6. Tmall double 11
ant blockchain uses blockchain technology to trace the origin of tmall double 11.15 billion commodities
community blockchain represented by bitcoin; It is also called alliance chain, which means that the nodes participating in the blockchain are selected in advance, and there are usually good network connections and other cooperative relationships between the nodes; Community blockchain is a practical application scenario of the combination of blockchain and physical goods, such as Domenech jewelry's Maobei mode
(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
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 focuses on keeping accurate records, authentication and execution, while AI helps to make decisions, evaluate and understand certain patterns and data sets, and ultimately proces autonomous interaction. AI and blockchain share several characteristics, which can ensure seamless interaction in the near future. Three main features are listed below
1. AI and blockchain need data sharing
distributed database emphasizes the importance of data sharing among multiple clients on a specific network. Similarly, AI relies on big data, especially data sharing. The more open data available for analysis, the more accurate the prediction and evaluation of the machine, and the more reliable the generated algorithm
2. Security
when dealing with high-value transactions on the blockchain network, there are great requirements for the security of the network. This can be implemented through existing agreements. For artificial intelligence, the autonomy of the machine also needs high security, in order to rece the possibility of catastrophic events
3. Trust is a necessary condition
for any widely accepted technological progress, there is no greater threat than the lack of trust, and artificial intelligence and blockchain cannot be ruled out. In order to make the communication between machines more convenient, we need to have an expected trust level. In order to execute certain transactions on the blockchain network, trust is a necessary condition
the impact of blockchain and artificial intelligence on ordinary people
in short, blockchain is a community-based technology, which can make value exchange more secure. Blockchain is just like its name. Each block contains an encrypted transaction record. The blocks are arranged in chronological order, and the security is guaranteed by a cryptographic system. Blockchain is a technology that can change rules, and its emergence is a revolutionary innovation
there are many functions of blockchain, and the specific application is also very wide. For example: if blockchain is used in the food instry, people will no longer worry about eating harmful food. If blockchain is used for diamond proction, consumers will no longer have to worry about buying fake diamonds. If the blockchain is used in the ecation instry, intellectual property protection can be strengthened. If the blockchain is used in the insurance instry, it can alleviate the information asymmetry of the insurance business and help to improve the security of the insurance business
the impact of blockchain and artificial intelligence on ordinary people is enormous. Just imagine, if blockchain and artificial intelligence are combined, will their role expand? Yes, the combination of the two can really have more impact to change the lives of ordinary people
blockchain and artificial intelligence are two extremely important roles in the field of technology, which bring convenience to our proction and life. If we find an intelligent way to make them work together, the impact of their interaction is unimaginable. This is also the core of OMT. After the combination of these two technologies, the future application scenarios are revolutionary and exciting. In the new ecological construction, data storage, sharing mechanism, platform problems, security problems, etc. can be overcome by using each other's technologies. OMT will create maximum value for global users and enterprises and bring more convenience to ordinary people through blockchain + artificial intelligence technology
the answer is over, hope to adopt, thank you!
the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode
2 - blockchain technology has a flexible architecture
according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions
the openness of 3-chain technology encourages innovation and collaboration
through the opening and cooperation of source code, blockchain technology can promote the cooperation among different developers, researchers and institutions, and learn from each other, so as to achieve a more efficient and secure solution
jinwowo will use blockchain technology to fully record big data sources and improve storage.
