Think of a record, maybe a book record but in a digitised form. A record that isn't under the authority of anyone, it belongs to everyone, is accessible to anyone. A record where people can record their transactions in the form of blocks. These blocks represent the transaction files, and are permanent. Think of it, with each new block connected to the previous one using a cryptographic hash function. You can think of this hash function as an equation used to verify data; which means that not only is this record accessible and transparent, it is also non editable and secure. This record is the Blockchain.


As a decentralized, transparent and non-editable ledger, the Blockchain brings a revolutionary approach to data security; and in this week's post we'll be exploring these possibilities. Welcome to another session of our weekly Techsafe security awareness blog.


Blockchain security in action.

Blockchain technology holds a great promise in enhancing data security in various sectors. Apart from it's most common use in cryptocurrency and web3, Blockchain technology can be used to track fraud in the financial sector, it can be used to securely store and share sensitive patient data among healthcare professionals in the healthcare sector, and it can also be used to track products throughout the supply chain to ensure products haven't been tampered with in transit.


The uses and application of the Blockchain are far more than the above listed, but in its most common form of web3 and cryptocurrency application, it should be noted that as a web3 user with a Blockchain wallet, you should have additional basic security practices to ensure the assets stored in your Blockchain wallet remains secure. Regardless of the sort of Blockchain wallet- Hot or cold, it is advised that you secure your wallet with passwords, and ensure not to share your seed phrase if generated. Wallets on cryptocurrency exchanges should be extra secured by two factor authentication as well, and of course one should be careful of the links and websites we grant access to on our wallets. These and a lot more constitute basic security practices on your Blockchain wallet as we wouldn't want scammers to gain access to your wallet and transfer your assets out.


This brings us to the end of today's article. Blockchain technology application is wide and broad and its adoption should be advocated for, and just like in the case of our quantum computing discussion, what we've touch is just the surface of the possibilities the Blockchain can bring; and until next time, remain digitally safe!

  Online security is vital in today's digital world, and a strong password is the key to protecting your personal information and digital assets. Unfortunately, many people still use weak passwords, which can leave them vulnerable to cyber-attacks and data breaches. But it's not too late to upgrade your security! Here are some tips to help you create strong passwords and protect your digital assets.   Firstly, let's define what makes a password strong; A strong password should be complex, unique, and difficult to guess. It should contain a mix of upper and lowercase letters, numbers, and symbols, and should not contain easily guessed information like your name, birthdate, or favorite sports team. If you find it challenging to come up with complex passwords for all your accounts, you should consider using a password manager. These are handy tools that can help generate strong, unique passwords and store them securely for you, while saving you from the headache of trying to r...

Quantum computing: potential impacts of quantum computing on cybersecurity.

I remember asking my friend about the term ‘quantum computing’. For me at the time, it was just a new word, a new world, maybe too far from the one I existed in, so I wanted to understand it. The closest I had come to that was when my dad talked about quantum physics, I was little then, and for me it sounded sort of mysterious and trust a kid to forget what was taught, especially when you weren't listening. Anyways back to recent times, my friend instead took me on a journey on quantum computers; he spoke on how they were used to solve complex problems. I remember asking him for the difference between that and normal computers cause I felt they were the same. I also remember asking on his thoughts on the relation between quantum computing, AI and cybersecurity and although he aired his thoughts, that discussion isn't exactly what we're her for now, or is it?. Hello wonderful reader and welcome to another edition of our weekly Techsafe Cybersecurity Awareness blog, and for t...
