product of the combination of blockchain technology and the content industry, and the blockchain can become a new industry and new technology, but the content public chain is the product of the combination of the blockchain industry and the content industry.

For example, AQUA Hydrogen Oxygen is such a content public chain project worth knowing, I hope it will help you ......
