How to see Baidu blockchain
blockchain is a kind of technology, which solves the core "trust" problem in the market economy and reces the trust cost between strangers to a very low level
there is one crucial thing in the market economy, which is "trust". Without trust, no deal can be established. When you go to LAICHANG to buy vegetables, if you don't believe that the pesticide content in vegetable is up to the standard, you won't trade with that dealer; If you buy a bottle of water in a small shop, the clerk will not sell you the water if he doesn't believe that the money you give is real
the traditional small-scale peasant economy is acquaintance economy, and the transaction scale is limited to people who are familiar with each other nearby. If an acquaintance deceives you, he will lose your social relationship and damage his reputation in the whole circle of acquaintances. We believe that acquaintances are less likely to cheat us than strangers
therefore, once we are beyond the scope of acquaintances, we need to use a high cost to identify whether a stranger will cheat me and how to avoid the risk of being cheated. This situation will hinder the transaction and restrict the transaction
in addition, different races, nationalities, cultures, religious beliefs and so on will naturally have this kind of trust problem
in the market economy, why can there be so many transactions between strangers? Because of the birth of a new mechanism to solve the problem of trust in strangers
so far, the most important mechanism to solve the trust problem is the "trust intermediary" organization and mode
as long as you and strangers trust a third-party organization, the trust problem between you can be solved through this third-party organization
this third-party organization, we call it trust intermediary. Both the government and the bank are trust intermediaries
you can sell the goods you have worked hard to proce to a stranger in exchange for a stack of RMB banknotes. It's because the credit of the note issuing bank and the guarantee of the authority of the government guarantee the currency value and effectiveness of the banknotes. Otherwise, sell things, in exchange for a few ordinary paper, who would like to
in the era of global village and Internet, the people who buy your things may be strangers who will not meet and thousands of miles away. Trust is lower, so Alipay assumes the role of trust intermediation. Buyers first pay the goods to Alipay's account. When they receive the goods, they confirm that they are OK, then they agree to sell the goods to the seller. Taobao and other e-commerce have been booming rapidly in just over ten years
trust intermediary is in a central position in the transaction system. All transactions should solve the trust problem through it
However, the cost of trust intermediary itself is often hugeas a trust intermediary, how much transaction tax does the government charge each year? What is the most profitable instry? Financial services. The annual profits of Alipay's ant suit are over ten billion. p> What does this mean? Both sides of the market actually pay a huge trust cost
if there is any way to cancel or greatly rece the trust cost, the transaction cost of the general public can be reced, and the profits can be greatly increased
so in the Internet era, blockchain technology is on the stage
it allows the trading party to get rid of the intermediary, solve the problem of trust among strangers, and greatly rece the cost of trust
the blockchain can be expanded on a large scale, the data is open and transparent, the data of each client is consistent, and even if some clients are destroyed, the data security will not be affected. These highly reliable technical features can solve the trust problem of strangers with low cost
this technology can be extended to all fields that can be digitized, such as digital currency, payment and clearing, digital bills, proof of rights and interests, credit reference, government services, medical records, etc
in the medium and long term, blockchain will be a revolutionary technology, which will bring about great social changes like the existing Internet, and has great investment value and money making opportunities
in the future, the companies that can combine blockchain with different scenarios to promote applications may be the next group of bat, the next Google, Microsoft and apple
as the first practical application of blockchain technology, bitcoin has been widely accepted and used all over the world. Millions of users and tens of thousands of merchants have accepted the payment of bitcoin as a digital currency, and the exchange value of bitcoin as a currency is growing. Even e to the consensus that the total amount is fixed and the long-term value is bullish, bitcoin has become a hedge asset similar to gold, and the price has skyrocketed
blockchain technology has three obvious characteristics: openness, security and uniqueness
openness mainly refers to that the stored information in the blockchain is completely open to all participants. This is mainly determined by the point-to-point network storage mode of the blockchain. In the blockchain network, each node can store a of the blockchain, and the uniqueness of the blockchain can ensure that the is exactly the same between different nodes
security mainly refers to that the information stored in the blockchain block is saved after being processed by digital encryption technology, and only the private key holder can decrypt the information to obtain the real information. Other members can only see and verify the integrity and uniqueness of information, but cannot see the real information
uniqueness is mainly e to the fact that the information on the blockchain cannot be tampered with once it is on the chain, so it is unique. Of course, the uniqueness here also includes the uniqueness in space, that is, all nodes have only one version of information, and also includes the uniqueness in time, that is, the historical data cannot be changed. This uniqueness also means that the blockchain maintains the characteristics of a unique main chain in the process of operation, and once other chains appear, it is a bifurcation. The emergence of bifurcation will lead to the plication of blockchain in two different spatial dimensions. Of course, to solve this problem, we need to set reasonable consensus rules to avoid
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
the network itself has a large number of users, and the technology can certainly keep up with it. As for how, I don't know
The relevant certificates can be issued online for the data of blockchain storage and network forensics through easysaving. Through the record number on the certificate, the blockchain query can be concted directly through the official website of easysaving and relevant arbitration commission, including the preservation subject, preservation time stamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information
1) if it's just "blockchain", the direct network can find a good interpretation of "blockchain network"
2) if it is "blockchain technology", the network also has a good interpretation, and all walks of life are also trying to combine with blockchain technology in new fields. Maybe in the future, blockchain technology will be used correctly instead of being used to deceive people
3) if it is "blockchain information", you can go to all kinds of blockchain media or financial media, and almost every day there are relevant blockchain instry information and news reports. Such as: Babbitt, coin you finance, blocknet, golden, daily, etc
4) if it's "blockchain audio", you can go to Himalaya FM, litchi micro class, qianchat and other platforms. For example, the audio related to "voice of money", "Yu Lingxiong", "Wang Feng" and some other financial media blockchain is also good, with various dry goods and in-depth analysis
therefore, the above four points are all related to blockchain. It depends on your choice.

battery manager will give full play to the powerful performance of CPU and improve the fun of playing games.
in a narrow sense, blockchain technology is a decentralized shared general ledger that combines data blocks into a specific data structure in a chain way according to the time sequence, and encrypts and cannot be tampered with or forged. It can safely store simple, sequential and verifiable data in the system. Compared with traditional technologies, blockchain has the following advantages:
1. It is difficult to tamper with and more secure. The data recording mode of blockchain makes it very difficult to modify a certain data by changing all subsequent data records. The stable operation of bitcoin database with a market value of over 100 billion US dollars under hacker attacks can prove this
2. High reliability. If a node of the blockchain encounters network problems, hardware failures, software errors or is controlled by hackers, the system and other participating nodes will not be affected, so as to ensure that the overall network will not be affected when problems occur in some parts
3. Smart contract, automatic execution. Smart contract is a computer program running on a reprocible and shared account book. It can not only be executed automatically, but also be a participant in the system. You can think of it as an absolute trusted person, responsible for the temporary custody of your assets, and strictly in accordance with the agreed rules of operation. Smart contract has the advantages of transparency and trustworthiness, automatic execution, mandatory performance and so on
4. Network direct cooperation mechanism, more transparent. Blockchain connects the participants in an equal way, and the responsibilities of the participants are clear.
