『一』How do you evaluate the Postal Savings Bank of China’s introduction of blockchain?
The Postal Savings Bank of China announced on the 10th the launch of an asset custody system based on blockchain. The system was launched in October 2016 and has already executed hundreds of transactions in a real business environment. Postal Savings Bank President Lu Jiajin said that this is the first successful practice in China’s banking industry to apply blockchain technology to the bank’s core business system.
Lu Jiajin introduced that blockchain has been included in the national informatization plan and has been designated as a strategic frontier technology. The asset custody system launched by the Postal Savings Bank this time selects an asset custody business scenario in which five roles including asset entruster, asset manager, asset custodian, investment consultant, and auditor jointly participate, realizing the information sharing and asset management of the custody business. Monitoring of usage.
“Blockchain technology can solve the trust problem in financial activities at a low cost, will bring efficient exchange of credit to multi-party transactions, and has the potential to promote profound changes in the financial industry.” Lu Jiajin said that the Postal Savings Bank launched The blockchain solution enables real-time sharing of information by multiple parties, eliminating the need for repeated credit verification processes, shortening the original business link by approximately 60% - 80%, and making credit exchange more efficient. (Sohu)
Biying China, a digital currency crowdfunding platform, is also trying a new model of “blockchain + crowdfunding”.
『二』Why 2017 is the most critical year for blockchain
The following are the reasons why 2017 will be the most critical year for blockchain:
< p>Bitcoin’s Enduring Value
Bitcoin, the original tool for blockchain, ended 2016 on a high note, which is a good sign.
Shortly after the new year, "Fortune" reported,
"After experiencing a boom in 2016, the price of Bitcoin has reached $1,000, rising since the beginning of this year. up 120% until recently reaching a three-year high. Reasons including the depreciation of the yuan, the risk of China’s currency controls, and geopolitical instability have all been cited as key factors in the cryptocurrency’s success. Bitcoin’s iconic one Another reason for the year is its retention power - the longer it is, the more familiar it will be, and it will become more like a true store of value."
Whether it's fair or not, blockchain technology The feasibility of Bitcoin is always inseparable from the performance of Bitcoin. If decentralized databases can be successful in finance, they could be used more widely elsewhere. As is customary, the healthy growth of digital currencies has sparked discussions about how to integrate blockchain into new areas. With a healthy Bitcoin, blockchain can expand rapidly in other areas.
Existing Participants
Of course, this has been around for a while, as the blockchain has been firmly tied to Bitcoin . Over the years, many groups have invested heavily in making the technology more widely available, while adding newfunctionality and create new applications. If 2017 is to be a great year for blockchain, these existing players must be ready to grow with it.
A sign of this trend is that before the end of 2016, the Hyperledger project added 8 new members. Software company CA technologies, blockchain project Factcom Foundation, healthcare alliance Hashed Health, South Korea's Koscom, accounting firm LedgerDomain, trading ecosystem developer Lykee, Sovrin Foundation and telecommunications company Swisscom have all joined the project's top 100 list.
The Hyperledger project enters 2017 with an impressive roster of members and plans to introduce blockchain feasibility case studies in real use cases.
New Investments
In a sign of the progress the technology will make this year, companies around the world are laying the groundwork to take advantage of blockchain's status. According to Bloomberg Technology, global companies applied for or accepted 356 blockchain or digital currency-related patent applications in November last year, almost double the number in the first month of 2016.
Marc Kaufman, fintech intellectual property expert at Reed Smith, told Bloomberg:
“We are witnessing an exponential increase in the number of patent applications and we expect that in the next five years we will Seeing thousands of blockchain patents.”
Companies are filing patents at such a rapid pace because blockchain is finally moving from utopia to digital ledger tool, and the number of patents is increasing exponentially With the new discoveries of blockchain, blockchain will enjoy wider legitimacy in 2017.
Only time will tell what the development trend of blockchain will be in 2017, and vice versa, but it is obvious that the status of blockchain technology is visible to everyone, and it also proves that early investors have expectations of its potential, and that new potential may be developed in the future.
Blockchain has also become the darling of the financial community in China and has become a hot topic. All major domestic financial institutions have tested blockchain projects. China Post and IBM collaborated to develop a blockchain asset custody system; Puyin Group launched the tea-based digital currency Puyin.
『三』 What kind of technology is "blockchain"
What kind of technology is "blockchain" Blockchain is an important concept of Bitcoin The "2014-2016 Global Bitcoin Development Research Report" released by Huobi, Tsinghua University PBC School of Finance's Internet Finance Laboratory and Sina Technology mentioned that blockchain is the underlying technology and infrastructure of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin.Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Account book. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes automated Smart contracts are composed of scripts that program and compute data in a new decentralized infrastructure and normalize computing.
Domestic blockchain application platforms include an asset custody system based on blockchain technology jointly developed by the digital currency crowdfunding platform Biying China, China Post and IBM.
Blockchain is a decentralized, distributed ledger system participated by nodes. The data stored on it cannot be forged or tampered with, and is open to the public. Transparent, the information and value recorded by each account at any point in history can be found on the blockchain. The characteristics of the blockchain protocol provide the necessary foundation for the execution of smart contracts. The contract can be automatically executed and trusted according to established conditions without the need for auditing by any centralized organization.
Blockchain technology is the underlying core of the Bitcoin system. Its essence is a decentralized ledger. When people conduct transactions through the Internet, a new transaction will be recorded on the ledger, and this ledger is A decentralized ledger is jointly maintained by everyone on the network. People can see ongoing transactions at the same time, and control is not in the hands of institutions or individuals. Transactions cannot be tampered with or forged, and they will be permanently stored in the ledger.
For example, the Tongxin Huzhu blockchain mutual aid platform has four major characteristics in applying blockchain technology:
Openness and transparency
Openness and transparency, once all information recorded on the blockchain is recorded, it will be very It is difficult to tamper with and cannot be hidden, and users can check it at any time.
Democratic decision-making
Bottom-up decision-making, the blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decisions and jointly participate in major decisions.
Accurate execution of rules
Accurate execution of rules. The smart contract technology defined on the blockchain converts all rules into public and clear codes, which can be executed accurately and accurately. Once anyone is identified Cannot intervene.
Never downtime
Never downtime, the blockchain based on the public chain is not affected by any organization or individual. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist.
What is blockchain? Blockchain is a decentralized shared accounting technology that allows all parties involved to establish a trusting relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. Blockchain is still in its infancy. Many people have discussed with me how we can ensure both rights and privacy at the same time. Of course, we are just exploring now. We need fair content across the entire network and clear protection. This is what I can only say. So far, this is my arrangement for the future.
Blockchain concept? The idea of blockchain is to be completely decentralized and rely on decentralized justice. In that case, theoretically the cost will drop a lot, proving that real assets and property rights can directly correspond to each other on the Internet. It has solved the problems of decentralization and asset ownership that were not solved by the first generation of Internet information. How big a role does big data play in financial innovation now? Only by registering big data can we know who it belongs to. In fact, this has always been a problem that we cannot solve now. This is not a small problem. If there is a technology in the capital market that makes the property rights of things that were originally unclear clear, that will be a big problem for us. The entire market is undergoing a huge transformation.
What is blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanisms. This still cannot completely solve certain problems. To give a simple example when it comes to user privacy, I have a piece of data placed on the machine. The partner comes over and makes an insurance analysis to analyze the cooperation. There is a risk here. Or not, can we deal with it or clarify the property rights of the laboratory, and then clarify the processing rights and data rights. The common products produced by everyone are common to everyone. If we need to divide different things, how to price them and how to divide them? In addition to the technology of blockchain and a decentralized database, when it comes to the above mentioned tasks, it is another issue, and then there is the issue of pricing and the market mechanism. All fields have proven to recognize this rule, so this I think blockchain is a very good core technology, but it cannot cover all problems.
Introduction to Bubi Blockchain
Bubi Blockchain is mainly positioned to provide commercial-grade blockchain infrastructure services, which mainly includes building a blockchain system and building on top of the blockchain system. A support system with high expandability. On top of this support system are applications from all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, a team of more than a dozen people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi Blockchain chooses points has something to do with the market's promotion method. As we all know, blockchain is a technology that is very suitable for the issuance and trading of digital assets. Points are a digital asset that is naturally legal and compliant, and has a small impact because of its small amount. Therefore, it is a very suitable choice to use points as your first attempt at digital asset issuance. Issuing points based on the blockchain, for the circulation and interaction of pointsA swap can indeed be of great help.
What is blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to reducing property transfer costs, blockchain technology can also be applied to various fields involving company stocks, financial derivatives, and points programs of commercial institutions. The blockchain community is currently focusing on promoting the wider application of this technology in the field of financial assets. Relatedly, various platforms that are still under development have also received very considerable investment.
Blockchain concept? Structurally or by definition, these things are very different. The U.S. dollar, or any currency, from a typical definition, is primarily used as a medium of exchange or store of value for economic activities. Within the geographical scope where a certain currency circulates, people in the region reach a consensus on the use of this currency, making it convenient for everyone to use the same currency to purchase goods or services (the function of currency as a medium of exchange). There is a responsibility to manage the currency through monetary policy in order to ensure the preservation of the value of the currency and avoid the occurrence of inflation (the store of value function of currency). In today's world, almost everyone uses some form of currency in their daily lives.
What is blockchain? Even developers within the blockchain community often easily overlook the big picture mentioned above. There are many competitive projects in the blockchain community, and they are also full of various disputes about the evolution direction of blockchain technology. Over time, some projects in the community will be successful, and others will not be so lucky. Things will not always develop in the direction we expect, but no matter how these projects in the early blockchain community develop, one thing is very clear, that is, blockchain technology has brought us at least A revolutionary function: Blockchain technology will greatly reduce the cost of financial property transfer, and blockchain will be used to control, manage and transmit financial property.
What is blockchain? Blockchain concept? After a certain application analysis, we return to the starting point. The definition of this blockchain technology will surely become more and more abundant with the expansion of applications, and people will discover more mysteries of blockchain technology.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the basis for Bitcoin. underlying technology. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet information. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. The lightweight Bitcoin wallet uses online confirmation, which means it does not download the blockchain data to the device storage.
Many of Bitcoin’s altcoins also use the sameThis design is just slightly different in the workload proof and algorithm. For example, using proof of stake and SCrypt, etc.
Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “genesis block”.
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left an unchangeable sentence in the genesis block:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor Darling was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
With the blockchain’s timestamp service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service and store it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
Chongqing Jinwowo analyzed: Blockchain is actually a decentralized distributed ledger database.
How popular is blockchain technology?
Blockchain technology makes DAC possible. DAC is something that can fundamentally subvert the organizational model of human society. I believe that its impact on society will surpass the Industrial Revolution and become the most profound change that the Internet has brought to the world.
The essence of blockchain technology is a method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It replaces the current Internet with data blocks (Block). The road's reliance on the central server enables all data changes or transaction projects to be recorded on a cloud system, theoretically achieving self-certification of data during data transmission.
Blockchain technology can be applied to many industries:
Art industry
Ascribe allows artists to use blockchain technology to declare ownership, Issue numberable, 100% editions of your work in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
Legal Industry
BitProof is one of the many file timestamp applications that have emerged in recent years.The most advanced one will make the traditional notarization method a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property rights. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
Development Industry
Colu is the first company to allow other companies to issue digital assets. They can "tokenize" various assets and have a profound impact on many people. Although the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be configured in various states and types, and can leave and return to the system. , and when storing data on the blockchain is too large, the data can be stored on the BitTorrent network.
Internet Mutual Aid Industry
Tongxin Mutual Aid is the first blockchain online mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, it eliminates the shortcomings of the traditional online mutual aid model. Establish an open and transparent new online mutual aid platform.
Aite Cat is a virtual pet game produced under blockchain technology. This virtual cat is similar to Internet Letts Dog, 360 pet cat, and NetEase’s Planet are all the same type of blockchain virtual products. The difference between Aite Cat is that the entire cat design uses a 3D three-dimensional effect, making the cat’s The display is no longer a single picture, allowing the cat to move, which increases the fun of the cat.
What technology is the Huangbao blockchain system?The Huangbao blockchain is a powerful decentralized loop intelligence system. The Huangchain chain is referred to as HUANG. It is the first to be used in financial services, advertising media, games and entertainment, various life applications and other fields, becoming a blockchain 3.0 The representative virtual currency of the era, Media Chain 3.0 technology has the core characteristics of being safer, more efficient, more flexible, and more open. The widespread application of its technology will surely trigger new forms and new ideas in the global media industry, which can Create convenient services and new concepts, which marks a new economic era before the public.
『四』Digital currency platform development, what is digital currency
Digital currency platform development requires professionals to be responsible, but now that digital currency technology has matured, development difficulty has become It's very simple and has become a standardized technology. The current digital currency technology is no longer the highlight, the highlight is the application scenarios of this digital currency.
The birth and global popularity of Bitcoin relies on ideas. This idea is at the forefront of the times, but Bitcoin has already taken the lead and other digital currencies can no longer replace it.Although some altcoins later became popular for a while, they eventually slowly subsided, and only Bitcoin remained strong. Puyin took another shortcut and emerged as a standard digital currency, backed by related tea assets, and its value is recognized by society.
『Wu』 What are the companies that are relatively mature in developing blockchain technology?
Shandong Bianke Information Technology Co., Ltd. is a software development company with excellent technology.
[Blockchain Exchange]
Blockchain technology application research and development, exchange wallet system app development Blockchain technology is actually a new type of Internet. Why is it said to be a subversion of the Internet? Because the Internet solves the problem of information transmission, and the blockchain solves the problem of value transmission. Source Zhongrui Blockchain System Development Blockchain has many value transfers, such as distributed ledgers, decentralized trust, smart contracts, etc. So what kind of society will it build in the future?
The answer is: a distributed business and self-disciplined society. The first characteristic of blockchain is decentralization; no third-party intervention is required to realize person-to-person, point-to-point transactions and interactions.
Second, the information cannot be tampered with; once the data information is written into the block, it cannot be changed or revoked.
Third, openness and transparency; within a very short period of time, the block information will be copied to all blocks in the network to achieve data synchronization across the entire network, and each node can trace back all past transaction information of both parties.
Fourth, collective maintenance; in the entire blockchain network, all roles jointly maintain the reliability and security of the entire blockchain information.
Fifth, reliable database; only by mastering 51% of the nodes in the entire system can the blockchain information be tampered with. This is obviously impossible because there are many participants in the entire system and it is extremely costly to master so many nodes. It can't be achieved either.
The characteristics of blockchain bring great opportunities to the financial industry. Using it to transform internal application scenarios in the industry can bring three main benefits:
1) Reduce costs: communication Cost: Centralized trading markets generally require the participation and coordination of multiple parties such as central settlement systems, securities companies, exchanges, and banks. The coordination cost is very high. Through blockchain signature encryption and other technologies, information can be shared and coordination costs can be reduced; Operating costs: Reducing manual labor and paper vouchers, increasing automation through smart contracts, and centralized coordination also bring very high operating costs.
2) Improve efficiency: The settlement cycle is very fast. When the financial transactions realized through blockchain technology are confirmed, it is actually a settlement process that combines clearing, settlement and auditing. The openness, transparency and non-tamperability of the blockchain can save traces of operations, allow supervision records and audit traces to be retained, and facilitate supervision and auditing.
3) Risk reduction: Transaction confirmation on the chain completes clearing and calculation, greatly reducing transaction risks Blockchain technology application research and development, exchange wallet system app development
『Lu』Why blockchain has become a hot technology and topic
The most important of these may be that Bitcoin, launched on the basis of blockchain technology, has opened up a new relationship with traditional society (offline) The exploration and attempt of brand-new technologies and rule systems such as Internet user identity verification, wealth confirmation, transaction records, and notarization verification, which are not much related and are completely applied to the online world (online), provide people with the opportunity to adapt to the development of the Internet society. Alternative paths and unlimited imagination.
From its application in Bitcoin, blockchain is intuitively speaking, it combines encryption technology with the Internet to form a new set of data blocks (BLOCK) establishment, Bitcoin configuration, netizens Identity verification, as well as Bitcoin (value) confirmation formed by mining, Bitcoin transaction records, and extended encryption of Bitcoin cross-block flow (value transfer) (adding factors such as block and transaction time marks) registration and verification Including verification, etc., the Internet protocol rules and accounting (Ledger) system of block connection (Blockchain), full encryption, and mutual authentication.
Ant Financial has applied blockchain technology to public welfare; China Post has applied blockchain technology to its core business and launched an asset custody system based on blockchain technology; Puyin Group has applied blockchain technology to its core business. Chain Technology launched the tea-based digital currency Puyin, which has a great influence in the digital currency circle. Jubi.com also opened a special trading area for Puyin.
『撒』Why do banks love blockchain so much
Many problems remain to be solved when banks compete for blockchain
As traditional financial institutions, banks are The most active pathfinder in the blockchain field. In recent years, many domestic and foreign banks have applied blockchain technology to credit, clearing and other fields. The unique trust mechanism of blockchain is regarded by banks as a key technological breakthrough for innovative risk management and simplified transaction processes. However, as an emerging technology, the blockchain ecosystem is still in the process of being established, its applications are very limited, and many problems still need to be gradually solved during development.
“At present, the blockchain cannot run high-frequency and concurrent transactions, and the network speed and computing power cannot support it. For example, in the payment field, if it is online shopping, it can still be achieved; if It’s high-frequency trading in futures, so it can’t be done,” Huang Zhen said.
Jiang Peng said that at the beginning of designing the blockchain system, CITIC Bank carefully demonstrated the business links suitable for using blockchain.
“From global experience, it is not suitable to use blockchain to build large and complex systems. Don’t try to use blockchain to solve all problems, but focus on solving core problems. Do too much Complex systems are time-consuming, and technology develops so fast that before the old system is completed, it will face iterations of new technologies," Jiang Peng said.
The idea of "only solving core problems" ensures that after the blockchain is launched, the relevant business operations of CITIC Bank branches can achieve business upgrades without process modification.
Fan Bin admitted that it will take time for banks to fully apply blockchain, IBM’s investment in the blockchain open source community will continue, on the one hand to cultivate the market, and on the other hand to compete for the commanding heights of the blockchain platform. With the rapid iteration of blockchain technology itself, there is still a lot of room for imagination in the scenarios in which financial institutions can use this new technology.
