Cryptocurrencies are digital financial assets that are made to act as a medium of exchange. They use the science of cryptography to secure transactions, make global currencies, get rid of government control and exchange rate problems, and control the creation of more units of the currency.
Cryptocurrencies were created as a disruptive financial technology (fintech) that would make global transactions easier, faster, and safer while putting control directly in the hands of the parties involved. This could also put an end to banks and services that move money.
What is the purpose behind Cryptocurrency?
Digital currencies claim to make it safe, fast, and unaffected by fees, exchange rates, or government rules to store, spend, and send "digital money."
But financial institutions, currencies, and transactions are not the only things cryptocurrency and the technology behind it are used for. Some of the first things that blockchain technology was made for were to secure data, protect identities, create a decentralized economy, and store personal data in a safe way.
Even though there are many ways to use the blockchain technology that powers cryptocurrency exchange development services, blockchain identity use cases are the ones that are getting the most attention from technology fans around the world.
Blockchain technology can now be used to verify digital identities, passports, e-residency, birth certificates, marriage certificates, and other forms of ID.
Is it safe to use blockchain technology?
A blockchain is a list of blocks that store information in hash functions and timestamps so that the information can't be changed or hacked. Since data can't be erased, it's very hard to change it. This keeps data safe and gets rid of the centralized points that cyber criminals often try to attack.
Also, private analysts say that the Pentagon thinks Blockchain Technology could be used as a Cybersecurity shield. In an article from The Washington Times, analysts say that using blockchain, the technology behind bitcoin, could dramatically improve security across the U.S. military, preventing mega hacks, tampering, and cyber-hijackings of vehicles, aircraft, or satellites.
The key to blockchain's security, according to Dan Boylan of The Washington Times, is that any changes made to the database are immediately sent to all users. This makes a secure, permanent record. Since all users have copies of the data, even if some users are hacked, the database as a whole is still safe.
Because it can't be changed and isn't controlled by one person or group, blockchain is becoming more and more popular outside of its original purpose of supporting bitcoin digital transactions. For example, many cutting-edge finance companies have used blockchain to speed up processes, cut costs, and keep security at the same level.
Even though blockchain has some advantages over other systems, there are still some problems that need to be solved when it comes to compliance, regulations, and enforcement.
For example, regulatory issues like KYC (Know Your Customer) and AML (Anti-Money Laundering) laws need to be clear about where they apply and how to follow them. But a gradual rise in demand and acceptance by businesses would help solve these problems faster than expected.
How Blockchain Technology Can Help with Security
In talks about blockchain technology, people have said that it can be used to make big changes in the security industry as a whole.
People often say that the technology is useful not only for driving the exchange of digital currencies but also for making existing security solutions stronger and addressing security concerns around the world.
Blockchain technology hopes to solve problems like double spending, data security, cross-border transactions, chargebacks, fraud, and fake currency. Using blockchain cuts down on the costs of online transactions while at the same time making them more legitimate and safe.
Some of the ways that blockchain technology could be used to improve global security are:
Protecting sensitive records and verifying a user's identity, especially in the banking industry:
With the help of blockchain technology, data manipulation can be found. This lets banks do more than just use asymmetric encryption and store public keys. When blockchain is used, users and devices can be verified without needing a password. Because the network is not centralized, it is easier for different parties to agree on what needs to be checked using SSL certificates based on the blockchain. Because the network that checks the integrity of transactions and account balances is distributed and decentralized, it is mathematically impossible for an attack to work.

Improving the structural security of IoT devices
In these kinds of networks, devices can recognise and talk to each other without the need for a third-party authority. With two-factor authentication, this gives the network structure a level of security that has never been seen before and makes it impossible to fake digital security certificates.
Internal communication
It is often vulnerable to data leaks and cyber espionage, so they need to be kept safe. End-to-end encryption doesn't protect the metadata, which means sensitive information could get out. In systems that use blockchain, the metadata used for communication is spread out across the distributed ledger and can't be gathered in one place.
This makes passwords obsolete
With REMME's blockchain, users and devices can be verified without the need for a password. This takes the human out of the authentication process, which makes it less likely that it could be used to launch an attack.
Privacy and security of digital chats
Messenger services make up a big part of how people use the Internet today, especially since apps like Facebook Messenger, Viber, WeChat, Alipay, and WhatsApp are already used to pay for things and interact with users through chatbots. With more than a billion people using these apps, there is a risk of social engineering, hacking, and other security flaws. Obsidian uses a decentralized network called blockchain, which can't be controlled or censored by a single source. Also, meta-data about communications is spread out across the distributed ledger, making it harder for digital fingerprints to be used for surveillance. Users don't have to link to their email addresses or phone numbers, which makes them more private.
Blockchain technology has set the stage for a future of smart contracts by getting rid of human mistakes, making it easier for computers to spot fraud, and putting up a fence around data, identities, and transactions that can't be broken through.
Smart contracts, which are also called "digital contracts," let you trade money, property, shares, or anything else of value in a clear, conflict-free way without using a middleman.
Self-executing contracts are agreements between a buyer and a seller where the terms of the deal are written directly into lines of code. A distributed, decentralized blockchain network holds the code and the agreements it makes.
Smart contracts can be used in fields as different as health care (digital identity), politics (digital voting), cars, real estate, management (smart contracts), and the law (decentralized notaries).
Blockchain technology has more uses than just in business and finance. Coindesk has made a list of the ways security issues are used in other fields.
Blockchain has become one of the most innovative technologies, and it has solved many of the security problems that have been plaguing financial transactions.
As more ways to use the technology in the real world are found, blockchains are becoming strong candidates for solving a wide range of cybersecurity problems and giving global institutions end-to-end security.
