Blockchain is a mistake for bitcoin

Publish: 2021-04-20 00:11:10
1. blockchain is a disruptive technology. In the case of Internet supporting the release and digital transmission of information, blockchain can identify property ownership, making it unique and traceable

at the same time, it can provide mutual trust for transactions by using trusted self-executive code, so as to rece uncertainty and promote digital transfer and asset transactions

bitcoin is the most well-known blockchain as an encryption currency that uses blockchain technology to realize alternative payment. Bitcoin is a kind of unlicensed blockchain, also known as public blockchain, which does not restrict the identity of users who consume bitcoin or participate in verifying the authenticity of transfer blocks in the blockchain (an energy intensive process, also known as "mining"). These miners get token, or bitcoin, in return, and given that everyone can view the block (though anonymously), the blockchain itself is somewhat transparent

bitcoin is controversial and banned by many countries e to user anonymity to a large extent. However, it is worth noting that the anonymity and energy use of bitcoin are its own characteristics, not the characteristics of the whole blockchain technology.
2.

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/btc

3. At present, there are many such teams, and the blockchain is suitable for all walks of life, but before the early cooperation, we must pay attention to the team strength and effect. The baker chain blockchain that we understand has a good evaluation in the instry, good reputation and good performance in all aspects. The evaluation of the instry is quite high.
4. Method 1: enter DFU mode when power on
connect the device to the computer with USB cable, and then you will hear the prompt sound that the computer has been connected successfully
please turn off the device first, and then you will hear the prompt that the computer is not connected successfully
first press and hold the power key to display the apple logo, and then press and hold the on / off key and the home key until the logo disappears. Continue to press and hold the power key for about 4-5 seconds, and continue to press and hold the home key until an iPhone in recovery mode is detected by iTunes (if successful, the iPhone should be in black screen). If redsn0w is used to detect, the device model in DFU will be displayed at the bottom of the interface< Method 2: enter DFU in any state (white apple or unlimited restart)
connect the device to the computer
Press and hold the on / off key and home key directly until the logo disappears. Just follow the above steps
method 3: do not press the key to enter the DFU (it is recommended to use the device with damaged key)
download the firmware of the device corresponding to the latest system version (do not use the firmware that Apple has closed for verification)
Download redsn0w and enter extra even more DFU IPSW in turn
at this time, redsn0w will prompt you that this is the operation of making DFU firmware, not the normal operation of restoring the system. The choice is
after selecting the latest official firmware, redsn0w will start making DFU firmware and wait for completion
Open iTunes, close redsn0w, shift + restore (for Mac, please use option + restore) and select the DFU firmware (prefixed with enter)_ DFU), wait for error 37 in the recovery process. At this time, the device is already in DFU mode.

It's real-time analysis. He has different situations every year, every month, every day

6. Xidan share:

some partners call me these days to ask me when the price of currency falls like this, and I say you have no bottom in your heart

I have never dared to expect that the price of RMB will fall below 2.5 yuan, and falling below 2.5 yuan is not in line with the profit demand of customers and the repeated purchase demand of fumigants

as a result, the family members are tough enough to sell more and more until the price of your currency soars, and they can't even catch up with [shiver]

the real money speculators can buy at a low price and make a profit<

the real leeks, throw away their 4 yuan and 5 yuan coins, also have to say, bit light is a liar, suffer losses, be cheated, do not sell still have to fall, such people I directly pull black, lazy to ink with you, anyway, the first group of people who come into the market have made money, I do not need to say [OK]

when I do the market, someone asked me, How do you prove that bitlight is true? I said, do you say bitcoin and radar coin are true? They said, of course, they are true. I said that 1200 yuan buyers of radar coin said that radar coin is fake, 140000 buyers of bitcoin said that bitcoin is a giant liar [arrogance]

9 yuan buyers of radar coin said that radar coin is too good, I'm crazy, People who buy bitcoin for 100 yuan say that bitcoin is God. In a word, the price you buy determines the authenticity of the coin, and your affordability determines the value of the coin.

you must be firm in your belief, because we are not only playing with coins, but also more and more real enterprise block chains are landing and applying. President Han and Yuan are always the first people to eat crabs in this field, It is also the first batch of blockchain entity application pilots who work in full accordance with the national requirements

all of us are in control of the future of bitlight. If Han didn't make bitcoin by faith a few years ago, how can he hold the future of bitcoin today

always believe Mr. Han's words and lead a group of like-minded people to build a second bitcoin. I hope this is not only Mr. Han's dream, but also the common dream of our bitlight family!!!
7. Many people have a misunderstanding that bitcoin is a blockchain, which is actually very wrong. Bitcoin is just an application of blockchain technology. Comparing blockchain to the Internet, bitcoin is just one of the apps, and the application scenario of blockchain is still very large. It is recommended to study and invest on the okex platform. Here is a tutorial for newcomers. I hope my answer can help you, take it
8. Looking at the operation process of blockchain from a transaction:
in bitcoin blockchain, when a transaction is generated through a node or wallet, it needs to be transmitted to other nodes for verification. The method is to encrypt the transaction data by digital signature and obtain a unique hash value representing the transaction by hash algorithm, and then broadcast the hash value to other participating nodes in bitcoin blockchain network for verification. Hash algorithm is to map any length of binary value to a fixed length of smaller binary value, then the smaller binary value is called hash value. Hash value is a unique and compact numerical representation of a piece of data. If you hash a piece of plaintext and change only one letter of that piece, the subsequent hashes will proce different values. It is computationally impossible to find two different inputs hashed to the same value
when a new transaction is generated, it will be broadcast to other participating nodes in the blockchain network first. Each node will put several new transactions into the block, and each node will collect several unverified transaction hash values into the block. Each block can contain hundreds or thousands of transactions
each node calculates the workload proof to decide who can verify the transaction, and the node with the fastest result will verify the transaction, which is a consensus approach. The node that obtains the verification right will broadcast the block to all nodes, and the node that completes the pow the fastest will broadcast its block to other nodes. Each node verifies and connects the new block. Other nodes will confirm whether the transaction contained in this block is valid. After confirming that it has not been repeatedly spent and has a valid digital signature, they will accept the block. At this time, the block will be formally connected to the blockchain and the data cannot be modified. Once all nodes accept the block, the block that did not finish the pow calculation will be invalid, and each node will rebuild a block to continue the next POW calculation
it can be seen that the principle of blockchain is not complicated, and its wide application is natural. Many companies have achieved fruitful results in the process of applying blockchain principles to reality. Like bitcoin, although the ID of the participant is anonymous, the data on the blockchain is public by default. The advantages brought by this openness are unprecedented, such as the ability to resist attacks, the ability to resist the autocratic system of capital control. It is open and transparent while ensuring security, and the account balance of all participants and all transaction records can be seen by people. Until now, we are still surprised by this, because this security method is so novel. However, in the seven-year history of bitcoin, no one has broken this security practically.
9. Bitcoin and blockchain are not the same thing. Blockchain is a distributed accounting technology, and bitcoin is a point-to-point form of digital currency, but bitcoin uses blockchain as its underlying technology.
10. Many people have a misunderstanding that bitcoin is a blockchain, which is actually very wrong. Bitcoin is just an application of blockchain technology. Comparing blockchain to the Internet, bitcoin is just one of the apps, and the application scenario of blockchain is still very large. It is recommended to study the blockchain business revolution of gojoy blockchain online university in qianchat or Himalaya, which is very thorough and easy to understand!
