Making sense of blockchain technology
Blockchain promises to solve this problem. The technology behind bitcoin, blockchain is an open, distributed ledger that records transactions safely, permanently, and very efficiently. For instance, while the transfer of a share of stock can now take up to a week, with blockchain it could happen in seconds.
Blockchain could slash the cost of transactions and eliminate intermediaries like lawyers and bankers, and that could transform the economy.
In this article the authors describe the path that blockchain is likely to follow and explain how firms should think about investments in it. The level of complexity—technological, regulatory, and social—will be unprecedented. Contracts, transactions, and the records of them are among the defining structures in our economic, legal, and political systems. They protect assets and set organizational boundaries. They establish and verify identities and chronicle events.
They govern interactions among nations, organizations, communities, and individuals. They guide managerial and social action. In a digital world, the way we regulate and maintain administrative control has to change. The technology at the heart of bitcoin and other virtual currencies, blockchain is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. The ledger itself can also be programmed to trigger transactions automatically.
Each party on a blockchain has access to the entire database and its complete history. No single party controls the data or the information. Every party can verify the records of its transaction partners directly, without an intermediary. Communication occurs directly between peers instead of through a central node. Each node stores and forwards information to all other nodes. Every transaction and its associated value are visible to anyone with access to the system. Each node, or user, on a blockchain has a unique plus-character alphanumeric address that identifies it.
Users can choose to remain anonymous or provide proof of their identity to others. Transactions occur between blockchain addresses. Various computational algorithms and approaches are deployed to ensure that the recording on the database is permanent, chronologically ordered, and available to all others on the network.
The digital nature of the ledger means that blockchain transactions can be tied to computational logic and in essence programmed.
So users can set up algorithms and rules that automatically trigger transactions between nodes. With blockchain, we can imagine a world in which contracts are embedded in digital code and stored in transparent, shared databases, where they are protected from deletion, tampering, and revision.
In this world every agreement, every process, every task, and every payment would have a digital record and signature that could be identified, validated, stored, and shared. Intermediaries like lawyers, brokers, and bankers might no longer be necessary.
Individuals, organizations, machines, and algorithms would freely transact and interact with one another with little friction. This is the immense potential of blockchain. Indeed, virtually everyone has heard the claim that blockchain will revolutionize business and redefine companies and economies.
Although we share the enthusiasm for its potential, we worry about the hype. It would be a mistake to rush headlong into blockchain innovation without understanding how it is likely to take hold. True blockchain-led transformation of business and government, we believe, is still many years away. Blockchain is a foundational technology: It has the potential to create new foundations for our economic and social systems.
But while the impact will be enormous, it will take decades for blockchain to seep into our economic and social infrastructure. The process of adoption will be gradual and steady, not sudden, as waves of technological and institutional change gain momentum. Department of Defense precursor to the commercial internet. To ensure that any two nodes could communicate, telecom service providers and equipment manufacturers had invested billions in building dedicated lines.
The new protocol transmitted information by digitizing it and breaking it up into very small packets, each including address information. Once released into the network, the packets could take any route to the recipient.
There was no need for dedicated private lines or massive infrastructure. Few imagined that robust data, messaging, voice, and video connections could be established on the new architecture or that the associated system could be secure and scale up. To do so, they developed building blocks and tools that broadened its use beyond e-mail, gradually replacing more-traditional local network technologies and standards. As organizations adopted these building blocks and tools, they saw dramatic gains in productivity.
Netscape commercialized browsers, web servers, and other tools and components that aided the development and adoption of internet services and applications. Sun drove the development of Java, the application-programming language.
As information on the web grew exponentially, Infoseek, Excite, AltaVista, and Yahoo were born to guide users around it. Once this basic infrastructure gained critical mass, a new generation of companies took advantage of low-cost connectivity by creating internet services that were compelling substitutes for existing businesses. CNET moved news online.
Amazon offered more books for sale than any bookshop. Priceline and Expedia made it easier to buy airline tickets and brought unprecedented transparency to the process. The ability of these newcomers to get extensive reach at relatively low cost put significant pressure on traditional businesses like newspapers and brick-and-mortar retailers. Relying on broad internet connectivity, the next wave of companies created novel, transformative applications that fundamentally changed the way businesses created and captured value.
These companies were built on a new peer-to-peer architecture and generated value by coordinating distributed networks of users. Think of how eBay changed online retail through auctions, Napster changed the music industry, Skype changed telecommunications, and Google, which exploited user-generated links to provide more relevant results, changed web search.
Companies are already using blockchain to track items through complex supply chains. The very foundations of our economy have changed.
Blockchain—a peer-to-peer network that sits on top of the internet—was introduced in October as part of a proposal for bitcoin, a virtual currency system that eschewed a central authority for issuing currency, transferring ownership, and confirming transactions. Bitcoin is the first application of blockchain technology. Just as e-mail enabled bilateral messaging, bitcoin enables bilateral financial transactions. A team of volunteers around the world maintains the core software.
And just like e-mail, bitcoin first caught on with an enthusiastic but relatively small community. Similarly, blockchain could dramatically reduce the cost of transactions. It has the potential to become the system of record for all transactions. If that happens, the economy will once again undergo a radical shift, as new, blockchain-based sources of influence and control emerge.
Consider how business works now. Keeping ongoing records of transactions is a core function of any business. Those records track past actions and performance and guide planning for the future. Many organizations have no master ledger of all their activities; instead records are distributed across internal units and functions.
The problem is, reconciling transactions across individual and private ledgers takes a lot of time and is prone to error. For example, a typical stock transaction can be executed within microseconds, often without human intervention. However, the settlement—the ownership transfer of the stock—can take as long as a week.
Instead a series of intermediaries act as guarantors of assets as the record of the transaction traverses organizations and the ledgers are individually updated.
In a blockchain system, the ledger is replicated in a large number of identical databases, each hosted and maintained by an interested party. When changes are entered in one copy, all the other copies are simultaneously updated. So as transactions occur, records of the value and assets exchanged are permanently entered in all ledgers. There is no need for third-party intermediaries to verify or transfer ownership.
If a stock transaction took place on a blockchain-based system, it would be settled within seconds, securely and verifiably. The infamous hacks that have hit bitcoin exchanges exposed weaknesses not in the blockchain itself but in separate systems linked to parties using the blockchain. If bitcoin is like early e-mail, is blockchain decades from reaching its full potential? In our view the answer is a qualified yes. The adoption of foundational technologies typically happens in four phases.
Each phase is defined by the novelty of the applications and the complexity of the coordination efforts needed to make them workable. Applications low in novelty and complexity gain acceptance first. Applications high in novelty and complexity take decades to evolve but can transform the economy.
In our analysis, history suggests that two dimensions affect how a foundational technology and its business use cases evolve. The first is novelty—the degree to which an application is new to the world. The more novel it is, the more effort will be required to ensure that users understand what problems it solves. The second dimension is complexity, represented by the level of ecosystem coordination involved—the number and diversity of parties that need to work together to produce value with the technology.
For example, a social network with just one member is of little use; a social network is worthwhile only when many of your own connections have signed on to it. Other users of the application must be brought on board to generate value for all participants.
The same will be true for many blockchain applications. And, as the scale and impact of those applications increase, their adoption will require significant institutional change.
Identifying which one a blockchain innovation falls into will help executives understand the types of challenges it presents, the level of collaboration and consensus it needs, and the legislative and regulatory efforts it will require. Managers can use it to assess the state of blockchain development in any industry, as well as to evaluate strategic investments in their own blockchain capabilities.
In the first quadrant are low-novelty and low-coordination applications that create better, less costly, highly focused solutions. Bitcoin, too, falls into this quadrant.
Facilitating online trust with blockchains
Think of a database with information stored in blocks. These blocks can be copied and replicated on individual computers. All of these are identical and synced with one another. When someone adds or subtracts data, it changes the information across them all. Each one is just as secure as your online banking portal — nearly unhackable. Blockchain ledgers can incorporate a wide swath of documents, including loans, land titles, logistics manifests, and almost anything of value. Big Data information can be shared in a multi-verification environment that is perfect for real-time, secure information sharing.

This review article discusses the adoption of blockchain in the ports and shipping industry to support digital transformation. It also explores the integration of this technology into the current ports and shipping ecosystem. Besides, the study highlighted the situation of the supply chains management in ports and shipping domain as a case study in this field.
The Truth About Blockchain
I studied computer science and engineering, so I always follow the latest IT innovations. In other words, I came to blockchain through an interest in the technology rather than because of the hype surrounding Bitcoin. This technology has a unique, disruptive and transformative value proposition. Blockchain makes it possible to make business processes more efficient, optimise existing business models and even create entirely new ones. Blockchain technology will simplify and accelerate processes, transform business models and create new types of business.
Everything You Need to Know About Blockchain Technology
Blockchain is a technology that allows to store and transmit digital data, financial or not, in a reliable and secure way. It is a distributed database, i. Each transaction, whatever it is, is written indelibly in a large transparent register that everyone can consult without ever being able to modify the previous entries. This register is made up of blocks which are themselves made up of hundreds of transactions. These blocks are added to each other forming chains, hence the term blockchain. For a transaction to be recorded in a blockchain in a permanent way, users, then called "miners", analyze each "block" to verify its validity.
Why Use Blockchain Technology?
T here are not many occasions when one can give an unqualified thumbs-up to something the government does, but this is one such occasion. Since this is the kind of talk one normally hears from loopy startup founders pitching to venture capitalists rather than from sober Whitehall mandarins, it made this columnist choke on his muesli — especially given that, in so far as Joe Public thinks about distributed ledgers at all, it is in the context of Bitcoin, money laundering and online drug dealing. So what, one is tempted to ask, has the chief scientific adviser been smoking?
Blockchain technologies has shown not to be limited to the financial sector, large organizations from various industries are also exploring how adopting blockchain could help their business. Blockchain technology was originally created in relation to cryptocurrency; however, it is essentially a distributed database that can store any type of records. It is highly secure and only grants access for modification within what you own, but anyone can see it, which is also highly transparent. The necessity to hire people with Blockchain skills has increased, and the race to become the first to establish market share is the biggest motivation for all involved in the process. Whether you are representing a company directly or indirectly, as a developer or from a managerial position, roles that are linked to the the development of such technologies will provide the foundations of what can become a standard in Blockchain. Blockchain developers are in high demand, their skills are not common, and the role is starting to be known as Blockchain Engineers.
