We live in a world that is positively surrounded and immersed in technological advancement and certain digitalisation. We are more comfortable, more connected than ever before, and somehow that innate sense of complete connection is something that makes us more vulnerable than it does secure. This reality of course has a lot to do with the fact that, in allowing and encouraging further technological innovation, we are becoming more involved with it and dedicated to its reaches. The result of this is that we subconsciously pull away from the world around us. In doing this, we invest more time and input more information into the online stratosphere, which makes us more visible and vulnerable online. The nature of the internet is that once something is out there, it stays out there. This goes for both written and visual content, of all kinds…bank details, personal information, you name it. Thankfully, in this rising age of vulnerability online, there are various methods and systems that are centred around computer security and privacy (think VPN security, password protection, two-factor authentication, to name a few).
One of them started out as primarily a function that served digital financial transactions and history, but has expanded in recent times, now effectively serving multiple functions (a digital security multitool, if you will). That system is called blockchain. Blockchain is essentially a network that records and maintains transactions and interactions across multiple devices that are linked to one another via a peer-to-peer network (most commonly cryptocurrency transactions and records, for example). The decentralised nature of blockchain means that its creation from a network of devices makes it safer against hackers and other cyber attacks. This is because there is no one server for cybercriminals and malware to latch onto. Initially charged with protecting financial transactions online, blockchain has grown so much in recent years. There is something to be said about the incredible (and frightening) power of the surge in tech advances over recent years, but at least there are protective measures being developed and expanded at the same time.
And blockchain is fast becoming a weapon in more than solely the financial sector online. There is significant growth of blockchain capability across many industries, and it is being regarded highly as the next best thing in device security and privacy. Any new information must be verified by multiple computers (the devices in the blockchain network). Because of this, it is practically impossible to input disingenuous information to the blockchain. If most of the computers do not verify a new input of information (this is done through its history and its transaction signatures), then the information in question is not added. The potential for blockchain technology is only just now beginning to unfold at a rapidly advancing pace. Before, blockchain was thought to be of use solely to financial situations, but it is now obvious that blockchain is something that can and will have substantial positive impact on the security and privacy of devices across multiple channels and industries. Increased optimisation, digital security and privacy revitalisation, and the revolution of varying industries.
Blockchain is without a doubt one of the pillars of computer security and privacy in this modern age. The impact of computer security and privacy measures like blockchain cannot be overstated, and there is something to be said for investing in the progression of these types of security and privacy measures. The digital stratosphere is a place that will more than likely always continue to expand and evolve, and the flip side of the coin is that the threats and risks to online security and privacy will also be constantly evolving. Having adequate and reliable protective measures in place is both smart and inevitable. The refusal to do so could definitely result in considerable risks and an increase in hacker activity and other cyberattacks. We are already so vulnerable in our increased use of the worldwide web and all its reaches. The very least we could do to protect ourselves is go out of our way to ensure that we instil device security and privacy measures – like blockchain – from the beginning.
Blockchain first started out as a security and privacy function that served digital financial transactions and histories. Through the rise of technological advancement and digitalisation, we have increasingly relied on the internet for communication, information, knowledge, and personal use and access. Making us so connected would, in an ideal world, make us more secure. But the nature of the internet is that by putting more of our information out there and entrusting more of our data to the digital stratosphere, we are making ourselves vulnerable to hackers and other cyberattacks. Luckily, there are multiple online security and privacy reaches available now. Blockchain is one of them. Serving as a reliable, sturdy prevention against hackers and the like, blockchain aims to provide immense benefits in faster processes, financial efficiencies, and digital trust. When we are increasingly investing in digital presence more and more, having effective, capable, fast, and reliable device security and privacy systems is so fundamentally important.
