Blockchain

Blockchain is a revolutionary technological concept that is changing the way we understand digital transactions.

This technology creates a decentralized digital ledger where all operations are recorded in chronological sequence and spread across an entire network of computers called nodes.

What does blockchain so different?

Spread:

Most traditional databases run on centralized servers. However, blockchain is spread across many different computers, which increases its resistance to attack.

Persistence of records:

Once a block is confirmed and included in the blockchain, it is almost impossible to change its information without affecting subsequent blocks, which would require the majority of the network to agree.

Public access:

Nodes of public blockchains, such as Bitcoin, can check the entire history of transactions, which ensures a high level of transparency.

Okhrana dat:

Due to advanced cryptographic techniques, manipulation of data in blockchain is extremely difficult.

Approval system:

To confirm and add new records to the blockchain, there are mechanisms such as Proof of Work or Proof of Stake that ensure data integrity.

This technology is rapidly expanding into various industries outside of the cryptocurrency world, such as for digital authentication, product tracking in supply chains, or even digital identity management. The decentralization, security and transparency offered by blockchain represent a revolutionary step in the digital world.
