1. A special database technology, which is based on elliptic curve digital signature algorithm in cryptography to achieve decentralized P2P system design. But the role of blockchain is not limited to bitcoin. Now, when people use the word "blockchain", sometimes it refers to data structure, sometimes it refers to database, sometimes it refers to database technology, but no matter what the meaning is, it has no inevitable connection with bitcoin
from the perspective of data: blockchain is a kind of distributed database. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data (that is, it is collectively maintained by system participants). In short, blockchain can realize distributed recording of global data information (which can be collectively recorded by system participants rather than centralized recording by a centralized organization) and distributed storage (which can be stored in all nodes participating in recording data rather than centralized storage in centralized organization nodes)
from the perspective of effect: blockchain can generate a set of time sequence, tamper proof and trustworthy database, which is decentralized storage and data security can be effectively guaranteed<
the working principle of blockchain technology
today's blockchain technology can be summarized as a technology to collectively maintain a reliable database through centralization and de trust in the past. In fact, blockchain technology is not a single and brand-new technology, but the result of the integration of a variety of existing technologies (such as encryption algorithm, P2P file transfer, etc.), which are cleverly combined with the database to form a new way of data recording, transmission, storage and presentation. In short, blockchain technology is a technology that everyone participates in recording and storing information. In the past, people entrusted the work of data recording and storage to the centralized organization, while the blockchain technology allows everyone in the system to participate in the data recording and storage. Under the distributed peer-to-peer network without central control point, blockchain technology uses the method of distributed collective operation to build a P2P self-organizing network. Through the complex verification mechanism, the blockchain database can maintain the integrity, continuity and consistency. Even if some participants commit fraud, the integrity of the blockchain cannot be changed, let alone tamper with the data in the blockchain
the source of blockchain technology principle can be summarized as a mathematical problem: Byzantine general problem. Byzantine general problem extends to Internet life, and its connotation can be summarized as: under the background of Internet, when we need to exchange value with unfamiliar opponents, how can we prevent people from being deceived and confused by malicious saboteurs, so as to make wrong decisions. The Byzantine general problem is further extended to the technical field. Its connotation can be summarized as: in the absence of trusted central nodes and trusted channels, how to reach a consensus among the nodes in the network. Blockchain technology solves the well-known Byzantine Generals Problem - it provides a way to create consensus networks without having to trust a single node<
Application of blockchain technology
blockchain technology overlaps three fields:
1, currency: issuance mechanism, distribution mechanism, adjustment mechanism
2, contract: equity, mutual insurance, right registration and transfer, smart contract, etc.
3, Governance: identity authentication, health management, notarization, judicial arbitration, decentralized autonomous organization, Voting, etc.
blockchain is like a "trust creating machine". What Bubi blockchain needs to do is a new technology and proct to realize real value circulation and make the Internet reach a new height
when it comes to blockchain technology, we have to mention bitcoin. Many people know that electronic currency bitcoin is not issued by a specific monetary institution, but generated by a large number of calculations of a specific algorithm. In fact, the core of real support for bitcoin is blockchain technology
How can invisible and intangible bitcoin operate through blockchain technology? The popular interpretation in the instry is that blockchain can be seen as a technical solution to collectively maintain reliable databases through "decentralization" and "distrust". Generally speaking, this technology can be understood as the technology of all participants in bookkeeping. In the past, people used a centralized server for bookkeeping. In the blockchain technology system, everyone can participate in bookkeeping and jointly identify the authenticity of records
"through this technology, even if there is no neutral third-party organization, the two sides who do not trust each other can cooperate. In short, blockchain is like a "trust creating machine."“ Blockchain technology is widely used in the era of big data. " At present, in addition to the field of Internet finance, blockchain technology has been applied in many fields and has shown great prospects
in addition, blockchain technology is also of great significance in law. Especially in the field of assets, whether it is physical assets such as real estate and automobile, or intangible assets such as health and reputation, we can use this technology to complete registration, transaction and tracking. It can be said that blockchain technology will be useful in any field of proction and life that lacks trust. "
blockchain technology concept stocks
it is recommended to pay attention to it manufacturers with blockchain technology and applications. We think that blockchain is more like a mechanism or technical solution. In the future, manufacturers who can combine this mechanism into different scenarios for promotion and application are expected to achieve subversive success. Blockchain technology can ensure that the data structure will not be tampered and forged, and has broad application prospects in the field of financial payment. Bubi blockchain has set up a special team around digital currency, focusing on the development trend of digital currency for a long time, and has set up a special team to carry out relevant work around the instry development demand of digital currency, including the research on blockchain technology.

2. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology or a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book, because the account books of all nodes are consistent, and different nodes can trust each other, so there is no doubt about the data, So we all say that blockchain realizes trust technically
based on trust, bumeng has built a digital asset platform, which allows enterprises to issue their own assets. In fact, it is an exploration based on the characteristics of blockchain technology to let these assets circulate freely.

3. The entry threshold of virtual currency is the lowest, which is relatively reliable. Choose regular exchange hot currency or okex. Leverage trading of foreign exchange futures is very risky. The stock market is not perfect and has little investment value at present.
4. What is blockchain technology
before discussing how to apply blockchain in daily life, let's talk about what blockchain is and how it works
blockchain is an open distributed database, which is essentially a computer file used to store information (data)
the name of blockchain comes from its structural characteristics: the file is composed of data blocks, and each block is linked to the previous block to form a chain. Each block contains data, such as transaction records and records when the block was edited or created. Information (data) is stamped with time stamp, which is the origin of blockchain
it is crucial that, unlike centralized databases owned by companies or government agencies, blockchain is not controlled by any person or entity, and data is completely copied (distributed) on multiple computers
because it is a decentralized way to store and access data, it becomes extremely secure. Different from the centralized database, the attacker does not have a single entry point, so the data security is more guaranteed<
in addition to the two characteristics of decentralization and security, blockchain has become a leading technology which is different from other technologies:
tamperability: once entering the blockchain, any information can not be changed, even the administrator can not modify this information. It makes blockchain easy to audit
accessible: all nodes in the network can easily access information
no third party: blockchain can help point-to-point transactions, so whether you are trading or exchanging funds, you do not need the approval of a third party. Blockchain itself is a platform
the impact of blockchain technology
first, the open and tamperable nature of blockchain technology makes it possible to decentralize the trust mechanism. It has the potential to change the financial infrastructure. Various financial assets, such as equity, bonds, bills, warehouse receipts and fund shares, can be integrated into the blockchain ledger to become digital assets on the blockchain, which can be stored, transferred and used in the blockchain Deal. It has a broad application prospect in the financial field. For example, it has typical applications in cross-border payment, insurance claims, securities trading, bills, etc
Second, the current Internet of things ecosystem relies on the centralized network management architecture, and all devices are connected through the cloud server. With the expansion of the network scale, the infrastructure and maintenance of centralized cloud servers, large servers and network equipment will occupy a high cost
in the decentralized Internet of things, blockchain is a framework to promote transaction processing and cooperation among interactive devices, and each device on the network can operate as an independent and micro business entity< Third, public service is a factor to promote economic growth and social progress. The supply of public service has an important impact on various subjects, systems, cultures, attitudes and behaviors in the process of political, economic and social development. The traditional notarization relies on the government, and the limited data dimension and the historical data information chain that has not been established often lead to the government and schools unable to obtain complete and effective information. Using blockchain, tamper proof can be established. In the fields of digital rights, intellectual property rights, certificates and public welfare, new authentication mechanisms can be established to improve the management level of public services.

5. At present, many instries can carry out blockchain plus, which is a new hot technology. Just like the previous Internet, including public services, is also integrated with blockchain technology. Changsha high tech Zone has launched a SMIC blockchain service platform project, which is to apply the blockchain plus public service mode to all enterprises to collect information on the blockchain.
6. Don't give too much publicity to blockchain technology. To put it bluntly, it's a distributed accounting system. It's not a new technology. Without bitcoin, maybe people will never pay attention to it
7. Blockchain technology
