Blockchain technology. Due to many ups and downs, especially negative news mainly related to cryptocurrencies, doubts remain whether the Blockchain is the technology of the future or just another scum. Let’s take a closer look on this.
Blockchain is a decentralized database in peer-to-peer (p2p) architecture used to store and send information about transactions or payments. Transactions (or nodes) create blocks, which size depends from the used implementation. If the block is filled with information, another block of data is automatically created as part of the chain of blocks. In blocks we can store e.g information about ownership status, commercial transactions, electricity bills or cryptocurrency. Due to its multiple applications Blockchain is also gaining popularity in public administration and banking.
The peer-to-peer network that characterizes Blockchain does not require any central computers or management systems. Every single computer in the network has the same access when it comes to transferring and authentication of transactions. The users who share the computing power of their devices (so-called miners) for block digging usually receive reward in form of tokens.
The main benefits of using blockchain technology are:
Cryptocurrency is a medium of exchange functioning in digital world, formed on the basis of cryptography. Generally speaking, cryptocurrency as a digital currency has to do with the use of tokens based on the distributed ledger technology, which stands for Blockchain. Cryptocurrency is used for operations on a Blockchain network, when it comes to buying, selling, investing, trading.
Besides playing “monetary tool” role cryptocurrencies are a driving motor for startups. It works for great ideas seeking for financial support. Startups create an initial price offering (ICO) by issuing tokens which are supposed to finance the idea standing behind the business. Thanks to ICO, startups can collect very large funds to kick off its projects.
ICO is one of the earliest stages in the life of every cryptocurrency. This is the moment when a coin is “offered” to a community that somehow identifies with the project or a company. Usually, for each ICO phase, we have a fixed price for which we can buy a coin. If we find a promising project or a company product and we are able assess overall credibility, we can very easily invest in a given undertaking.
However, as the great history of frauds shows, there are many cases where startups disappear after collecting a few million dollars. That is why many countries set up legal rules for carrying out the ICO.
In Asian countries such as South Korea and China ICO has been banned, while in Europe – Malta is leading the way and still openly invites Blockchain startups.
Cryptocurrencies as many other digital assets have security issues. Media storm about hacker attacks on cryptocurrency exchanges do not help perceive Blockchain as a safe technology. The biggest attacks this year were:
– 500 million NEM (about $533 million) for the Japanese Coincheck Stock Exchange,
– 17 million Nano (about $187 million) million for the Italian BitGrail stock exchange,
adding smaller incidents of fraud, the sum of stolen money reaches almost $1 billion. It is over 3 times more than in 2017.
Unfortunately, all attacks were a consequence of poor stock market security. But the negative patch was pinned not only to cryptocurrencies but to the Blockchain itself. The main consequences of these events were huge declines on stock exchanges. For example, Bitcoin with its ATH (all-time-high) $20.000 now drifts at a horizontal about $4.000.
Despite many negative news, we should not underestimate Blockchain technology. Many projects that have accumulated huge funds during ICO are still working hard to implement the promised functionalities in their Whitepapers (project analysis and description of milestones) and now are slowly entering the decisive phase.
There are also positive news, whereas many banks and global corporations confirm the use of Blockchain in their promising projects. Time will tell us if Blockchain will revolutionize the IT world, but one thing is sure – although this technology had its beginning over 10 years ago it is still being developed and improved by a huge community of IT and high technology experts.
We are convinced that there are still many positive news awaiting us. One of Blockchain enthusiasts, – the director of the Bitcoin Foundation, Brock Pierce said: “This innovation is more substantial than the internet. The blockchain is going to have an even larger impact.”. This can be true.
The demand for skilled software developers is constantly growing while the number of local talents is limited. As a result, companies lack experienced developers because in the given area there are not enough specialists in a certain technology. To overcome the problem and still be able to grow with talented people around, companies started practicing Staff Augmentation. The service comes […]
When you devoted so much time and resources, creating your app, an online platform, or a system, you can fall into a misconception that your work now is finally “done”. Where in fact, whatever you brought up to this world has to be continuously improved in order to meet the ever-changing market trends. While this is obvious for some, the […]
Regardless of whether you have an idea for a product or your product already exists, choosing to work on it with remote software engineers is a great decision. What’s more, it’s a direction in which many companies are heading right now. From one side, there is the current pandemic that pushed some firms to start practicing such a strategy but […]
