Some other countries such as China, sometimes show favor toward them and some other time not so much. South Korea is precisely analyzing the cryptocurrency markets and Blockchain networks in order to organize proper measures and stances in the future.
Different financial and economic institutes and academic and research centers are analyzing and evaluating the capacities of new technologies. Thailand and the Philippines also want to evaluate and observe the capacities and opportunities of these new infrastructures. In the Middle Eastern countries, the talk of cryptocurrencies has no place among Arabs. These countries that are under political pressure and are engaged in different wars, seemingly, do not have the opportunity for addressing matters such as cryptocurrencies and Blockchain.
New technologies with all the amazing capacities that have with them, also create some problems that if go unaddressed, not only will there be no development, but also they will lead to some serious problems. They will provide a decentralized blockchain that can be accessible by the customers as well as the wholesalers. Blockchain is perfect for boosting efficiency for your company.
Learn about the blockchain implementation strategy now! Using blockchain in the pharmaceutical supply chain comes with a lot of benefits. Pharma supply chain is one of the biggest concerns for pharmaceutical companies. The challenge is not only to manage the supply chain effectively but also to comply with the standard.
It can —. Drugs always require multiple parameters to be tracked. This includes capturing information such as air quality, humidity, temperature range, and so on. If one of those parameters are not maintained, the drug can go bad and might not be useful for the end-user. One of the best examples is vaccines. They require a carefully operated environment throughout their journey in the supply chain. Blockchain can help solve the said problem by integrating with the supply chain and IoT.
The supply chain can be fitted with devices that track the humidity, temps, and other vital factors. Once recorded, one can send it easily to the concerned parties so that they can take the necessary step when required. It solves the problem of managing a separate ledger and then trying to synchronize them. Blockchain is equally useful for adding governance and compliance with the supply chain. Blockchain also offers smart contracts. Smart contracts offer the ability to automate tasks on the blockchain.
This is very useful as the smart contracts can execute notifications if the compliance conditions are not met. Once done, all the parties relevant to the drug will be notified. Want to check out more blockchain use cases? As blockchain can store information about patients, it can also provide ways to improve clinical trials. The companies can use the blockchain as a way to communicate with the patients and help them get information about every step of the clinical trial process.
This reduces the panic among patients and helps them understand the risks better. The clinical trial protocols are also more transparent for both the stakeholders and the patients. This is a critical step considering that it is always hard to provide a satisfactory and rigorous way to carry out the informed consent process. The consent forms can be verifiable with a proper time-stamp. Also, no one can tamper with the information once stored. Clinical trial data reliability and quality will also improve with blockchain integration.
The decentralized nature lets the clinical labs use a transparent, immutable data source where it is not possible to hamper the data. The clinical trial data is stored in the public blockchain, where you can verify the data whenever needed. It is tamper-proof, and the clinical labs can completely trust the data to carry out the results of their trials. The pharmaceutical companies can also use the system to convince more patients and help them participate in the trials.
More so, pharmaceuticals can also track and trace the data using the tech. With proper integration with the supply chain, pharmaceutical companies can manage their inventories better.
The inventory can also be automated to create triggers when there is a supply or demand scenario. For instance, if there is a spike in demand, then it can simply alert the system on demand, requesting more drug production.
It will also give proper visibility of wholesalers and how their inventory is performing in different circumstances. More so, pharmaceuticals can also track and trace every stage using the tech. The current pharmaceutical industry is patient-centric.
Also, if you are a patient who has an underlying disease, your doctor has a higher chance of going through a patient-centric treatment. Blockchain can help with the patient-centric approach and help pharmaceutical companies track the patients through the blockchain. To make sure patients get the right guidance, the pharma companies need to make partnerships with the medical community.
With that, they can directly take feedback from the patients and then use those data and knowledge to figure out the communicating value and justifying price. Blockchain can not only help through the process but also facilitate the process of connecting to the patients.

Connector actions require a trigger. You can use an Ethereum Blockchain connector action as the next step after a trigger, such as an HTTP request trigger for a microservice. Depending on the action you chose, provide the following details about your smart contract function.
After selecting a smart contract function name, you might see required fields for function parameters. Enter the values or dynamic content required for your scenario. You can now use your logic app.
When the logic app event is triggered, the Ethereum Blockchain action runs. For example, an HTTP request trigger runs an Ethereum blockchain action to query a smart contract state value. This query results in an HTTP response that returns the value. Four scenarios are available:. To generate a logic app based on a smart contract, you need a Truffle solution for the smart contract. You also need a connection to your Azure Blockchain Service consortium network.
For example, the following steps generate a REST-based microservice logic app based on the quickstart HelloBlockchain smart contract:. In the Visual Studio Code explorer sidebar, expand the contracts folder in your solution. Right-click HelloBlockchain. Enter the contract address. For more information, see Get the contract address. The logic app configuration and code files are generated in the generatedLogicApp directory. There's a logic app JSON file for each smart contract function, event, and property.
In your logic app, select Logic app code view. The logic app includes the basic steps for the scenario. However, you need to update the configuration details for the Ethereum Blockchain connector. The cURL command returns a response from the logic app. In this case, the response is the output from the RequestMessage smart contract function. For more information about using the development kit, see the Azure Blockchain Development Kit for Ethereum wiki page.
You can use the API connector for multiple logic apps. Some properties are required and others depend on your scenario. A private key or account address and password are required for creating transactions on a blockchain.
Only one form of authentication is needed. You don't need to provide both the private key and account details. Querying contracts does not require a transaction. If you are using actions that query contract state, the private key or account address and password are not required.
To help you set up a connection to an Azure Blockchain Service member, the following list has possible properties you might need depending on your scenario. Go to your Azure Blockchain Service member. Select Transaction nodes and the default transaction node link. You can use the Ethereum account's private key to authenticate when sending a transaction to the blockchain. Your Ethereum account's public and private keys are generated from a word mnemonic.
You can get the endpoint address by using the development kit extension. You can use the member account and password to authenticate when you send a transaction to the blockchain. The password is set when you create the member. For more information on the account address and password, see Ethereum account.
The contract ABI defines the smart contract interfaces. It describes how to interact with the smart contract. You can also get it from the contract metadata file created by the Solidity compiler. If you used the development kit or Truffle to build your smart contract, you can use the extension to copy the contract ABI to the clipboard.
Right-click the contract metadata JSON file. The file name is the smart contract name followed by the. The contract bytecode is the compiled smart contract executed by the Ethereum virtual machine. You can also get it from the Solidity compiler.
If you used the development kit or Truffle to build your smart contract, you can use the extension to copy the contract bytecode to the clipboard. The contract address is the smart contract destination address on the Ethereum blockchain. You use this address to send a transaction or query state of a smart contract.
You can get the contract address from the Truffle migration output or the contract metadata file. Truffle displays the contract address after deployment of the smart contract. Copy the contract address from the output.

But generic applications backlog is huge and hence makes the exclusivity principle hard to maintain.
With each passing day, customers are getting smarter and more knowledgeable. Their demands as a customer are getting more and more. As the data is accessed from different sources using different models and structures, the data analytics part becomes very time consuming and resource-heavy. The companies need first to make sure that the data they gathered is fresh and insightful before they can start doing data analysis on them.
They also need to make sure that they use ground-breaking data analytics tools to find out what they are looking for. One of the biggest challenges of the pharma industry is to maintain the supply chain. The pharma supply chain is complex and risky. Any compromised supply chain means that the pharma company loses tons of money due to fraud and counterfeit drugs. In the last decade or so, the scientific community at pharma has not done anything extraordinary.
The output rate has remained the same, which leads to the belief that the process of discovering and development is fundamentally flawed. If you compare it with other research industries, then the pharma industry scientific research is nowhere compared to them. The last challenge the pharma industry is suffering from is stagnation.
It is because of no change in the strategies, management culture, and mental models. Almost every industry out there has changed in terms of management culture and process. However, health care and pharmaceuticals seem to suffer from cut thought competition, which is beyond the control of many pharma competitions out there. Blockchain is a new technology that holds the key to all those challenges. Some challenges are beyond the capacity of blockchain; however, it does impact them indirectly.
It utilizes a consensus model to reach consensus for the transactions and other activities that are carried out in the network.
Blockchain networks are also immutable, secure, and transparent. Blockchain can modernize the pharma industry as it introduces three important elements in the industry: privacy, transparency, and traceability.
It can also help pharma to track and trace drugs using blockchain. For instance, clinical trials will benefit hugely due to access to more transparency and correct information. There are other use-cases where blockchain shines, and to get a better understanding, we need to go through the key use-cases of blockchain in pharma and how it can track and trace.
Pharmaceutical companies have to deal with the returned drugs periodically. This happens because of overstocking by the wholesalers. But, the biggest issue is that the returns are comprised of counterfeit drugs. A centralized authority does it at least in the EU. But doing so can mean involving another vendor that controls the authentication of the drugs. In the USA, there is a lack of a centralized database regulator.
The solution is to utilize a decentralized blockchain. By doing so, the pharmaceutical manufacturers can easily record the package serial number on blockchain. This means that the drug can be verified from anywhere. Blockchain pharmacy is the start of a new era.
It gives the customers and wholesalers the ability to check authenticity without the need to depend on a centralized authority. They will provide a decentralized blockchain that can be accessible by the customers as well as the wholesalers.

But what exactly is a blockchain? A blockchain is a database that is shared across a network of computers. Once a record has been added to the chain, it is quite difficult to change. To ensure that all the copies of the database are the same, the network makes constant checks. So why do we need blockchain? Blockchain is a safe way to record activities and keep data fresh while maintaining a record of its history compared to the traditional records or databases where hacks, errors, and downtimes are very possible.
Because the whole blockchain is duplicated across many computers, any user can view the entire blockchain. Transactions or records are processed not by one central administrator, but by a network of users who work to verify the data and achieve a consensus. Applications that use blockchain are called dApps Decentralised Applications. So, when would it make sense to consider using blockchain for our applications, rather than a standard database or record? Now, we have seen quite a number of the advantages of using blockchain, but when should we not bother using a blockchain at all?
Bitcoin which is a cryptocurrency is one popular example of a blockchain, a popular blockchain that has been on the rise aside from bitcoin cryptocurrency is Ethereum blockchain. Bitcoin focuses on cryptocurrencies while Ethereum focuses more on smart contracts which have been the major driving force for the new tech platforms. Recommended reading : Bitcoin vs. The ultimate goal is to get a good understanding of how dApps and Blockchain platforms are being built.
Most dApps have similar architecture and structure. Basically, we have a user that interacts with the dApp frontend — either web or mobile — which then interacts with the backend APIs. The backend, then, on request interacts with the smart contract s or blockchain through public nodes; these either run Node. There are still so many things in between these processes from choosing to build a fully decentralized application or semi-decentralized application to choosing what should be decentralized and how to safely store private keys.
We will be building this with Node. Here are some tools that we should have at our disposal for building or working with Ethereum and Node. When we want to create a new Node. As you probably know, npm stands for Node Package Manager , and it comes prepackaged with the Node. We open the terminal in that folder directory, and then run the following command:. This starts up the project with a package. Then we also create a server. After all these, you will have to install packages that we need to make our build easy and straightforward.
This process is a continuous one, i. If you want to install all of them at once, run the following code in your Terminal:. The -g flag is to store this particular package globally, so that we can use it in any project we are going to work on. We then create an.
We do so by running touch. The dotenv package exports our stored variable to the Node. Next, we have to add scripts for build and development phases of our project in our package. Currently our package. Next, we have to initialize Truffle for use in our smart contract by using the Truffle package we installed globally earlier.
In the same folder of our projects, we run the following command below in our terminal:. Then we can start writing our code in our server. Our server. Our example server. Basically, above we import the libraries that we need with require , then add a middleware that allows the use of JSON in our API using app. After this, we call the function and import it from the routes file. Finally, we listen for any attempted connections on port This server.
Notice that we imported routes. This file will hold the route endpoints for our API. We also imported the packages we needed to use in the server. Then we write our route functions in our routes. We utilize the database storage and retrieval features, and then make sure we export the route function at the end of the file to make it possible to be imported in another file or folder.
Inside this route function, we have many other functions called within both the app and db parameters. Ultimately we choose one of these functions to be executed and provide results as response to incoming requests. In this routes function, we used the get and post operations. We use post for registration, login, and upload operations, and get for accessing the data operations. In the code above, we can also see some database operations like in the register route. We stored the email of a new user with db.
Now, before we can do all of it, we need to name a collection or table with the db. The data we want to store is the music file data, meaning that we have to upload the music to IPFS, then store the address of the buffer in a blockchain. First, we create a new file in the contract folder and name it Inbox.
Before we talk about the functions, we can see that we had to define a contract first called Inbox. Inside this class, we have structures used in the ipfsInbox object first events, then modifiers.
All changes can be easily traced as each new block in the chain is time-stamped. This matters because some authors of open educational resources express fear of not being attributed or being plagiarized.
This fear is reduced with the use of blockchain, because the blocks in the chain cannot be altered. The original creator can always be determined, no matter how much a resource is changed. Adaptations require the creation of a new block that is automatically linked to the original.
The block-encapsulated open educational resources are incorruptible. When every block in the iteration of a resource is time-stamped and recorded, plagiarism becomes obsolete. The tracing features of blockchain allow authors to see if or when their work is being misused and allows them to challenge any improper usage. Transactions cannot be hidden, and so every adaptation of the original source is traceable.
New versions of the source can be uploaded. Trackability is maintained as each block or ledger is distributed on the network. This means that resources created with blockchain will have permanence online that preserves all content adaptations. All resources preserved as blockchain records are secured and permanent. This can become very important if an institution disappears, or if a creator moves on to work elsewhere or retires.
Another positive dimension of using blockchain is that it helps overcome the fact that many quality open educational resources are hard to find on the web, and are wasted because of this. To date, there has been no efficient means of disseminating open educational resources that allows for maximum accessibility.
Blockchain can effectively support accessibility to open educational resources, housed in publicly available, distributed global knowledge databases. Applying blockchain in education has its own challenges.
These include the difficulty of changing established systems, legal questions on the ownership of the data, limitations in storage space and the need for privacy protection. Recent news on Bitcoin has focused on the total loss of access to the blockchain if a password cannot be retrieved. This human element of remembering passwords could prove a significant inhibitor of the use of blockchain in education.
In addition, like other online databases, blockchain is vulnerable to unexpected failures. The persistence of blockchain can also become a hindrance: If unwanted, fake, unscientific or illegal content is accidentally or maliciously added to a blockchain, it cannot be removed. There is also a lack of people skilled in implementing blockchain.
