What is the utilization rate of 2016 blockchain
The following are the reasons why 2017 will be the most critical year for blockchain:
the lasting value of bitcoin
bitcoin, the initial tool of blockchain, ended 2016 with a high profile, which is a good omen
just after the new year, fortune reported that
"after the prosperity of 2016, the price of bitcoin has reached $1000, which has increased by 120% since the beginning of this year, and recently reached the highest point in three years. The reasons, including the devaluation of RMB, the risk of China's currency control and geopolitical instability, have been considered as the key factors for the success of cryptocurrency. Another reason for bitcoin's landmark year is its staying power - the longer it stays, the more familiar it will be, and more like a real store of value. "
whether it is fair or not, the feasibility of blockchain technology is always closely related to the performance of bitcoin. If the decentralized database can succeed in the financial field, it can also be widely used in other places. According to convention, the healthy development of digital currency has triggered a discussion on how to integrate blockchain into new areas. With healthy bitcoin, blockchain can expand rapidly in other fields
existing participants
of course, this has existed for some time, because the blockchain has been firmly bound to bitcoin. Over the years, many groups have invested a lot of money to apply the technology to a wider range of areas, while adding new features and creating new applications. If 2017 is a great year for blockchain, these existing players must be ready to grow with it
this trend is marked by the addition of 8 new members to the hyperledger project before the end of 2016. Software company CA technologies, blockchain project factcom foundation, healthcare alliance hashed health, Korean koscom, accounting company ledgerdomain, trade ecosystem developer lykee, sovrin foundation and telecom company Swisscom all joined in the project
Thehyperledger project has entered 2017 with an eye-catching membership list, and plans to introce blockchain feasibility case studies in actual use cases
new investment
the sign that the technology will make progress this year is that companies all over the world have laid the foundation for using blockchain status. Companies around the world applied for or accepted 356 patent applications related to blockchain or digital currency in November last year, almost double the number in the first month of 2016, according to the report of blog technology
Marc Kaufman, financial technology intellectual property expert at Reed Smith, told blog:
"we have witnessed an exponential growth in the number of patent applications, and we expect to see thousands of blockchain patents in the next five years."
the company is submitting patents in such a rapid way because the blockchain has finally achieved its goal from Utopia to digital ledger tool. With the increase of the number of patents, the new discovery of the index blockchain will enjoy wider legitimacy in 2017
it is only time to know the development trend of blockchain in 2017, and vice versa. However, it is obvious that the status of blockchain technology can be seen by all, which also proves the expectation of early investors for its potential and may develop new potential in the future
blockchain has also become a hot topic in the financial sector in China, and all major domestic financial institutions have tested blockchain projects. China Post and IBM have jointly developed a set of blockchain asset custody system; Puyin group launched the tea based digital currency Puyin
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.
(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 is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block. In fact, the original English version of bitcoin white paper [1] does not use the word blockchain, but uses the word chain of blocks. In the earliest Chinese translation of bitcoin white paper [2], chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.
According to the report, based on the logic of equality and trust, blockchain tries to realize the security trust mechanism of "mutual trust" instead of "public trust" through technology with the characteristics of decentralization, non tampering and anonymity, and has graally become an important role in the field of fintech
the report also said that the open and tamperable properties of blockchain technology have the potential to change the financial infrastructure, and all kinds of financial assets can be integrated into the blockchain ledger to become digital assets on the chain, which can be stored, transferred and traded on the blockchain, making it a broad application prospect in the financial field
to put it simply, blockchain is similar to an account book, recording all the transaction information of bitcoin. This ledger is stored on each bitcoin node of the Internet, and each node has a complete backup. The ledger is stored in blocks, and each block contains some transaction records. Each block will record the ID of the previous block, forming a chain structure, which is called blockchain. When you want to initiate a bitcoin transaction, just broadcast the transaction information to the P2P network, record your transaction information as a new block and connect it to the blockchain, and the transaction is completed
to sum up, the biggest feature of blockchain is decentralization. There is no centralized hardware or management organization in the whole network. The rights and obligations of any node are equal, and the damage or loss of any node will not affect the operation of the whole system
the second feature is distrust. There is no need to trust each other in the data exchange between each node in the whole system. The operation rules of the whole system are open and transparent, and all data contents are open. Therefore, within the specified rule range and time range of the system, nodes can not and cannot cheat other nodes
the third feature is to break the information asymmetry. Blockchain's ledger technology will reflect all the information, similar to an open and transparent credit system of the whole society, breaking any asymmetric information in all societies
these three features alone are enough to make blockchain overturn our present life. The financial instry is one of them
Introction to Bubi blockchain
since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely
for example, our common inter-bank clearing systems, securities settlement institutions and various financial settlement systems are based on this principle, but the difference is that these settlement systems are centralized, that is, there is a central server or central institution to complete the settlement work. If the central institution database is damaged, the whole settlement will go wrong. The settlement system of bitcoin is decentralized and built on the network. We call it P2P network. It is a decentralized settlement database. The destruction of indivial database nodes does not affect the whole bitcoin settlement network at all. Therefore, the distributed data settlement network based on P2P network is a new financial innovation
blockchain technology concept stock? Blockchain is like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry. According to the forecast, by 2025, 10% of the relevant information in the global GDP will be saved by blockchain technology. Blockchain technology is facing a blue ocean, and related concept stocks are becoming the wind. In A-share listed companies, it is suggested to focus on the concept leading stocks: Feitian integrity, Yuyin shares. In the future, with the fermentation of speculation, other concept stocks are expected to follow suit
blockchain stock? Blockchain technology concept stock? The part of stock trading is very simple, but the process of clearing and settlement becomes complicated. Blockchain trading can greatly simplify this part of trading
the convenience brought by blockchain is reflected in the stock cash transaction, which mainly reces the time of clearing and settlement process. Specifically, it means to rece or eliminate the wrong transactions, improve the efficiency of the back office, and rece the settlement time.
