Blockchain technology has been a very helpful tool for countless segments of the economy because of its secure relationship with cryptocurrencies, digital currencies that use cryptography.
But it is not just cryptocurrencies that blockchain works together, a detail that demonstrates its scope and influence in an increasingly connected world and with the need for technologies that provide more protection.
Considering that practically all areas have some type of data transfer nowadays, it is increasingly evident that blockchain is a technology with great utility and relevance.
There has been a categorical growth in recent years involving the blockchain , which has benefited from its popularity to constantly improve its processes and protect the large volumes of transaction information .
In today’s article, learn how blockchain technology is changing the world and how to adapt to the transformations promoted by it. Follow the content until the end and have a good read.
The definition of blockchain
Blockchain can be understood as a system that is decentralized and gathers various records about various information transactions.
This technology in the form of software allows decisions to be taken without clear and defined leadership.
As it is connected in a network, the blockchain allows the events that happen in it to be marked every time there is an addition of information.
That is, the history of data transactions is continuously recorded and cannot be changed, in addition to granting free access to people to include this data in the network.
Due to the massive amount of information that the blockchain embraces, it functions as a chain of data blocks.
It is from this idea that the name blockchain emerged, joining the English terms “block”, which means block, and “chain”, translated as chain.
Particularities present in the blockchain
Like any technology, blockchain also has its unique features.
Here are some selected particularities that are part of the blockchain for you to know it even more.
Public and unalterable records
Each digital record made on the blockchain is publicly updated by users who have access to the network, and it is also possible to synchronize these changes in each device integrated in this network.
The advantage is that all this history of changes cannot be modified freely, without express authorization.

End-to-end encryption
The entire blockchain registration process is end-to-end encrypted through an algorithm that encodes information transactions.
In this way, it is only possible to decrypt the data with an access key, ensuring that the information is really safe with the blockchain.
Privacy about your own identity
Another characteristic detail of the blockchain is the possibility of preserving the identity of who is accessing the network.
Each person can decide whether they want to remain anonymous or disclose their identification, but this does not mean that malicious changes occur without it being possible to track who actually made the changes.
Blockchain is already changing the world
The changes brought about by blockchain are already perceptible in our daily lives, even though we do not have a clear idea of the influence of this technology around the world.
The impacts of blockchain can be seen in some fields that we will list below.
Health area
Healthcare, which is extremely important for everyone, is managing to benefit from blockchain technology.
Hospitals and medical centers have the autonomy to control information about appointments, medications and the like on account of the blockchain.
Because it is a significant segment, the protection of health data is essential and helps to keep them free from tampering.
Voting systems
Voting is a right that the population has to express their opinion directly. With the blockchain, voting systems ensure more transparency in the fulfillment of democracy.
Removing the possibility of corruption, the blockchain not only guarantees clean elections, but also shows the electorate that the secrecy of each vote is maintained without interference.
Car rent
Did you need to rent a car? So know that blockchain also has involvement in this feature.
Car rental payments already rely heavily on the blockchain, where a decentralized application records financial transactions and grants the benefit of automatic debit.
Since it is a digital transaction, the blockchain guarantees that the operation takes place with guaranteed security and efficiency, protecting the company and the lessor in this relationship.
Digital contracts
When there is a need to sign a digital contract with various confidential information, the blockchain presents itself as a very useful security technology.
It is based on blockchain data encoding that the points of this contract are secure in a completely technological way.
Internet of Things (IoT)
The Internet of Things (IoT) is another area that clearly benefits from blockchain technology.
Encompassing electronic devices, houses, vehicles and many other examples, the Internet of Things needs to protect itself against any threat against its information.
The characteristic interconnection of the Internet of Things (IoT) gains an efficient protection barrier to combat unwanted invaders through the blockchain, which decentralizes the information of this technology.
Communication
Fast, stable and secure communication is everyone’s desire, isn’t it? Know that the blockchain also acts in this area.
Digital communication built with cryptographic algorithms is a trend that is here to stay, as the blockchain is able to protect communications made on electronic devices and record interactions.
