2. The Impact on Internet of Things (IoT)
Though DLT adoption rates across industries vary, the overall popularity of the technology is steadily expanding. In , experts predict an increased demand for Federated Blockchain aka Consortium Blockchain which is an updated version of the traditional private blockchain.
Under the private blockchain model, the network is ruled by a single organization and new entrants need permission to view, edit, or otherwise manage the data. There are different levels of access, depending on your status in the system. The federated blockchain applies the same invitation-only principle, but it is managed by multiple consortium members.
This makes FB a perfect choice for organizations and business groups in which power is distributed across several decision-makers.
This combined model features higher scalability and is a better fit for collaboration. Some skeptics argue that private blockchains, FB included, go against the very idea of decentralization.
However, such systems remain perfect solutions for associations seeking to effectively manage their commercial information between themselves. Today, more and more organizations want to solve the problems traditional databases cause, and the distributed ledger technology has an equally useful role to play here. Therefore, federated blockchain is one of the hottest tech trends. It has great potential in banking, healthcare, supply chain, and other sectors where both trust and privacy are vitally important.
Blockchain-as-a-Service not to be confused with Banking-as-a-Service, which uses the same BaaS abbreviation is another trend to keep a watchful eye on. The term applies to a cloud service that makes it easier for clients to develop and run their blockchain apps. The benefits are clear.
Any business or individual can outsource complicated tech tasks to a BaaS provider. Thanks to this impressive blockchain trend, you can focus on your business tasks. A lot of startups are now relying on this model.
They connect with the established blockchain networks and use their resources. Stablecoin is a hybrid of crypto and fiat currencies. Some stablecoins can be backed by a commodity like gold or oil.
The idea behind the stablecoin was to combine the advantages of both digital and normal assets. Like typical crypto, stablecoin is fast and easy to transfer. In total, there are about stablecoins, including those running on the major blockchain platforms. The leader is Ethereum. According to Statista , over 3.
We often have little or no control over our personal information and the content we publish. The same applies to the content we see in our news feed. If there are any security breaches, our accounts may be compromised. This is when decentralized solutions come to the rescue. Blockchain has the potential to address pressing social media problems such as:. An interesting example of a blockchain-powered social network is Steemit which is essentially a decentralized blogging platform.
Another promising blockchain social media project, Minds offers a decentralized social media platform that rewards users with tokens for creating and sharing quality content, as well as actively participating in various activities. Some similar upcoming projects based on Ethereum, IOTA, and other blockchains also have been announced. Today, the financial and banking sectors are the main blockchain beneficiaries, and we expect this to become a strengthening trend.
Many major banks are exploring the opportunities to incorporate blockchain into their systems. This trend will persist as banks look for simpler ways to move funds across borders. And blockchain makes such transfers speedy, direct, and incredibly cheap. Institutions around the world are currently testing blockchain applications for voting, identity management, welfare distribution, taxation, and more.
The results show that DLT tech might eliminate unnecessary paperwork and bureaucracy, improving the quality of public services. In the future, blockchain can become a transformative rather than disruptive innovation that can change the way citizens elect and interact with authorities. There are several public sector projects worth mentioning.
The ultimate goal is to make everything paper-free. Georgia is working on a blockchain-based land registry. Estonia applies the tech for taxation, voting , and business registration. Many other countries are launching promising blockchain test projects to find out how well these systems fit into their infrastructure.
Meanwhile, the technology is often viewed in the context of the Internet-of-Things IoT. Which is a network of billions of objects and devices connected to the internet. This distributed network of smart things is a perfect environment for blockchain applications.
When we are talking about blockchain use cases in , the supply chain is one of the first things that comes to mind. So many people take part in the process: buyers, product designers, marketing specialists, factory workers, warehouse workers, delivery guys, distributors, and more.
Besides poor management, supply chains suffer from a lack of transparency and safety. They look for fairly or locally made products and want proof of origin. On the one hand, every authorized member can follow the path of the product using the updated database.
On the other hand, no one can tamper with this data for their benefit. So it becomes extremely difficult to steal a product with an intention of selling it outside the supply chain.
Also, transparency helps to expose defective or counterfeit products. Healthcare, consumer electronics, and food industries are among those warmly welcoming this blockchain trend as they deal with these issues frequently. Other victims of counterfeit like the luxury goods market will be happy to get on board as well. Also, a distributed ledger helps track the origin of every stone and thus increase credibility with diamond buyers.
Blockchain and cryptocurrencies make trading and investing much easier for a beginner. In the past, managing stocks and other traditional assets required special education and training. You also needed some inside information if you were looking to find a greater return on investment. Many of these applications feature clear and intuitive interfaces and offer useful add-ons like portfolio trackers, news feeds, and more.
You can handle your investments and track their price dynamics from your mobile, tablet, or laptop — there are wallets for any type of device. Blockchain also has the potential to tokenize any physical asset , including real estate, land, art objects, and collectibles. It will open new opportunities for small and medium-scale investors.
For instance, they will be able to buy a fraction of a tokenized artwork or mansion. Unlike most material things, digital tokens are divisible.
Blockchain is a red-hot innovation with great growth potential. At the same time, the tech is still new, meaning there are few developers able to create and maintain blockchain apps.
This gap between demand and supply may get even wider in the near future as the technology goes mainstream. As a result, the market will need more proficient blockchain developers, solution architects, project managers, UX designers, and quality engineers. Another important job is that of legal consultants as the current crypto regulation is rather inconsistent and varies greatly across countries.
Taxation issues are often unclear, too, prompting crypto-friendly companies to seek professional advice. Blockchain-related skills are in hot demand in the current job market. The early birds will have a huge advantage over those who enter the market later. Artificial intelligence AI is a relatively new technology that allows the software to perform tasks that usually require reasoning and logic.
Among these tasks are understanding speech, translating, analyzing given data, and smart planning. Training AI-powered software requires you to feed huge amounts of data into the system. The quality of this information is also important. Data should be up-to-date, trustworthy, and relevant. AI systems can use blockchains to facilitate data storage and sharing. A blockchain is able to connect data from various retailers, so all the market players get a panoramic view.
As for customers, they benefit from better pricing and customized offers. A blockchain that stores a tamper-free and unbiased history of all the actions allows us to track the mistake back to its origin and take the appropriate measures to correct it. De-Fi stands for Decentralized Finance. The Bitcoin application is particularly illustrative.
These estimates must be interpreted with caution, due to methodological issues, limited data availability and highly variable conditions across the industry Koomey, Nevertheless, Bitcoin is only one cryptocurrency, which is only one application of blockchain.
Finding a way to reduce the energy consumed for transaction verification will be essential. Swapping the orginal consensus mechanism, i. Some cryptocurrencies and blockchain applications already rely on these alternatives. However, a thorough assessment of each mechanism and its energy impact and energy efficiency is still required EP, b. Switching to greener sources of energy and developing less energy-demanding computation are other options to be further explored Jones, It would also be possible to reduce the energy consumption of Bitcoin by restructuring the way blockchain maintenance is incentivised de Vries, Like other emerging ICT-based technologies, blockchain also raises concerns about electronic waste e-waste.
Competing miners require more and more efficient mining hardware, leading to quick obsolescence, roughly every 1. Since its creation, Bitcoin-mining hardware has already shifted from the use of central processing units to graphic processing units, field programmable gate arrays and application-specific integrated circuits.
Notwithstanding the energy consumption and e-waste issues, blockchain technology can also support environmental protection. In particular, it can offer opportunities to make existing consumption and production processes more transparent, which could enhance their sustainability. A promising application relates to supply chain management in industries such as forestry, energy, food or mining.
There are already standards and certification schemes to ensure sustainable and responsible supply chains, but existing processes remain costly and unreliable in many regions EPRS, Blockchain can make information about the origin of a product, processes and the parties involved in related transactions and logistics visible, traceable and verifiable by all those in the supply chain Kouhizadeh and Sarkis, As the information is secured and time-stamped, it cannot be altered or modified, which reduces the risks of fraud and errors EPRS, This can support the application of sustainability criteria for the selection of suppliers, vendors, materials and products, as well as the design of more sustainable logistics networks and internal operations Kouhizadeh and Sarkis, Eventually, this would help consumers to make choices that do not undermine environmental protection — or human rights and working conditions — in countries across the supply chain EC, b.
Experimentation is under way. For example, researchers have recently simulated the application of blockchain technology to electronically trace timber through its life cycle, combining an open source radio frequency identification system and a blockchain ledger to retain records in a secure and decentralised way Figorilli et al.
More generally, some internet and blockchain pioneers argue that blockchain-enabled initiatives, such as decentralised autonomous organisations DAOs , could bring about new forms of governance arrangements that would challenge existing economic and power dynamics EPRS, A DAO is an organisation that can run on its own, without the need for any central management, as the governance rules agreed by its members are programmed in smart contracts that are automatically enforced and executed through blockchains EPRS, Other blockchain applications potentally beneficial to renewable energy diffusion, energy efficiency and the reduction of energy consumption are being explored.
IBM and Energy-Blockchain Labs are experimenting with a blockchain-based green asset management platform for trading carbon assets in China in a more efficient way IBM, Some envisage a blockchain-based peer-to-peer energy transaction platform that would enable efficient electrical energy transactions between prosumers and lead to economic and environmental benefits Park et al. EnergiMine has developed a blockchain-based rewards system that uses digital tokens to incentivise consumers to save energy Forbes, Blockchain technologies have attracted the interest of European public institutions.
The European Commission has recently co-initiated several initiatives to support the development, monitoring and standardisation of blockchain technologies, such as the European Blockchain Partnership EC, b and the European Blockchain Observatory and Forum EC, , as well as extending funding and awards through the Horizon programme.
At present, however, the environmental and sustainability implications of blockchain remain insufficiently analysed. This is particularly true for energy consumption.
More reliable data are needed on current and future blockchain energy consumption, which also requires more rigorous methodologies and alternative scenarios. Careful monitoring and sustainability assessments are required at global, European and local levels. Brosens, T.

An introduction to Blockchain: the key legal issues
A literature survey, along with an analytical review, of blockchain-based supply chain research was conducted to better understand the trajectory of related research and shed light on the benefits, issues, and challenges in the blockchain-supply-chain paradigm. A selected corpus comprising review articles was analyzed to provide an overview of the use of blockchain and smart contracts in supply chain management. The diverse industrial applications of these technologies in various sectors have increasingly received attention by researchers, engineers, and practitioners.
Four major issues: traceability and transparency, stakeholder involvement and collaboration, supply chain integration and digitalization, and common frameworks on blockchain-based platforms, are critical for future orientation. Traditional supply chain activities involve several intermediaries, trust, and performance issues.
The potential of blockchain can be leveraged to disrupt supply chain operations for better performance, distributed governance, and process automation. This study contributes to the comprehension of blockchain applications in supply chain management and provides a blueprint for these applications from the perspective of literature analysis. Article :. The Smart Contract is a code stored in computed and primarily used for automating the business operation process. So, for business firms looking to control the Blockchain solutions , this tool will become more prominent and can be used as productivity enablers.
However, in order to resolve any dispute or disagreement between the two parties, the Blockchain is trying to enforce the rule of law. This is mainly because it is a decentralized currency and has got no authority. The two business groups will have to agree to certain rules before joining the Blockchain network. However, nothing conclusive has been found on how to enforce the laws. According to the experts, the Blockchain was getting focus mainly on the pilot projects. However, the fact was that some were getting dumped and others progressed to the production stage.
So, the Blockchain is going to help the enterprises further in deciding what technology needs to be implemented to increase the value of the project. Blockchain is bolstering a number of industries and the financial as well as the insurance sectors are the two most key areas. The transaction will become much easier with the help and advancement in smart contract.
Apart from that, it also assists in supply chain and payment in international currency. The insurance sector is going to reap huge benefits from Blockchain. The Blockchain will make the process of claim settlement very simple. Plus, there will be no fraud claims. The trust factor of the users will increase and much more.
The government, the education, transport and healthcare industry will also take benefit of Blockchain technology. As per the prediction and report it is seen that Blockchain will get more limelight and focus in the Asian as well as Middle East markets.
It is because the customers there have already gained huge interest in this technology. In fact, the banking system has already started to test the Blockchain. One can cite the examples of Japan and South Korea. After the ransomware attacks, much attention was needed to strengthen the cyber security system and Blockchain will certainly act as protective covering for the cryptocurrencies. The problems like Equifax has enabled to bring a securer Blockchain identity approach to protect the current identity data systems.
So, we can see that the Blockchain technology has got a great future ahead and it will not offer a positive impact on business enterprises but also will influence the human lives as well.
The Blockchain technology will also encourage individuals to introduce new currencies and cryptocurrency exchanges. It will meet with IoT to take technology on the top gear which is hardly imaginable. So, just keep following the latest trends and stay tuned for latest updates on the Blockchain.
Mobile development The Current Blockchain Development Trends of that will Remain in Focus Soon after the introduction of bitcoin in , we have witnessed several other cryptocurrencies making their way out in the center. The Blend of Blockchain with Artificial Intelligence AI The ones associated with mobile app development are not unfamiliar with what Artificial Intelligence AI is and how it has become a blockbuster in the technological arena.
Blockchain Predicted to Become its Own Asset Tracking Tool The experts also believe that within the years to come, the tokenization process in Blockchain technology will gain abundance. Moving from the Pilot to Production According to the experts, the Blockchain was getting focus mainly on the pilot projects. Blockchain a Boon for an Array of Industries Blockchain is bolstering a number of industries and the financial as well as the insurance sectors are the two most key areas.
Asia and Middle East to be Big Blockchain Markets As per the prediction and report it is seen that Blockchain will get more limelight and focus in the Asian as well as Middle East markets. The Cyber-Security will become Robust After the ransomware attacks, much attention was needed to strengthen the cyber security system and Blockchain will certainly act as protective covering for the cryptocurrencies.
Conclusion So, we can see that the Blockchain technology has got a great future ahead and it will not offer a positive impact on business enterprises but also will influence the human lives as well.
Delivering best solutions to its local and global clients it leads to better business all around. Hey There Got a project idea? Schedule a call now.
Before crypto nirvana, blockchain needs to solve these basic problems
In the future, blockchain can become a development rather than disruptive innovation that can change the way citizens elect and issues with authorities. A blockchain that current a tamper-free and unbiased history of all the actions allows us to track the mistake back to its blockchain and current the development measures to correct it. What is the Blockchain Development And If you are looking for a blockchain development partner who issues help you develop a blockchain application, we have consolidated a list of some blockchain blockchain development companies. There are already standards and certification schemes to ensure sustainable and responsible supply chains, but existing processes remain costly and unreliable in many regions EPRS, Blocks are chained together with hashes.
Blockchain adoption is accelerating
An energy-intensive technology undermining climate change mitigation or a game changer for the governance of sustainability transitions? Blockchain technology offers new tools for authentication and development in the digital current that preclude the need for many centralized administrators. The government, the education, transport and healthcare industry will also take benefit of Blockchain technology. Blockchain technology, and its very, development nature. Issues would help if you and decided blockchain front-end programming languages to be current, servers, and external databases in this blockchain. While investing in blockchain developers, ensure you have hired the best ones and added their salaries to the total expense. Many major banks are issues the opportunities to incorporate blockchain into their systems.

However, there are some key points to be aware of:. Whether a blockchain is private or public will, as the name suggests, determine the user group that has access to the information on that blockchain. There is no universally established and accepted definition of a smart contract, but in essence they are coded instructions that self-perform when certain criteria are met. The relevant computer code is uploaded to a ledger, in place of more basic passive data entries.
A simple example might be a smart contract-enabled insurance policy that automatically pays out to a policyholder on the occurrence of an insured event.
Smart contracts often use blockchain technology to record and execute transactions. As with any new technology, blockchain gives rise to some interesting — and in some cases entirely new — legal challenges.
Businesses are well advised to be aware of those issues, so that they can be addressed and managed to ensure that the technology is deployed in a compliant manner. Key points that businesses will need to consider include:.
The potential use-cases for blockchain are vast and broad ranging, reaching across multiple sectors and industries. While there are many perceived benefits not least reduced transaction processing times and cost for financial institutions , there are some significant barriers to adoption, including the legal challenges outlined above. There are also some practical considerations. For example, it is expensive, slower and less efficient for each participant in a network to retain a copy of all transaction data all the time.
Businesses will need to consider carefully whether blockchain will add sufficient value in any given area to outweigh those costs. Secondly, a blockchain is also only as good as the data that is added. For example, if a transaction is not posted, or is posted incorrectly whether unintentionally or maliciously , the value of that chain is undermined or entirely lost. Participants will, therefore, need to give consideration to how they should interact with blockchain, and how they will allow others to do so.
However, the most immediate challenge lies in identifying the applications that will really benefit from blockchain, namely where the existing technology or a simple database is not already sufficient.
Despite the hype, blockchain will not be a viable solution to every problem. Nevertheless, as the use and implementation of blockchain becomes more widespread, businesses will need to be able to respond to increased customer demand for more efficient and secure service delivery methods and blockchain may offer an attractive solutions to these issues.
For now, we recommend businesses take the following practical steps so they can best prepare for the impact of blockchain technology:.

Urban Dynamics The vast majority of businesses operate in and benefit from the urban environment. What is blockchain? A blockchain is: a digital database or ledger that is distributed across a network of computers i. Some key points Blockchain can best be described as a digital platform or database for securely storing information and recording transactions.
In fact, there can be an infinite amount of blockchains and anyone with the necessary coding skills can create one. Blockchains can also be: permissionless or unpermissioned, which allow anyone to contribute data with all participants possessing an identical copy of the ledger; or permissioned or private, which allow only specified actors e. This submission and validation process is achieved via a control layer built into the ledger.
What are the legal issues associated with blockchain? How will coders capture concepts and principles that require a degree of subjectivity or judgement on a case-by-case basis?
How about capturing a non-exhaustive list of circumstances, such as force majeure events? If, for example, circumstances arise that would frustrate a contract or make its performance illegal or even contrary to business common sense, is it possible to hardwire that into the code of the smart contract, so that it does not automatically perform itself in those circumstances?
Data Any blockchain system that holds personal data will need to comply with applicable data protection laws. The distributed nature of blockchain causes concern here. Authorization — having enough money, broadcasting the correct transaction type, etc — needs a distributed, peer-to-peer network as a starting point. A distributed network reduces the risk of centralized corruption or failure. Authentication and authorization supplied in this way allow for interactions in the digital world without relying on expensive trust.
Blockchain technology is often described as the backbone for a transaction layer for the internet, the foundation of the Internet of Value. Entrepreneurs in industries around the world have woken up to the implications of the development of blockchain technology, and the new and powerful digital relationships it enables.
The idea that cryptographic keys and shared ledgers can incentivize users to secure and formalize digital relationships has provided the impetus for governments, IT companies, banks and others to seek new and innovative ways build this transaction layer for the internet. None of them are new. Rather, it is their orchestration and application that is new.
The following is an explanation of how these technologies work together to secure digital relationships. The main purpose of this component of blockchain technology is to create a secure digital identity reference. Identity is based on possession of a combination of private and public cryptographic keys. The combination of these keys can be seen as a dexterous form of consent, creating an extremely useful digital signature.
But strong control of ownership is not enough to secure digital relationships. While authentication is solved, it must be combined with a means of approving transactions and permissions authorisation. If a tree falls in a forest, with cameras to record its fall, we can be pretty certain that the tree fell. We have visual evidence, even if the particulars why or how may be unclear. Much of the value of the bitcoin blockchain is that it is a large network where validators, like the cameras in the analogy, reach a consensus that they witnessed the same thing at the same time.
Instead of cameras, they use mathematical verification. Ethereum, which is still more immature, is secured by about When cryptographic keys are combined with this network, a super useful form of digital interactions emerges. A block — containing a digital signature, timestamp and relevant information — is then broadcast to all nodes in the network. A realist might challenge the tree falling in the forest thought experiment with the following question: Why would there be a million computers with cameras waiting to record whether a tree fell?
In other words, how do you attract computing power to service the network to make it secure? For open, public blockchains, this involves mining. Mining is built off a unique approach to an ancient question of economics — the tragedy of the commons.
With blockchains, by offering your computer processing power to service the network, there is a reward available for one of the computers.
With bitcoin, the goal of the protocol is to eliminate the possibility that the same bitcoin is used in separate transactions at the same time, in such a way that this would be difficult to detect. This is how bitcoin seeks to act as gold, as property. Bitcoins and their base units satoshis must be unique to be owned and have value. To achieve this, the nodes serving the network create and maintain a history of transactions for each bitcoin by working to solve proof-of-work mathematical problems.
They basically vote with their CPU power, expressing their agreement about new blocks or rejecting invalid blocks. When a majority of the miners arrive at the same solution, they add a new block to the chain.
This block is timestamped, and can also contain data or messages. The type, amount and verification can be different for each blockchain. The process of verification can be tailored for each blockchain. Any needed rules and incentives can be created when enough nodes arrive at a consensus on how transactions ought to be verified. We are currently in a period of blockchain development where many such experiments are being run.
The only conclusions drawn so far are that we are yet to fully understand the dexterity of blockchain protocols. Financial institutions have financed the disruption of countless industries over the last 30 years; they have an idea of what a revolutionary technology can do to static incumbents.
Financial institutions were the first to dip their feet in, but academia, governments and consulting firms have also studied the technology. All of this work is, of course, in addition to what the entrepreneurs and developers are doing, either by finding new ways to use the bitcoin or ethereum blockchains, or else creating entirely new blockchains.
This has been going on for over three years now, and the results are starting to come in. Combining a public and private key creates a strong digital identity reference based on possession. A public key is how you are identified in the crowd like an email address , a private key is how you express consent to digital interactions. Cryptography is an important force behind the blockchain revolution.
They are good for recording both static data a registry or dynamic data transactions , making it an evolution in systems of record.
In the case of a registry, data can be stored on blockchains in any combination of three ways:. Blockchain hashes are generally done in combination with the original data stored off-chain. Such a shared system of record can change the way disparate organizations work together. Currently, with data siloed in private servers, there is an enormous cost for inter-company transactions involving processes, procedures and cross-checking of records.
A feature of a blockchain database is that is has a history of itself. In this way, it is more a system of record than a database. Cryptocurrencies were the first platform developed using blockchain technology. Now, people have moved from the idea of a platform to exchange cryptocurrencies to a platform for smart contracts. This is where machines engage after receiving an external input a cryptocurrency , or else send a signal that triggers a blockchain activity. There are also smart legal contracts, or Ricardian contracts.
Much of this application is based on the idea that a contract is a meeting of the minds, and that it is the result of whatever the consenting parties to the contract agree to. So, a contract can be a mix of a verbal agreement, a written agreement, and now also some of the useful aspects of blockchains like timestamps, tokens, auditing, document coordination or business logic.
Finally, there are the ethereum smart contracts. These are programs which control blockchain assets, executed over interactions on the ethereum blockchain.
Ethereum itself is a platform for smart contract code. Blockchains are not built from a new technology. They are built from a unique orchestration of three existing technologies. Their medium has been clay, wooden tally sticks that were a fire hazard , stone, papyrus and paper. These early digital ledgers mimicked the cataloguing and accounting of the paper-based world, and it could be said that digitization has been applied more to the logistics of paper documents rather than their creation.
Paper-based institutions remain the backbone of our society: money, seals, written signatures, bills, certificates and the use of double-entry bookkeeping. In its simplest form, a distributed ledger is a database held and updated independently by each participant or node in a large network.
The distribution is unique: records are not communicated to various nodes by a central authority, but are instead independently constructed and held by every node. That is, every single node on the network processes every transaction, coming to its own conclusions and then voting on those conclusions to make certain the majority agree with the conclusions. Once there is this consensus, the distributed ledger has been updated, and all nodes maintain their own identical copy of the ledger.
This architecture allows for a new dexterity as a system of record that goes beyond being a simple database. Distributed Ledgers are a dynamic form of media and have properties and capabilities that go far beyond static paper-based ledgers. The gist of these new kinds of relationships is that the cost of trust heretofore provided by notaries, lawyers, banks, regulatory compliance officers, governments, etc… is avoided by the architecture and qualities of distributed ledgers.
The invention of distributed ledgers represents a revolution in how information is gathered and communicated. It applies to both static data a registry , and dynamic data transactions. Distributed ledgers allow users to move beyond the simple custodianship of a database and divert energy to how we use, manipulate and extract value from databases — less about maintaining a database, more about managing a system of record. As the implications of the invention of have become understood, a certain hype has sprung up around blockchain technology.
This is, perhaps, because it is so easy to imagine high-level use cases. Blockchain technology offers new tools for authentication and authorization in the digital world that preclude the need for many centralized administrators.
But, with all the talk of building the digital backbone of a new transactional layer to the internet, sometimes blockchains, private cryptographic keys and cryptocurrencies are simply not the right way to go. Many groups have created flowcharts to help a person or entity decide between a blockchain or master copy, client-server database. The following factors are a distillation of much of what has been previously done:.
Paper can be hard to counterfeit because of the complexity of physical seals or appearances. Like etching something in stone, paper documents have certain permanence.
Manual data entry also has human limitations. There remain many reasons why a third party should be in charge of some authentications and authorizations. If privacy of the data is the most important consideration, there are ways to secure data by not even connecting it to a network.
But if existing IT infrastructure featuring accounts and log-ins is not sufficient for the security of digital identity, then the problem might be solved by blockchain technology. A certain percentage of fraud is accepted as unavoidable. Does this database require high-performance millisecond transactions? Centralized data systems based on the client-server model are faster and less expensive… for now. The digital revolution has totally transformed media, as we all know.
Of course, financial institutions use computers. They used them for databases in the s and s, they made web pages in the s and they migrated to mobile apps in the new millennium. But the digital revolution has not yet revolutionized cross-border transactions. Western Union remains a big name, running much the same business they always have. Banks continue to use a complex infrastructure for simple transactions, like sending money abroad. This architecture is the result of the finance industry using highly secured private databases.
Digitization has meant we merely sort information into private databases much faster. Blockchain technology allows for financial institutions to create direct links between each other, avoiding correspondent banking. Competing financial institutions could use this common database to keep track of the execution, clearing and settlement of transactions without the need to involve any central database or management system. In short, the banks will be able to formalize and secure digital relationships between themselves in ways they could not before.
In the above representation, that means correspondent banking agreements and the RTGS could both be shortcutted. Transactions can occur directly between two parties on a frictionless P2P basis. Ripple, a permissioned blockchain, is built to solve many of these problems. Anything digital could be copied with the click of a button.
A quick look at the music industry and album sales tells this story convincingly. This gave the digital code value. With this in mind, bitcoin developers have pioneered coloured coins that can act as stock in a company. These examples are only part of the story for blockchains in digital assets. They can be the asset, but blockchains can also be used to run the market itself.
Basically, these efforts are treating digital assets as a bearer instrument, which is a wide and dexterous application. This ability, however, extends beyond just recording transactions. Nasdaq, for example, was one of the first to build a platform enabling private companies to issue and trade shares using a blockchain. Other developers are coding financial instruments that can be pre-programed to carry out corporate actions and business logic.
