The use of modern information technologies is associated with problems in protecting systems, networks, and programs from digital attacks. The advent of blockchain technology has become an effective solution to protect data from unauthorized access and hacking.
It is predicted that blockchain will dramatically change the cybersecurity of any business, making it possible to store information without the risk of damage, theft, or data loss.
This is a decentralized data registry containing information about all operations performed through peer-to-peer networks. Conducted transactions are recorded in time and are grouped in blocks with feedback. Blocks are cryptographically protected and organized in chains.
The transaction data is immutable and is considered reliable, protected. Blockchain technology allows all users to see any transaction ever committed by anyone on the network.
Peer -to-peer network allows its participants to interact with each other on equal terms. The result of a peer-to-peer connection is that there is no need for central coordination. A large number of nodes ensures the stability of the blockchain chain even when some nodes are inaccessible or infected with malware.
Distributed consensus requires agreement among most nodes for a single data value. This approach allows blockchain technology to validate a single, correct process without central control. Breaking the consensus mechanism is only possible if attackers can use 51 percent of the computing power of a peer-to-peer network.
Security encryption uses cryptography, a form of data protection in which the keys used to encrypt and decrypt data are different. Blockchain technology uses this approach to ensure the security of information as it moves across the network. Cryptography protects completed transactions from any changes, making them immutable.
Blockchain is a breakthrough in cybersecurity for the entire digital world. The new technology will ensure the highest level of confidentiality, accessibility, data security. However, the complexity of its implementation can cause difficulties with development and actual use.
