The product of bitcoin decentralization
above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized
blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcthe emergence, development, amendment, circulation and extinction of bitcoin do not depend on the government, so "whether the government allows" has nothing to do with "whether bitcoin exists"
for example, the birth, development and extinction of the solar system do not need the permission of the government
if bitcoin is exchanged with the government controlled "legal tender" (such as US dollar), the government can influence the performance of bitcoin by controlling the legal tender
if the recognition of such assets reaches the bottom line of% 35 in 2019, the world pattern will be more reasonable, transparent and open
how should we deal with the coming risks- Buy bitcoin quickly to deal with the risk of "no bitcoin".
mining is equivalent to using a mining machine (which looks like a computer host, but it's very difficult to kneel down for tens of thousands) to find it on the Internet according to calculation
what else do you don't understand
In bitcoin white paper "bitcoin: a peer-to-peer e-cash system", Nakamoto explained in detail how he designed the system. Among them, he established the main design principles of all blockchain systems since then
a real peer-to-peer e-cash should allow direct online payment from the originator to the other party without the need to go through a third-party financial institution
although the existing digital signature technology provides some solutions, if a trusted third party organization is needed to prevent "double payment", the main benefits (Brought by e-cash) will be lost
aiming at the problem of "double payment" in e-cash, we provide a solution with peer-to-peer network technology
in this network, transaction records are time stamped, hashed and merged into a growing chain, which is composed of hash based proof of work. If the proof of work is not redone, the resulting records cannot be changed
the longest chain is not only a proof of the observed sequence of events, but also a proof that it is generated by the largest pool of CPU processing power. As long as the computer nodes that control most CPU processing power do not join forces to attack the network itself, they will generate the longest chain and leave the attacker behind
the network itself only needs the simplest structure. Try your best to broadcast the information on the whole network. A node can leave and rejoin the network at any time. It only needs (when rejoining) to take the longest workload proof chain as the proof of the transaction occurred ring the node's offline period
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system
