Now that we live in the digital era, it is more than fair to say that we are positively immersed in and surrounded by magnificent feats of technological advancement. It seems that, all around us, digitalisation and technological innovation are proving themselves to be powerful entities in a world that is seemingly always becoming more and more digitally inclined. While for the most part, this is a positive thing, there is also the awareness that it comes with newfound cautions as well. Of course, the most obvious caution is privacy and security. While people have gotten quite good at protecting their privacy and security in the real world (for the most part, that is), we are still learning to navigate security in the digital landscape that we find ourselves exceedingly moving towards. With countless technological innovations surrounding us from all angles, it goes without saying that there is a legitimate need for greater privacy and security measures online.

One of the greatest technological security measures in recent history is blockchain. Digitalisation and technological advancement surround us from all angles, that much is certain. And while this is a great thing on many levels, it also brings with it an almost inevitable essence of concern that is etched into the reality we now find ourselves navigating. Thankfully, innovations like blockchain are literally designed to maximise privacy and security in the online landscape. The decentralised nature of blockchain makes it the perfect digital security measure, because of the framework that forms the basis of blockchain structures. Essentially, as new data (i.e. blocks) are added to the chain, the new information must be verified by all devices in the blockchain. If even one of the multiple devices is not able to verify the information for any reason, it is rejected from the entire blockchain. Each block is encrypted, making it especially private. This obviously effectively keeps the authenticity of the blockchain – and all the data within it – intact and as secure as it can be.

In the beginning, blockchain was very much a niche. It was designed to function and thrive as the foundational framework behind cryptocurrency giant Bitcoin. And while even today Bitcoin is still controversial (to say the least), blockchain has gone from strength to strength. In a world where there is more necessity for privacy and security online than ever, there is immense power in the capability and ongoing promise of the growth of blockchain. This is a technological innovation that, despite many hurdles coming its way, has continued to go from strength to strength, delighting and impressing time and again. It is an impressive growth, especially considering the controversial beginning that blockchain faced, being introduced to the world as the framework for an entirely new currency form. Now, as blockchain continues to become more and more popular all around the globe as the leading privacy and security framework for the online landscape, it appears that there is no end in sight for the continued growth of this remarkable technological advancement.

Blockchain is now being utilised as the leading online security measure for multiple areas in modern life. From the online hiring services that are used to hire commercial cleaners, to the most sensitive information at global empires, and everywhere in between, blockchain is becoming more and more popular as the leading digital privacy and security source around the world. Of course, this makes perfect sense, but alas it is encouraging and exciting to see the ongoing evolution and growth of blockchain – especially when some people believed that it would never become more than the niche respective framework that bolsters cryptocurrency Bitcoin. While not a technological innovation that has been without its challenges, blockchain has faced more than usual, and nonetheless has persevered to become the modern day digital success story that it is today. While the future of blockchain cannot be predetermined (can anything be definitively predetermined?), current projections and movements in blockchain suggest a healthy and exciting future for blockchain going forward.

The digital era is well and truly here, and with it has come wave after wave of innovations and transformations that make us not only more aware of the world around us, but that enhance the human experience. With all these innovations, of course, comes the almost inevitable privacy and security concerns. The more that people around the world invest in the online landscape that surrounds them, the more obvious it becomes there is a genuine necessity for privacy and security measures to protect people as they communicate and carry out activities online. Of all the technological innovations introduced in efforts to create more secure privacy standards in the online landscape, blockchain is arguably the most efficient of them all. The decentralised nature of blockchain ensures that it is practically impenetrable, meaning that it is virtually impossible for anyone to hack into it or otherwise disrupt the authenticity of online activity. It goes without saying that blockchain is today’s leading digital security measure, and it makes all the sense in the world as to why that is.
