Blockchain, an unstoppable revolutionary technology

For many, this term is unfamiliar, yet it actually functions in our environment on a daily basis. Blockchain is a unique system for making, settling and recording transactions. Everything takes place in so-called blocks. The best example of blockchain is bitcoin-this term is surely already closer to you, right? What is blockchain in reality and what does this technology lead to? Blockchain is currently on many people’s tongues, there is a lot of talk about it, so it is not surprising that this technology is a breakthrough in data collection and storage. It is used in departments that deal with business and financial matters. It also has its uses in banking, startups and others.

Blockchain-what it is and how it works

Blockchain is a type of distributed database that has the capability to record and monitor the resources inside the network, which was created by its users. Each user has access to the database, and they also have the ability to verify it. This database is well secured through the use of sophisticated cryptographic tools. In blockchain, data is stored in blocks. When a given block is fully occupied with information, another and another is created – this leads to the formation of a ledger, which contains a collection of all transactions that are contained in the blockchain. Among the main tasks of blockchain is building a ledger of transactions, which is decentralized. The data that is entered is immutable, meaning that it cannot be undone in any way. Everything is supervised by security, and if any user makes any attempt to change something, the system will immediately detect the transaction and refuse to accept it.

Is blockchain secure?

Forging the blockchain is an impossible operation, and the transactions stored in the blocks are irreversible. The system is based on advanced mathematical methods and cryptographic security. The blocks are secured by hashes, or what? So are unique signatures that are assigned to each block.

Blockchain-their application

Bitcoin cryptocurrency is one of the types of transactions that are made in blocks. Blockchain has applications primarily in storing various transactions. This technology may soon be widely used in banking ledgers, document authentication systems, digital signatures in government.
