❶ How to understand the consensus algorithm pbft in IBM blockchain technology hyperledger-fabric in a popular way
1. What is the technology of blockchain? If we assume that the database is This account book, reading and writing the database can be regarded as a kind of accounting behavior. The principle of blockchain technology is to find the person with the fastest and best accounting within a period of time. This person will do the accounting, and then the ledger will be recorded. This page of information is sent to everyone else in the entire system.
❷ IBM launches a blockchain pilot to simplify the bank guarantee process
Technology giant IBM launched a pilot of a blockchain platform aimed at simplifying the bank guarantee process.
In a press release shared with Cointelegraph on July 3, IBM said the pilot was launched in partnership with four Australian financial services companies.
The pilot, called Lygon, is backed by IBM, Australia and New Zealand Banking Group Ltd, Commonwealth Bank, property operator Scentre Group and Australia's first bank Westpac. Starting from the 4th, the pilot group’s retail property leasing customers will have a trial run for eight weeks.
Essentially, Lygon is a blockchain-based platform that digitizes the issuance and management of bank guarantees in the retail property leasing sector. According to the release, digitizing processes will reduce the risk of fraud, reduce potential errors, and increase transparency and security.
Once the pilot is complete, Lygon plans to expand the range of digital bank guarantees it supports and start offering these guarantees to other industries. Didier Van Not, general manager of corporate and institutional banking at Westpac, said: “We have created a blockchain-based platform to digitize the bank guarantee ecosystem. The pilot will use The distributed ledger is tested on real-time transactions to prove that the technology is commercially viable. This is a great example of digital transformation that improves customer experience."
So far, IBM has Many enterprise blockchain products have been launched. Last month, Brazilian bank and financial infrastructure service provider CIP officially launched a blockchain ID platform using Hyperledger Fabric in partnership with IBM. Its goal is to verify digital signatures using mobile devices.
In March this year, five Japanese banks collaborated to launch a financial services infrastructure based on IBM's distributed ledger technology.
❸ IBM Walmart applies blockchain technology to prescription drug tracking
IBM, KPMG, Merck and Walmart are joining forces with the FDA to create a proof-of-concept blockchain network. this projectLinked to the U.S. Drug Supply Chain Security Act, it is intended to help the FDA and other organizations in the drug supply chain develop a blockchain network to identify and track the distribution of prescription drugs.
As the blockchain famous saying goes: it builds trust when you need it most! Mark Treschuk, head of global solutions at IBM, said blockchain could provide an important new approach to further improve trust in the biopharmaceutical supply chain. Blockchain technology can not only provide an audit trail to track drugs in the supply chain, but also track who shares data and who shares it with whom, without revealing the contents of the data itself. Blockchain therefore has the potential to change the way drug data is controlled, managed, shared and acted upon throughout its lifecycle.
IBM has been committed to the research and development of blockchain technology in recent years, and has been applied in fields such as shipping, food, banking and hard drives. In 2016, Walmart partnered with IBM to apply new food safety to its suppliers, applying blockchain technology to achieve traceability throughout the food supply chain. In addition, IBM and Maersk have formed a joint venture focusing on global trade, aiming to create a blockchain platform to serve trading partners around the world.
China is also establishing new standards for food supply chain safety, relying on the eyes of IBM, Walmart, JD.com and Tsinghua University to use blockchain technology to collect data on the origin, safety and authenticity of food.
The widespread application of blockchain technology will change people’s lives. From wearables to food, it changes people’s understanding of ordinary things. After applying blockchain, ordinary items will be redefined, and consumed items will not disappear out of thin air. Blockchain technology will make a world defined by matter. , truly becomes a digital world, and every seed that disappears on the earth will be remembered forever!
❹ Blockchain financial application
Blockchain financial application is a key area where it plays a role in reality. The financial industry needs such high-end technology, and the traditional operating methods will be affected by Such technology has undergone profound changes. Blockchain financial applications have many distinctive features, and people are talking about them. It has attracted more and more attention because of its actual effects, and has had an increasing impact.
Abstract: Developed countries and technology companies have taken the lead in the research and application of blockchain technology. Judging from the application of patent technology, there may be a gap of about one and a half years between my country and the United States in blockchain technology. Based on the above situation, how can China achieve "asymmetric" catch-up? The first thing is to see the situation clearly, seize opportunities and meet challenges. Secondly, after understanding the necessity of the underlying construction of blockchain for the existing business and future development of the financial industry, a consensus was reached among various financial companies to establish a "China's Financial Blockchain Alliance". The last step is to advance collaboratively and embrace change.
How to understand blockchain?
Bitcoin: A peer-to-peer electronic cash system. In 2009, after the paper was published, Bitcoin was born as a virtual currency in the digital world of the Internet. At present, the total market value of Bitcoin is about US$6.5 billion. Although the market value is constantly changing, it is still the largest virtual currency in the world.
Another important concept is blockchain. Blockchain is an underlying technology of Bitcoin, and Bitcoin is just an application of blockchain. As we all know, Bitcoin can realize point-to-point value transfer. In addition to the Bitcoin blockchain, there are many other blockchains, such as the Ethereum blockchain, etc. Therefore, we should distinguish between concepts such as Bitcoin, Bitcoin blockchain, blockchain, and blockchain technology.
Currently, people have several misunderstandings about blockchain. Blockchain can be described in English as "Decentralized Blockchain", where Decentralized is translated as "decentralized". However, I think the blockchain has realized the unintermediary dissemination of value, which is point-to-point value dissemination. This does not mean that after entering the blockchain era, there is no need for a center, but that it should move from a single centralization to a center and a center. parallel development. Then, the existing center is likely to become a branch center or a weak center. At present, all banks have their own data centers. If a financial blockchain alliance is established in the future, they can become nodes in the blockchain alliance, so blockchain does not require a center.
Blockchain does not require credit
We often see some articles that believe that blockchain needs to “remove credit”. In fact, blockchain relies on consensus The algorithm builds trust and ensures the correctness of transactions through consensus among nodes. Build trust at low cost through mathematics and algorithms instead of "removing credit". However, digital asset transactions between people do not require two people to know each other or have a trust relationship with each other, nor does it require a third-party credit agency. It only requires everyone to trust the trusted network of the blockchain.
Why is it considered credible? Because it is a distributed database, it has a consensus-based mechanism: a set of encryption algorithms, making it immutable. On the one hand, the public key makes information transparent and traceable; on the other hand, the private key can protect privacy.
Blockchain is not a mature technology, nor is it omnipotent. Blockchain technology is still in its early stages of development. At the beginning of this year, we sent a delegation to Barclays South Africa’s blockchain research laboratory to study. During the seminar, Barclays African blockchain experts believed that it will take at least five to ten years for blockchain technology to become a truly mature technology. At present, blockchain has the disadvantages of relatively slow computing speed and small storage space. Moreover, not all data processing requires the use of blockchain.
Research and application of blockchain in foreign countries
We found that the established financial developmentDeveloped countries have taken the lead in researching blockchain technology. The British government believes that it is very important for the government to participate in the legislation of digital currencies and blockchain networks, and the government encourages in-depth research on blockchain technology. The British government is actively evaluating the potential of blockchain technology and considering its use to reduce financial fraud and reduce costs. In addition, the UK government plans to develop application systems that can be used between government and public agencies.
In February this year, the European Commission placed cryptocurrency at the top of the list of rapid development target areas. This initiative promoted policy research on digital currencies by various agencies. Technology companies are also leading the way in research on blockchain technology.
IBM launched the "Open Ledger Project" to develop an enterprise-level blockchain software structure and promote the commercial use of blockchain technology through the Bluemix and API foundation of the IBM cloud computing platform. Architecture to support the docking of external data. IBM still has a lot of practice in blockchain technology. Recently, it and a company in South Korea conducted creative experiments using blockchain technology and the Internet of Things, and achieved some results.
Microsoft uses the Azure platform to provide users with "blockchain as a service", which can enable R3 and its bank members to speed up the experiment and learning process, and accelerate the development, testing and deployment of distributed ledgers.
Intel also released SawtoothLake, an efficient modular platform for building, deploying and running distributed ledgers; at the same time, Intel is also studying to create a trusted execution environment for hardware chips for blockchain applications, providing Greater security and privacy.
Meanwhile, Wall Street is also taking action. Although founded relatively late, R3’s core function is to formulate industry standards for the development of blockchain technology in the banking industry, as well as explore practical uses and establish a blockchain alliance for banks.
From what we know, in addition to these two new companies on Wall Street catering to the digital financial era, large financial institutions are studying blockchain technology and building their own areas. Blockchain concept and technology team.
Currently, blockchain technology already has practical application cases.
In Canada, the blockchain startup company "Blockchain Tech Ltd" has successfully been listed on the Toronto Stock Exchange GEM; the Estonian government will launch the government's blockchain medical insurance Record.
Domestic attention and research on blockchain technology
Blockchain is an optional technology. Previously, the People's Bank of China also held a digital currency seminar. In addition to the central bank, relevant departments such as Zhejiang Province and Beijing Municipality also expressed support for blockchain application research last year.
From an enterprise perspective, Bubi blockchain has been applied in equity, supply chain, points and other fields, and is conducting trials and application tests with exchanges and banks. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. And many blockchain innovative and entrepreneurial companies are constantly emerging.
In addition, a number of industry alliances are being established. In terms of financial institutions, the current cases of blockchain application by my country's large banks and financial institutions still need to be solved.
At the end of 2015, Bank of America had obtained 15 patents on blockchain. There may be a gap of about one and a half years between my country and the United States in blockchain technology.
Blockchain financial applications are entering a new stage in an all-round way. Various applications will become more and more in-depth, and related changes will attract more and more attention, and a huge new trend will form. .
❺ See how the world’s top ten stock exchanges play with blockchain
However, the world’s 10 major stock and commodity exchanges have currently expressed interest in blockchain technology. . In this article, we will give you a detailed introduction:
1. Australian Securities Exchange (ASX)
When it comes to the application of blockchain technology, the ASX is definitely one of them One of the most ambitious companies, it invested more than $10 million in startup Digital Asset Holdings in the industry in January as part of its research and development drive.
At the same time as the investment, the ASX also revealed that it will not only conduct technology trials, but also establish a new post-trade settlement system, which will be developed by Digital Asset through the use of a distributed ledger structure.
However, since January this year, updates on the project’s progress on the ASX may have been overshadowed by controversy. In March, Australian news media began speculating that, although the ASX had reaffirmed its support for the trial, the blockchain project might also be thrown into doubt following the premature resignation of the agency’s CEO Elmer Funke Kupper. Voice,.
2. Chicago Mercantile Exchange Group
CME Group is one of the founders of the "Post-Trade Distributed Ledger Working Group" and has currently carried out very active actions in the industry through its investment arm CME Ventures .
CME Group is unique among its peers. It has always pursued a diversified investment strategy across industries and has successively invested in distributed accounting startup Ripple, blockchain investment group Digital Currency Group and Digital Asset Holdings. Beyond that, however, CME Group has not yet reviewed its expertise in technology and updates.Large industry-wide acts speak out publicly.
3.Deutsche Börse
Deutsche Börse, the operator of Germany’s Frankfurt Stock Exchange, is another player on this list, and it also participated in Digital Asset Holdings’ $60 million financing in January this year.
However, unlike its co-investor ASX, Deutsche Börse has been less vocal about its support for the technology.
In an interview in February, Deutsche Börse said it was working on a proof-of-concept for the technology, although it has yet to release any findings or test results.
4. Dubai Multi Commodity Trading Center
In the Middle East, blockchain-related activities are relatively scarce, and this situation continued until the recent opening of the Global Blockchain Council. The 32-member Global Blockchain Council is a group of startups, financial firms and tech giants that oversees technology applications and their impact.
Built on the basis of these members, Du Multi Commodities Center is a special economic zone and commodity circulation center responsible for overseeing the trading of precious metals and other tangible commodities.
DMCC announced in February that it was engaging in a technology trial with Bitcoin startup BitOasis to explore how blockchain technology could improve its personnel onboarding process.
5. Japan Exchange Group (JPX)
Japan Exchange Group is a relatively active stock market operator in Asia. It announced its interest in the industry in February and has officially formed an alliance with IBM. Become a user of Blockchain-as-a-Service (BaaS).
At the time, reports stated that Japan Exchange Group was embarking on a proof of concept to study the role of blockchain technology in creating a new trading system for low-liquid assets, with the final results to be released through a report later this year announced.
Earlier this month, Japan Exchange Group also announced that it is working with the Nomura Research Institute (NRI) to conduct trials to study how the technology can be applied to the securities market.
6. Korea Exchange
Korea Exchange, South Korea’s only stock exchange and one of the new entrants to this list, announced in February that it would seek to launch a counter via blockchain technology trading platform.
In statements to local news outlets, Korea Exchange said it hopes the technology will help reduce costs. Details about the trial and companies participating in the groupHis condition has not been released.
7. London Stock Exchange (LSE)
The London Stock Exchange is one of the founding institutions of the “Post-Trade Distributed Ledger Working Group” and when it comes to experiments on blockchain technology, the LSE It is one of the most dynamic but also the most low-key institutions.
The London Stock Exchange is one of the first groups to follow in the footsteps of startup R3, and it is the first to say that large financial firms will seek to use collaborative models to conduct blockchain testing, beyond R3’s frame.
It was also from that time that some large financial companies began to participate in private proof-of-concepts and operations in certain areas of the capital market involving various parties.
In addition, like Kouvola Innovation and Japan Exchange Group, the London Stock Exchange is also one of the initial customers of IBM's Blockchain-as-a-Service (BaaS).
8. Nasdaq
When it comes to testing blockchain technology, Nasdaq is probably the most proactive organization. U.S. stock market operator Nasdaq first launched Linq, a private equity trading platform, in 2015, thus becoming the first financial institution to conduct a blockchain proof-of-concept. The platform is currently still in the testing phase.
In addition, Nasdaq has also reached a cooperation with blockchain solution provider Chain and allows its internal experts to speak openly about blockchain technology.
In 2016, Nasdaq continued this momentum. For example, it previously revealed that it is working with Estonia’s Nasdaq OMX Tallinn Stock Exchange on a trial to use blockchain technology to reduce various obstacles to shareholder voting.
9. New York Stock Exchange (NYSE)
The New York Stock Exchange was one of the first companies to take an interest in the industry. In 2015, the NYSE issued two important announcements. The statements are all related to Bitcoin.
In January 2015, NYSE invested in the Bitcoin service company Coinbase as part of its Series C financing. At the time, NYSE Chairman Jeffrey Sprecher said the investment showed confidence in the widespread use of digital currencies by millennials, whom he described as having a more progressive view of value exchange.
The NYSE will continue to launch a Bitcoin price index in May, which will also become a competitor to CoinDesk’s Bitcoin Price Index (BPI), which is plotted with transaction data from the Coinbase trading platform.
10.TMX Group
TMX Group, the operator of the Toronto Stock Exchange, has not been interested in blockchain.Technology clearly expresses its opinion.
However, with the hiring of Anthony Di Iorio (one of the co-founders of Ethereum) as the agency’s first chief digital technology officer, TMX also publicly expressed its interest in the blockchain for the first time in March this year. Interest in chain technology. The next-generation network has become one of the most important blockchain applications in the public eye following its product launch in March.
Nonetheless, TMX Group has stated that it is in the early stages of generating a blockchain strategy and that it may soon be testing the technology. (Babbitt)
11. Puyin Group
Puyin Group launched Puyin, a tea-based digital currency. Puyin is a high-quality Tibetan tea asset that has been warehousing, appraised, evaluated and confirmed by three parties. It is encrypted A digitally issued standard digital currency.
❻ Blockchain can also play a role in food safety. IBM’s “Food Production and Sales History” uses blockchain technology to make Carrefour food safer
Blockchain is not only used for cryptocurrency, IBM is Cooperating with Carrefour requires "tracking" and "traceability" of the source and destination of food through blockchain.
REUTERS/Eric GaillardThis article comes from the cooperative media Dongzu Dongqi. INSIDE authorizes it to be reprinted by Huai Kuan. The original title is "In cooperation with the retail giant Carrefour, the blockchain "Food Production and Sales History" developed by IBM is officially launched. Enter your and my life”
According to a press release issued by the American technology giant IBM on October 8, after “18 months of testing and experimentation”, it will finally officially launch the use of blockchain technology. "Food production and sales history" based on chain technology.
This press release also revealed that the major retail company "Carrefour" will also join this blockchain ecosystem.
Emmanuel Delerm, Carrefour's blockchain director, said that the supermarket chain has been developing its own blockchain system for more than a year, with the main work being operated by its internal engineering team, and then turning to cooperation with IBM.
Carrefour from France has more than 12,000 stores in 33 countries around the world. Now Carrefour plans to use North America as a starting point to take the lead in experiencing blockchain technology for food retail stores. All kinds of benefits come.
According to information released by IBM, Carrefour is planning to roll out this technology to mass-market stores around the world by 2022.
IBM "FoodTrust" - one integration from upstream to downstreamIBM announced the launch of the "Integrity Food" project (IBMFoodTrust) in 2016, trying to use blockchain technology to connect the food industry from upstream to downstream. All businesses.
The plan has entered the trial phase since August 2017 and is being implemented jointly with a number of North American food companies. (Nestle SA, Dole Food Co., Driscoll』s Inc., Gon State Foods, Kroger Co., McCormick and Co., McLane Co., Tyson Foods Inc., Unilever NV.)
Also joining the "Integrity Food" program on Monday were representatives and 15,000 Topco Associates (North America's largest retail food joint purchasing organization, GPO), which works with stores; Wakefern, which works with retailers, representing 50 member companies and 344 stores; and suppliers including Beefchain, DennickFruitSource and Smithfield.
The "Integrity Food" program can also allow other companies to participate through a module that allows companies to upload product-related data to the system through the cloud or other applications, and is free of charge . More advanced versions include features such as certificate certification, organic certification, and fair trade credentials.
According to Coisk, Ramesh Gopinath, vice president of IBM Blockchain Solutions, explained that the main pillar of the IBM Integrity Food Program is the ability to "track" and "trace" items in the supply chain, for example, baby food brands The apples in the system can be pinpointed to specific batches and orchards; then, if contamination occurs, traces can be followed to recover all potentially affected products.
This is obviously a solution that requires food producers, suppliers and retailers to participate and send messages in a "trusted" and "permitted" way, and we connect them together. ,
Gopinath said.
According to IBM, these food companies used the food production and sales blockchain to track millions of products during the trial period of the "Integrity Food" project.
As early as 2016, another major retail company in the United States, "Walmart", had collaborated with IBM to test food production and sales record blockchain, and Walmart had successfully tracked and destroyed it several times. Problem products that have been subject to customer complaints.
In September this year, Walmart also announced that it would require suppliers selling leafy vegetables to join this food production and sales blockchain ecosystem in the future.
For IBM, the food industry is just an outpost for their use of blockchain technology. After all, IBM ranks first in the world in the number of patents it has applied for in blockchain technology, competing with Chinese e-commerce company Alibaba. Same name.
❼ Coin Bank Bitcoin Stability IBM proposes principles for commercial application of blockchain
According to the transaction data of OKCoin, a well-known domestic Bitcoin exchange platform, yesterday (April) 10th) After the market opened, the currency price briefly rushed to a new high of 7330 and then began to show an obvious decline. The price fluctuated all the way down, but the overall decline was limited, with the lowest only falling.It reached the 7180 line in early trading today. As of press time, the currency price was last trading around 7250.
?
Transaction data of OKCoin, a well-known domestic Bitcoin exchange platform
OKCoin analysts said that at the daily level, yesterday’s daily The line closes the small spindle line with a slightly longer shadow line. The upper part continues to be suppressed by MA60, causing the high pressure to fall back. MA5 is still in an upward state and forms an effective support for the price. The space between pressure and resistance further shrinks; 4 hours At the 1-hour level, the moving average system (5, 10, 20) once again tends to stick to the winding operation, and the low point moves upward unchanged, but the high point cannot effectively reach a new high; at the 1-hour level, the price shows a narrow and weak oscillation trend, and the trading volume The contraction is obvious, and the MACD Express Line (DIF) has a tendency to cross the zero axis.
In terms of industry, OKCoin learned that blockchain or distributed ledger technology is rapidly entering enterprises. Just like the Internet revolutionized communications in the 1990s, blockchain may become transformative for commercial transactions. technology. In the supply chain and logistics industry alone, this technology could save billions of dollars every year, drastically reducing delays and failures. The potential impact is far-reaching, with the World Economic Forum stating that reducing barriers to the development of international supply chains could increase global GDP by almost 5% and total transaction volume by 15%.
In order to best obtain the value of blockchain technology, IBM recommends technology users in supply chains and important industries such as finance, retail, and energy to deeply understand the core elements of this technology.
1. Blockchain contains the potential to transform trade, transactions and business processes
There are two concepts at the bottom of blockchain, "business network" and "ledger". Put together, blockchain is a smart, immutable way to conduct trade, transactions and business processes. Network members conduct asset transactions through a ledger that is visible to all members. The ledgers are synchronized in the network, and all members need to confirm the transaction information of tangible and intangible assets before asset transactions are recognized and recorded on the blockchain. This consensus helps achieve legitimacy and transparency, even if the transaction parties are not familiar with each other.
2. As the blockchain network develops, its value will be reflected in the ecosystem
As a business network, blockchain can include different types of participants. The number of participants in a blockchain network, the value of the assets to be traded, and the need to provide various qualifications and authorizations to participants all make it important for technology adopters to pay attention to the differences between "permissioned" and "permissionless" blockchain networks. . The realization of the real value of blockchain relies on the development of business networks. The powerful ecosystem enables business networks to easily reach the critical majority, allowing users to build new business models and transform transaction processes.
3. Blockchain can greatly improve business visibility and trust
Blockchain can reduce transaction settlement time from days to seconds, and all participants can browse . The technology can also cut excessive costs and eliminate third parties, especially transactionsVerification of required intermediaries. Because blockchain is built on the concept of trust, it can reduce the risk of illegal activities in the payment network and eliminate fraud and cybercrime.
Speed, cost-effectiveness and transparency are among the greatest benefits that blockchain can bring to enterprises and enterprise ecosystems. For example, IBM, Walmart and Tsinghua University are using blockchain technology to solve food safety threats. Blockchain allows supply chain participants to see the same records and can narrow down the source of contamination.
❽ The blockchain revolution is coming, what impact will it have on IBM and Uber?
Zhao Liang, general manager of the banking industry of IBM Global Business Consulting Services, believes that in supply chain finance, digital bills, Blockchain technology has broad application prospects in Internet financial fields such as P2P financial management, electronic money, microfinance, cross-border payments, collateral management and contract execution, and can better connect financial institutions and non-financial enterprises.
The principles of blockchain can also be more widely used in other innovative fields. For example, blockchain is expected to establish a points exchange and transaction system for the exchange and transaction of various points such as telecom phone bill points, airline mileage points, and hotel accommodation points. In the field of Internet of Things, IBM has cooperated with Finland's Kouvola Innovation to establish a trusted cargo view of the entire logistics process based on blockchain and Watson Internet of Things technology.
In fact, the Internet of Things will become one of the most exciting and largest application areas of blockchain in the next few years. Blockchain solves the trust problem and financial transactions between massive devices and nodes in the Internet of Things. The Internet of Things based on blockchain and electronic money can allow smart home appliances to automatically complete financial transactions such as paying electricity bills, and IBM Watson cognitive technology can automatically recommend more reasonable power usage levels by learning historical data. From the perspective of the whole society, A true smart grid can be formed.
In May 2016, two Chinese blockchain companies announced that they would join the HyperLedger project led by IBM and the Linux Foundation. Also in May, Ping An Insurance Group announced that it would join the international R3 Alliance and work with other financial institutions to jointly develop innovative business applications based on distributed shared ledger technology.
Now, blockchain is not only about influencing Internet technology, but also about creating a new decentralized next-generation business model. This is the true meaning of the blockchain revolution.
