Today, a huge chunk of employees across the globe have returned into a physical office environment and several others are scheduled to resume working-from-office after remotely working for a long time. But, the fear of getting infected with the Covid19 virus persists.

So, how could organizations maintain safety protocols at their workspaces? Well, the two most effective mechanisms that are being incorporated by enterprises to ensure employee safety are: contact tracing and maintaining digital health wallets for employees. However, there are security risks involved in both these processes and so employees may be reluctant to adopt these processes.

This post explores how Blockchain application development improves the effectiveness and enhances the safety quotient of the aforementioned processes.

Before we delve deeper, check out the unique attributes and functioning of Blockchain technology!

The participants, who are a part of the blockchain, are connected through a distributed network. “Nodes” (computers) are present for operating this network. The nodes run programs for imposing the rules laid down by the business enterprise that owns the blockchain. The nodes also maintain a copy of the ledger and updates data independently, whenever a new transaction takes place.

Blockchain is a decentralized ledger, based on peer-to-peer technology, in which the information is distributed across the network instead of being stored by one single entity. As such, no entity can control a majority of the nodes or dictate terms. Thus, unlike the traditional approach, this approach eliminates the need for a centralized authority for controlling the network. Instead, multiple participants are authorized for managing the network – a “consensus mechanism” is employed for approving and checking transactions. Decentralization, increases reliability as the users no longer have to trust a third-party authority and also minimizes the risk of systematic failures considerably. Hence, Blockchain solutions are more transparent, secure, performant, and irreversible.

This feature uses pseudonyms to record the participants’ details and thus ensures the security of all recorded data. The participants are entitled to control their personal details and share them only with authorized entities whenever needed.

With this functionality, items of value or physical or non-physical elements are converted into “tokens”. Blockchain identifies these “tokens” as “currency” within the system and these can be traded as well. Data and even a participant’s identity can be represented as the value that can be converted to tokens and then traded.

This aspect of Blockchain imparts a layer of accountability that is a crucial prerequisite for several enterprises. All transactions can be searched for as well as traced in open Blockchain. And, to protect data privacy, granular access is provided to certain authorized users and at the same time, the data is protected from unauthorized access.

This ground-breaking property of Blockchain rules out any third-party interference to the continuously growing chained data. Blocks are used for storing data introduced into Blockchain and these blocks are connected as well as secured by cryptography. Each block is given a unique identification number employing a cryptographic algorithm and is called the cryptographic hash function. During a transaction, blocks are time-stamped, sequentially added to the ledger, and cryptographically signed. Each block contains its own hash, transaction-related data, a timestamp, and the cryptographic hash of the previous data. As such, data once entered into the Blockchain network, cannot be tampered with.

When somebody joins the Blockchain network, an entire copy of the Blockchain is received and the nodes verify whether every aspect is in order. This new block is then sent to all participants of the network and the block is verified by each node for ensuring that no tampering has taken place. Once successfully verified, the block is added by each node into their Blockchain and the transaction is completed.

For ensuring the authenticity of this new block, the nodes use a particular consensus mechanism. All the nodes present within the network create a consensus by agreeing on which of the blocks are valid and which of them are invalid. Any block within the network that has been tampered with will be rejected by the other nodes of the network.

So for tampering with a Blockchain system successfully, one must manipulate every block contained within the chain and then gain control over more than half of the P2P network, which is not possible by any means.

Today, contact tracing and maintaining digital health wallets for employees has become an essential prerequisite to ensure safety protocols at workplaces. And, employing Blockchain app development for architecting such solutions is necessary. Let’s explore!

Contact tracing is a mechanism that is implemented for limiting the spread of communicable diseases or disease-causing viruses. This process involves the following steps:

Individuals infected with a communicable disease are identified and asked about their routine activities and locations visited in the recent past. This is done to identify other individuals like family members, colleagues, friends, medical practitioners/staff, etc. who were within close vicinity of the patient.

Once identified, a list of all persons who have come in close contact with the patient during the past couple of days is prepared. These contacts are then tracked down and notified about the situation. They are also provided guidance on the timely measures to be adopted and the practices to follow if they develop any symptoms of the communicable disease and are advised to stay in isolation if needed.

The health symptoms of these contacts are closely monitored by conducting regular/periodic follow-ups and tests to limit the spread of the disease.

Contact tracing was implemented in the past to control the spread of various communicable diseases. Also, for tackling Covid19 the traditional approach was implemented in some countries. But, the traditional approach comes with certain limitations. The lists of identified contacts who are likely to contract the infectious disease are maintained in paper files and the contacts are notified as well as advised via phone calls or emails. So, the entire process becomes not only time-consuming but also error-prone. To sum up, the paper-based system is unorganized, incomplete, less effective owing to data redundancy, alterable, insecure, and less accurate.

In modern times, digital contact tracing, with the use of contact tracing apps via smartphones is trending. This method guarantees prompt as well as convenient contact tracking and is being implemented for tracing down Covid19 patients and their contacts in several regions. But, this approach too, comes with its share of downsides, the key challenges being issues concerning transparency and risks to the security and privacy of personal/medical data, if the apps are not bound by strict privacy rules like GDPR.

For example, the Covid19 patients need to upload their personal data to the centralized server so that the concerned authorities can download it and use it in contract-tracing maps. But, during this process, the users’ data becomes vulnerable to risks like trajectory attacks and reconstruction of information. For this reason, many users are reluctant to share personal health information and if the participation rates are low, the apps become virtually useless.

So, the employers whose employees need to share personal data using a contact tracing application must comply with the laws mandated by the State, Federation, and Region, depending on the kind of data that is being collected. Some regions in the U.S like California have enforced privacy laws for protecting the geolocation data of individuals by providing the option of opting out or deleting obligations. But such laws do not exist in other areas of the country.

Despite its challenges, there is no other better option than using digital contact tracing app solutions for contact tracing, and integrating Blockchain technology for building such applications is the one-stop solution. Blockchain-powered contact tracing apps can successfully resolve all challenges and also enhance the efficiency, accuracy, and speed of this system. In such solutions, a symmetric key cryptographic mechanism is employed to avoid misuse of data and guarantee the privacy of users’ data. And, digital contact tracing is decentralized, thereby keeping users’ data private and secured and ruling out any chances of trajectory attacks.

While the contact tracing process is needed for isolating the Covid19-affected individuals, there also needs to be an effective means of verifying that all employees entering the workplace have tested negative. For fulfilling this requirement, employees need to share their test results and immunization records digitally with third parties like the employer, TSA agents, transportation personnel, etc.

Here again, data security is essential and hence, a digital health wallet based on Blockchain is needed so that the users’ sensitive/personal data is protected from the risks of getting exposed.

Persons who wish to get tested for Covi19 need to share their Blockchain-powered digital ID with their healthcare service provider. Once the test is conducted, the medical provider will upload the test results and link them to the patients’ digital credentials with cryptographic evidence, so that its authenticity could be easily verified by any third party. Thereafter, the test result is directly issued into the health wallet of patients.

On reaching the workplace, an employee is required to scan his/her QR code with a smartphone/computer application for verification. This app would then extract the information contained within the credential and check the evidence prior to displaying the test result.

Blockchain entirely decouples the users’ Covid19 status from their personal information, ruling out any possibility of data reconstruction. Moreover, the data can be moved off the chain into a private database so that the owner can directly control his/her data and delete obsolete data. Thus, the decentralized platform created by Blockchain ensures the privacy of users’ data. However, for making this model work effectively, the Covid19 test results and immunization records provided by medical bodies need to be wallet-ready.

With Blockchain-empowered systems in place, coupled up with other common safety measures like social distancing amongst colleagues, daily screening of employees, etc. employers would be able to create a safer workplace.

Blockchain technology came into being as support for cryptocurrencies. Interestingly, this technology has evolved into a game-changing solution that has reshaped the functioning of diverse industrial domains and the fashion industry is no exception.

The Blockchain-infused approach was introduced into the fashion industry at the Shanghai Fashion Week, held in 2016. Here, the renowned apparel brand Babyghost, partnered with technology providers to create a Blockchain Apparel Technology that allowed all the stakeholders of the supply chain including customers, to validate the authenticity of the clothing manufactured by the brand. Small-sized chips and accessories were embedded within the clothing items so that one can scan and determine whether a specific garment was authentic.

Today, Blockchain has emerged as an effective solution that addresses myriad challenges encountered by the fashion industry and ushers in the much-needed transparency. Let’s explore its role in transforming the fashion industry!

Blockchain, a P2P (peer-to-peer) decentralized distributed ledger technology, guarantees that the records that are stored within cannot be destroyed or forged. The key objectives are to offer immutability, transparency, security of data, and evidence whether a specific data is safe and has not been altered. And, despite being known for its pivotal role in the origin of digital currencies, this technology is equally effective for non-crypto currency uses as well.

Blockchain comprises a group of blocks that carry information. These blocks possess information concerning transactions like purchasing behavior, consumer profiles, the time and date of operations, etc. Each block consists of a unique set of data identifiable by a “HASH” code algorithm. Since it stores data sequentially, it can be considered as a database shared across a private/public network. A copy of this shared database is present with each authorized user. This arrangement prevents any malicious users from altering the database’s content. As this database/ledger is “append-only”, one can only add data but not carry out any modifications of the existing data. Therefore, the P2P network provided does not need the involvement of any regulating authority or intermediary. The transaction records stored on a Blockchain enable identifying the owner of a value item and via the ownership, subsequent transactions are transferred, creating a chain of ownerships/authenticity.

Check out how Blockchain resolves the numerous roadblocks encountered by the Fashion industry!

Currently, most of the supply chains of the fashion industry lack transparency. This is because the supply chain for any fashion-related product involves several developmental stages that take place across a couple of countries around the globe. Therefore, fashion brands find it challenging to monitor the quality of raw materials that are used to manufacture their products. This roadblock can be effectively resolved by employing Blockchain technology. Blockchain’s NFC (Near-Field Communication) tags enable companies to track the entire product lifecycle and record the products’ journey globally.

As such, retailers are able to track the manufacturing process of apparel right from the consumption of raw materials to the creation of the end product which brings in complete transparency in the supply chain. Thanks to the transparency tracking methodologies, producers get useful insights into their value chain and can ensure the proper execution of processes such as handing off goods to third parties and labeling the end product.

The Blockchain-empowered solutions are known for their distinct capability of creating a physical-digital link between the goods and their digital identities on a Blockchain. Usually, a serial number or a cryptographic seal plays the role of the physical identifier and links back to the “digital twin” of an individual product. This way, each time a product changes custody, the Blockchain records that change. For this reason, retailers can effortlessly identify counterfeit goods that miss the physical digital link as well as any attempt to divert goods in between. Moreover, the chain of custody on the Blockchain displays a record of the last party that has gained the products’ custodianship. As a result, it becomes obvious where the authentic product was diverted out and the counterfeit product was slipped in. This helps manufacturers protect their brands against counterfeiting.

The afore-mentioned process enables determining the authenticity and genuineness of a product for providing a digital authenticity certificate to every new product. For instance, Vacheron Constantin uses a Blockchain-backed validation mechanism for issuing a digital identification certificate to every new watch. Furthermore, each time a watch is serviced or transferred; this mechanism stores the records of the proceedings on a public ledger.

Blockchain integration enables brands to trace the weak links within their business operations. Hence, it’s easy to identify a production department that does not adhere to the defined quality standards or a supplier who provides defective materials. This enhances the efficiency of the manufacturing process and improves the overall quality of the end products.

The Blockchain ecosystem facilitates seamless tracking of royalty payments. This is because it enables the designers to create unalterable evidence of the design created. It can also be utilized for building and tracking trademarks, license designs, royalty programs, and the sales generated through such design creations.

Digital clothing has garnered popularity in recent times as designers are providing consumers the option of purchasing digital apparel and the ability to digitally fit in it. Blockchain apparel technology enables transferring the ownership of digital clothing items. It also rules out the possibility of any issue concerning the stealing of product designs, thereby creating uniqueness and desirability.

Blockchain technology facilitates the creation of solid proofs of usage for trademarks. These trademarks save time and expenses for companies who have to undergo the hassles of renewing as well as securing a trademark when invalidity actions or disputes occur.

The Blockchain environment promises an effective supply chain, improves data management, and minimizes the risks of counterfeiting. It seamlessly integrates surfaces for reconciling data through operational as well as service lines. These advantages help in optimizing operational costs.

If your brand is facing challenges in proving your worker welfare standards to the industry or needs to authenticate the origin of raw materials/goods in the supply chain; it’s high time you should hire experienced Blockchain app development Company.

The first step is holding a discussion with Blockchain app developers on building a solution that would collect information from the right set of people. Next, instruct the developers to design a structure of information that will allow you to know the details of the raw materials/fabric/chemicals used. Once your objective is clear, go ahead and select the apt Blockchain platform that will suit your requirement as there are many of them with distinct functionalities. Thereafter, you need to begin with creating the frontend and UI of the application. Also, make sure that your Blockchain-powered app can be effortlessly used by all your stakeholders.
