Baidu blockchain

1. Can search on the Internet, ah, this intervention program code

2. Since October, but the network gold mine is not based on blockchain technology, you can refer to the webpage link
to see what others say.

block chain is still in the very early stage. At

NPC and CPPCC sessions, Robin Li's speech focused on the open platforms such as PaddlePaddle, DuerOS and Apollo, and the automatic driving of the network. In addition to the Internet and technology, the big guy also talked about the issue of banning smoking related to life and environment, and proposed to carry out the promulgation of national tobacco control regulations

in October 2017, Internet Finance officially joined the hyperledger open source project of Linux foundation, and other core board members include IBM, Intel and JPMorgan Chase

Ma Yun: I want to know what bitcoin can bring to the society

at the two sessions, Ma Yun... Oh, sorry, Comrade Ma Yun who doesn't want to wear a red hat didn't attend the two sessions

then, let's review the comments made by Ma Yun when commenting on bitcoin:

"I'm not very interested in bitcoin. What I want to know is what can bitcoin bring to society? In other words, I think bitcoin technology is very powerful, but we have to be very careful with bitcoin. "

although Ma Yun was very cautious about bitcoin, he also said that he did not understand bitcoin. However, as for "bitcoin technology" or "blockchain", Ma Yun's view is "very powerful"

4. Now the blockchain is flying all over the world, and it's hard to tell whether it's true or not.
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

It is reported that the new network blockchain proct, Du universe, went online on the official website at 10:00 on June 8, and its app version will go online on June 13

in the space rule setting of "degree universe", there is a positive correlation between star gravity, mass of aggregated elements and star mass. When the star mass reaches a certain degree, it can "unlock" more mysterious functions

according to the official website of Du universe, this blockchain proct has not yet been fully formed. The official website also revealed that 100 elements will be airdropped on the first day of the launch

network, a blockchain proct, covers many fashionable elements such as "blockchain game", "uniqueness", "star crossing" and "decrypting the unknown", giving "curious players" more imagination under the wave of blockchain

6. Blockchain blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. The definition of supply chain is: around the core enterprise, from the supporting parts to the intermediate procts and final procts, and finally by the sales network to deliver the procts to consumers, it is a whole functional network chain structure from suppliers, manufacturers, distributors to the end users.

In the era of mobile Internet, the dividend is over, and the next stop is blockchain. On June 4, Xiao Wei, a network blockchain scientist, presented the new generation blockchain network operating system "super chain" of the network for the first time at the opening ceremony of the 2018 chain Valley lecture hall

the blockchain field ushered in a major event, that is, the network publishing super chain. Over the past few years, many enterprises have entered the field of blockchain. This network release of super chain is a solution to promote the development of blockchain, which is of great positive significance. This solution is also regarded as the network embracing the blockchain. What's more, the future is generally optimistic

the network once missed the opportunity of mobile Internet. The most obvious example is the tragic failure in the field of o2o. The network glutinous rice, which used to bet heavily, is now facing the situation of being trapped by hungry and meituan comments. The hopeless network will focus on artificial intelligence, hoping to pull back in the era of artificial intelligence

as everyone knows, in addition to artificial intelligence, there is also a revolutionary technology that is setting off a global upsurge, which is blockchain. And the network, never want to miss the chance to change their destiny again

8. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts
