Blockchain 100 questions episode 76

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. 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.

3. EOS is a blockchain development platform with strong scalability and support for large-scale commercial applications. First of all, EOS adopts dpos consensus algorithm and other technical means, and is expected to realize millions of transaction requests per second, which will be able to support thousands of commercial dapps. Ethereum is a public chain. Every application running on the Ethereum chain will consume the resources of the whole chain. However, EOS is just a blockchain infrastructure. Developers can freely create a public chain on EOS. The use of resources between chains will not be affected, and there will be no network congestion caused by the huge consumption of indivial application resources. Secondly, there is no need to consume EOS token to transfer and run smart contracts on EOS, which will attract more users

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

8. To put it simply, in the past, transactions were accounted by third-party platforms (Taobao, Jingdong, etc.), and blockchain kept a of this account book for each party (consumers, businesses, third-party platforms), so there was no way to go back on it, and there were more layers of protection
let's give an example. For example, in our usual online shopping, after placing an order, our money will be transferred to the intermediary platform of the third-party payment agency. After the seller delivers the goods and the buyer confirms the receipt of the goods, the buyer will inform the payment agency to transfer the money to the seller's account
however, the transaction mode supported by blockchain technology is different. Buyers and sellers can trade directly without any intermediary platform. After the transaction between the buyer and the seller, the system publishes the transaction information in the form of broadcast, and all hosts receiving the information record the transaction after confirming that the information is correct, which means that all hosts have done data backup for the transaction. If there is a problem with the orders proced by this machine, its data information will not be affected, because there are countless machines backing up data at the same time.
