Blockchain technology started to gain people’s attention back in 2009. Since then, it has made exponential advancements, and more and more sectors have begun incorporating blockchain technology into their systems and processes. The current applications of blockchain technology are vast, and it is estimated that the future of blockchain will be even more widespread.
The broad acceptance of blockchain technology over traditional database systems is largely attributed to its distinguishing features. In a comparison of blockchain versus traditional databases, it becomes evident that blockchain stands out with features like immutability, better transparency, higher security, and decentralization.
As blockchain technology becomes more prevalent and advancements are made, blockchain is estimated to replace traditional database mechanisms. The enterprise blockchain market is expected to reach 246$ billion by 2030, up from 4.9$ billion in 2021.
Following is a brief account of the future of blockchain in various fields and sectors.
In a blockchain network, the data is encrypted by cryptography. Each information block is linked to other blocks with a unique hash value, and the record is visible and accessible to everyone in the network. The information can be verified by anyone at any time.
Blockchain-based cyber security systems would make it almost impossible for hackers to attack or steal information.
Data stored on centralized servers are more prone to hacking, corruption, and technical and human errors resulting in data loss. As blockchain is decentralized, the data is not in the hands of a particular authority, organization, or server. Rather it is disseminated among a network of nodes. Each node has its own copy of the record. So, if a blockchain-based cybersecurity system loses data from one of its nodes, extracting data using other nodes wouldn’t be difficult.
Blockchain-powered cybersecurity systems would be tamper-proof as any change in the record requires consensus from the maximum number of participants.
In short, blockchain technology has the power to innovate cybersecurity and provide better and safer solutions to companies and individuals.
Internet of Things
The Internet of Things faces many security, tracking, and traceability challenges. Blockchain technology has the potential to provide solutions to the current problems in the field.
IoT integrated with blockchain can allow companies to track the position, arrival time, and shipment of products during freight movement. This data is immutable, so organizations can trust freight forwarders and shipping companies.
IoT data stored on a blockchain will allow manufacturing companies to keep track of ownership of a product throughout its life. It also makes sharing this data with shippers, consumers, or regulatory authorities for administrational or legal operations easy.
IoT devices like elevators and fire alarms monitor and detect critical security and safety conditions. If integrated with blockchain, the data recorded by these devices can be stored on a blockchain shared with third-party repair service providers for timely management of any possible mishap.
Another problem faced by current IoT systems is the security issues like cyberattacks. In October 2016, the US internet systems were taken down by cyberattacks from malicious software that infected traffic from IoT devices like webcams, video recorders, baby monitors, etc.
In short, in the future of blockchain, we can expect a profound positive impact on the safety and security aspects of IoT systems.
Finance and Banking
Blockchain systems are the underlying technology of cryptocurrencies like Bitcoin, Ethereum, etc. The current trend of global inflation and the increasing costs of money transfers between financial intermediaries imply that cryptocurrencies are the future of finance.
Transactions in cryptocurrencies are decentralized, transparent, and secure. As no middleman or regulatory authority is involved, the exchange is cost-effective and speedy, unlike traditional transactions that take some time to be authorized and validated.
Healthcare providers obtain and store a huge amount of personal data from patients. Such data needs to be stored securely to maintain patients’ privacy. Traditional organizations store data in a centralized database, making it prone to attack and steal.
Blockchain technology can empower healthcare organizations which decentralized record-keeping systems that will be immune to modifying, deleting, or tampering. This allowed the sharing of data strictly between patients and authorized doctors only.
Blockchain can track and control drugs and their movement from pharmaceutical companies to patients(consumers). The unauthorized supply of drugs and counterfeit vaccines can also be detected and prevented.
Blockchain systems can also automate medical examinations, improve treatment transactions, etc.
Governments can also use blockchain technology to automate and streamline various operations. Voting can be made more transparent, efficient, and secure by using blockchain technology.
Blockchain will empower governments to keep identity records and manage sensitive data more securely, protect voter identities, prevent fraud and forgery, and support remote voting.
Governments relying on blockchain could eliminate many intermediaries, thus significantly reducing the chances of corruption.
A blockchain-based system would provide faster auditable reconciliation. This can help reduce redundancy and maintain data identity.
So, in the future of blockchain, we anticipate a transformation in the way governments operate.
Implementing blockchain technology enables safer, faster, and more reliable communications. Implementing blockchain can allow industries to make digital or automated communications based on prebuilt algorithms.
People using messaging platforms have concerns about the privacy and security of their information, like chats, etc., whether the companies sell their data, etc. Blockchain-powered messaging would decentralize data instead of storing it in a central server, ensuring privacy and data safety.
Donations and Charity
People who donate to charities online often have reservations about whether their money reaches the needy. Blockchain-based charity can alleviate their concerns by enabling everyone to track every cent throughout its journey from the donors to the recipients.
Blockchain databases can act as secure, immutable, and evident ledgers making it impossible for anyone to corrupt the record.
World Economy and Blockchain
Currently, international trade is inefficient. It slows down commerce and discourages trade between nations. The world of international trade is rife with fraudulent activities, counterfeiting, and political interference.
As blockchain becomes more and more prevalent in global trade, using cryptocurrencies would alleviate many of these problems. By shifting payments, paperwork, and regulations, to a single unified blockchain-based system, much of the scam and inefficiency can be eliminated.
The advancement of blockchain would also allow many other business operations like smart contracts, automated tracking, policy enforcement, etc.
In conclusion, blockchain technology has journeyed far since its inception, becoming an invaluable and indispensable tool for many industries. With its remarkable features like immutability, transparency, and decentralization, it has the potential to revolutionize many sectors.
In the future of blockchain, its endless applications – from cybersecurity to finance, governments, and charity – will continue to innovate and shape our world.
