The difference between decentralized and distributed ledger
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/btcblockchain is a decentralized distributed ledger. Blockchain is not something. You can think of it as the Internet. No one will think that the Internet is an object. Blockchain is a new model. If we think of it as an account book, it means that all transaction information is in this book. Due to the characteristics of decentralization, it is not subject to the jurisdiction of a third party
blockchain is a decentralized database in essence. Once the contents in the database are recorded in the chain, they cannot be tampered with, and all the contents can be traced back to their source. The centralized procts may be tampered by the jurisdictional party. Therefore, blockchain traceability is also commonly used to trace the source of goods
there is still a lot of knowledge about blockchain, which is just a simple concept. In depth understanding, we need to take time to look at the news and learn about its landing applications. We can see more about password finance.
if you could predict, you would have become a millionaire
I don't believe in prediction for a long time. The last time I read other people's prediction on the website, I bought it and didn't even match a number
if the landlord really wants to buy it, he should have the right to offer his love
if you buy the same number every day, you will get it one day
PS: the numbers of these things usually don't repeat for several consecutive days. Therefore, it's better not to have your number today too similar to the winning number yesterday
please accept if you are satisfied, thank you
First of all, the following materials should be prepared:
electric energy generator, electric energy amplifier, bucket for water, bucket for magma, switch, push-pull mechanical arm, mechanical arm, blue power line, stone block (other blocks are OK, not wood, will burn). The basic principle is to control the mechanical arm to push out the rock block composed of water and magma. When the mechanical arm pushes out the stone, the power generator and the push-pull mechanical arm will be disconnected in series. In this way, the push-pull mechanical arm will retract, causing the mechanical arm to stop advancing and retract. At this time, water and magma meet to proce new rocks. This is the process of a cycle... Emmmm... Some people certainly don't understand... Hee hee, don't worry, click to see the video below to learn more about how to make a stone brush
