The digital age has brought with it several innovations that are set to transform the way we live and work forever. From artificial intelligence (AI) to virtual reality (VR), the world is becoming increasingly digital and connected – which is why blockchain technology has become one of the hottest topics in tech once again. In an age where cyber hacks and data breaches are almost commonplace, many people believe that blockchain technology could be the solution to keeping sensitive information secure once and for all. If you’re struggling to keep up with all these new acronyms or have no idea what we’re talking about, don’t worry - we have everything you need to know about blockchain technology right here...

What is Blockchain?

Blockchain is a digital database that stores all of the transactions that occur within a particular ecosystem. The database itself is distributed across a network of computers or "nodes" that all hold identical copies of the database. Blockchain technology works as a secure digital record of these transactions that cannot be altered retrospectively. This revolutionary technology was developed back in the late 1990s as the core technology behind bitcoin, the first-ever cryptocurrency. Today, blockchain has evolved beyond this, with applications in sectors such as logistics, healthcare, real estate, and more.

Why Is Blockchain So Important?

Blockchain’s distributed ledger technology (DLT) allows for the secure, transparent, and undisputed recording of transactions. It makes use of a network of computers that are linked together and verified using cryptography. With no central authority overseeing the network, blockchain technology is incredibly secure, with data stored in encrypted blocks that can only be accessed with the correct decryption key. Because no single person or organization owns the network, it is impossible to change the data retroactively. Any attempt to tamper with the blockchain would be immediately and automatically detected. This is because every computer in the network will hold an identical copy of the blockchain database, meaning that any changes would be instantly identified. Because no centralized data is stored anywhere, hackers can't gain access to blockchain networks. Furthermore, because the data is recorded across several nodes, it would be difficult for a hacker to shut down the entire network with a single attack.

How Does Blockchain Work?

While blockchain is a relatively new concept, the technology behind it has existed for decades. In the past, database administrators would store all of their information on a centralized server, meaning that the integrity of their data was entirely dependent on the security of that one system. Thankfully, blockchain technology allows for the decentralization of data storage, meaning that information is hosted on multiple nodes across a network. Because no single person or organization owns the network, it is impossible to tamper with blockchain data. Each transaction is verified by the network and recorded as a new “block” within the blockchain, meaning that the entire history of each blockchain is open to the public.

The Importance of Decentralization

As we have seen, blockchain technology is incredibly secure, but it relies on the network to function correctly. To achieve decentralization, each network node must be operated by a different person or organization. It is important to note that decentralization does not mean that one company owns the network, but that there are many owners. Because each node is operated by a different person or organization, it is unlikely that the entire network would ever be shut down by a government or regulatory body. Blockchain networks are decentralized entirely voluntarily, and there is no centralized server that could be threatened by government action. In an era where social media is increasingly being censored and privacy rights are under threat, blockchain technologies could provide a solution to protect freedom of speech.

Where Will We See Blockchain in Practice?

Blockchain technology is likely to be applied to a variety of industries in the future. In financial services, blockchain technology will be used to increase the speed of settlements and the efficiency of supply chains. When applied to the healthcare industry, blockchain can be used to securely store and share sensitive data, including health records. When applied to government and public services, blockchain technology can be used for identity management and the secure transfer of benefits. Blockchain’s potential is truly endless, with several startups already implementing the technology in innovative ways. From decentralized energy grids to self-regulating smart cities, blockchain technologies have the potential to change the world as we know it.

Key takeaway and what we can help you with

Blockchain technology has the potential to transform industries across the board, from financial services to healthcare and beyond. While technology exists as a concept in many industries, it is still in its early stages. As technology improves and becomes more widely used, blockchain is set to revolutionize the way that we live and work. With decentralized networks, blockchain technology could be used to secure communications and protect freedom of speech. It could also be used to store sensitive data, such as health records, securely. Blockchain technology could also be used in government and public services, such as the secure transfer of benefits, and in autonomous networks, such as the smart cities of the future.
Because we love to try everything new, we started our own projects with blockchain. We started to bring our own licenses partly on the blockchain and built our own internal chain to see what we can use it for. If you need assistance in setting up company internal blockchains, we can help you with consulting and creating it for you. For more information contact us.
