Does blockchain technology have professional certification
blockchain is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry
in April 2018, a group of scholars from Oxford University announced the establishment of Woolf University, the world's first blockchain University
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data.
in the bitcoin system, the number of bitcoins issued by each block decreases with time. Each block from Genesis block will issue 50 bitcoins to the bookkeeper of the block, and then the number of bitcoins issued by each block will be reced by half every four years (210000 blocks), and so on, until the number of bitcoins is stable at the upper limit of 21 million [19]. There will be a service charge in the process of bitcoin transaction. At present, the default service charge is one in ten thousand bitcoins, which will also be recorded in the block and rewarded to bookkeepers
with the soaring price of bitcoin, more and more people join the bitcoin mining instry. How long does it take to dig a bitcoin? How amazing is the power consumption of bitcoin mining machine? First of all, let's take a look at the "blockchain". The core principle of bitcoin is "blockchain". Each block corresponds to a bill. Linking all blocks is a blockchain. Any transaction information and transfer records are recorded in the blockchain. It should be noted that the blockchain exists in the whole Internet, so no bitcoin holder is worried about the loss of bitcoin
blockchain is probably such a structure. Let's explain it briefly. Taking the bitcoin blockchain as an example, the blockchain is not only bitcoin blockchain. As early as 2009, there was only one blockchain, bitcoin blockchain. In recent years, there have been other blockchains. In a moment, I will also introce the blockchain of Ethereum, or bitstock, as well as various blockchains. After the development of blockchain, Now it has entered the public chain and private chain. Just like bitcoin, the public chain is an account in the world. Bitcoin has only one blockchain in the world, which is owned in the world. Later, it developed to some financial institutions, which want to use blockchain to do things. It can't do things on a blockchain without national boundaries. Bitcoin blockchain is global, There is no sovereignty to manage it, no central organization to manage it, and almost no one can harm it. Not only hackers can't harm bitcoin blockchain, but also the government can't harm bitcoin blockchain.
the latest technology application of blockchain: born out of bitcoin technology in 2008, it provides a decentralized credit establishment paradigm without trust accumulation. The essence of blockchain technology is a decentralized and distributed data storage, transmission and proof method. It replaces the dependence of the Internet on the central server with data block, so that all data changes or transactions are recorded on a cloud system. In theory, it realizes the self proof of data in data transmission, This kind of point-to-point verification will proce a "basic protocol", which is a new form of distributed artificial intelligence. It will establish a new interface and sharing interface between human brain intelligence and machine intelligence
at present, almost all decentralized virtual currencies will use blockchain technology, such as bitcoin, Fuyuan, Laite, doggy and so on.
a person who is engaged in a major he likes and depends on his skills can be practical, stable and confident at any time, which can last for a long time
it's hard to be sober and unmoved in the face of temptation, but we should also stick to it. From user: Mr. Bu
thank you for your invitation
blockchain is a new instry rising in recent one or two years. The heat is pretty good. Some hot money has gone in. It's just that there are still many differences in the understanding of policy disputes, the practicability of blockchain technology, and the realization of implementation
I personally take a cautious attitude
as for the skill training of blockchain, I haven't seen any information of professional institutions carrying out such training and ecation. Even if there is, it is recommended to have a thorough understanding
if you want to research, I suggest that you consider securities funds, securities fund analysts, sponsors (the securities bull's mess)
I hope it can help you. User: Mr. Xing

the specific reasons are as follows: 1. The characteristics of blockchain technology timestamp can solidify the information written in a period of time; 2. Distributed accounting technology can ensure that the information entered in the process of law enforcement can not be tampered with to ensure security; 3. The application of hash algorithm can protect personal privacy and realize public query of information at the same time; 4. The decentralized nature of blockchain determines its scalability, which makes up for the disadvantages of traditional storage
with the help of technical means, blockchain notarization can realize the convenience and efficiency of notarization. Cipher finance mimacaijing focuses on blockchain information.
