With blockchain technology, you can imagine a world in which contracts are embedded in digital code, stored in transparent, shared databases, and protected from deletion, tampering, and revision. In this world, every agreement, every process, and every payment would have a digital record and signature that could be identified, validated, stored, and shared. Mediators like lawyers, brokers, and bankers may no longer be necessary. This is the immense potential of blockchain.
What is Blockchain, and How Does it Work?
Blockchain technology is a system that stores public transaction records, called blocks, in multiple databases, called chains, across a network connected through different devices known as peer-to-peer nodes. This storage is called a ‘digital ledger.’
The owner's digital signature, known as a Hash, authorizes every transaction in this ledger, authenticates it, and safeguards it from tampering. Hence, the information the digital ledger contains is highly secure.
For example, the digital ledger is similar to a spreadsheet shared across multiple computers in a network, where transaction records are stored based on actual purchases. The important part is that anyone can view the data, but no one can corrupt it. Digital ledgers also reference the data's attribution to the respective digital signature or hash, rather than to a specific individual, thereby not exposing their identity.
The blockchain is a new way of storing and transferring data, wherein, instead of holding the data in one place, the information is spread across thousands of nodes on a network, all locked together with the help of cryptography. Blockchain replaces centralized authority with decentralized computing and storage. It provides a new way of transacting with one another by bypassing traditional centralized systems like banks. The blockchain gives you a decentralized, immutable database or a trusted digital ledger of transactions. Using cryptography, anyone on the network can view and maintain secure exchanges. Before an exchange can be verified and recorded, this network, basically a string of computers, needs to approve.
For example, the Internet was created to move information quickly. That information needs to be stored somewhere; therefore, there are now numerous databases worldwide. Visualize them as a house that keeps information. It’s hard, but not impossible, to break into a house. Cybersecurity is an online lock protecting the house. Blockchain technology breaks the information into tiny parts and spreads it across many computers. It is the distributed part of the technology’s process. Instead of breaking into a single house, you now have to break into an entire city. If a hacker even manages to break into a block, his changes will be permanently and immediately visible.
Today, we are all dealing with internet security issues. We depend on the username and password method to protect our online assets and identity. We must create different usernames and passwords for different platforms, which are challenging to remember. Blockchain security relies on encryption technology. The basis for this is private and public keys. The public key is accessible by anyone, while the private key is secret, and only you can view it. You can share your public key when you want to prove ownership, and you don't have to show or share your private key. This way, you can prove that assets and identity belong to you by verifying the ownership of the public key with your matching private key.
Importance of Blockchain
The blockchain solution is essential to many industries and sectors, including commercial finance, banking, government, healthcare, education, etc. These sectors are what make our society function. Here are some reasons why Blockchain technology is important and popular:
Digital Freedom: One of our fundamental rights as human beings is freedom. Central organizations offer connectivity in economics and finance, but also take away the user’s freedom. For example, you hold your money in the bank, and if you want to withdraw the money via ATM, there is a daily limit. Even if you decide to withdraw money directly from the bank, you have a limited time (during Bank business hours and weekdays only) to access your money.
Using blockchain technology, you will control your digital freedom. You keep your own records, so you are your own bank and have more financial privacy. You can send and withdraw money quickly without anyone’s permission. You are the sole owner and are responsible for asset management.
Low Cost: Mostly, consumers pay a bank to verify a transaction, a notary to sign a document, or a minister to perform a marriage. Again, take the previous example where you’re sending money to another country. You will go to the bank or transfer the money via the payment transfer app. However, these options involve a third party that would process the transaction and simultaneously charge a transfer fee, an exchange rate, and other specific fees.
Blockchain technology can help avoid this scenario. Blockchain, as a decentralized technology, eliminates the need for third-party verification, so there is no need to pay intermediaries. Blockchain technology is much cheaper than other technologies and systems.
Privacy and Security: Today, each organization keeps a separate database where all users' information is stored, which presents a security risk. For example, hackers may be able to break into these systems and retrieve your login information, plus store it for use at a later date.
Blockchain does not store any information in a central database. By spreading that information across a network of computers, blockchain becomes more difficult to tamper with, rather than storing it in a single central location. Blockchain creates an unalterable record of transactions with end-to-end encryption, which shuts out fraud and unauthorized activity. Blockchains are open-source software, and no one controls or manipulates the network.
Decentralized: The decentralized network has no governing authority or a single person looking after the framework. The core idea here is to place your trust not in a single entity, such as a government, a bank, or a multinational company, but rather in the network.
For example, you can store anything, from cryptocurrencies and documents to contracts and other valuable digital assets. And with the help of blockchain, you’ll have direct control over them using your private key. So, the decentralized structure gives you authority and ownership back on your assets.
Time Reduction: Transactions placed through a central authority could be time-consuming. For example, if you want to make cross-border trades, the process takes around 24 to 48 hours to transfer the money. The transaction takes even more time if weekends or bank holidays are involved.
Blockchain mitigates such issues and cuts the processing time to a few minutes. The technology can potentially improve transaction speeds and eliminate many unnecessary intermediaries.
Rainfall and Blockchain Technology
Rainfall uses blockchain technology; when you allow Rainfall to access your data, we distribute and store the insights derived from your data securely and anonymously to ensure your data privacy. Also, our approach ensures your data never leaves your device.
Our edge-based AI algorithm and decentralized blockchain technology remove all human involvement in the verification process. The revenue generated from the insights derived from your data is automatically distributed back to you in your Rainfall wallet. This provides fewer errors and an accurate record of all transactions.
Rainfall uses blockchain technology for these reasons:
- To enable a completely decentralized platform and computing, Rainfall has no centralized control.
- To facilitate secure, private, yet auditable transactions.
- To store the insights derived from your everyday data in a distributed manner.
Using blockchain technology, Rainfall provides you the ability to decide what digital data you want to share. In a world where data is a precious commodity, technology protects the data that belongs to you while allowing you to choose what you want to do with it. With Rainfall, you will be in control of your digital freedom.
