There has been a lot of noise on cryptocurrencies and Bitcoin of late. While some suggest cryptocurrencies are a fraud , others believe them to be the next biggest economic revolution the world has seen since the internet. Bitcoin has brought to light blockchain technology, which offers great potential for food safety and verification in the agrifood sector. Yet it is far from being the panacea for a range of issues affecting the industry at least for now. Simply put, blockchain technology is a way of storing and sharing information across a network of users in an open virtual space. Blockchain technology allows for users to look at all transactions simultaneously and in real-time. In food, for example, a retailer would know with whom his supplier has had dealings. Additionally, since transactions are not stored in any single location, it is almost impossible to hack the information. For consumers, blockchain technology can make a difference. By reading a simple QR code with a smartphone, data such as an animals date of birth, use of antibiotics, vaccinations, and location where the livestock was harvested can easily be conveyed to the consumer. Yaxi Hu, a researcher at the University of British Columbia, developed a test to identify fore Continue reading >>

The Blockchain technology PowerPoint templates include four slides. Check detailed conception of Blockchain in Wikipedia . Slide 1, Blockchain technology PowerPoint templates for three networks comparison. Firstly blockchain, originally block chain, is a continuously growing list of records, calling blocks. It is using cryptography to link and secure. Secondly by design, block chain is inherently resistant to modification of the data. Thirdly this makes blockchains potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing, documenting provenance, food traceability or voting. You can found them in our PowerPoint templates. Slide 2, Block chaintechnologyillustration For use as a distributed ledger, a block chain is typically managed by a peer-to-peer network. The network is collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks. The alteration requires collusion of the network majority. Slide 3, Five key forces of Block chain technology It is five forces that are key to Block chain technology; they are Establishing transparent P2P Continue reading >>

Blockchain: The Invisible Technology That's Changing The World

Blockchain: The Invisible Technology That's Changing The World

Blockchain: The Invisible Technology That's Changing the World Blockchain-based networks, decentralized apps (DApps), and distributed ledgers are becoming the foundation of much of your digital life. There's a new immutable digital fabric remaking the internet beneath us, and you probably don't even realize it. PCMag reviews products independently , but we may earn affiliate commissions from buying links on this page. Terms of use . Blockchain isn't a household buzzword, like the cloud or the Internet of Things. It's not an in-your-face innovation you can see and touch as easily as a smartphone or a package from Amazon. But in a world where anyone can edit a Wikipedia entry, blockchain is the answer to a question we've been asking since the dawn of the internet age: How can we collectively trust what happens online? Every year we run more of our livesmore core functions of our governments, economies, and societieson the internet. We do our banking online. We shop online . We log into apps and services that make up our digital selves and send information back and forth. Think of blockchain as a historical fabric underneath recording everything that happensevery digital transaction; exchange of value, goods and services; or private dataexactly as it occurs. Then the chain stitches that data into encrypted blocks that can never be modified and scatters the pieces across a worldwide network of distributed computers or "nodes." Think about a blockchain as a distributed database that maintains a shared list of records. These records are called blocks, and each encrypted block of code contains the history of every block that came before it with timestamped transaction data down to the second. In effect, you know, chaining those blocks together. Hence blockchain. A blockchain Continue reading >>

What Is Blockchain Technology? I Want To Make Ppt On It So Give Me Deep Or Some Information About That.

Blockchain is a revolutionary technology that puts the trust from third parties into our own hands Blockchain at its core is a decentralised ledger to validate and transact our data globally. Blockchain allows for instant and secure global exchanges, it provides protection of our information and publicly displayed records of all transactional data. Blockchain also allows for smart contracts and decentralised apps to be incorporated into the ecosystem. Blockchain will revolutionise a huge number of industries, here a few great examples of why blockchain will be so powerful: Voting with a distributed ledger, we can validate each and every vote and ensure no manipulation by third parties is occurring. Allows the unbanked to send money across borders over 2 billion people do not have access to bank accounts, blockchain will enable them to send money home and economically better their families. Secure data storage encrypted data will be fractionally stored across the blockchain, giving only the owner of the data access to the data when required. Contracts smart contracts can be written into the blockchain to automatically trigger responses based on real time events. Continue reading >>

Blockchain, Explained

Blockchain, Explained

An MIT expert on why distributed ledgers and cryptocurrencies have the potential to affect every industry. Like the internet in its early years, blockchain technology is hard to understand and predict, but could become ubiquitous in the exchange of digital and physical goods, information, and online platforms. Figure it out now. Blockchain is a term widely used to represent an entire new suite of technologies. There is substantial confusion around its definition because the technology is early-stage, and can be implemented in many ways depending on the objective. At a high level, blockchain technology allows a network of computers to agree at regular intervals on the true state of a distributed ledger, says MIT Sloan Assistant Professor Christian Catalini, an expert in blockchain technologies and cryptocurrency. Such ledgers can contain different types of shared data, such as transaction records, attributes of transactions, credentials, or other pieces of information. The ledger is often secured through a clever mix of cryptography and game theory, and does not require trusted nodes like traditional networks. This is what allows bitcoin to transfer value across the globe without resorting to traditional intermediaries such as banks. On a blockchain, transactions are recorded chronologically, forming an immutable chain, and can be more or less private or anonymous depending on how the technology is implemented. The ledger is distributed across many participants in the network it doesnt exist in one place. Instead, copies exist and are simultaneously updated with every fully participating node in the ecosystem. A block could represent transactions and data of many types currency, digital rights, intellectual property, identity, or property titles, to name a few. The tech Continue reading >>

Lawyers Get Ready, Theres A Blockchain Coming

Lawyers Get Ready, Theres a Blockchain Coming Lawyers Get Ready, Theres a Blockchain Coming Lawyers have an ethical requirement of competence. Comment 8 to Rule 1.1 of the Model Rules of Professional Conducts (1) specifically refers to technological competence as part of the general duty. Comment 8 says, in its pertinent part, that [t]o maintain the requisite knowledge and skill, a lawyer should keep abreast of changes in the law and its practice, including the benefits and risks associated with relevant technology, engage in continuing study and education and comply with all continuing legal education requirements to which the lawyer is subject. A major practical difficulty of the duty of technology competence is predicting the likely impact and relevance of a new technology. Its one thing to say that a lawyer needs to learn how to understand and use existing technologies like standard Microsoft Office software. Its quite another to determine when a new technology becomes a relevant technology that requires a lawyer to keep abreast. What is relevant technology? What does it mean to keep abreast? What reasonable and practical approaches should you be expected to take? That makes one of todays hottest new technologies, the blockchain, a very interesting case study. According to Gartner, blockchain is at the top of the Hype Cycle for an emerging technology. You may know it through references to bitcoin, a cryptocurrency popularized through ransomware and the trial of Ross Ulbricht and the Silk Road. Bitcoin is just one use of blockchain technology. As a technological platform, many smart people believe that it will dramatically change the way business and finance are handled, identity is managed, and transactions are validated and tracked. And some believe that one aspec Continue reading >>

How Blockchain Could Give Us A Smarter Energy Grid

How Blockchain Could Give Us A Smarter Energy Grid

How Blockchain Could Give Us a Smarter Energy Grid Energy experts believe that blockchain technology can solve a maze of red tape and data management problems. On an electricity grid, electrons generated from the sun, wind, or other renewable sources are indistinguishable from those generated by fossil fuels. To keep track of how much clean energy is produced, governments around the world have created systems based on tradable certificates. Problem is, the way we manage these certificates sucks, and its holding up investment in renewable power, says Jesse Morris, an energy expert at the Rocky Mountain Institute . A new system based on blockchain, the technology at the heart of Bitcoin and other digital currencies, could fix this, he says. Keeping track of renewable-energy certificates is one of dozens of potential applications of blockchain technology that could solve data management challenges in the electricity sector without disrupting business as usual, according to Morris. He and many others believe that in the long term, the technology could help transform the very architecture of the grid itself. A blockchain is a shared, encrypted ledger that is maintained by a network of computers. These computers verify transactionsin the case of Bitcoin, the transfer of cryptocurrency between individual users. Each user can access the ledger, and there is no single authority (see Why Bitcoin Could Be Much More Than a Currency ). Advocates say the technology could be especially promising in industries where networks of peerselectricity producers and consumers, connected via the grid, for instancedepend on shared sets of data.

Blockchain Technology & The Future Of Transactions

Blockchain Technology & The Future Of Transactions

Blockchain Technology & The Future of Transactions The Blockchain and the Future of Transactions Blockchain technology is transformative, and several commentators expect that it will have a massive economic impact similar to the one the Internet has had in the past few decades. Since blockchain technology is at the heart of Bitcoin and other virtual currencies, it can at the very least be expected to power even more consequential mediums of exchange in the future. However, virtual currencies are merely the first use case of blockchain technology. The blockchain is an open and distributed ledger. It uses an append-only data structure, meaning new transactions and data can be added on to a blockchain, but past data cannot be erased. This results in a verifiable and permanent record of data and transactions between two or more parties. This has the potential to increase transparency and accountability, and positively enhance our social and economic systems. A blockchain is built by running software and linking several nodes together. A blockchain is not one global entity there are several blockchains. Imagine a network of connected computers inside a highly secure office, which are connected to each other, but not to the internet. A blockchain is similar to this: it can have numerous connected nodes, but remain totally separate and unique from other blockchains. Institutions and banks can build internal blockchains with their own features for various organizational purposes. A consensus mechanism and a reward system are required to maintain the integrity and functionality of a blockchain. In the Bitcoin blockchain, consensus is achieved by mining, and the reward system is a protocol awarding a miner some amount of Bitcoin upon successfully mining a block. Mining is undert Continue reading >>

What Is Blockchain Technology? A Step-by-step Guide For Beginners

What Is Blockchain Technology? A Step-by-step Guide For Beginners

What is Blockchain Technology? A Step-by-Step Guide For Beginners Angel Investors, Startups & Blockchain developers... Is blockchain technology the new internet? The blockchain is an undeniably ingenious invention the brainchild of a person or group of people known by the pseudonym, Satoshi Nakamoto . But since then, it has evolved into something greater, and themain question every single person is asking is: What is Blockchain? By allowing digital information to be distributed but not copied, blockchain technology created the backbone of a new type of internet. Originally devised for the digital currency , Bitcoin , the tech community is now finding other potential uses for the technology. Bitcoin has been called digital gold, and for a good reason. To date, the total value of the currency is close to $9 billion US. And blockchains can make other types of digital value. Like the internet (or your car), you dont need to know how the blockchain works to use it. However, having a basic knowledge of this new technology shows why its considered revolutionary. So, we hope you enjoy this, what is Blockchain guide. The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value. Picture a spreadsheet that is duplicated thousands of times across a network of computers. Then imagine that this network is designed to regularly update this spreadsheet and you have a basic understanding of the blockchain. Information held on a blockchain exists as a shared and continually reconciled database. This is a way of using the network that has obvious benefits. The blockchain database isnt stored in any single location, meaning the records it keeps are truly public and easily verif Continue reading >>

With blockchain technology, youcould create a truly tamper-proofrecord system records can go intothe Blockchain in a way that I knowif anybody tries to change it. You should be taking this technology as seriously as you should have been taking the development of the Internet in the early 1990s. Both the financial services and Bitcoin communities perked up last week when Citi, Nasdaq, Visa and other large financial institutions invested in Chain.com, a Bitcoin blockchain services provider. Bitcoin is giving banks a run fortheir money. Now the sametechnology threatens to eradicatesocial networks, stock markets, evennational governments. A blockchain is an audit trail for a database which is managed by a network of computers where no single computer is responsible for storing or maintaining the database, and any computer may enter or leave this network at any time without jeopardizing the integrity or availability of the database. Any computer can rebuild the database from scratch by downloading the blockchain and processing the audit trail. Traditional databases are maintained by a single organization, and that organization has complete control of the database, including the ability to tamper with the stored data, to censor otherwise valid changes to the data, or to add data fraudulently. For most use cases, this is not a problem since the organization which maintains the database does so for its own benefit, and therefore has no motive to falsify the databases contents; however, there are other use ca Continue reading >>

Consensus 2017: Ibm Thinks Blockchain Could Save Shipping Industry 'billions'

Consensus 2017: Ibm Thinks Blockchain Could Save Shipping Industry 'billions'

Consensus 2017: IBM Thinks Blockchain Could Save Shipping Industry 'Billions' May 22, 2017 at 16:28 UTC|UpdatedMay 22, 2017 at 18:35 UTC Blockchain technology is poised to recover billions of dollars lost to coordination costs in both capital markets and the shipping industry, according to Arvind Krishna, the director of research at IBM. Krishna argued this point during a presentation at CoinDesk's Consensus 2017 conference in New York. Among other projects, Krishna described a partnership with Maersk , a Danish transport company, whichhe says will cut costs by streamlining the checks that shipping companies are required to go through as they transport goods across international borders. A typical shipment, according to Krishna, must pass the scrutiny of about 30 organizations during its circuitous journey to the market. Every hold up in this process nicks dollars off the profitability of the product. "A single piece of paper, if it's missing when it arrives in Rotterdam, means that a container full of avocados just sits there. A few days extra of sitting there and you've got to throw out the whole container because you've crossed the limit of how long those goods can sit there without being considered spoiled," said Krishna. Blockchains, he went on to say, are an ideal platform for aggregating and transmitting the certifications required at each step along the way and could shave twenty percent of the cost from international shipping. "We believe that just doing this kind of digitization can result in tens of billions of dollars saved across that network,"he said. Arvind also touted blockchains as a solution for verifying that diamonds originate from conflict-free zones and mentioned that Walmart is looking into the technology as a way to track and verify organic prod Continue reading >>

Blockchain 101 Blockchain Education Network Medium

Blockchain 101 Blockchain Education Network Medium

Every informed person needs to know about the Blockchain because it might be one of the worlds most important developments LeonLuow Bitcoin and Blockchain technology have quickly poured into the mainstream, but its technical roots have caused many early adopters to use complicated jargon when trying to explain it. Lets try to demystify it. Some Background Why Do We Even NeedIt? It provides a trustworthy infrastructure for the transfer of assets. As you all know, for the past two decades, the internet has impacted how our society shares and diffuses information. The internets infrastructure allows us to seamlessly share copies of our favorite files at the touch of a button. Great. But when it comes to assets and value, sending a copy while the sender has the ability to keep an original becomes an issue. Double spending is exactly what it sounds like, spending multiple times on one transaction (yes, its illegal). The current system does not provide a trustworthy infrastructure when it comes to assets and the transfer of value, as there has never been a way to directly exchange value in the digital space without the use of intermediaries. We rely on middlemen or intermediaries like banks, commerce platforms or governments to establish the element that allows our economy to function in a digitized space: trust. These third parties perform transactional logistics like authentication, record keeping or payment clearance to ensure that both parties in a transaction oblige to some pre-specified terms and conditions, and thus allowing the buyer and seller to remain confident that the transaction will execute in a secure and effective manner. While these intermediaries are crucial to our digital economy, there are some major issues: 1. They use centralized databases which face h Continue reading >>
