This computer is connected to other computers via an being network. In addition, contrary to the use of relational norms, blockchains do not require trust or direct blockchain between collaborators. Even a small action can make an enormous difference when millions of people do it!
Importantly, such digital platforms are likely to exhibit network effects. That is, digital networks of energy providers and consumers are likely to become more valuable to their users as they gain more users and, at some point, an expanding energy network may prevent competitors from entering the market. Accordingly, pioneering energy platforms may have a head start to dominate energy-related industries through the power of network effects.
The database of the U. Patent and Trademark Office USPTO suggests that energy-related blockchain patent application filings have continued to increase since the first of such applications was filed in Nevertheless, the energy-related blockchain patent landscape is currently not a crowded one.
Thus, the time is ripe for energy innovators to claim valuable patent rights. Patent owners may use patents defensively and offensively to gain an edge over competitors and realize significant business value.
A defensive approach to patenting allows patent owners to benefit without suing. For example, patents can deter competitors from copying and encourage them, instead, to seek a licensing agreement or focus their research efforts elsewhere.
An offensive approach to patenting allows patent owners to enforce their rights through litigation in a federal district court, or at the U. As importantly, the ITC provides a quicker process than the courts and is able to stop patent infringers from importing infringing products or services into the U.
To adequately benefit from patent ownership, a patent application must be prepared to overcome the statutory hurdles to patentability, without giving up valuable scope of protection. Software-based technologies, like blockchain technology, are often rejected under the subject matter eligibility hurdle of the U. Patent Law 35 U. For example, patent claims describing a method of renewable energy trading using IoT sensors, processors, and memory to autonomously measure, record, and analyze energy supply and usage data through a blockchain ledger may be rejected by the USPTO based on the grounds that they are directed to a method of organizing human activity that is, measuring, recording, and analyzing energy data may be considered as organizing human activity or a fundamental economic practice.
Furthermore, the USPTO may reason that merely recording and analyzing energy-related data through a generic blockchain ledger provides no practical application of the fundamental economic practice and that the recitation of generic IoT sensors and computer hardware does not provide an inventive concept beyond the fundamental economic practice. This approach would help ensure that the patent claims are not drafted to preempt all future technological improvements, but to focus more reasonably on the relevant technological area of invention.
For example, claims incorporating features of an energy-specific data structure to be stored in a blockchain to improve the processing of transactions would likely remove the claims from the abstract idea realm, because the invention would not threaten to preempt virtually all applications of blockchain technology as applied to energy trading. Furthermore, inventions that improve the functionality of blockchain technology itself may avoid or overcome a rejection under 35 U. That is, improvements to distributed storage, distributed processing, cryptography, security and authentication, data structures, and data exchange protocols would not likely be interpreted as being directed to an abstract idea.
This computer is connected to other computers via an online network. So imagine a computer with Bitcoin processing software on it connected to the Internet, which allows the computer to connect to a network of other computers online with Bitcoin processing software. This is where the word distributed or decentralized ledger comes from. Since every transaction is saved on every node or computer with Bitcoin client software on the Bitcoin network, the ledger of all Bitcoin transactions is described as distributed.
So if you have a laptop with Bitcoin client software and keep it connected to the Internet and the Bitcoin network, you will have the entire Bitcoin transaction ledger saved on your computer. So if your computer breaks it will not affect the ledger because the same ledger is being distributed on several other computers around the world. So the network cannot be taken down at any specific point All of these computers process and record blocks of transactions to this public ledger that is saved on all the nodes connected to the Bitcoin network.
The blockchain process creates unique hashes for each transaction, as I mentioned before, that functions to make transactions secure and private. These hashes, as well as time stamps and other unique identifiers, are created for each transaction and recorded on the public ledger. So on to the next question. How else can we utilize blockchain technology besides facilitating digital currency transactions as it does for Bitcoin?
There are several applications for blockchain technology in multiple types of industries. Blockchain technology creates transparency, validates and secures records, manages smart contracts, and eliminates middlemen or third parties.
Some examples of how blockchain could be used include recording land record transactions or mortgages, maintaining digital smart contracts like wills or promissory notes, managing digital identities like passports or birth certificates, housing distributed cloud networks to store information like documents or media, and a myriad of other exciting things.

Auto Loan Pre-approval. What is Blockchain and Why was it Developed? A Simple Explanation. On the other hand, hiring freelance blockchain developers could be less expensive but very risky. Working with a third-party company could be a viable option if your project is enormous. Blockchain companies are experienced and can help you at every step of the development process. When compared to an in-house development team, the cost of blockchain companies is lower.
Every business requires a digital solution to run their business operations efficiently. Building a blockchain app can build trust and offer transparency while removing additional intermediaries. Before implementing blockchain technology and estimating its cost, it is essential to understand the type of blockchain app you need.
Whether you need a permissioned blockchain app or a permissionless blockchain app, you need to consider which application can suit your business needs. Also, the cost of a blockchain application varies from industry to industry. For example, you may need an app for supply chain management, healthcare, real estate, education, and many other business domains. The cost of an app will depend on the complexity of the project.
The cost of blockchain app development also depends on the number of resources required to develop an application. Salaries of blockchain experts are the significant expenses you should not miss when calculating the cost to build an app.
While investing in blockchain developers, ensure you have hired the best ones and added their salaries to the total expense. Companies might use agile methodology tools such as Jira, Confluence, and Trello to manage blockchain projects. They use such tools to test an app, track timelines, and deliverables. Therefore, the price of project management tools is also added to the cost of blockchain implementation. Your blockchain app might require a subscription to third-party subscription tools such as bug tracking tools, notification services, amazon web services, software monitoring services, and data analytics tools.
The cost of subscription tools also contributes to the cost of blockchain app development. In this section, we have explained the process of building a blockchain-based application. First of all, it is essential to develop a problem statement and understand all of the issues you want to solve with a proposed solution. Ensure that the blockchain solution will benefit your business abilities.
Analyze whether you need to migrate your current solution to the blockchain, or you require a new application to be developed from scratch. For example, suppose you are a healthcare provider who wants to develop a blockchain-based health record exchange app. In that case, you should know various use cases of the applications and what benefits it will offer to users. Once you decide that you need a blockchain solution for your business operations, the next step is to select the right blockchain platform and blockchain development tools for your project.
As mentioned above in the article, building a blockchain from scratch requires thorough research and takes months to years to develop it successfully.
Therefore, you should build a blockchain app on top of a blockchain platform that meets your business requirements. You should identify the right blockchain platform for your application based on the factors like consensus mechanism and problems you want to solve.
For example, you can build an Ethereum-based application to develop a decentralized public application with smart contracts. When the blockchain platform is identified, you must do brainstorming and understand the exact business needs. Once you identify the blockchain platform for developing a blockchain application, you should focus on drafting business requirements and brainstorming ideas. Find what technology components should be added as off-chain or on-chain entities on the blockchain ecosystem.
Create a roadmap of the product that will help you to build an application within a decided deadline. You should come up with a blockchain model and conceptual workflow of the blockchain application. Also, decide if the application needs to be developed on a permissioned or permissionless blockchain network. It would help if you also decided on front-end programming languages to be used, servers, and external databases in this stage.
A proof of concept is done to represent the practical applicability of a blockchain project. It can be either a design prototype or a theoretical build-up. In Theoretical Build-up, each project requires theoretical cases so that users could understand the applicability and viability of the product. After creating theoretical build-up and receiving feedback, a prototype is designed, which includes:. When the client approves the PoC, the next step is to prepare technical and visual designs for the application.
Since you have planned an entire application at this stage, start creating UIs for each software component. Designs APIs that will be integrated with user interfaces to run an application at the back-end. Once the admin consoles and user interfaces are designed, the application gets ready for development. Development is the significant phase of the blockchain development process, where you should be ready to build the blockchain app. In this specific stage, you either have to develop or integrate APIs for particular use cases of the application.
The application is built under multiple versions. Once the client approves it, the application moves to the next stage, i. But, the software might not comprise all the features at this stage. After the alpha version is released, the app is prepared for the beta version. During Beta Phase, the software application has the complete feature set but with some unknown bugs.
Developers share the beta version with a particular group of people outside the organization to test its functionality. Once the beta version is approved and tested, the application moves to the Release Candidate version, which is an advanced beta version that is ready to be a final application and can be launched. After thorough testing, the application moves to the production phase and gets ready for delivery. Before an app goes live, you should deploy it on the test network to carefully test its functionalities.
When deploying an application, administrators can also manage which versions of the app need to be deployed to various resources with provisioning. Once an application is provisioned, it needs to be hosted on the main chain. If your blockchain app is a hybrid solution, i. The application should be able to upgrade according to any new business needs and prioritization.
For instance, if you need to upgrade the smart contract, later on, you should be able to deploy the new contracts without any difficulty. Developing and deploying an app does not mean you are done. Instead, a software application needs to be maintained post-development to ensure that it works with all types of upgrades in the future.
An Ethereum client, Geth, is used to run Ethereum nodes in the Go programming language. Using Geth, users can mine Ethers, create smart contracts and run them on EVM, explore the block history and send tokens between addresses. Geth can be downloaded and installed on Linux, Windows and Mac.
It supports two types of installations, Scripted and Binary. Once you start using the Geth, you either have an option to create your own blockchain based on the provided settings or connect to the existing blockchain. Remix IDE is a compiler used for small contracts. It is a browser-based tool used to create and deploy smart contracts. You can use Remix IDE to write, debug, test and deploy smart contracts using the Solidity programming language.
Remix can connect to the Ethereum blockchain via Metamask. Before using Ethereum, you should have a place to store Ether tokens and execute smart contracts. Mist is the Ethereum wallet used for smart contract deployment and is available for Mac, Windows and Linux.
While installing Mist, remember once you set up the password, you cannot update it again. Create a strong password and never forget it. It allows users to make calls to the blockchain without the need to run an Ethereum node. GanacheCLI is used for the instant mining of transactions. It is an easy-to-use API that provides you with an overview of test chain events. Security plays a prominent role when it comes to building a blockchain application.

Cardano tops Ethereum by number of GitHub commits
Margaret Sandoval Now back to hashes. Now the output of the hash function is a fixed form of data, just like a social security number, and this output is commonly known as a hash value, hash code, digest, or simply a hash. And the child blocks stemming from this represent states, and a child block stemming from that represents cities.
Onto the next question. It was made by an anonymous person or group that goes by the pseudonym, Satoshi Nakamoto. A common misconception is that bitcoin is synonymous with blockchain. That, however, is not the case. The blockchain facilitates the secure and private transfer of the digital currency called Bitcoin, as well as posts the transactions to a public ledger to maintain data integrity Right now most financial transactions are facilitated and recorded through the use of private parties such as banks, Visa, MasterCard, and other financial institutions.
The blockchain foundation allows Bitcoin currency transactions to occur securely and privately while maintaining the accuracy of the transactions by posting a time-stamped unmodifiable record of the transaction to a public ledger without the use of a third party. Instead, it uses computers, mathematical algorithms, and cryptology to perform these functions Which allow a direct connection between the Bitcoin users by removing the need for a third party. So again imagine a list of transactions as a block and each block is being recorded on a public ledger So as blocks of transactions are recorded on a running ledger, it creates a chain of blocks Hence the term blockchain.
Every transaction between Bitcoin users is processed by a computer that has a Bitcoin processing software on it called Bitcoin client. This computer is connected to other computers via an online network.
So imagine a computer with Bitcoin processing software on it connected to the Internet, which allows the computer to connect to a network of other computers online with Bitcoin processing software. This is where the word distributed or decentralized ledger comes from. Since every transaction is saved on every node or computer with Bitcoin client software on the Bitcoin network, the ledger of all Bitcoin transactions is described as distributed.
So if you have a laptop with Bitcoin client software and keep it connected to the Internet and the Bitcoin network, you will have the entire Bitcoin transaction ledger saved on your computer.

From greater user privacy and heightened security to lower processing fees and fewer errors, blockchain technology may very well see applications beyond those outlined above.
But there are also some disadvantages. Provides a banking alternative and way to secure personal information for citizens of countries with unstable or underdeveloped governments. Here are the selling points of blockchain for businesses on the market today in more detail. Transactions on the blockchain network are approved by a network of thousands of computers. This removes almost all human involvement in the verification process, resulting in less human error and an accurate record of information.
Even if a computer on the network were to make a computational mistake, the error would only be made to one copy of the blockchain. Typically, consumers pay a bank to verify a transaction, a notary to sign a document, or a minister to perform a marriage.
Blockchain eliminates the need for third-party verification and, with it, their associated costs. Bitcoin, on the other hand, does not have a central authority and has limited transaction fees. Blockchain does not store any of its information in a central location. Instead, the blockchain is copied and spread across a network of computers. Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change.
By spreading that information across a network, rather than storing it in one central database, blockchain becomes more difficult to tamper with. If a copy of the blockchain fell into the hands of a hacker, only a single copy of the information, rather than the entire network, would be compromised. Transactions placed through a central authority can take up to a few days to settle. If you attempt to deposit a check on Friday evening, for example, you may not actually see funds in your account until Monday morning.
Whereas financial institutions operate during business hours, five days a week, blockchain is working 24 hours a day, seven days a week, and days a year.
Transactions can be completed in as little as ten minutes and can be considered secure after just a few hours. This is particularly useful for cross-border trades, which usually take much longer because of time-zone issues and the fact that all parties must confirm payment processing.
Although users can access details about transactions, they cannot access identifying information about the users making those transactions. It is a common misperception that blockchain networks like bitcoin are anonymous, when in fact they are only confidential. That is, when a user makes public transactions, their unique code called a public key , is recorded on the blockchain, rather than their personal information.
Once a transaction is recorded, its authenticity must be verified by the blockchain network. Thousands of computers on the blockchain rush to confirm that the details of the purchase are correct.
After a computer has validated the transaction, it is added to the blockchain block. Each block on the blockchain contains its own unique hash, along with the unique hash of the block before it. This discrepancy makes it extremely difficult for information on the blockchain to be changed without notice.
Most blockchains are entirely open-source software. This means that anyone and everyone can view its code. This gives auditors the ability to review cryptocurrencies like Bitcoin for security. Because of this, anyone can suggest changes or upgrades to the system. If a majority of the network users agree that the new version of the code with the upgrade is sound and worthwhile then Bitcoin can be updated.
Perhaps the most profound facet of blockchain and Bitcoin is the ability for anyone, regardless of ethnicity, gender, or cultural background, to use it. According to the world bank there are nearly 2 billion adults that do not have bank accounts or any means of storing their money or wealth. These people often earn little money that is paid in physical cash.
They then need to store this physical cash in hidden locations in their homes or places of living leaving them subject to robbery or unnecessary violence. Keys to a bitcoin wallet can be stored on a piece of paper, a cheap cell phone, or even memorized if necessary. For most people, it is likely that these options are more easily hidden than a small pile of cash under a mattress.
Blockchains of the future are also looking for solutions to not only be a unit of account for wealth storage, but also to store medical records, property rights, and a variety of other legal contracts. While there are significant upsides to the blockchain, there are also significant challenges to its adoption. The roadblocks to the application of blockchain technology today are not just technical. The real challenges are political and regulatory, for the most part, to say nothing of the thousands of hours read: money of custom software design and back-end programming required to integrate blockchain to current business networks.
Here are some of the challenges standing in the way of widespread blockchain adoption. Although blockchain can save users money on transaction fees, the technology is far from free. In the real world, the power from the millions of computers on the bitcoin network is close to what Denmark consumes annually.
Despite the costs of mining bitcoin, users continue to drive up their electricity bills in order to validate transactions on the blockchain. When it comes to blockchains that do not use cryptocurrency, however, miners will need to be paid or otherwise incentivized to validate transactions. Some solutions to these issues are beginning to arise.
For example, bitcoin mining farms have been set up to use solar power, excess natural gas from fracking sites, or power from wind farms. Bitcoin is a perfect case study for the possible inefficiencies of blockchain. Although other cryptocurrencies such as Ethereum perform better than bitcoin, they are still limited by blockchain.
Legacy brand Visa, for context, can process 24, TPS. Solutions to this issue have been in development for years. There are currently blockchains that are boasting over 30, transactions per second. While confidentiality on the blockchain network protects users from hacks and preserves privacy, it also allows for illegal trading and activity on the blockchain network. The website allowed users to browse the website without being tracked using the Tor browser and make illegal purchases in Bitcoin or other cryptocurrencies.
Current U. This system can be seen as both a pro and a con. It gives anyone access to financial accounts but also allows criminals to more easily transact.
Many have argued that the good uses of crypto, like banking the unbanked world, outweigh the bad uses of cryptocurrency, especially when most illegal activity is still accomplished through untraceable cash.
Many in the crypto space have expressed concerns about government regulation over cryptocurrencies. While it is getting increasingly difficult and near impossible to end something like Bitcoin as its decentralized network grows, governments could theoretically make it illegal to own cryptocurrencies or participate in their networks.
Over time this concern has grown smaller as large companies like PayPal begin to allow the ownership and use of cryptocurrencies on its platform. First proposed as a research project in , blockchain is comfortably settling into its late twenties.
With many practical applications for the technology already being implemented and explored, blockchain is finally making a name for itself at age twenty-seven, in no small part because of bitcoin and cryptocurrency.
As a buzzword on the tongue of every investor in the nation, blockchain stands to make business and government operations more accurate, efficient, secure, and cheap with fewer middlemen.

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. EP, b, European Parliament resolution of 3 October on distributed ledger technologies and blockchains: building trust with disintermediation www. Figorilli S. Goldfeder, S. Jones, B.
