The collection of 100 questions in blockchain

1. Do you want to learn blockchain development technology or just want to know what blockchain is? If it is the former, you can look at the code of other blockchain projects and learn about it first. If it is the latter, we can pay attention to some good blockchain we media. Blockchain is an emerging instry. There is no ready-made training course. It depends on self exploration and understanding.

2. So what are nodes
a node is a network node in the blockchain distributed ledger system. By connecting servers, computers and other devices through the network, different types of blockchains have different ways to become nodes. For example, bitcoin participates in trading and mining, and EOS participates in election campaign to become a node
the following is what is a bitcoin full node
bitcoin full node is the node that downloads and preserves complete blockchain data by loading bitcoin clients (including bitcoin unlimited and bitcoin)
because of the congestion of the blockchain transaction network, the author solves the problem by adjusting the broadcast communication, information encryption and decryption, consensus mechanism and transaction verification mechanism. In the whole bitcoin network, from miners to ordinary users can be regarded as a node in the bitcoin network, but because bitcoin has the characteristics of multi centralization, In the whole network, its important role is "bitcoin all nodes."

3. I have been playing currency for many years, and I have used many trading platforms. I think the best one to use is gotc decentralized trading platform. First of all, this platform is a truly decentralized trading platform. On this platform, the power to initiate and agree transactions, as well as the power to quote, are in the hands of users, and the platform has no right to interfere or participate in the reconciliation. It's very safe and reliable.

4. The bitcoin system can adjust the difficulty coefficient to ensure that bitcoin will not be g out too quickly
in order to ensure the stability of bitcoin and dig out a block in about 10 minutes, Nakamoto Tsung designed that the difficulty of getting bitcoin from miners mining should be dynamically adjusted every 2016 blocks (about 2 weeks). After the adjustment, the expected time for each block to be generated is 10 minutes. Now the difficulty factor is about 480ph / s. With the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer and generate new blocks.

5. In Himalayas, Lao Wang talks about finance, which is easy to understand

6. At the beginning, I asked 100 questions about blockchain. The video explanation was very clear. After watching each episode, I would have a general understanding of blockchain. Now I will read some official account articles and block chain media websites, etc., to understand the daily information market. Some public official account has dry cargo, which teaches you all kinds of conceptual things, including the popular DAPP, and how to play and how to create wallet. You can go to see dappdiscover.

7.

Bitcoin (abbreviated as BTC) is a point-to-point, decentralized digital asset proposed by Nakamoto (alias); In 2009, Nakamoto Cong packaged the first block and won 50 bitcoin mining awards, which are halved every four years. According to this calculation, bitcoin is expected to be issued in 2140, with a total of 21 million

do you understand what bitcoin is now? If you don't understand, just continue to look down ~ "blockchain 100 questions" makes you a blockchain brick~

8. That's a sure way to go. Now digital currency is just like the sale of new shares

9. Aapxsr still has 9 times
come on, come on, come on

10. This is equivalent to selling. There must be a service charge.
