Until now, the information of the blockchain technology has been linked to the news about the operation of bitcoin, the price of this cryptocurrency, etc. However, the blockchain technology is completely transforming the operation of the Internet: "We think that blockchain only has to do with cryptocurrencies but many companies are carrying out very innovative projects with blockchain applications that will change how they work. industries, "says George Levy, certified blockchain and bitcoin instructor at the 'Blockchain Institute of Technology' (BIT) and Udemy, the global online training platform. "For example, it is getting to certify the diamonds thanks to this technology and they are even being born alternative platforms to the traditional stock exchange system based on blockchain". Blockchain, a permanent and secure record Blockchain technology is, in essence, a ledger that keeps a permanent record of all transactions in a chronological, secure and immutable way. All information is protected by advanced cryptography, and blockchain allows to maintain multiple exact copies of the same information, in a decentralized manner, through multiple computers, eliminating the possibility of having a single point of failure. 4 blockchain applications that you did not know
The frauds in the electoral votes could happen to history definitively thanks to the blockchain. There are already several methods and systems based on this technology that ensure that the vote of each person in an election is registered once and is unchangeable, providing transparency and privacy. In this way, they prevent anyone from voting twice or manipulating a vote already registered.
One of the sectors in which the most use is given to this technology is in the food industry. "A well-known chain of department stores is using blockchain in the supply chain of pork products, so that all the information of the process, every step from when the pig is on the farm until it reaches the store is registered in the chain of blocks, "explains Levy. "In this way, food safety is improved, since they can check the origin of each product in a matter of seconds or minutes instead of days or weeks. In addition, the visibility and traceability provided by blockchain helps detect fraud and promote responsible practices around food. "
Blockchain technology can even help to stop conflicts in the diamond industry. The fact that the information registered in the chain of blocks is immutable allows to create reliable 'DNIs' for each diamond. This is precisely what allows to create a system that functions as a global register of these materials. It includes characteristics such as cutting, quality as well as the exact provenance of each one. This allows detecting for example fake diamonds or those that come from war zones.
The certification and authentication of processes, products and services is another of the fields in which the application of blockchain technology is already a reality. Thus, thousands of certificates of authenticity are stored in the chain of blocks in a safe and accessible way.
"The blockchain technology can be combined with Big Data, Artificial Intelligence and the Internet of Things, enhancing the capabilities of each of these, which are just some of the technologies that will change the world the most as we know, "says the instructor. "It will be something similar to what happened with the arrival of the Internet. The labor market will also be affected as thousands of jobs will be changed. It is a new opportunity and we must update ourselves so as not to be left behind "
