Blockchain a Technology Good or Bad or 0?

Spread the love

Blockchain is a constantly growing ledger that keeps a permanent record of all the transactions that have taken place in a securechronological, and immutable way.

This Technology is a distributed database that maintains a continuously growing list of records called blocks. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin and other cryptocurrencies are based on this technology.

Authenticity and Genuineness can be provided by Blockchain. Let’s start with some questions. If you buy any brand of watch or sunglasses, how can you say it’s genuine? How can you say a Painting or sculpture is made by an artist? Or is it a stone? Being able to have accurate information, provenance and history of any item or value is essential. But the world is dealing with malware. We all are dealing with hackers.  We are dealing with all sorts of goods put into supply chains all over the world. 

It is becoming increasingly more difficult to prove the authenticity and guarantee the integrity of any item or value you are buying. There is an answer. The Technology is called Blockchain. Because Blockchain can provide you with a single source of truth. That’s permanent, verifiable, and unchangeable.

Blockchain System

Blockchain Explained

It is a sort of shared database that varies from traditional databases in the way it is stored: data is stored in blocks, which are then connected together using cryptography.

As new information is received, it is entered into a new block. Once the block has been filled with data, it is chained onto the preceding block, forming a chronological chain of data.

It is a distributed, unchangeable database that makes recording transactions and managing assets in a corporate network more easier. A tangible asset (a home, vehicle, cash, or land) can be intangible (intellectual property, patents, copyrights, branding). It network can track and sell virtually anything of value, lowering risk and slashing costs for all parties involved.

Blockchain Wallet

It is a digital wallet that stores and manages Bitcoin, Ether, and other cryptocurrencies. The wallet service supplied by Blockchain, a software business created by Peter Smith and Nicolas Cary, is also known as Blockchain Wallet. A blockchain wallet lets users to send and receive cryptocurrencies, as well as convert them back into their home currency.

Blockchain Technology

It is a network of peer-to-peer nodes that keeps transactional records, also known as blocks, of the public in various databases, also known as the “chain.” This type of storage is sometimes referred to as a ‘digital ledger.’

Use Cases of This Technology

Blockchain for Healthcare.

In the healthcare sector, a Blockchain network is used to store and share patient data across hospitals, diagnostic laboratories, pharmacies, and clinicians.

It is an emerging technology being applied for creating innovative solutions in various sectors, including healthcare. A Blockchain network is used in the healthcare system to preserve and exchange patient data through hospitals, diagnostic laboratories, pharmacy firms, and physicians. Blockchain applications can accurately identify severe mistakes and even dangerous ones in the medical field. Thus, it can improve the performance, security, and transparency of sharing medical data in the health care system. This technology is helpful to medical institutions to gain insight and enhance the analysis of medical records.

Blockchain for Supply Chains.

Blockchain for supply chain solutions help supply chain leaders use data to handle the disruptions of today and build resiliency for the future.

Many supply chains face challenges that have significant implications in terms of cost, speed, and (product) quality. In our experience, the most critical supply chain challenges—despite years of efforts and often significant investments—are lack of transparency due to inconsistent or even unavailable data, high proportion of manual (paper) work, lack of interoperability, and limited information on the product’s lifecycle or transport history. In many cases, blockchain applications can counter these inefficiencies and add new value.

Blockchain for Digital IDs.

Blockchain can empower users to have greater control over their own identity. Organizations can use the information only with customers’ consent and no central entity would be able to compromise a consumer’s identity.

Blockchain for Data Sharing.

We propose a new platform for user modelling with blockchains that allows users to share data without losing control and ownership of it and applied it to the domain of travel booking. As per Our www.frontiersin.org, their new platform provides solution to three important problems: ensuring privacy and user control, and incentives for sharing. It tracks who shared what, with whom, when, by what means and for what purposes in a verifiable fashion.

Blockchain for Copyright and Royalties Protection.

With the recent development in network technology over a few years, digital works can be easily published online. One of the main issues in the field of digital technology is the infringement of digital works, which can seriously damage the data owners’ rights and affects the enthusiasm of the owners to create original work.

Thus, more attention is required for the protection of digital copyright as it has a great impact on the development of society. Many digital copyright protection techniques were developed in the past, but still, there are many loopholes in the protection systems to be covered.

The protection means are still relatively weak, timeliness is poor, infringement is frequent, a right determination is cumbersome, and the results are not ideal. Source: https://peerj.com

Blockchain for Internet of Things Network Management.

The Internet of Things (IoT) connects people, places, and products, and in so doing, it offers opportunities for value creation and capture. Sophisticated chips, sensors, and actuators are embedded into physical items, each transmitting data to the IoT network.

The analytics capabilities of the IoT use this data to convert insights into action, impacting business processes and leading to new ways of working. However, there are still a number of technical and security concerns that remain unaddressed.

Security is a major concern with IoT that has hindered its large-scale deployment. IoT devices often suffer with security vulnerabilities that make them an easy target for Distributed Denial of Service (DDoS) attacks. In DDoS attacks, multiple compromised computer systems bombard a target such as a central server with a huge volume of simultaneous data requests, thereby causing a denial of service for users of the targeted system.

A number of DDoS attacks in recent years have caused disruption for organisations and individuals. Unsecured IoT devices provide an easy target for cyber-criminals to exploit the weak security protection to hack them into launching DDoS attacks.

Another issue with current IoT networks is that of scalability. As the number of devices connected through an IoT network grows, current centralised systems to authenticate, authorise and connect different nodes in a network will turn into a bottleneck. This would necessitate huge investments into servers that can handle the large amount of information exchange, and the entire network can go down if the server becomes unavailable.

According to Gartner’s Forecast, Internet of Things endpoints are expected to grow at a compound annual growth rate of 32 per cent from 2016 through 2021, reaching an installed base of 25.1 billion units. With IoT devices expected to be such an integral part of our daily lives in the coming years, it is imperative that organisations invest in addressing the above security and scalability challenges.

Another breakthrough technology, blockchain or distributed ledger technology (DLT), has the potential to help address some of the IoT security and scalability challenges. Blockchain is an ‘information game changer’ due to its unique capabilities and benefits.

At its core, a blockchain system consists of a distributed digital ledger, shared between participants in the system, that resides on the Internet: transactions or events are validated and recorded in the ledger and cannot subsequently be amended or removed.

It provides a way for information to be recorded and shared by a community of users. Within this community, selected members maintain their copy of the ledger and must validate any new transactions collectively through a consensus process before they are accepted on to the ledger. 

Blockchain for Internet of Things

Blockchain can help alleviate the security and scalability concerns associated with IoT in the following ways:

  • The distributed ledger in a blockchain system is tamper-proof and this removes the need for trust among the involved parties. No single organisation has control over the vast amount of data generated by IoT devices.

  • Using blockchain to store IoT data would add another layer of security that hackers would need to bypass in order to get access to the network. Blockchain provides a much more robust level of encryption that makes it virtually impossible to overwrite existing data records.

  • Blockchain provides transparency, byallowing anyone who is authorised to access the network to track the transactions that happened in the past. This can provide a reliable way to identify a specific source of any data leakages and take quick remedial action.

  • Blockchain can enable fast processing of transactions and coordination among billions of connected devices. As the number of interconnected devices grows, the distributed ledger technology provides a viable solution to support the processing of the large number of transactions.

  • By providing a way to enable trust among the stakeholders, blockchain can allow IoT companies to reduce their costs by eliminating the processing overheads related to IoT gateways (for e.g. traditional protocol, hardware, or communication overhead costs).
