In the beginning, the value of the currency was related to the weight of the metal, so its value was intrinsic. Around 1950 the first credit cards were created, i.e., the first attempt to use electronic money to buy goods and services without the need to use cash.
Now it seems that the next step is cryptocurrencies or bitcoin, and this is where a blockchain certification or a fintech course can be very relevant. The aim of the blockchain is the secure, direct, and transparent exchange of any transaction. And not only that, due to the success that the blockchain has had in cryptocurrencies, the financial world is on its way to transforming itself.
What Is Blockchain?
Blockchain is a disruptive technology, which has only just been launched, but which represents a revolution within the internet very similar to what happened in the 1990s. It is a revolution for the financial sector, but also many other aspects, such as the transfer of data and information between individuals.
To put it as simply as possible, what Blockchain technology provides is the creation of a decentralized database, i.e., a database that does not live on the usual internet servers but thousands of users' nodes. This database has certain characteristics. Every block that is introduced into the Blockchain must comply with a series of pre-established rules. Once a block is introduced, it is cryptographically sealed in a process called mining and this information will remain there, immutable, forever.
One of the main benefits of this technology is that it offers the possibility of carrying out economic transactions securely and quickly. Thanks to encryption and encoding, manipulation and possible fraud are prevented. This allows all players to offer global payment alternatives, without putting anyone's security at risk. Another major advantage is the possibility of implementing a transparent system in which the status of registered accounts can be viewed.
The truth is that the Blockchain is not only useful for making economic transactions, but also for storing and securely transferring information, avoiding security breaches. It also ensures that the information is not modified. This technology is increasingly trusted by companies and individuals alike.
Other Benefits of Blockchain
More than just sending data, it proposes a new paradigm in the digital ecosystem. Until the birth of Blockchain technology, everything we worked with copies, if you send an email there are many copies of it on servers, if you send a file anyone can make copies, a website, a video, everything is copies, copies, copies, copies.
Blockchain technology allows us for the first time that, if I send you a digital item, I no longer have it, whether cryptocurrencies, digital collectibles, etc., and this is just one of the many features it can offer.
There are still major technological challenges that blockchain technology has to face, the most important of which is scalability. Today, truly decentralized systems easily become saturated when they reach a high number of users, but there are already many advances on the table to improve this aspect.
We are also seeing the birth of new sectors such as decentralized finance or non-fungible tokens, which have only just been born and are revolutionizing the digital and financial industry. And it is on these topics that our blockchain training focuses.
Thanks to blockchain technology, for the first time the financial sector can move across networks and, most importantly, without intermediaries, from person to person. Blockchain training is becoming popular and the best way to get it is with a fintech course.
