1. 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, Blockchain technology has broad application prospects in Internet financial fields such as digital bills, 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.
2. IBM and Walmart apply 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. The project, linked to the U.S. Drug Supply Chain Security Act, is designed 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 disks. 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!
3. 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. superiorIn March, Brazilian bank and financial infrastructure service provider CIP officially launched a blockchain ID platform using Hyperledger Fabric in cooperation 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.
4. Which company’s product is the blockchain technology patent?
Blockchain technology is a public technology, and many companies and organizations are involved in the research and development of blockchain. applied and obtained a patent. Currently, no company owns a patent on blockchain technology, but some companies already have a large number of patents in this field. For example, IBM has applied for a large number of technology patents in the field of blockchain and is considered to be one of the companies with the largest number of patent applications in blockchain technology in the region. In addition, companies or organizations such as Microsoft, Huawei, Oracle, and Alibaba also own many patents related to blockchain technology. Therefore, blockchain technology does not belong to a specific company or organization, but is a technology jointly developed and applied by many companies and organizations.
5. VISA and IBM launch the "Visa B2B Connect" blockchain digital identity solution to make credit card transactions safer
The digital identity solution jointly developed by VISA and IBM will store sensitive business data , such as bank details and account numbers, are tokenized and given a special cryptographic identifier for use in transactions on the platform.

According to foreign media, Visa, a multinational financial services company headquartered in California, will cooperate with IBM in 2019. In the first quarter of this year, a cross-border payment digital identity verification system using blockchain technology was launched.
The system, called VisaB2BConnect, will provide financial institutions with digital identity solutions based on blockchain technology and provide secure cross-border payment processing. According to reports, the system tokenizes sensitive business data, such as bank details and account numbers, and assigns them special cryptographic identifiers for use in transactions on the platform.
Kevin Phalen, Visa’s head of global business solutions, said the system will help improve fraud. "B2BConnect's digital identity recognition system greatly reduces the risk of fraud that may occur in checks, collections and wire transfers today, while also helping companies comply with financial regulations and become part of a regulated financial ecosystem."
< p>From a technical point of view, the solution will integrate the Hyperledger Fabric architecture (led by Linux and developed with input from IBM) and Visa's "core assets". The company said it would build aA scalable network and used in the finance department.
Jason Kelley, general manager of IBM Blockchain Services, said the system is "one of the most powerful examples of blockchain technology changing payments to date." He said: "When the payment and financial services technology fields When leaders in the industry work together to develop open source technologies, the entire industry benefits, and the IBM Blockchain Platform and Hyperledger technologies are delivering real business value."
Based on the 40-year relationship between Visa and IBM, this Seems like a natural progression, underscoring both companies’ commitment to ensuring a flawless cross-border payments experience and maximum security, trust and transparency in financial transactions.
6. 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 (4 On March 10), the currency price briefly reached a new high of 7330 after opening, and then began to show an obvious decline. The price fluctuated all the way down, but the overall decline was limited, and the lowest only dropped to 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 the smart, tamper-proof way to conduct trade, transactions and business processes.Change the way. 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 reduce exorbitant costs and eliminate the need for third parties, especially middlemen, to verify transactions. 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.
7. 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 a book Ledgers, reading and writing databases can be regarded as a kind of bookkeeping behavior. The principle of blockchain technology is to find the person with the fastest and best bookkeeping within a period of time. This person will do the bookkeeping, and then the ledger will be recorded. One page of information is sent to everyone else in the entire system.
8. How to learn blockchain technology_How to understand blockchain technology
1. Technical language
Python and Go are two languages that are used by many companies Technical language is mentioned in recruitment. Need to prioritize learning. Moreover, these two languages also have great applications in the direction of sliding technology outside of the blockchain. For example, Go is used in the background construction of large-scale concurrent systems, and Python is used in the construction of artificial intelligence systems. So learning these two languages is a priority.
2. Technical framework
Master one or more of Bitcoin, ETH and Hyperledger. Needless to say about BTC, the bottom layer is written in C. A large number of currency projects, such as Litecoin, Dash, Monero, zcash, etc., all use Bitcoin technology for secondary development.
ETH isAs a representative of Blockchain 2.0, various application Dapps can be built on the ETH network. Nowadays, a large number of application blockchain projects are developed using the ETH platform.
Hyperledgerfabric is a blockchain development platform strongly promoted by IBM. It is mainly used for the development of alliance chains. It is currently the most popular alliance chain development platform.
3. Algorithm
POW (Proof of Work Algorithm), POS (Proof of Stake Algorithm), PBFT (Byzantine Fault Tolerance Algorithm), etc. are all important in the cryptography part of the blockchain Composition, a full understanding of these algorithms will help you have a better understanding of the cryptography part when participating in the underlying development of blockchain projects.

Blockchain technology is a distributed accounting technology, and its characteristics are decentralization, Openness and transparency allow everyone to participate in the establishment of the database, and each created data cannot be tampered with. With everyone participating, the problem of trust between strangers is solved.
Blockchain technology has emerged. It is an accounting technology that involves the participation of all people. The transaction information and data between AB are published to the public and cannot be tampered with. Everyone knows this. happens, then there is no need for any authoritative third-party C, or everyone in the system plays the role of C. This is also called decentralization.
9. 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 The cooperation with Carrefour requires the use of blockchain to "track" and "trace" the source and whereabouts of food.
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.)
Join " on Monday Also participating in the "Integrity Food" initiative are Topco Associates, North America's largest retail grocery purchasing organization (GPO), which works with 15,000 stores; Wakefern, which works with retailers, representing 50 member companies and 344 stores; and Beefchain , DennickFruitSource and Smithfield, among other suppliers.
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, Wal-Mart also announced that it would require the sale of leafy vegetables in the future.Suppliers join this food production and marketing blockchain ecosystem.
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.
